Ryzen 7000 series desktop processor’s iGPU overclocked to 3100MHz
An obvious change of the Ryzen 7000 series desktop processors compared to the Ryzen 5000 series desktop processors is the integrated graphics. Although the specifications are obviously not as good as the integrated graphics of previous APUs, there is still no problem with turning on the machine and watching videos. The iGPU adopts the RDNA 2 architecture and has two CUs, a total of 128 stream processors, a base clock of 400MHz, and a boost clock of 2200MHz. Naturally, you can’t have too many expectations in terms of game performance. Recently, SkatterBencher conducted an overclocking test on the iGPU.
SkatterBencher first tested the performance of the iGPU in the default state, and the 3DMark Night Raid score was 11162 points. The average frame rate in the “Shadow of the Tomb Raider” benchmark is 12, and the average frame rate in the “CS: GO” FPS Bench is 57.87. When the iGPU runs the Furmark graphics card stress test, the GPU clock is 2200MHz and the voltage is 0.997V.
SkatterBencher first turned on the PBO 2 and EXPO functions. At this time, the memory clock has reached 6400MHz, and the iGPU clock has not changed. The performance improvement brought about by the increase in memory bandwidth is limited, and the performance improvement of most items in the test does not exceed 5%.
Then SkatterBencher performed manual overclocking. When the clock of the iGPU is adjusted, the motherboard will automatically adjust the voltage. When the motherboard used by SkatterBencher exceeds 2600Mhz, the voltage will remain at 1.25V. After testing, the iGPU can run stably at 2975MHz. The performance improvement brought about by frequency increase is also very obvious, most of the test items have more than 25% improvement.
Finally, SkatterBencher increased the iGPU voltage to 1.4V through the GFX Curve Optimizer function, and the clock also reached 3100MHz. Compared with the clock of 2975MHz, the test results are further improved.
