AMD is planning to launch its next-gen Zen 4 APU lineup in the form of Phoenix next year. Optimized for light-eight and ultrathin notebooks, these processors will pack up to eight 5nm Zen 4 cores, sixteen threads, and a cutting-edge RDNA 3 integrated GPU. The latter will feature as many as 6 Work Group Processors (WGPs) or 12 Compute Units (CUs) for a total of 1,536 stream processors (cores). Note that the RDNA 3 graphics architecture doubles the width of the CUs and the WGPs from 64 to 128 and 128 to 256, respectively.
Courtesy of TSMC’s 5nm node, the boost clocks should approach the 3GHz mark, and since AMD has already promised a 50% gain in performance per watt, it shouldn’t be hard. Like the Radeon 680M, the iGPU won’t pack any Infinity Cache but the L2 should see a healthy increase. Pair that with dual-channel DDR5/LPDDR5 memory, 128-bit memory bus, and enhanced color compression; the GPU should be well-fed.

Overall, the Phoenix-class Ryzen 7000 mobile processors should be 60-80% faster than the 6000 series (Rembrandt). AMD might even go as far as to claim that the top-end Ryzen 7000 processors offer RTX 3060-level gaming performance with FSR 2.0 turned on. Keep in mind that these will likely be power-starved models with FSR/DLSS disabled. However, the RTX 3050 might very well get murdered by the Phoenix iGPU.
According to Tom, Phoenix won’t be available in budget notebooks which makes me wonder if AMD is planning yet another Zen 3 refresh for the entry-level market, or simply a smaller Zen 4 + RDNA 2 die. Lastly, the Radeon RX 6000 desktop GPUs will be launching in the fourth quarter of the year, probably October as already reported by other sources.
