AMD MI355X GPU Guide – Use Cases & Decision Guide

Introduction – Why MI355X Matters in 2026

Quick Summary: What makes the AMD MI355X GPU stand out for today’s generative‑AI and HPC workloads? In short, it offers massive on‑chip memory, new low‑precision compute engines, and an open software ecosystem that together unlock large‑language‑model (LLM) training and inference at lower cost. With 288 GB of HBM3E memory and 8 TB/s bandwidth, the MI355X can run models exceeding 500 billion parameters without partitioning them across multiple boards. It also delivers up to 4× generational performance over its predecessor and a 35× leap in inference throughput, while new FP4 and FP6 datatypes reduce the energy and cost per token. In this guide you’ll learn how MI355X is engineered, what workloads it excels at, and how to integrate it into a modern AI pipeline using Clarifai’s compute orchestration and local‑runner tools.

Large language models continue to grow in size and complexity. Competitive GPUs have been squeezed by two conflicting pressures: more memory to fit bigger context windows and higher compute density for faster throughput. AMD’s MI355X addresses the memory side head‑on, employing ten HBM3E stacks plus a large on‑die Infinity Cache to deliver 50 % more capacity and 51 % more bandwidth than the MI300X. It is also part of a flexible Universal Baseboard (UBB 2.0) that supports both air‑ and liquid‑cooled servers and scales to 128 GPUs for more than 1.3 exaFLOPS of low‑precision compute. Clarifai’s platform complements this hardware by allowing you to orchestrate MI355X clusters across cloud, on‑prem or edge environments and even run models locally using AI Runners. Together, these technologies provide a bridge from early prototyping to production‑scale AI.

Decoding the Architecture and Specifications

The MI355X is built on AMD’s CDNA 4 architecture, a chiplet‑based design that marries multiple compute dies, memory stacks and a high‑bandwidth interconnect. Each GPU includes eight compute chiplets (XCDs), yielding 16,384 stream processors and 1,024 matrix cores to accelerate tensor operations. These cores support native FP4 and FP6 datatypes that pack more operations per watt than traditional FP16 or FP32 arithmetic. A high‑level spec sheet looks like this:

Behind these numbers are architectural innovations that differentiate the MI355X:

• Chiplet design with Infinity Fabric mesh. Eight compute dies are linked by AMD’s Infinity Fabric, enabling high‑bandwidth communication and effectively pooling memory across the board. The total peer‑to‑peer bandwidth of 1.075 TB/s ensures that distributed workloads like mixture‑of‑experts (MoE) inference do not stall.
  
  
• Expanded on‑die memory. The 256 MB Infinity Cache reduces pressure on HBM stacks and improves locality for transformer models. Combined with 288 GB of HBM3E, it increases the capacity by 50 % over MI300X and supports single‑GPU models of up to 520 billion parameters.
  
  
• Enhanced tensor‑core microarchitecture. Each matrix core has improved tile sizes and dataflow, and new instructions (e.g., FP32→BF16 conversions) accelerate mixed‑precision compute. Shared memory has grown from 64 KB to 160 KB, reducing the need to access global memory.
  
  
• Native FP4 and FP6 support. Low‑precision modes double the operations per cycle relative to FP8. AMD claims that FP6 delivers more than 2.2× higher throughput than the leading competitor’s low‑precision format and is key to its 30 % tokens‑per‑watt advantage.
  
  
• High‑bandwidth memory stacks. Ten HBM3E stacks deliver 8 TB/s bandwidth, a 51 % increase over the previous generation. This bandwidth is critical for large‑parameter models where memory throughput often limits performance.
  
  

Taken together, these features mean the MI355X is not simply a faster version of its predecessor – it is architected to fit bigger models into fewer GPUs while delivering competitive compute density. The trade‑off is power: a 1.4 kW thermal design requires robust cooling, but direct liquid‑cooling can lower power consumption by up to 40 % and reduce total cost of ownership (TCO) by 20 %.

Expert Insights (EEAT)

• Memory is the new currency. Analysts note that while raw throughput remains crucial, memory capacity has become the gating factor for state‑of‑the‑art LLMs. The MI355X’s 288 GB of HBM3E allows enterprises to train or infer models exceeding 500 billion parameters on a single GPU, reducing the complexity of partitioning and communication.
  
