The RTX 4090 only just misses the 4 GHz limit by 70 MHz

The PC community is known for its ability to push hardware performance to ever new peaks. The days there was an impressive benchmark from a user called CENS on HWbot. CENS managed to overclock an Nvidia GeForce RTX 4090 GPU to an amazing 3,930 MHz. This graphics card, which is one of the absolute top models, already has a boost clock of 2,520 MHz and is known for its impressive high-speed performance.

After testing the Nvidia GeForce RTX 4090 when it launched in October 2022, people were so impressed with its performance that they dubbed it the “Queen of the Castle.” The brute performance of Nvidia’s Ada-Lovelace architecture makes it by far the fastest GPU on the market. Although it is already remarkably fast, users are still eager to test the GPU beyond its commercial limits.

To understand how CENS broke the 3,900 MHz barrier, it’s important to know what hardware he used for this record benchmark. CENS reports that he used a Z790 motherboard with an Intel Core i9-13900K processor from the Raptor Lake S architecture. Additionally, the system was equipped with 32 GB of DDR5-4300 RAM and cooled by liquid nitrogen cooling. The record is 46 seconds and 383 ms at a clock of 2.63 GHz to 3.93 GHz. This is the highest GPUPI benchmark recorded for the RTX 4090 at HWbot. GPUPI is not the most graphics-intensive benchmark, unlike 3DMark. Still, it’s an important achievement as it’s the first time a graphics card has come this close to 4 GHz.
