Overclocked AMD Radeon 780M iGPU on Ryzen 7 8700G gains up to 61.14% performance boost

AMD Radeon 780M has always stood out as a very capable integrated graphics solution. In our benchmarks of mobile devices that featured the iGPU, we found that its overall performance is better than the Nvidia GTX 1650 Max-Q, which is a dedicated GPU. However, it seems that the integrated GPU couldn’t reach its full potential on mobile devices.

For those wondering, before the AMD Ryzen 8000G series launch, the Radeon 780M integrated GPU was only available on mobile devices. On these, it’s not really possible to push the iGPU much, as mobile cooling solutions aren’t as robust as the custom ones overclockers employ for extreme OC.

But now that the AMD Ryzen 8000G lineup with the 780M is officially out for desktops, we finally got to see how much the iGPU can be overclocked. SkatterBencher is among the first overclockers to shed light on this.

The overclocker first benchmarked the Ryzen 8700G APU (available on Amazon) with stock settings to get a baseline. In the stock configuration, the Radeon 780M integrated GPU reached 2881 MHz and had a peak power of 49.8W.

Then, SkatterBencher enabled XMP and Precision Boost 2 (PBO 2) modes on the Ryzen 8700G. This made the clock speed max out at 2903 MHz with 68.5W of peak GPU ASIC power. It offered a performance boost of 26.3%.

Next, SkatterBencher manually tweaked the PBO 2 to get a higher chip voltage. The overclocker saw a 3053 MHz peak GPU clock with 159W of max power consumption in the OCCT stress test. This led to up to a 28.9% performance uplift from the Radeon 780M iGPU stock settings.

After manually overclocking the chip and adjusting the GFXCLK, MCLX, FCLK, and UCLK, the iGPU of Ryzen 8700G reached 3086 MHz and peaked at 155.6W in the OCCT stress test. This method offered up to a 39.09% performance boost.

But the largest gain that SkatterBencher saw was in the fifth overclock. The overclocker set the DDR5 memory modules to 7800 MT/s, adjusted the timings, and changed the settings of both the CPU and iGPU. This OC allowed the Radeon 780M of the APU to offer up to a 61.4% performance gain with an average of 37.75% boost over stock.

However, SkatterBencher noted that the last config isn’t stable and leads to artifacts, so the overclocker didn’t perform any stress test for this overclock. You can learn more about how to do these overclocks and gain more insight into each one from the video attached below.
