Choose an on-premises AI accelerator by starting with the model and service you need to run—not a chip’s headline compute figure. Establish the model, precision, context length, concurrency and latency or throughput target; check that the model, serving runtime and KV cache fit in memory; then benchmark the complete systems you could deploy under the same conditions. There is no evidence-based universal winner across NVIDIA, Intel and AMD for every inference workload.
What should you look for in an AI accelerator?
First define the production workload. The requirements for a small quantized model serving short prompts are not the same as those for a large model with long context, many simultaneous users or strict response-time targets. The workload determines both what the accelerator must hold and what counts as fast enough.

- Model and version: Identify the exact model, including any fine-tune or variant you intend to serve.
- Precision or quantization: Specify the format you plan to use, then verify it is supported through the full software path and that output quality meets your application’s requirements.
- Context and request shape: Set realistic input and output token lengths, including the longest contexts you must support.
- Concurrency: Estimate how many requests the service must handle at once. Batch size and concurrency can change both memory demand and performance.
- Service target: Define request-level goals such as p95 time to first token, inter-token latency, requests per second or generated tokens per second.
- Production path: Include retrieval, preprocessing and other steps that will run in production if they affect the service target.
These details let you rule out configurations that cannot meet the workload before spending time tuning or comparing peak specifications.

There is no single memory number that applies to every model or deployment. The model weights are only part of the requirement: the serving runtime needs memory too, and the KV cache grows with context and concurrent requests. Establish whether the model and expected serving load fit in usable accelerator memory, not merely whether the weight file appears small enough.

Check both capacity and bandwidth. Capacity determines whether the weights, runtime and KV cache can fit. Bandwidth affects how quickly data can move during serving, but neither bandwidth nor peak compute alone predicts the result for your workload. If one accelerator cannot hold the required state, determine whether the model can be sharded across multiple accelerators and whether the added interconnect, complexity and latency fit your service requirements.
Ask vendors or system integrators for the usable memory available to your intended configuration and runtime. Then validate the fit using the exact model, precision, context, concurrency and software you plan to deploy.
How do I compare AI inference chips?
Compare complete systems, not isolated accelerator figures. Use one workload definition and record the configuration and results for every candidate. The checklist below keeps the comparison focused on factors that can change whether a system is usable in production.

| Criterion | What to establish |
|---|---|
| Model fit | Exact model and version, weights, precision or quantization, context length, KV-cache demand, and whether one or multiple accelerators are needed. |
| Memory | Usable accelerator memory after runtime needs, memory bandwidth, and whether sharding or model parallelism is required. |
| Quality and precision | End-to-end support for the intended format and acceptable output quality for the application. |
| Latency and throughput | Request-level latency and generated tokens per second under the same input/output lengths, concurrency and serving setup. Include first-token and token-generation latency where relevant. |
| Software | Framework and runtime support, model kernels and operators, supported operating system and driver versions, deployment tools, and migration or optimization effort. |
| Scale and I/O | PCIe configuration, accelerator-to-accelerator fabric, network interface topology and bandwidth, and whether multi-accelerator or multi-node scaling helps the workload. |
| Facility fit | Server qualification, power delivery, airflow or liquid cooling, thermal limits, and any acoustic or location requirements. |
| Ownership | System purchase and support, availability in your geography, power and cooling costs, maintenance, staffing, integration work and expected useful life. |
Peak-compute specifications can help shortlist products, but they are not comparable end-to-end inference results. Vendor claims may use different models, precisions, software, configurations or test methods. Do not treat them as an apples-to-apples ranking.

Check the software path before buying
A chip’s nominal capability is useful only if your planned stack can use it. Verify that the framework, runtime, model kernels, operators and quantization format support your exact accelerator and model. Confirm supported driver and operating-system versions, container availability, deployment tooling and the effort required to port or tune the application.
Version-specific examples show why this check matters. AMD’s ROCm 6.3.3 documentation describes vLLM validation for named Llama, Mixtral, Mistral and other models, with float16 or float8 options and one- or eight-GPU configurations. Its workflow separates latency and throughput runs and reports generated-token throughput. AMD also cautions that its published ROCm performance data should not be read as peak achievable performance for MI300X/MI325X or ROCm. Treat that documentation as a reproducibility example, not a result that predicts your deployment.
Intel’s Gaudi product information points to PyTorch integration, model support and migration resources, and names Dell, HPE and Supermicro as OEM channels for Gaudi 3 systems. Check the particular system, software versions and models available through the channel you would actually use.

Host and facility constraints can prevent an accelerator from delivering a useful result. Review PCIe slot generation and lane width, placement across CPU sockets and PCIe root ports, host memory channels, accelerator interconnect, networking, storage, cooling and rack power. These details are especially important when the workload spans multiple accelerators or nodes.

NVIDIA’s Certified Systems Configuration Guide recommends balancing GPUs across CPU sockets and PCIe root ports, and choosing slots whose PCIe generation and lane width meet the GPU specification. For the inference-server configuration described in that guide, NVIDIA recommends host memory of at least twice total GPU memory, at least six physical CPU cores per GPU, and a minimum 200 Gbps NIC for multi-node inference. These are recommendations for the described NVIDIA system configuration, not universal requirements for every accelerator or workload. The guide also notes that edge systems can have additional environmental and compliance requirements.
Thermal design matters to sustained performance, not just hardware survival. NVIDIA’s guide states: “Component temperature can impact workload performance, which in turn is affected by environmental, airflow, and hardware selections.” Include the intended room, rack, airflow or liquid-cooling arrangement in system qualification.

Run an evaluation that reflects production
A meaningful benchmark is a controlled test of the serving stack you plan to deploy, not a contest between unrelated vendor charts. Use the same model, request mix, service target and measurement approach on each shortlisted system.
- Choose representative requests. Specify model and version, prompt examples or request shapes, input and output token lengths, precision, and retrieval or preprocessing steps in the production path.
- Set measurable service targets. Define relevant goals such as p95 time to first token, inter-token latency, requests per second, generated tokens per second, concurrency and an output-quality floor.
- Verify support and fit first. Confirm model and runtime support, memory fit, and the exact drivers, libraries, containers and settings before comparing speed.
- Run the same workload on every candidate. Keep the conditions fixed, run long enough to reach sustained thermal behavior, and collect system-level power where possible.
- Record the complete result. Include hardware and server configuration, software versions, workload, measurements, failures, unsupported operations, tuning effort and conditions needed to reproduce the run.
- Validate deployment feasibility. Check OEM or integrator delivery, service and warranty, site power and cooling, expansion options, availability and current pricing for the actual geography and configuration.
Latency and throughput should be read together. A system may handle more generated tokens per second under one test condition yet miss the response-time target or behave differently at the concurrency your service needs. Compare like with like, and retain the workload details alongside every result.
Make the decision on total ownership and operational fit
Once candidates pass the workload and deployment checks, compare the system-level cost and operational burden. Include acquisition and integration, power and cooling, support, maintenance, availability, staffing and expected useful life. Get current prices and delivery estimates for the exact server configuration in your region; a component specification or isolated performance claim does not establish cost-effectiveness.
