AMD Zen 4 architecture APU may use RDNA 3 architecture GPU
Recently, Coelacanth-Dream discovered that AMD’s Linux software engineers released the latest Linux patches to support the iGPU of Zen 4 architecture APUs, code-named Dragon Range, and Phoenix products, and the iGPU is likely to adopt the latest RDNA 3 architecture.
Dragon Range is for high-end and enthusiast gaming notebooks, and Phoenix is for thin and light gaming notebooks. Compared with the current Ryzen 6000 series codenamed Rembrandt’s Zen 3+ architecture, it will obviously have stronger performance. The patch does not specify how many CUs the new APU’s core will have. It is rumored that AMD may increase the number of CUs.
It has been reported that Dragon Range will have up to 16 cores for users who need high CPU performance and basically do not consider integrated graphics. The GPU will only have two CUs. The Phoenix will be configured with up to 8 cores, leaving more space for a powerful GPU, and its performance can reach the level of some discrete graphics cards. The TDP of the Phoenix APU is between 35W and 45W. Some netizens once revealed that its graphics performance is about equal to the 60W GeForce RTX 3060 mobile GPU, which is the version previously known as Max-Q.
The Phoenix APU may also use a small chip design, with the Zen 4 architecture core and I/O part on one module, the GPU on another module, and support for DDR5 and LPDDR5 memory. In addition, the RDNA 3 architecture core used by the APU does not have Infinity Cache.
