The next generation of graphics cards would ultimately not use PCI Express 5.0. A logical choice given the limited support for this technology.
The months go by and the next generation of Nvidia graphics cards is approaching. No more Ampere, the GeForce RTX 4000 will use the new Ada Lovelace architecture dedicated to the general public and more specifically to video games. This new generation promises to break new power records and quickly make us forget the GeForce RTX 3000s that have been so hard to find for many months.
The period is conducive to rumors and leaks. The latest concerns the transfer and power protocol used by Nvidia.
PCI Express 4.0 is too important
According to the account Kopite7kimi, rather famous when it comes to the next Nvidia products, the GeForce RTX 4000 should continue to use PCI Express 4.0. Since the launch of Alder Lake processors (12th generation Intel Core), Intel has managed the brand new PCI Express 5.0 on its platform. This new interface promises up to 128 GB / s of bandwidth against 64 GB / s for PCI Express 4.0. This is what Nvidia had highlighted by unveiling Hopper, its first PCI Express 5.0 compatible GPU for professionals.
Unfortunately, PCI Express 5.0 is not yet supported by AMD’s platform. This should be the case by the end of the year with the arrival of the Ryzen 7000 and the AM5 platform, but we can assume that the level of adoption will be far too low.
We can still reasonably imagine that the next GeForce RTX 4000 will support the ATX 3.0 / PCI Express 5.0 power interface. This is a new 16 pin connector that allows the graphics card to receive up to 600W from the PC power supply. If we believe the leaks around the RTX 4090, it will need it.
