A practical guide to GPU hardware

The GPU Buying Guide.

Compare the hardware that matters for your workload. Start with memory and system format, then check software, cooling, and the complete server before requesting a price.

Hardware sourcing

Start with the workload. We can help narrow the build.

Tell us the GPU, quantity, destination, and timing you have in mind. We will check the configuration and current channel availability before giving you a price or delivery estimate.

Rent capacity

Useful for short projects, uneven demand, or testing a workload before buying hardware. Compare the GPU model, memory, interconnect, data location, and total hours you expect to use.

Buy hardware

Useful when demand is sustained and you can operate the system. Include power, cooling, network, support, and replacement planning in the cost comparison.

There is no universal break-even point. Utilization, cloud contract rates, facility cost, financing, and resale value change the result.

Start with memory and system format.
HBMSXMOAMROCM

More memory can keep a larger model or batch on fewer GPUs. Software compatibility, network topology, and the complete server still decide whether a part fits your workload.

H100 SXM.

Established CUDA platform

A familiar starting point when CUDA support and an established HGX platform matter most.

H100 SXM has 80 GB of HBM3 memory per GPU. Ask for a complete HGX server and check whether the memory capacity fits your model and batch size.

H200 SXM.

More HBM for the same software stack

H200 gives a memory-constrained CUDA workload more room before changing platforms.

H200 SXM has 141 GB of HBM3e memory and 4.8 TB/s of peak memory bandwidth per GPU. Compare the actual OEM server, power configuration, network, and support terms in the quote.

B200 SXM.

Quote the whole HGX system

B200 is a system purchase. The server build and facility fit matter as much as the GPU count.

HGX B200 uses eight SXM GPUs with 180 GB of HBM3e each. NVIDIA supports air- and liquid-cooled partner designs. Confirm the OEM server, cooling, power, interconnect, and whether the requested quantity maps to available system configurations.

MI300X.

Large memory on ROCm

MI300X is worth testing when model memory is a constraint and the workload can run on ROCm.

MI300X provides 192 GB of HBM3 memory per GPU. Review framework and kernel support on your actual workload before committing to an AMD server.

MI355X.

Facility planning comes first

The extra HBM is useful only if the server and cooling plan fit the deployment.

MI355X provides 288 GB of HBM3e and up to 8 TB/s peak memory bandwidth per GPU. AMD specifies direct liquid cooling for this 1,400 W accelerator. Validate the exact OEM platform and facility requirements.

GPU and quantity

Model, GPU count, and whether a complete server or rack is needed.

02

Workload

Training or inference, model size, framework, and any CUDA or ROCm requirement.

05

Commercial terms

Written configuration, current price, delivery estimate, warranty, and support.

For an HGX B200 request, tell us whether the GPU count is exact or can be adjusted to complete 8-GPU systems. We can then ask suppliers about feasible server counts and configurations.

Specifications

Memory, bandwidth, format, and cooling details above come from manufacturer documentation. Check the final OEM bill of materials before ordering.

Send us the build you have in mind.

A rough spec is enough to start. We will work through the configuration, then confirm current pricing, delivery, and warranty terms in writing.
