The AMD Phoenix APU will combine Zen 4 CPUs and RDNA 3 GPUs

In a recent leak, the existence of the Phoenix APU was discovered, which will consist of CPU cores based on the Zen 4 architecture accompanied by an integrated RDNA 3 GPU. In particular, according to the Compubase colleagues, citing various unofficial sources, the GPU could be constituted with up to 16 compute units, for a total of 1,536 Stream Processors (for comparison, the current APUs stop at 512 SP ) and performance similar to a Radeon RX 6500 XT or RX 6600 XT. Phoenix APUs will support DDR5 and LPDDR5 memory, providing more bandwidth than currently on the market, as well as, presumably, the PCI Express 5.0 interface.



At the moment, we do not know which node will be used for its production, as the Zen 4 cores are designed for TSMC's N5, while the RDNA 3 GPUs should employ N5 and / or N6. It is possible that AMD decides to use a tile design for its APUs, but at the moment it is only pure speculation. After several years of APUs equipped with integrated Radeon RX Vega class GPUs, finally with the recent Ryzen 6000 series "Rembrandt" the Sunnyvale company has decided to equip the chips with GPUs based on the RDNA 2 architecture, providing significantly better performance both for everyday workloads as well as for gaming.


A few days ago, we told you that the AM5 socket, which should arrive by the end of the year to host future Ryzen 7000 CPUs, could only be compatible with DDR5 RAM memories. If this is confirmed, it could be a disadvantage for AMD, especially given the current shortage of power management integrated circuits (PMICs) and VRMs, indispensable components for RAM, which has caused less than exceptional availability so far, as well as to an increase in costs.
