Objectively speaking, for RTX40 series graphics cards, in addition to expecting a significant increase in performance and the best price not to rise, many people also hope that it can bring some new technical support, such as PCIe 5.0, DP 2.0 interface, etc.
Technically, PCIe 5.0 has a bandwidth of up to 128GB/s, twice as much as PCIe 4.0. The Hopper GPU that has been released supports PCIe 5.0, so it is reasonable to upgrade the RTX40 series graphics card in this technical detail.
However, the latest news given by a whistleblower poured a basin of cold water, he pointed out that RTX 40 did not have PCIe 5.0, still continue PCIe 4.0. The reason why PCIe 5.0 is popular is that it will take the lead in using the Intel ATX 3.0/PCIe 5.0 standard 16-pin external power supply, that is, a single wire can carry 600W.
Of course, from a realistic point of view, even the RTX 30 series graphics card, under PCIe 3.0 and 4.0 performance is almost no difference, that is, the graphics card does not use so much theoretical bandwidth. This may explain why RTX 40 eventually abandoned PCIe 5.0.
