It looks like GeForce RTX 40 graphics cards will not support the latest PCIe 5.0 standard. This was reported by kopite7kimi, a well-known insider in the field.
He has previously been the first to reveal the specs of future 3D cards many times, so his information can often be believed.
For what reason Nvidia decided not to add support for the new generation of adapters, it is not clear. But it is worth recalling that the upcoming Ryzen 7000 processors will support PCIe 5.0, and Intel’s desktop platform has such support already now.
The source also noted that it never disclosed details regarding the SM blocks of the GA102 graphics core, so don’t assume in advance that the GPU will necessarily have 18,432 FP32 blocks, which we are used to calling CUDA. This suggests that in the new architecture, Nvidia may again reconsider the internal structure of GPU computing blocks.
