AMD Planning September Launch for Radeon RX 7800 series and RX 7700 series
AMD is planning to plug the Atlantic gap between its mainstream Radeon RX 7600 and enthusiast-class RX 7900 XT with the RX 7800 series and RX 7700 series, with either an announcement or teaser planned for 2023 Gamescom, which is scheduled for August. There could be up to four new graphics card SKUs announced, with their product launches spread across Q3 and Q4 2023. The "Navi 32" MCM is expected to power at least three of these SKUs, while it was recently rumored that AMD could design a new GPU that has the GCD of the "Navi 31" on the package of "Navi 32" with its four MCDs, to end up with a higher CU count than what the "Navi 32" can offer.
The "Navi 32" GPU is an MCM, just like the "Navi 31" powering the RX 7900 series. It is rumored to feature a 5 nm GCD (graphics compute die) with 60 RDNA3 compute units, which work out to 3,840 stream processors, 120 AI accelerators, 60 Ray Accelerators, 240 TMUs, and possibly 128 ROPs. The four 6 nm MCDs give it 64 MB of Infinity Cache, and a 256-bit wide GDDR6 memory interface. Assuming the RX 7800 XT uses the unnamed new MCM with the GCD of the "Navi 31" that has a CU count somewhere between 60 and 72, a maxed-out "Navi 32" could power the RX 7800, while its cut-down variants power the RX 7700 XT and RX 7700.
