The Nvidia RTX 40 graphics card does not support PCIe 5.0

According to reliable whistleblower Kopite7Kimi, NVIDIA RTX 40 series graphics cards will still support PCIe 4.0, not the latest PCIe 5.0. 

Intel's latest 12th-generation Core already supports PCIe 5.0, and some 600-series motherboards are also equipped with PCIe 5.0 Ready graphics slots, so many people think that the new generation of graphics cards will support this standard. However, the NVIDIA RTX 40 graphics card will support PCIe 4.0, probably because the ultra-high bandwidth of PCIe 5.0 is not needed for the time being.

As shown above, PCIe 5.0 x16 bandwidth will reach 128GB/s, doubling PCIe 4.0. Currently, consumer-grade products do not seem to use such high bandwidth. In March this year, NVIDIA's  Hopper GPU  architecture, the first GPU architecture to officially support PCIe Gen5, is suitable for data centers.

The first devices to use PCIe 5.0 on consumer products will be SSDs. During this year's CES, some manufacturers have announced the release plan of PCIe 5.0 SSD. Team Group Technology has released the CARDEA series PCIe Gen5 SSDs under its T-FORCE gaming brand. Its sequential read and write speeds are expected to be as high as 13000 / 12000MB / s  or more, and the storage capacity is as high as 4TB. It will be mass-produced in the third quarter.
