AMD Ryzen 7000: Raphael GPU should only have 128 RDNA2 shaders

With the Ryzen 7000 processors, codename Raphael, AMD wants to launch a new CPU generation by the end of the year. As was confirmed at Computex, the new CPUs will be based on the new AM5 socket, the Zen 4 architecture and TSMC’s 5 nm production for the first time. As a result, AMD wants to offer significantly increased computing power and also a revised platform with which the company supports DDR5 RAM and PCI Express 5.0 for the first time.

With Ryzen 7000 there should not only be innovations on the processor and on the platform. Instead, AMD also confirmed at the trade fair that a GPU should be installed throughout the new generation for the first time, which would catch up with Intel here. In the successors to the current APUs, the GPU should continue to be housed in a monolithic chip together with the CPU. For Raphael, where two CPU chiplets are usually installed, the new GPU should be accommodated in the additional IO chip.

Unfortunately, AMD has not revealed any details about the performance so far. All that is known is that it is said to be an RDNA2 GPU and that the entire chip is manufactured in the 6 nm process. The website Angronomics but now claims that it also knows the planned expansion stage of the GPU. According to this, the built-in graphics unit should have the code name “Coral Bandfish” and have a workgroup processor (WGP). Such a unit in RDNA2 contains two compute units, which means that Ryzen 7000 would have 128 shaders.

“Right now, Angstronomics can reveal that the Raphael’s onboard graphics, GFX1036, codenamed Coral Bandfish, includes an RDNA2 WGP.”

This would make the Raphael GPU significantly slower than the current APU generation: The Ryzen 5 5600G comes with at least 448 shaders on the desktop, and even in notebooks, no APUs with fewer than 384 shaders are currently sold. The IGP of the Ryzen 7000 CPUs will therefore probably only be suitable for very simple graphics applications and the playback of the codecs supported in hardware. On the other hand, the corresponding APU generation, in which AMD will probably install significantly more shaders, should provide more graphics performance.
