GPU Sourcing: 15 NVIDIA and AMD Data Center GPUs

GPU sourcing through GPUSeeker starts here, with 15 NVIDIA and AMD data center GPUs in one place. We’re a concierge-level, vendor-neutral broker for mid-market companies. Each GPU below links to its own sourcing page, with specs, workloads, and answers to common questions. Pick the GPU that fits what your AI teams are building, training, or running in production.

Which GPU fits your AI plan?

Start with the workload, then the memory it needs. Training large models, serving inference in production, and fine-tuning each stress GPUs differently. The blurbs below name who each GPU serves and what for. NVIDIA is listed first, then AMD. Neither maker is ranked.

NVIDIA GPUs

NVIDIA Ampere and Hopper

NVIDIA describes Hopper, including its Transformer Engine and NVLink, on its Hopper architecture page.

  • A100 (NVIDIA Ampere): for teams fine-tuning models and running steady inference without needing the latest generation.
  • H100 (NVIDIA Hopper): for teams training models and running production inference on proven 80 GB HBM3 nodes.
  • H200 (NVIDIA Hopper): for teams serving memory-bound inference, with 141 GB HBM3e for longer context and larger KV caches.

NVIDIA Blackwell and Grace Blackwell

NVIDIA’s Blackwell architecture overview covers the platform behind these four options.

  • B200 (NVIDIA Blackwell): for teams training large models and launching next-wave inference on 180 GB-class GPUs.
  • DGX B200 (NVIDIA Blackwell): for teams that want to own a turnkey eight-GPU system for training and production.
  • GB200 Superchip (NVIDIA Grace Blackwell): for teams pairing one Grace CPU with two Blackwell GPUs for large-model training.
  • GB200 NVL72 (NVIDIA Grace Blackwell): for teams training or serving at rack scale: 72 Blackwell GPUs, one NVLink domain.

NVIDIA Vera Rubin

The NVIDIA Vera Rubin NVL72 page lists the rack’s published specs.

  • DGX Vera Rubin NVL72 (NVIDIA Vera Rubin): for teams planning next-generation AI training or production at rack scale.

AMD Instinct GPUs

AMD lists the CDNA generation of current Instinct GPUs in its ROCm GPU architecture specs.

AMD Instinct CDNA 3

  • MI300X (AMD Instinct CDNA 3): for teams training models or serving memory-heavy inference with 192 GB HBM3 on ROCm.
  • MI325X (AMD Instinct CDNA 3): for teams running memory-heavy inference that need 256 GB HBM3E per GPU.

AMD Instinct CDNA 4

  • MI350X (AMD Instinct CDNA 4): for teams running high-throughput inference on 288 GB HBM3E per GPU.
  • MI355X (AMD Instinct CDNA 4): for teams training large models on dense 288 GB HBM3E systems.
  • MI350P (AMD Instinct CDNA 4): for teams fine-tuning or serving models on air-cooled PCIe servers, with 144 GB HBM3E.

AMD Instinct CDNA 5

AMD places MI430X and MI455X on CDNA 5 in its CDNA architecture overview.

  • MI430X (AMD Instinct CDNA 5): for teams planning converged HPC and AI work with strong FP64 and up to 432 GB HBM4.
  • MI455X (AMD Instinct CDNA 5): for teams planning frontier-scale training and inference on AMD Helios-class racks.

How does GPUSeeker help you source the right GPU?

We find hard-to-source GPU paths and route your requirements to a respected Technology Services Distributor (TSD). The TSD’s solutions engineers build a right-sized proposal across neocloud and channel options. The TSD and its providers handle diligence and contracting. GPUSeeker never handles your data, holds capacity, or quotes prices.

  • Help comparing NVIDIA and AMD options on the same brief
  • Help right-sizing your GPU commitment to your training and production needs before you sign
  • A warm introduction to the right TSD path, with your industry’s compliance needs passed along
