Ryzen 7000 rumors start flying as "Phoenix" is revealed as AMD's likely Zen 4 successor to Rembrandt

A simple tweet from a software engineer has led to a whole flock of rumors about what could be AMD’s Ryzen 7000 mobile APU series. Patrick Schur also mentioned Raphael in the relevant post, which we have reported on before. Raphael will supposedly be the desktop successor to Warhol, which is itself the successor to the current Ryzen 5000 Vermeer family, and it will be based on the AM5 microprocessor socket. Schur also mentioned Phoenix, which if it really is AMD’s Zen 4/5nm Ryzen 7000 mobile APU, will already be a departure as Team Red goes with mythical creatures (or US state capitals?) for processor family codenames rather than famous painters. There is a George Phoenix, a British artist noted for his portraits, but he’s not on the same familiarity level with the general public as Picasso or Van Gogh.

The post reveals that Phoenix, which has been vaguely hinted at before in an alleged roadmap that simply stated “P******” for the future of AMD’s mobile parts, has the CPUID A70F00 and more tellingly will use the FP8 socket. This shows that Phoenix is a mobile processor, as the current Cezanne Ryzen 5000 mobile APUs utilize FP6. This is where a lot of rumors start flying, such as Rembrandt, the Ryzen 6000 mobile APU family based on Zen3+ microarchitecture, being the only chip series to use an FP7 socket. Furthermore, it’s also expected that Phoenix will offer DDR5 support, which is also supposedly coming with Rembrandt anyway, and that it will use the 5nm manufacturing process. There is a table below showing the rumored differences between generations.

The rumors about Ryzen 7000 Phoenix don’t stop there. It has also been suggested that PCIe 5 support could also be included, although it has been speculated it will be initially limited with how many lanes can be used. More processing cores may also be on board, with VideoCardz stating that up to 12 cores could feature on Phoenix APUs. As for the iGPU architecture, while Cezanne Ryzen 5000 uses Vega, the above-mentioned roadmap has claimed that AMD will go with RDNA2 (Navi) for Rembrandt Ryzen 6000, and it seems likely that Ryzen 7000 would also feature RDNA2 graphics technology with some additional tweaking. As for a Phoenix release timeframe, we could see it rise from the ashes by the first quarter of 2023, so we still have a whole two years full of rumors, leaks, and confirmations to help build up an accurate picture of what will be Zen 4 mobile.
