What are the A100 SXM and PCIe specs?
| A100 80GB SXM | A100 80GB PCIe | |
|---|---|---|
| Max TDP | 400 W (up to 500 W on CTS SKU) | 300 W |
| Memory | 80 GB HBM2e | 80 GB HBM2e |
| Memory bandwidth | 2,039 GB/s | 1,935 GB/s |
| FP16 Tensor Core | 312 TFLOPS (624 with sparsity*) | Same peak* |
| MIG | Up to 7 instances @ 10 GB | Up to 7 instances @ 10 GB |
Source: NVIDIA A100 product page, read November 5, 2026 (*with sparsity, per NVIDIA's footnote). 40 GB variants also exist and show up in marketplace offers; NVIDIA's table above is the 80 GB SKU. The SXM board is the HGX server version; PCIe is the dual-slot card.
What does one kW of A100 earn per day?
Our assumptions, not sourced: about 550 W per A100 SXM all-in (NVIDIA's 400 W TDP plus about 150 W of server share, our add), so one kilowatt is roughly 1.8 GPUs. Rented 70% of hours, power paid for all 24 hours.
| Power price | Ornn index $1.07/hr | RunPod Community $1.39/hr | Vast median $0.80/hr |
|---|---|---|---|
| Gross / kW / day | $32.68 | $42.46 | $24.44 |
| Net at $0.04/kWh | $31.72 | $41.50 | $23.48 |
| Net at $0.06/kWh | $31.24 | $41.02 | $23.00 |
| Net at $0.08/kWh | $30.76 | $40.54 | $22.52 |
| Net at $0.10/kWh | $30.28 | $40.06 | $22.04 |
Gross = rate × 24 × 70% × (1,000 W / 550 W). Net = gross minus 24 kWh of power. No platform cut, hosting, cooling markup or hardware cost. Our arithmetic on the prices above.
For scale: a kW of Antminer S21 XP (13.5 J/TH, Bitmain) grosses about $2.34 a day at the current hashprice.

How does A100 rent compare to H100?
An A100 SXM is cheaper per hour than an H100 SXM: Vast median $0.80 vs $3.67, RunPod Community $1.39 vs $2.69, Ornn $1.07 vs $3.13 (H100 figures from our H100 page, Nov 6 read; A100 prices on this page are still the Nov 5 read). Per kilowatt the gap shrinks a bit because the A100 draws less (400 W TDP vs up to 700 W), but H100 still clears more revenue per kW at current rents. For consumer cards see the RTX 4090 page.

FAQ
How much does it cost to rent an A100?
On November 5, 2026: a median $0.80 per GPU-hour for one A100 SXM on Vast.ai (23 offers, $0.31 to $1.34) and $0.71 for A100 PCIe (14 offers). RunPod Community listed $1.39 SXM and $1.19 PCIe; Secure Cloud $1.79 for both. The Ornn index of real trades settled at $1.07 on November 4. Lambda's published list shows 8x A100 80 GB at $2.79 per GPU and 1x 40 GB at $1.99 (page says those take effect November 16, 2026).
How much power does an A100 use?
NVIDIA lists the A100 80GB SXM at 400 W max TDP (up to 500 W on a custom thermal solution SKU) and the A100 80GB PCIe at 300 W. A full server draws more per GPU; we assume about 550 W per SXM GPU all-in.
What does one kW of A100 earn per day?
At the $1.07 Ornn rate, 550 W all-in and 70% utilization, about $32.68 gross per kW per day, or about $31.24 after $0.06/kWh power. That is renter price, before platform cut and hardware.
What is the difference between A100 SXM and PCIe?
SXM is the HGX server-board version with 400 W TDP and 2,039 GB/s of memory bandwidth on the 80 GB SKU. PCIe is a dual-slot card at 300 W and 1,935 GB/s. PCIe usually rents for less on marketplaces and on RunPod Community ($1.19 vs $1.39).
Does the A100 come in 40 GB and 80 GB?
Yes. NVIDIA ships both; the 80 GB SKU has HBM2e at over 2 TB/s on SXM. Vast.ai single-GPU offers on November 5 mixed 40 GB and 80 GB cards (14 of 23 SXM offers were 40 GB). Check the listing before you rent.
Does A100 rental beat Bitcoin mining per kW?
On gross revenue per kW, yes at current prices. But a GPU kW needs far more hardware money and only earns when rented, while an ASIC earns every hour it is on.