  
• Architectural flexibility encourages software innovation. Modular’s developers highlighted that the MI355X’s microarchitecture required only minor kernel updates to achieve parity with other hardware because the design retains the same programming model and simply expands cache and shared memory.
  
  
• Power budgets are a balancing act. Hardware reviewers caution that the MI355X’s 1.4 kW power draw can stress data center power budgets, but note that liquid cooling and improved tokens‑per‑watt efficiency offset this in many enterprise deployments.
  
  

Performance and Benchmarks – How Does MI355X Compare?

One of the most common questions about any accelerator is how it performs relative to competitors and its own predecessors. AMD positions the MI355X as both a generational leap and a cost‑effective alternative to other high‑end GPUs.

Generational Uplift

According to AMD’s benchmarking, the MI355X delivers up to 4× peak theoretical performance compared with the MI300X. In real workloads this translates to:

• AI agents: 4.2× higher performance on agent‑based inference tasks like planning and decision making.
  
  
• Summarization: 3.8× improvement on summarization workloads.
  
  
• Conversational AI: 2.6× boost for chatbots and interactive assistants.
  
  
• Tokens per dollar: MI355X achieves 40 % better tokens per dollar than competing platforms when running 70B‑parameter LLMs.
  
  

From a precision standpoint, FP4 mode alone yields a 2.7× increase in tokens per second over MI325X on the Llama 2 – 70B server benchmark. AMD’s structured pruning further improves throughput: pruning 21 % of Llama 3.1 – 405B’s layers leads to an 82 % throughput gain, while a 33 % pruned model delivers up to 90 % faster inference with no accuracy loss. In multi‑node setups, a 4‑node MI355X cluster achieves 3.4× the tokens per second of a previous 4‑node MI300X system, and an 8‑node cluster scales nearly linearly. These results show that the MI355X scales both within a card and across nodes without suffering from communication bottlenecks.

Competitive Positioning (without naming competitors)

Independent analyses comparing MI355X to the leading alternative GPU highlight nuanced trade‑offs. While the competitor often boasts higher peak compute density, the MI355X’s memory capacity and FP6 throughput enable 1.3–2× higher throughput on large models such as Llama 3.1 – 405B and DeepSeek‑R1. Analysts at BaCloud estimate that MI355X’s FP6 throughput is over double that of the competitor because AMD allocates more die area to low‑precision units. Furthermore, the 288 GB HBM3E allows MI355X to run bigger models without splitting them, whereas the competitor’s 192 GB memory forces pipeline or model parallelism, reducing effective tokens‑per‑watt.

Concurrency and High‑Utilization Scenarios

AMD’s distributed inference research shows that MI355X shines when concurrency is high. The ATOM inference engine, developed as part of ROCm 7, fuses memory‑bound kernels and manages key/value caches efficiently. As concurrency grows, MI355X maintains higher throughput per GPU than the competition and scales well across multiple nodes. Multi‑node experiments show smooth scaling up to 8 GPUs for latency‑sensitive workloads.

Expert Insights (EEAT)

• Structured pruning isn’t just academic. AMD’s MLPerf submission demonstrates that pruning 21–33 % of an ultra‑large LLM can yield 82–90 % higher throughput without hurting accuracy. Enterprise ML teams should consider pruning as a first‑class optimization, especially when memory constraints are tight.
  
  
• Low‑precision modes require software maturity. Achieving MI355X’s advertised performance hinges on using the latest ROCm 7 libraries and frameworks optimized for FP4/FP6. Developers should verify that their frameworks (e.g., PyTorch or TensorFlow) support AMD’s kernels and adjust training hyperparameters accordingly.
  
  
• Tokens per watt matters more than peak TFLOPS. Benchmarkers caution that comparing petaFLOP numbers can mislead; tokens per watt is often a better metric. MI355X’s 30 % tokens‑per‑watt improvement stems from both hardware efficiency and the ability to run larger models with fewer GPUs.
  
  

Memory Advantage & Model Capacity

In LLM and agentic‑AI tasks, memory limits can be more restrictive than compute. Each additional context token or expert layer requires more memory to store activations and KV caches. The MI355X addresses this by providing 288 GB of HBM3E plus a 256 MB Infinity Cache, enabling both training and inference of 520 billion‑parameter models on a single board. This capacity increase has several practical benefits:

1. Fewer GPUs, simpler scaling. With enough memory to hold a large model, developers can avoid model and pipeline parallelism, which reduces communication overhead and simplifies distributed training.
   
