The overclocker has achieved a high performance gain by overclocking the integrated RDNA2 graphics chip in the AMD Zen 4 processorAs computer hardware enthusiasts, we like to check how much more can be squeezed out of silicon chips, even if it is to be art for art’s sake. At the outset, it is worth noting that the AMD 7000 series processors have a small iGPU, because they are only two blocks that are really only supposed to display the image for basic activities. However, this did not prevent the overclocker, known as Skatterbencher, from overclocking the integrated graphics card.

Skatterbencher found a way to overclock the integrated graphics card in AMD Ryzen 7900 processors. It achieved an average performance increase of up to 30% with a small increase in power consumption.

The enthusiast used two programs: AMD Precision Boost Overdrive and GFX Curve Optimizer. Thanks to them, he was able to overclock the graphics chip and increase the voltages on the iGPU. The basic settings of the integrated graphics card are: a clock frequency of 2.2 GHz at a voltage of about 0.997 V and a memory clock speed of 2.4 GHz. It is also worth noting that with default settings, the I/O chiplet with the iGPU consumed about 38.5 W. Thanks to manual overclocking, it was able to overclock the graphics chip to 2949 MHz at 1.2 V and 3.2 GHz on the cache. This translated into a chiplet power consumption of up to 63.5 W.

In the next steps by adjusting the voltage curve to the frequency of the GFX, the GPU clock increased to 3.1 GHz at 1.395 V, although the SOC reported a consumption of 60.7 W, which is slightly lower than previously. The memory timing, however, remained at the same level as before, and the system temperature reached 52.8 ° C. These actions translated into an average performance increase of 30%, and in Tomb Raider up to 41.67%. Despite this, the integrated graphics chip was still not suitable for playing video games, as the frame rate increase in Lara Croft’s adventures reached 5 fps. Excluding CS:GO, where the increase reached about 21 frames per second, providing us with a smooth image around 80 fps.The overclocker has achieved a high performance gain by overclocking the integrated RDNA2 graphics chip in the AMD Zen 4 processor [3]
