AMD platform has full support PCIe 4.0, from consumer level to data center, graphics card, processor, motherboard chipset all have. While Intel initially declined verbally, the body was also honest, in addition to being supported in areas such as FPGA PCIe 4.0, second-generation hauteng storage, future consumer-level platforms will also be imported.On the NVIDIA hand, Huang Renxun just unveiled a new generation of "amperage "(Ampere) architecture, focusing on AI、 data centers, high-performance computing and other market areas, but also introduced PCIe 4.0. for the first time
For the support PCIe 4.0, Huang Renxun did not mention in the speech, the official information is also very low-key,Only the words "PCIe 4.0 main control interface" are marked on the architecture diagram of ampere, and the PCIe 4.064gb/s is listed in the specification table of Tesla A100 calculation card.
The PCIe 4.0,Tesla A100 card also supports the third generation NVLink interconnection bus, each GPU up to 12 channels, bandwidth up to 600 GB/s, compared to the second generation is 6,300, the first generation only 4,160 GB/s..
Whether the future RTX 30 series of game cards also support PCIe 4.0, there is no exact news, but there is no reason not to support.
