According to AMD’s previously announced plans, two APUs codenamed Dragon Range and Phoenix will come out in 2023 and belong to the Ryzen 7000 series. The Dragon Range is aimed at high-end, enthusiast-level gaming notebooks, while the Phoenix is used for thin and light gaming notebooks. Compared with the Ryzen 6000 series of the Zen 3+ architecture currently code-named Rembrandt, the number of CUs will continue to increase.
According to RedGamingTech, Dragon Range APU will be provided to users who need high CPU performance and basically do not consider integrated graphics. The GPU will only have two CUs. AMD will configure up to 16 cores, the corresponding model is Ryzen 9 7980HX, and there will be 12-core Ryzen 9 7900HX, 8-core Ryzen 7 7800HX, and 6-core Ryzen 5 7600HX. The chips have base frequencies between 3.6 GHz and 4 GHz, and boost frequencies between 4.8 GHz and 5GHz+.
The Phoenix APU will have fewer CPU cores than the Dragon Range, leaving more room for a powerful GPU, and rumors point to an upgrade to the RDNA 3 architecture. Since the performance of the GPU part has reached the level of some discrete graphics cards, and the performance of the CPU part has also reached the mainstream level, I believe it will become the choice of many mobile devices.
The Phoenix APUs are said to include the Ryzen 9 7980HS, Ryzen 9 7900HS, Ryzen 7 7800HS, and Ryzen 5 7600HS. In addition to the Ryzen 5 7600HS CPU with only 6 cores, several other APUs will be 8-core products. In addition, the GPU of Ryzen 5 7600HS is 6 CUs, and the rest of Ryzen 7/9 will have up to 12 CUs. The main difference between Ryzen 7 and Ryzen 9 is the frequency and TDP configuration.
It is reported that the floating-point performance of the Ryzen 9 7980HS will reach 9.2 TFLOPS, and the TDP will be between 60W and 70W, but the version with a TDP of 35W should also perform well. The rumored Phoenix APU has basically the same I/O capabilities as Rembrandt, except for the addition of support for the PCIe 5.0 standard. In addition, the Phoenix APU supports DDR5 and LPDDR5 memory.
There are also rumors that the AMD Phoenix APU will use a chiplet design, and a leaked block diagram shows that the Zen 4 architecture core and I/O parts are on one module, and the GPU is on another module.
