GPU MODELS / ALTERNATIVES TO A100 80GB PCIE
Alternatives to the A100 80GB PCIe
The PCIe form of the A100 80GB trades the SXM module's NVLink fabric for drop-in compatibility with standard servers. Same memory, same tensor cores, lower power cap. For single-GPU and two-card work it performs identically to the SXM part; for 8-way training the SXM version's NVLink is worth the premium.
People usually compare the A100 80GB PCIe against A100 80GB SXM. Prices below are live on-demand published rates from the panel.

WHEN EACH ALTERNATIVE WINS
A100 80GB SXM
Same chip, same 80 GB, slightly lower power cap and bandwidth (1.9 vs 2.0 TB/s). The real difference is NVLink: SXM nodes link eight GPUs at 600 GB/s each; PCIe tops out at bridge-linked pairs. Multi-GPU training belongs on SXM.
A100 80GB PCIE ALTERNATIVES - FAQ
What is the best alternative to the A100 80GB PCIe?
It depends on the workload. A100 80GB SXM: The A100 80GB was the standard large-model training chip of 2021-2023 and still anchors an enormous installed base. Live rates for each are in the table above.
Why look for A100 80GB PCIe alternatives?
8-way training nodes - without SXM NVLink, multi-GPU scaling stalls on PCIe.
How much does the A100 80GB PCIe cost compared to its alternatives?
Each alternative's current cheapest published rate is listed in the table above; figures recompute hourly from provider-published prices.
