Nvidia Ampere Pcie 4

Nvidia has revealed the first pci express variant of the ampere a100 gpu that it unveiled last month but gamers shouldn t get excited.

Nvidia ampere pcie 4. The a100 gpu supports pci express gen 4 pcie gen 4 which doubles the bandwidth of pcie 3 0 3 1 by providing 31 5 gb sec vs. Nvidia didn t announce this for its dgx a100 system but supermicro also revealed new systems powered by the ampere a100 gpu and that announcement confirms that the. Pcie gen 4 with sr iov. The faster speed is especially beneficial for a100 gpus connecting to pcie 4 0 capable cpus and to support fast network interfaces such as 200 gbit sec infiniband.

Nvidia ampere the next gen graphics architecture from nvidia will supposedly have pcie 4 0 support. 15 75 gb sec for x16 connections. In a thread on the nvidia subreddit an engineer confirmed that no you won t need pcie 4 0 for the 3090. While the ampere gpus are yet to be announced nvidia did recently tease the hgx a100 platform.

So where pcie 4 0 will be helpful is in setups like mine where i have a second card optane that forces a split of 16x slot into 8x 8x. 2080ti is right over the bandwidth of pcie 3 0 8x bandwidth. It s designed to accelerate development in the fields of. Nvidia ampere architecture based gpus support pci express gen 4 0 pcie gen 4 0 which provides 2x the bandwidth of pcie gen 3 0.

This improves data transfer speeds from cpu memory for data intensive tasks such as ai and data science. While a 16x 4 0 slot has higher bandwidth the card will perform almost exactly as well. Nvidia says this leads to a 10 performance penalty in single gpu workloads. The first pcie 4 0 servers based on intel s 10nm ice lake sp xeon cpus nvidia s 7nm ampere a100 gpus have been unveiled by inspur.

Intel s upcoming 11th generation rocket lake cpus and nvidia s upcoming gpus based on ampere architecture will support pcie 4 0 standard. With pcie 4 0 8x you won t hinder the card where as pcie 3 0 8x would hinder a 3080ti and likely other cards in the lineup.
