The RDNA 2 iGPU used with AMD Ryzen 7000 CPUs has leaked its initial performance benchmarks, which indicate exceptionally good performance. The AMD Ryzen 7000 CPUs’ iGPUs will have two compute units, giving it a total of 128 stream processors. These cores will operate at a graphics frequency of 2200 MHz, which may be the max frequency, and a base clock speed of 400 MHz. This will give somewhat greater performance than the Nintendo Switch, which is listed at 500 GFLOPs, with up to 0.563 TFLOPs or 563 GFLOPs of computing capability.
This benchmark test was conducted with an AMD Ryzen 9 7950X CPU and 64 GB of DDR5 memory. It appears that the memory was running in a quad-DIMM configuration, which lowers the transfer rate to 3600 Mbps. As a result, we can anticipate slightly better performance from a tailored DDR5 kit operating at rates of between 5600 and 6400.
The “GFX1036” Device ID belongs to the AMD Ryzen 7000 iGPU, which achieved a score of 8210 on the Geekbench 5 OpenCL test.
For contrast, the same benchmark yields 7003 points for a Vega 6 GPU with 6 Compute Units built on the current 7nm architecture, while the Vega 8 GPU with 8 Compute Units can achieve 8000–8500 points. When compared to the Vega 8 integrated processor, AMD’s RDNA 2 iGPU’s final performance may be comparable, which would be impressive given that the Vega 8 chip has 75% more cores.
The graphics cores in that IO die are not many, the purpose of adding graphics is three-fold. One, it greatly expands these products in the commercial market where they don’t buy discrete at all, they just want to turn it on, have video encode/decode and light up some displays for office work and that’s what the GPU in the IO die will offer so that’s a huge business opportunity for us on the Ryzen PRO side as we start migrating these components over to that business.
The second is for diagnostic purposes, how do you know that you have a bad graphics card? Well, you have to swap in another graphics card but with the graphics core we have, you can do a little bit of troubleshooting thirdly, we were thinking about users who are planning to buy a discrete graphics, and it’s still in transit in the mail but all the other hardware has arrived first so it’s all sat there, looking at a pile of components and don’t have a GPU to actually set that all up. That would go away with the Ryzen 7000 series.
We are still going to do APUs with big graphics so APUs ‘BIG GRAPHICS’, CPUs ‘little graphics’. That would be our strategy going forward.

We are developing a lot of technologies that make use of integrated graphics in many ways and there are things that we are able to do with technologies such as Smart Shift ECO where we can turn off the discrete graphics and we can run the notebook off of the iGPU and say you want that because you want less heat, longer battery life (even when you are playing a game) or you want less fan noise or lower power consumption, there’s all these benefits to it. Because we have that thin integrated graphics in Ryzen 7000 series, it’s going to allow us to bring more of these types of smart technologies over to the desktops aswell so those customers can get some of these benefits.
Frank Azor (Chief Architect of Gaming Solutions)
These integrated GPUs are not designed to be excellent gamers, but rather to provide users with display output capabilities and an extra GPU when the need for debugging arises. Additionally, these wind up being fantastic choices for business and office PCs where it is not necessary to spend money on discrete GPUs.
