The launch of NVIDIA’s next-generation GeForce RTX 40 series graphics cards, powered by its Ada Lovelace architecture, is expected to happen later this year. However, a recent rumour online is now suggesting that its top-tier GPU, the AD102, will be lacking PCIe Gen5 support.
The rumours come from the reliable and prominent leakster, Kopite7kime (@kopite7kimi), who supposedly “confirmed” that NVIDIA’s future GPU will be sticking to the current PCIe Gen4 interface, and not transitioning towards PCIe Gen5. Suffice to say, the news is a bit surprising, considering that all the news about the GPU has, thus far, led us to believe that NVIDIA would actually support the PCIe Gen5 interface.

One physical indication of its supposed shift from PCIe Gen4 to Gen5 could technically be seen in all of the current GeForce RTX 3090 Ti cards; the PCIe power connector installed on them a microFit MOLEX, 16-pin PCIe Gen5 connectors, capable of supporting up to 600W through a single connector.
Again, this is all just a rumour, even if kopite7kime says that they’ve more or less confirmed it. Further, if this really were the case, then NVIDIA would simply be shooting itself in the foot, especially since retaining PCIe Gen4 over Gen5 would clearly translate into some serious performance bottleneck issues. On that note, it would be best to wait for an official announcement from NVIDIA on the matter.
