AMD Ryzen 7000 “RDNA 2” iGPU Overclocked To 3.1 GHz, Delivers Up To 42% Performance Improvement

wccftech.com:

AMD's RDNA 2 iGPU featured on the Ryzen 7000 CPUs, has been overclocked to an impressive 3.1 GHz frequency.

The iGPU on the AMD Ryzen 7000 CPUs does feature the RDNA 2 graphics architecture but it is by no means meant to be used as a gaming GPU. The main purpose of having this chip is to assist PC users with the diagnostic but it can be overclocked like any other part of the Ryzen 7000 CPUs and Skatterbencher has shown what this chip is capable of.

While the AMD Radeon 680M "RDNA 2" iGPU produces very playable frame rates in modern titles, it also features 6 times more compute units (12 vs 2). The 2 Compute Units on the Ryzen 7000 series are going to be enough to power office PCs & do lightweight graphics tasks while supporting new encode/decode technologies. So in terms of specifications, the Radeon iGPU packs 2 CUs running at a maximum frequency of 2200 MHz.

Skatterbencher used the AMD Ryzen 9 7900 on a Gigabyte B650E AORUS Tachyon motherboard to test the RDNA 2 iGPU. At its default clocks, the iGPU delivered around 12 FPS in Tomb Raider & 58 FPS on average within CS: GO at 1080p. By enabling EXPO, the performance increased by up to 12% which shows that there's a memory bandwidth bottleneck. While this didn't improve the gaming performance by a whole lot, it shows that more performance can be squeezed out of the RDNA 2 iGPU.

The last overclocking method used was to utilize the graphics curve optimizer. This method allowed the overclocker to push the Radeon "RDNA 2" iGPU to 3100 MHz or 3.1 GHz. That's an overclock of +900 MHz which is huge for an integrated chip. The results also speak for themselves, the 40% OC resulted in a +42% increase in
