As part of today’s burst of ISC 2021 trade show announcements, NVIDIA this morning is announcing that they’re bringing the 80GB version of their A100 accelerator to the PCIe form factor. First announced in NVIDIA’s custom SXM form factor last fall, the 80GB version of the A100 was introduced to not only expand the total memory capacity of an A100 accelerator – doubling it from 40GB to 80GB – but it also offered a rare mid-generation spec bump as well, cranking up the memory clockspeeds by a further 33%. Now, after a bit over 6 months, NVIDIA is releasing a PCIe version of the accelerator for customers who need discrete add-in cards.
The new 80GB version of the PCIe A100 joins the existing 40GB version, and NVIDIA will continue selling both versions of the card. On the whole, this is a pretty straightforward transfer of the 80GB A100 over to PCIe, with NVIDIA dialing down the TDP of the card and the number of exposed NVLinks to match the capabilities of the form factor. The release of the 80GB PCIe card is designed to give NVIDIA’s traditional PCIe form factor customers a second, higher-performing accelerator option, particularly for those users who need more than 40GB of GPU memory.