   
2. Bigger context windows. For long‑form chatbots or code generation models, context windows can exceed 200 k tokens. The MI355X’s memory can store these extended sequences without swapping to host memory, reducing latency.
   
   
3. Mixture‑of‑Experts (MoE) enablement. MoE models route tokens to a subset of experts; they require storing separate expert weights and large activation caches. The 1.075 TB/s cross‑GPU bandwidth ensures that tokens can be dispatched to experts across the UBB 2.0 baseboard.
   
   

Shared Memory Across Multiple GPUs

The UBB 2.0 design pools up to 2.3 TB of HBM3E when eight MI355X boards are installed. Each board communicates through Infinity Fabric links with 153 GB/s per link, ensuring quick peer‑to‑peer transfers and memory coherence. In practice this means that an 8‑GPU cluster can train or infer models well beyond one trillion parameters without resorting to host memory or NVMe offload. Cloud providers like Vultr and TensorWave emphasize this capability as a reason for early adoption.

Expert Insights (EEAT)

• Memory reduces TCO. Industry analyses show that memory‑rich GPUs allow organizations to run larger models on fewer boards, reducing not only hardware costs but also software complexity and operational overhead. This leads to a 40 % TCO reduction when paired with liquid cooling.
  
  
• Single‑GPU fine‑tuning becomes practical. Fine‑tuning large LLMs on a single MI355X is feasible thanks to the 288 GB memory pool. This reduces synchronization overhead and speeds up iterative experiments.
  
  
• Don’t neglect Infinity Cache and interconnect. The 256 MB Infinity Cache significantly improves memory locality for transformer attention patterns, while the Infinity Fabric interconnect ensures that cross‑GPU traffic does not become a bottleneck.
  
  

Use Cases & Workload Suitability

Generative AI & LLMs

The MI355X is particularly well‑suited for large language models, especially those exceeding 70 billion parameters. With its massive memory, you can fine‑tune a 400B‑parameter model for domain adaptation without pipeline parallelism. For inference, you can serve models like Llama 3.1 – 405B or Mixtral with fewer GPUs, leading to lower latency and cost. This is especially important for agentic AI systems where context and memory usage scale with the number of agents interacting.

Creative examples include:

• Enterprise chatbot for legal documents: A law firm can load a 400B‑parameter model into a single MI355X and answer complex legal queries using retrieval‑augmented generation. The large memory allows the bot to keep relevant case law in context, while Clarifai’s compute orchestration routes queries from the firm’s secure VPC to the GPU cluster.
  
  
• Scientific literature summarization: Researchers can fine‑tune an LLM on tens of thousands of academic papers. The GPU’s memory holds the entire model and intermediate activations, enabling longer training sequences that capture nuanced context.
  
  

High‑Performance Computing (HPC)

Beyond AI, the MI355X’s 78.6 TFLOPS FP64 performance makes it suitable for computational physics, fluid dynamics and finite‑element analysis. Engineers can run large‐scale simulations, such as climate or structural models, where memory bandwidth and capacity are crucial. The Infinity Cache helps smooth memory access patterns in sparse matrix solves, while the large HBM memory holds entire matrices.

Mixed AI/HPC & Graph Neural Networks

Some workloads blend AI and HPC. For example, graph neural networks (GNNs) for drug discovery require both dense compute and large memory footprints to hold molecular graphs. The MI355X’s memory can store graphs with millions of nodes, while its tensor cores accelerate message passing. Similarly, finite element models that incorporate neural network surrogates benefit from the GPU’s ability to handle FP64 and FP4 operations in the same pipeline.

Mid‑Size & Small Models

Not every application requires a multi‑hundred‑billion‑parameter model. With Clarifai’s Reasoning Engine, developers can choose smaller models (e.g., 2–7 B parameters) and still benefit from low‑precision inference. Clarifai’s blog notes that small language models deliver low‑latency, cost‑efficient inference when paired with the Reasoning Engine, Compute Orchestration and Local Runners. Teams can spin up serverless endpoints for these models or use Local Runners to serve them from local hardware with minimal overhead.

Expert Insights (EEAT)

• Align model size with memory footprint. When selecting an LLM for production, consider whether the model’s parameter count and context window can fit into a single MI355X. If not, structured pruning or expert routing can reduce memory demands.
  
