AMD Ryzen 7000 Integrated RDNA2 GPU overclocked to 3.1 GHz, up to 42% Performance Increase

Skatterbencher, who is famous for pushing the limits of overclocking, examines AMD’s desktop CPU. In his recent review, the emphasis was on the optimization of the integrated graphics performance. It is important to note that the Ryzen 7000 desktop series comes with a small RDNA2 GPU component that has only 2 Compute Units. This is not sufficient to provide an optimal gaming experience, but it doesn’t stop individuals from attempting to do so.

Skatterbencher experiments with different overclocking techniques to unleash the processor’s full potential, which includes utilizing AMD Precision Boost Overdrive and GFX Curve Optimizer. By using both methods combined, it is possible to achieve higher voltages and unlock the processor’s maximum performance capabilities.

At the stock configuration, the iGPU runs at a clock speed of 2.2 GHz with a voltage of approximately 0.997 volts while running the Furmark software. Equally significant is the memory clock, which is set at 2.4 GHz. At this setting, the CPU’s GPU and SOC (a separate die on the package) use approximately 38.5 watts of power. However, through manual overclocking, Skatterbencher was able to increase the iGPU clock speed to 2949 MHz with a voltage of 1.2V, which increased power consumption to 63.5 watts. Additionally, the memory clock was adjusted to 3.2 GHz.

After tweaking the GFX voltage/frequency curvature even further, the GPU clock speed increased to 3.1 GHz with a voltage of 1.395 volts. As a result, the temperature rose to 52.8°C from the stock temperature of 38.4°C. The SOC power was reported to be around 60.7 watts, which is slightly lower than before.

SkatterBencher observed a performance improvement of up to 41.67% depending on the workload, for instance, in a game like Tomb Raider at 1080p resolution. However, the game is still not enjoyable with the increased performance. It is worth noting that with the iGPU overclocking, SkatterBencher was finally able to run the raytracing benchmark, which was previously impossible with the stock settings.

The reviewer concludes that the overclocking experience of integrated RDNA2 graphics is much better than the experience with discrete models. AMD’s Dragon Range mobile CPUs will also include such an iGPU, but it’s likely to be more challenging to overclock than the desktop versions.
