There is no universal winner. Choose the accelerator that runs your specific model at the required quality, speed and reliability for the lowest full-system cost—not the chip with the strongest headline benchmark. For a fair decision, compare the chip together with its memory, servers, network, software, deployment access and the engineering needed to use it. Training and inference also need separate evaluations: a platform that suits one may not suit the other.
What are you actually comparing?
“Nvidia GPU versus custom AI chip” can mean two different purchasing decisions: renting a cloud instance or buying physical hardware. Cloud comparisons are between complete services and configurations, not bare chips. A purchased GPU card or server also brings costs and constraints around the host system, networking, power, facility capacity, software and support. Do not compare a cloud hourly rate with a card price and treat the difference as savings.
Here, “custom AI chip” refers chiefly to purpose-built accelerators such as AWS Trainium and Inferentia. AMD Instinct is a GPU alternative, not an ASIC, but it belongs in a workload-based comparison because it offers another accelerator and software platform.
Compare systems, not chip names
NVIDIA describes its benchmark performance as the result of an integrated platform that includes GPUs, interconnect and software. AWS likewise presents Trainium as part of a broader system spanning chips, servers, networking, software and services. The practical unit of comparison is therefore the configuration you can actually deploy, with a specific software release and scale.

How should you choose for training?
Start by defining the training outcome: the model, dataset and target quality, plus the time in which you need to reach it. Then compare platforms against that same task. A single accelerator-speed figure cannot show whether a run will fit in memory, scale across nodes or finish sooner once data loading, checkpointing and software behavior are included.
Training checks that affect cost and completion time
- Model and optimizer memory: Confirm that the model, optimizer state, activations and relevant batch size fit the available memory, or account for the methods needed to distribute or offload them.
- Precision and quality: Compare only results using precision and training settings that meet your quality target. Lower-precision formats can change performance, but a result in one format is not automatically comparable with a result in another.
- Scaling and data flow: Check interconnect performance across the intended number of accelerators, along with data-pipeline behavior and checkpointing. A fast single node does not establish how efficiently a larger job will scale.
- Software and migration: Verify framework and operator support, optimization tools, debugging, checkpoint compatibility and the engineering effort to port or maintain the training job.
- Availability and operating costs: Confirm that the needed instance or hardware configuration is accessible where and when you need it. For owned systems, include power and facility requirements; for rentals, include the complete billed configuration and any surrounding services.
AWS’s decision guide lists EC2 P5/P5e instances with NVIDIA H100 and H200 Tensor Core GPUs for training and inference. The same guide lists Trainium2 in EC2 Trn2 and Trn2 UltraServers, describing Trainium as aimed at deep-learning training of models with 100 billion or more parameters. These are AWS deployment examples, not a complete inventory of NVIDIA hardware or a guarantee that a particular model will run best on either option. Check current region and instance availability, then test your own workload.

How should you choose for inference?
Inference is a serving problem, not simply a smaller training benchmark. The useful comparison is how much output the system can deliver at the quality, latency and reliability your application needs, at realistic concurrency and utilization. A platform that maximizes tokens per second in a benchmark may not be the least expensive way to serve your traffic if it misses your latency target, requires more capacity than you use or changes output quality through different precision or quantization.
Inference measures to define before comparing
- Latency: Set a time-to-first-token target and response-latency percentiles that match the service. Average latency alone can conceal slow responses at peak load.
- Throughput and concurrency: Measure output under realistic request lengths, batch sizes and simultaneous users. Report throughput alongside the per-user speed and latency target.
- Model fit and quality: Check memory requirements, precision, quantization and batching options, and validate output quality for the actual application.
- End-to-end serving cost: Include accelerator time, system utilization, software and operational costs, plus network and storage effects. Compare cost per useful output only when each platform meets the same service target.
AWS describes Inferentia2 in EC2 Inf2 as designed for inference applications, while positioning Trainium for training and inference at scale. NVIDIA GPUs are also deployed for both workloads. These descriptions help identify candidates, but they do not substitute for measuring your model and serving configuration.

