An analysis by Moores Law is Dead (via HardwareTimes) suggests that AMD's next-generation RTX 7000 series (which have been confirmed to be based on the MCM approach) could out-perform NVIDIA's RTX 4000 series GPUs. It goes without saying that this is a huge rumor and should be taken with buckets of salt till further verification is received. That said, this is an inference by MLiD based on information provided by his sources (and corroborated by at least one independent leak given below) and if those are considered to be credible enough - then this inference could very well turn out to be true as well.

A quick recap for our readers before we dig into this. A leaked LinkedIn description of an AMD Principal Member of Technical Staff more or less confirmed that the upcoming RX 7000 series is based on RDNA3 and has at least 1 SKU with two different processes involved (TSMC 5nm and 6nm). The only reason this would be the case is, of course, if AMD was going with an MCM approach as far as its GPUs go.
