RDNA 3 graphics will soon be available on APUs.
According to Coelacanth’s Dream, an AMD engineer has posted a patch for Linux Kernel that enables support of integrated GPUs in the company’s upcoming Zen 4-based APUs, codenamed Dragon Range and Phoenix. Both processors may feature iGPUs based on the company’s RDNA 3 architecture, which hasn’t even entered the discrete GPU market.
The new patch enables the Zen 4-powered Dragon Range, the company’s next-generation Ryzen 7045-series APU designed for high-performance gaming laptops, according to Coelacanth’s Dream. The patch expressly states that it is intended for APUs and that it supports AMD’s SoC21 and GFX1103.
The Linux patch does not reveal how many RDNA 3 compute units and stream processors AMD intends to include in its Ryzen 7045-series “Dragon Range” APUs. However, given that we’re discussing processors with a 55W TDP, we’d expect them to deliver significantly greater performance than existing APUs with RDNA 2 graphics.
While we know that AMD’s Ryzen 7040-series Phoenix APUs are designed for more mainstream laptops (and are rumored to have a TDP between 35W and 45W), we do not know for certain whether it also employs RDNA 3. We certainly hope so, as it makes little sense for AMD to design two relatively mobile APUs with distinct graphics that will coexist on the market for a considerable amount of time.
As usual, AMD and other companies refuse to comment on unreleased products, so we will have to wait to learn more about the Dragon Range and Phoenix APUs. Perhaps we’ll learn more at CES early the following year.
