ASUS GeForce RTX 4090 reaches 4005 MHz OC
Within a few hours of Cens achieving a clock speed of 3975 MHz using RTX 4090 from Colorful, another enthusiast and overclocker, Splave, has successfully surpassed the legendary 4000 MHz threshold.
For this result, Splave used the ASUS RTX 4090 ROG Matrix GPU, which has not yet been released to the public. This is a highly binned model with a powerful liquid cooler, but overclockers do not rely on such basic techniques. Instead, liquid nitrogen combined with lots of patience and experience is used.
The RTX 4090 has been overclocked to 4005 MHz with GPUPI benchmark with GPU temperature reading -34.6°C. As mentioned many times before, this benchmark has hardly anything to do with modern 3D graphics, but it does use the GPU to calculate the number pi. Such a light workload allows the processor to clock higher, which is why we only see world records featuring this benchmark, not 3Dmark or anything alike.
The RTX 4090 at this clock speeds requires more than 1000 watts, but the exact value for these results was not shared. In order to break 3.975 GHz, Colorful iGame GPU required 1.1 KW.
It is worth reminding that the 3.0 GHz barrier was broken almost 3 years ago by TecLab using RTX 2080 Ti Turing graphics card. The following series based on Ampere architecture gave a substantial frequency boost, but clocks reaching 4.0 GHz were not possible. Only with the release of RTX 40 series with Ada architecture such clocks were finally in sight, but it took more than 8 months since RTX 4090 was released to finally get to this point.