  
• HPC workloads demand FP64 headroom. While MI355X shines at low‑precision AI, its 78 TFLOPS FP64 throughput still lags behind some dedicated HPC GPUs. For purely double‑precision workloads, specialized accelerators may be more appropriate, but the MI355X is ideal when combining AI and physics simulations.
  
  
• Use the right precision. For training, BF16 or FP16 often strikes the best balance between accuracy and performance. For inference, adopt FP6 or FP4 to maximize throughput, but test that your models maintain accuracy at lower precision.
  
  

Software Ecosystem & Tools: ROCm, Pruning & Clarifai

Hardware is only half of the story; the software ecosystem determines how accessible performance is. AMD ships the MI355X with ROCm 7, an open‑source platform comprising drivers, compilers, libraries and containerized environments. Key components include:

• ROCm Kernels and Libraries. ROCm 7 offers highly tuned BLAS, convolution and transformer kernels optimized for FP4/FP6. It also integrates with mainstream frameworks like PyTorch, TensorFlow and JAX.
  
  
• ATOM Inference Engine. This lightweight scheduler manages attention blocks, key/value caches and kernel fusion, delivering superior throughput at high concurrency levels.
  
  
• Structured Pruning Library. AMD provides libraries that implement structured pruning techniques, enabling 80–90 % throughput improvements on large models without accuracy loss.
  
  

On top of ROCm, software partners have built tools that exploit MI355X’s architecture:

• Modular’s MAX engine achieved state‑of‑the‑art results on MI355X within two weeks because the architecture requires only minimal kernel updates.
  
  
• TensorWave and Vultr run MI355X clusters in their cloud, emphasizing open‑source ecosystems and cost‑efficiency.
  
  

Clarifai’s Compute Orchestration & Local Runners

Clarifai extends these capabilities by offering Compute Orchestration, a service that lets users deploy any AI model on any infrastructure with serverless autoscaling. The documentation explains that this platform handles containerization, model packing, time slicing and autoscaling so that you can run models on public cloud, dedicated SaaS, self‑managed VPC or on‑premises. This means you can provision MI355X instances in a cloud or connect your own MI355X hardware and let Clarifai handle scheduling and scaling.

For developers who prefer local experimentation, Local Runners provide a way to expose locally running models via a secure, public API. You install Clarifai’s CLI, start a local runner and then the model becomes accessible through Clarifai’s workflows and pipelines. This feature is ideal for testing MI355X‑hosted models before deploying them at scale.

Expert Insights (EEAT)

• Leverage serverless when elasticity matters. Compute Orchestration’s serverless autoscaling eliminates idle GPU time and adjusts capacity based on demand. This is particularly valuable for inference workloads with unpredictable traffic.
  
  
• Hybrid deployments preserve sovereignty. Clarifai’s support for self‑managed VPC and on‑premises deployments allows organizations to maintain data privacy while utilizing cloud‑like orchestration.
  
  
• Local‑first development accelerates time to market. Developers can start with Local Runners, iterate on models using MI355X hardware in their office, then seamlessly migrate to Clarifai’s cloud for scaling. This reduces friction between experimentation and production.
  
  

Deployment Options, Cooling & TCO

Hardware Deployment Choices

AMD partners such as Supermicro and Vultr offer MI355X servers in various configurations. Supermicro’s 10U air‑cooled chassis houses eight MI355X GPUs and claims a 4× generational compute improvement and a 35× inference leap. Liquid‑cooled variants further reduce power consumption by up to 40 % and lower TCO by 20 %. On the cloud, providers like Vultr and TensorWave sell dedicated MI355X nodes, highlighting cost efficiency and open‑source flexibility.

Power and Cooling Considerations

The MI355X’s 1.4 kW TDP is higher than that of its predecessor, reflecting its larger memory and compute units. Data centers must therefore provision adequate power and cooling. Liquid cooling is recommended for dense deployments, where it not only manages heat but also reduces overall energy consumption. Organizations should evaluate whether their existing power budgets can support large MI355X clusters or whether a smaller number of cards will suffice due to the memory advantage.

Cost per Token and TCO

From a financial perspective, the MI355X often lowers cost per query because fewer GPUs are needed to serve a model. AMD’s analysis reports 40 % lower tokens‑per‑dollar for generative AI inference compared to the leading competitor. Cloud providers offering MI355X compute cite similar savings. Liquid cooling further improves tokens per watt by reducing energy waste.

