A100 SXM 80GB vs A100 PCIe 80GB
Both A100 versions have 80 GB of HBM2e. They differ in form factor and, slightly, in memory bandwidth. Check which one a provider actually lists before comparing its price.
Understand the hardware trade-offs before comparing provider configurations. This page compares GPU models, not cloud SKUs or availability.
What the hardware records show
- Both use the NVIDIA Ampere architecture.
- A100 SXM 80GB uses the SXM form factor and A100 PCIe 80GB uses PCIe. SXM modules sit on server boards built for multi-GPU systems; PCIe cards fit a standard slot. They are separate products with separate offers.
- Both have 80 GB of memory per GPU.
- A100 SXM 80GB has 1.1× the theoretical memory bandwidth (2,039 against 1,935 GB/s).

More memory is useful when your workload needs it.
It does not by itself prove a lower monthly cost, higher tokens per second or a better result. Include model memory, context, batch size and measured performance in your decision.
