NVIDIA A100 Ampere GPU Launched in PCIe Form Factor, 20 Times Faster Than Volta at 250W & 40 GB HBM2 Memory

NVIDIA has added a third variant to its growing Ampere A100 GPU family, the A100 PCIe which is PCIe 4.0 compliant and comes in the standard full-length, full height form factor compared to the mezzanine board we got to see earlier.

NVIDIA’s A100 Ampere GPU Gets PCIe 4.0 Ready Form Factor – Same GPU Configuration But at 250W, Up To 90% Performance of the Full 400W A100 GPU

Just like the Pascal P100 and Volta V100 before it, the Ampere A100 GPU was bound to get a PCIe variant sooner or later. Now NVIDIA has announced that its A100 PCIe GPU accelerator is available for a diverse set of use cases with system ranging from a single A100 PCIe GPU to servers utilizing two cards at the same time through the 12 NVLINK channels that deliver 600 GB/s of interconnect bandwidth.

In terms of specifications, the A100 PCIe GPU accelerator doesn’t change much in terms of core configuration. The GA100 GPU retains the specifications we got to see on the 400W variant with 6912 CUDA cores arranged in 108 SM units, 432 Tensor Cores and 40 GB of HBM2 memory that delivers the same memory bandwidth of 1.55 TB/s (rounded off to 1.6 TB/s). The main difference can be seen in the TDP which is rated at 250W for the PCIe variant whereas the standard variant comes with a 400W TDP.

Now we can guess that the card would feature lower clocks to compensate for the less TDP input but NVIDIA has provided the peak compute numbers and those remain unaffected for the PCIe variant. The FP64 performance is still rated at 9.7/19.5 TFLOPs, FP32 performance is rated at 19.5 /156/312 TFLOPs (Sparsity), FP16 performance is rated at 312/624 TFLOPs (Sparsity) & INT8 is rated at 624/1248 TOPs (Sparsity).