Expert Insights (EEAT)

• Choose cooling based on cluster size. For small clusters or development environments, air‑cooled MI355X boards may suffice. For production clusters with eight or more GPUs, liquid cooling can yield 40 % energy savings and lower TCO.
  
  
• Utilize Clarifai’s deployment flexibility. If you don’t want to manage hardware, Clarifai’s Dedicated SaaS or serverless options let you access MI355X performance without capital expenditure. Conversely, self‑managed deployments provide full control and privacy.
  
  
• Mind the power budget. Always ensure your data center can deliver the 1.4 kW per card needed by MI355X boards; if not, consider a smaller cluster or rely on cloud providers.
  
  

Decision Guide & Clarifai Integration

Selecting the right accelerator for your workload involves balancing memory, compute and operational constraints. Below is a decision framework tailored to the MI355X and Clarifai’s platform.

Step 1 – Assess Model Size and Memory Requirements

• Ultra‑large models (≥200B parameters). If your models fall into this category or use long context windows (>150 k tokens), the MI355X’s 288 GB of HBM3E is indispensable. Competitors may require splitting the model across two or more cards, increasing latency and cost.
  
  
• Medium models (20–200B parameters). For mid‑sized models, evaluate whether memory will limit batch size or context length. In many cases, MI355X still allows larger batch sizes, improving throughput and reducing cost per query.
  
  
• Small models (<20B parameters). For compact models, memory is less critical. However, MI355X can still provide cost‑efficient inference at low precision. Alternatives like small, efficient model APIs might suffice.
  
  

Step 2 – Evaluate Precision and Throughput Needs

• Inference workloads with latency sensitivity. Use FP4 or FP6 modes to maximize throughput. Ensure your model maintains accuracy at these precisions; if not, FP8 or BF16 may be better.
  
  
• Training workloads. Choose BF16 or FP16 for most training tasks. Only use FP4/FP6 if you can monitor potential accuracy degradation.
  
  
• Mixed AI/HPC tasks. If your workload includes scientific computing or graph algorithms, ensure the 78 TFLOPS FP64 throughput meets your needs. If not, consider hybrid clusters that combine MI355X with dedicated HPC GPUs.
  
  

Step 3 – Consider Deployment and Operational Constraints

• On‑prem vs cloud. If your organization already owns MI355X hardware or requires strict data sovereignty, use Clarifai’s self‑managed VPC or on‑prem deployment. Otherwise, Dedicated SaaS or serverless options provide quicker time to value.
  
  
• Scale & elasticity. For unpredictable workloads, leverage Clarifai’s serverless autoscaling to avoid paying for idle GPUs. For steady training jobs, dedicated nodes may offer better cost predictability.
  
  
• Development workflow. Start with Local Runners to develop and test your model on MI355X hardware locally. Once satisfied, deploy the model via Clarifai’s compute orchestration for production scaling.
  
  

Step 4 – Factor in Total Cost of Ownership

• Hardware & cooling costs. MI355X boards require robust cooling and power provisioning. Liquid cooling reduces energy costs by up to 40 %, but adds plumbing complexity.
  
  
• Software & engineering effort. Ensure your team is comfortable with ROCm. If your existing code targets CUDA, be prepared to port kernels or rely on abstraction layers like Modular’s MAX engine or PyTorch with ROCm support.
  
  
• Long‑term roadmap. AMD’s roadmap hints at MI400 GPUs with 432 GB HBM4 and 19.6 TB/s bandwidth. Choose MI355X if you need capacity today; plan for MI400 when available.
  
  

Expert Insights (EEAT)

• Identify critical path first. Decision makers should map the performance bottleneck—whether memory capacity, compute throughput or interconnect—and choose hardware accordingly. MI355X mitigates memory bottlenecks better than any competitor.
  
  
• Use Clarifai’s integrated stack for a smoother journey. Clarifai’s platform abstracts away many operational details, making it easier for data scientists to focus on model development rather than infrastructure management.
  
  
• Consider hybrid clusters. Some organizations pair MI355X for memory‑intensive tasks with more compute‑dense GPUs for compute‑bound stages. Clarifai’s orchestration supports heterogeneous clusters, allowing you to route different tasks to the appropriate hardware.
