AMD Raphael: Zen 4 CPU with integrated RDNA 2 GPU in action

A benchmark entry confirms the already suspected key data of upcoming Zen 4 desktop solutions with the code name Raphael. The RDNA 2 GPU is also included, the benchmark tool recognizes this as a Rembrandt solution, which is the most obvious variant given the same architecture of this GPU unit.

Much of the leaked information aligns with recent rumors and official statements AMD made earlier this year. In January, the manufacturer emphasized that the Zen 4 consistently works at over 5 GHz in gaming tests. The fact that a benchmark reads 5.2 GHz is therefore no coincidence, but fits into the picture. The CPU ID is also not unknown, it also appeared in another benchmark database in January.

New iGPU is here for the first time

But not only are the Zen 4 cores at high clocks the big innovation of the Raphael desktop processors, but also the graphics unit integrated for the first time. But that doesn't make Raphael an APU, the GPU is far too small for that. Only 2 to 4 CUs are currently suspected. But that should be enough for additional display options and certain functions of a media de- and encoder – Intel's integrated GPU in the Alder Lake desktop processors is ultimately of little use for much more. AMD thus closes a gap so that from now on every AMD CPU can be operated without an additional GPU, albeit only for rudimentary things related to graphics.

Ultimately, it is obvious that the GPU including audio (e.g. via HDMI) is recognized as a Rembrandt variant. RDNA 2 as a graphics IP is in all current custom SoCs such as the console chips, but also AMD's own Rembrandt APU aka AMD Ryzen 6000. The most obvious support in desktops and notebooks can therefore be found right here.

The first result of the GPU is not very outstanding: The benchmark from ET: Quake Wars delivers 63.1 FPS, while an AMD Ryzen 9 6900HX as a real Rembrandt delivers over 182 FPS. But as I said: Fewer CUs and probably significantly less clock play a role here. Rather, it should be taken away from the first tests that the solution works.

Start in autumn, teaser in two weeks?

< p class="p text-width">AMD will officially unveil the Zen 4 processors for the desktop in the fall. At Computex in two weeks, traditionally the trade fair for the classic PC environment, AMD's boss Lisa Su shouldn't miss the opportunity to spread further teasers in this direction.
