GPU MODELS / ALTERNATIVES TO A100 PCIE
Alternatives to the A100 PCIe
The PCIe A100 brings Ampere tensor cores to standard servers at 250 W. Many providers list it simply as "A100 PCIe" without saying 40 or 80 GB - two very different products at one ambiguous name, and the first thing to ask before renting. Either variant trains well; neither has the SXM part's NVLink fabric.
People usually compare the A100 PCIe against A100 80GB SXM, H100 PCIe. Prices below are live on-demand published rates from the panel.
LOADING LIVE DATA...
| Alternative | Memory | Bandwidth | Cheapest live rate | Head to head |
|---|---|---|---|---|
| A100 80GB SXM | 80 GB HBM2e | 2.0 TB/s | - | A100 PCIe vs A100 80GB SXM |
| H100 PCIe | 80 GB HBM2e | 2.0 TB/s | - | A100 PCIe vs H100 PCIe |
WHEN EACH ALTERNATIVE WINS
A100 80GB SXM
The SXM part adds NVLink 3.0 at 600 GB/s and higher power limits. Same per-card compute; the fabric is what you pay for.
H100 PCIe
The H100 PCIe roughly doubles dense FP16 throughput at a higher hourly rate and the same interconnect limits. For single-GPU work it is the faster option; neither links well.
A100 PCIE ALTERNATIVES - FAQ
What is the best alternative to the A100 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. H100 PCIe: The H100 PCIe puts Hopper's Transformer Engine into standard servers at half the SXM power budget. Live rates for each are in the table above.
Why look for A100 PCIe alternatives?
Multi-GPU training at scale - SXM A100/H100 nodes with NVLink fabric win clearly.
How much does the A100 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.
