Multi-GPU Systems

AI Servers — Total System Compute

A multi-GPU server isn't judged like a single card — what matters is its combined compute across every GPU inside it. Total Compute below takes the matched per-card FP16 TFLOPS figure from the table above and multiplies it by GPU count, so servers stay on the same benchmark scale. 48 systems currently in our AI Hardware catalog — tap any name for full specs and pricing.

Methodology

What These Numbers Mean

1

Collect published benchmarks

We start from publicly published GPU-cloud benchmark data — verifiable numbers anyone can check, no in-house guesswork.

GPU hardware being benchmarked on the test bench
2

Score three real workloads

Every card is measured across LLM inference, image generation and vision — the work AI hardware actually does all day.

LLM Inference

Token-generation speed across popular open-weight models, from lightweight 8B assistants to 70B+ heavyweights.

Image Generation

Diffusion-model throughput and latency, covering everything from fast turbo pipelines to production-quality renders.

Vision & OCR

Multimodal image understanding and document OCR throughput under realistic concurrent load.

Inside a multi-GPU AI server running real workloads
3

Index everything to RTX 3090 = 100

All scores land on one 100-point scale with the RTX 3090 as the baseline — so any two cards compare at a glance.

Training Throughput

An independently published single-GPU figure (images/sec), shown where a matching benchmark exists for that exact card.

Rows of GPU racks in the data center

Reference data for orientation only — real-world results vary with software stack, drivers, batch size and workload. Not a guarantee of performance.

FAQ

Common Questions

What does the AI Inference Index mean?

It is a single relative number showing how a GPU performs across LLM inference, image generation and vision workloads combined, scaled so the RTX 3090 always equals 100. A score of 200 means roughly twice the aggregate throughput of an RTX 3090.

Which GPU has the highest AI Inference Index?

The RTX Pro 6000 Blackwell currently leads our ranking with an AI Inference Index of 403 — roughly four times the aggregate inference throughput of the RTX 3090 baseline — paired with 96 GB of VRAM for the largest LLMs without quantization.

What is the best value GPU for AI inference?

The RTX 5090 (AI Inference Index 207, 32 GB) and RTX 4090 (index 133, 24 GB) offer the strongest price-to-performance for single-GPU inference and image generation. The RTX 4090 Pro variant adds 48 GB of VRAM for larger models while keeping consumer-class value.

What is the best GPU for running large language models?

For the largest LLMs served without quantization, flagship data-center cards like the RTX Pro 6000 Blackwell (96 GB), H200 (141 GB) and Instinct MI300X (192 GB) give you the memory headroom to keep whole models resident. For 8B to 30B models, a single RTX 5090 or RTX 4090 delivers excellent throughput at a fraction of the cost.

Can I buy this hardware from MillionMiner?

Yes — current-generation NVIDIA GPUs and full AI servers are available through our AI Hardware catalog, with worldwide DDP shipping and B2B pricing on request.

Why is the RTX 3090 the baseline?

It is one of the most widely deployed AI-capable GPUs, making it a practical, well-understood reference point for comparing newer and older hardware.

Does more VRAM always mean better performance?

No. VRAM determines which model sizes and batch sizes fit at all — it does not by itself determine speed. A card with less VRAM can still post a higher inference index if its architecture and memory bandwidth are stronger.

Which GPU has the most VRAM for large AI models?

The AMD Instinct MI350X leads at 288 GB, followed by the MI325X at 256 GB. Among NVIDIA cards the B100 SXM offers 192 GB and the H200 provides 141 GB of high-bandwidth memory. More VRAM lets you load bigger models and larger batches without splitting them across multiple GPUs.

What is the difference between the AI Inference Index and FP16 TFLOPS?

FP16 TFLOPS is a theoretical peak compute figure published by the manufacturer — a raw hardware ceiling. The AI Inference Index is a measured, workload-based score built from published benchmarks across LLM, image and vision tasks. A card can show high theoretical TFLOPS yet a lower real-world index when memory bandwidth or software support holds it back.

How do the NVIDIA H100 and H200 compare?

Both are Hopper-architecture data-center GPUs rated at 989.5 FP16 TFLOPS. The difference is memory: the H200 carries 141 GB of faster HBM3e versus 80 GB on the H100, so it serves larger models and longer context windows at higher sustained throughput. For most new LLM-serving deployments the H200 is the stronger choice.

Can I compare two specific GPUs head-to-head?

Yes. Use the comparison Arena on this page to pick any two of our 78 listed GPUs and see their AI Inference Index, VRAM, FP16 TFLOPS and training throughput side by side, with the winner of each metric highlighted.

What GPU do I need to train AI models rather than only run them?

Training is far more memory- and compute-intensive than inference, so it favors flagship cards with large VRAM and high FP16 TFLOPS such as the H100, H200, B200 or Instinct MI300X class. Our Training Throughput column shows single-GPU images per second where a published benchmark exists — for example 1,396 img/s on the A100 40GB versus 905 on the RTX 3090.

Do you also sell complete multi-GPU AI servers?

Yes. Alongside 78 individual GPUs we list 48 complete multi-GPU AI servers, including HGX and DGX-class systems built around H100, H200 and Blackwell accelerators, ready for large-scale training and production inference. Contact us for configuration and B2B pricing.

Do the benchmarks include AMD and Intel GPUs, or only NVIDIA?

All three are covered. Alongside the full NVIDIA line-up we include AMD Instinct accelerators (MI350X, MI325X, MI300X, MI250X) and Radeon cards, plus Intel Gaudi 3 and Arc, so you can compare across vendors on one consistent index.

How accurate are these benchmark numbers?

Every figure is drawn from publicly published benchmark and manufacturer data, aggregated into a consistent index for orientation. Real-world results vary with software stack, drivers, batch size and workload, so treat the numbers as a comparative guide rather than a guarantee of performance.

How often is this data updated?

We review and refresh figures as new GPU generations launch and as more benchmark data becomes available.