What do the available benchmark examples establish?
Published results can help narrow a shortlist, but each applies to its named model, task, system, precision and benchmark setup. Treat vendor-presented claims as evidence about those configurations—not as a price quote or a prediction for your own workload.
| Platform and result | What the result says | What it does not establish |
|---|---|---|
| NVIDIA training platform | NVIDIA’s MLPerf page says its platform delivered the fastest time to train on every MLPerf Training v6 benchmark. NVIDIA says it retrieved the MLCommons results on June 16, 2026, and frames performance as an integrated GPU, interconnect and software result. | It is NVIDIA’s presentation of MLCommons results, not proof that every NVIDIA configuration or workload is fastest. Check the underlying MLCommons submissions for benchmark configurations before drawing comparisons. |
| AMD Instinct MI355X versus NVIDIA B200 | AMD reports that MI355X using MXFP4 came within 5% of a B200 platform using NVFP4 on Llama 2-70B fine-tuning, and within 6% on Llama 3.1-8B pre-training, in the reported MLPerf Training 6.0 comparisons. | The figures cover those specific tasks and different formats; they do not establish a general ranking across models, precisions or platforms. |
| AMD MI300X to MI355X | AMD reports a 3.5x improvement from its first MI300X MLPerf Training 5.0 submission to its MI355X Training 6.0 submission on Llama 2-70B fine-tuning, attributing contributions to hardware, ROCm optimization and MXFP4. | This is a comparison across cited benchmark rounds and versions, not a hardware-only gain or a forecast for other training jobs. |
| NVIDIA GB300 NVL72 inference | NVIDIA Developer reports 2.5 million tokens per second on DeepSeek-R1 for GB300 NVL72 in MLPerf Inference v6.0 (April 2026), up to 2.7 times the system’s debut submission six months earlier. NVIDIA attributes the improvement to TensorRT-LLM updates. | This is a model- and system-specific benchmark result, not a per-user latency or a general serving rate for other models. |
| NVIDIA GB300 NVL72 cost-per-token example | NVIDIA’s inference page cites SemiAnalysis InferenceX for an April 2026 result of $0.123 per million tokens at 116 tokens per second per user on GB300 NVL72. | This dated benchmark figure is not a standing cloud price or procurement quote; it should not be compared with another figure unless workload, service target and accounting basis match. |
NVIDIA also cites Q1 2026 InferenceX results for specified low-latency agentic workloads, claiming up to 50 times higher throughput per megawatt and up to 35 times lower cost per token than Hopper. Those are narrow vendor-presented benchmark claims; the workload and measurement conditions matter, and the figures do not predict savings for a different service.

How do you compare the economics fairly?
Build the comparison around cost to reach an outcome, rather than cost per accelerator or a headline cost-per-token figure. For training, the outcome might be a model meeting a defined quality target by a deadline. For inference, it might be a required volume of acceptable responses while meeting latency and availability targets. A cheaper chip-hour can still cost more overall if it needs more hours, extra engineering or a larger system to deliver that outcome.
For a rented cloud deployment
- Compare the full instance or server configuration and the services needed to run the job, not just the accelerator label.
- Estimate runtime or serving capacity using a representative workload, then include utilization and the cost of capacity that sits idle.
- Account for migration and operations work, especially if the model relies on platform-specific libraries or needs code changes.
- Confirm access in the required region and timeframe before basing a plan on an instance type.
For hardware you buy
- Price the complete system, including host servers, networking and storage—not only accelerator cards.
- Include power and facility requirements, deployment and maintenance, software support and the engineering to keep the system productive.
- Estimate utilization across the period you expect to own the hardware. A system that is economical at sustained high utilization may not be so when demand is intermittent.
- Compare the ownership horizon and replacement assumptions with the alternative of renting equivalent capacity; a one-time purchase price and an hourly rental rate are different cost measures.
No like-for-like market prices are established here for NVIDIA, Trainium, Inferentia or AMD systems. Without matching workload, system scale, utilization, software, geography, service level and date, a direct claim that custom chips are cheaper—or that GPUs are better value—would be unsupported.

What is a practical evaluation process?
- Write down the workload. Specify training or inference, model and version, dataset or representative request mix, quality target, precision, scale and deadline or service-level targets.
- Shortlist accessible systems. Include the relevant NVIDIA GPU option, a suitable purpose-built accelerator where available, and an AMD GPU option if its software and deployment route fit. Verify current access rather than assuming every listed system can be rented or purchased in your location.
- Validate software fit before benchmarking. Run a small representative job to identify unsupported operations, porting work, numerical or quality differences, and checkpoint or serving issues.
- Measure the whole system at realistic scale. For training, record time to the same quality target and scaling behavior. For inference, record output quality, time-to-first-token, latency percentiles and throughput at the same concurrency. Note the software release, precision, system and benchmark conditions.
- Calculate cost per successful outcome. Use the measured time or serving capacity, full system cost, realistic utilization and migration or operating effort. Reject any comparison whose options do not meet the same quality and service targets.
- Recheck availability and assumptions before committing. Cloud offerings, hardware generations and software change; update prices, access, capacity and system details for the region and date of the decision.
Which option should you shortlist?
| Starting point | Why it may fit | What to validate |
|---|---|---|
| NVIDIA GPUs | Consider them when the required model and workflow fit the available NVIDIA system and software stack, for either training or inference. AWS’s guide provides P5/P5e H100 and H200 instances as one cloud route. | Benchmark the complete system and your software release; do not infer workload results from a broad platform ranking or a different model’s inference claim. |
| AWS Trainium | Consider Trainium2 when an AWS Trn2 or Trn2 UltraServer deployment is accessible and Neuron supports the workload. AWS positions Trainium for training and inference at scale. | Test framework and operator fit, migration effort, scaling and full deployment economics for the actual model. |
| AWS Inferentia2 | Consider EC2 Inf2 for an inference workload where its serving behavior and software fit your requirements. | Measure quality, latency, throughput and cost under representative concurrency; confirm current instance availability. |
| AMD Instinct GPUs | Consider Instinct when the ROCm software platform and cloud-partner or OEM deployment route fit the team and workload. AMD describes Instinct for training, inference and fine-tuning. | Validate ROCm support and migration needs, then compare matching model, precision, system and benchmark conditions. |
