What just happened? While enthusiast-class discrete GPUs dominate discussions about high performance, integrated GPUs aren’t too far behind in terms of clock frequency overclocking records. The latest world record holder explained how he managed temperature and voltage levels to push an Intel iGPU beyond the 4GHz mark.
Pieter Massman, an overclocker, recently explained how he achieved a new record. Computex 2025: World record for graphics clock frequency . Massman beat the previous record holders by using an Intel Core Ultra 9 with integrated GPU. Massman
pushed the Arrow Lake processor Xe2-LPG64EU iGPU up to 4.25GHz with help from Asus’ Peter “Shamino” Tan. This is more than twice its stock boost clock. The team accomplished the feat twice. They validated the results in CPUZ during a Livestream at the Computex event this year in Taiwan.
According Massman’s Blog Taxes Bencheris a world record holder for both the integrated GPU clock rate and the GPU clock speed overall.
Since 2022 when the RTX-4090 was launched, frequency records have steadily climbed. From 3.3GHz in 2022 to 4.02GHz by 2023. Massman set the iGPU 3.9GHz record during an Arrow Lake launch late last year – using the same chip he later overclocked at Computex.
To overclock, Massman set the GT ratio to multiply default reference clock by 85, the highest setting available. Massman initially supplied 1.3V via a VccGT rail dedicated to the CPU graphics tile cores to the integrated GPU, but this only achieved 3.1GHz.
To push further, a delicate balance was required between overvolting and liquid-nitrogen cooling. Ultimately, 4.25GHz was achieved with 1.7V at a temperature of just -170degC.
However measuring the iGPU performance at these settings overwhelmed several benchmarking tools. Furmark crashed when it reached 2,800 points at 1080p. 3DMark Speed Way stopped around 650 points, and GPUPI 1B ran for only 17.9 seconds. To stabilize the system the team increased the reference clock and overclocked graphics die-todie interface.
While discrete GPU clock frequency records and overall GPU clock frequencies have steadily increased since the early 2000s; progress with iGPUs has only recently resumed.
After overcoming the 2GHz barrier in 2011 integrated GPU overclocking stagnated for nearly a ten-year period before surpassing 3GHz by 2023. It remains to be determined if graphics overclocking will plateau as CPU frequency gains did since 2010.
