Performance Rating

The GB10 is an enthusiast-class professional graphics card by NVIDIA, launched on October 15th, 2025. Built on the 5 nm process, and based on the GB20B graphics processor, the card does not support DirectX. Since GB10 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. It features 6144 shading units, 384 texture mapping units, and 48 ROPs. Also included are 384 tensor cores which help improve the speed of machine learning applications. The card also has 48 raytracing acceleration cores. NVIDIA has paired 128 GB LPDDR5X memory with the GB10, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1665 MHz, which can be boosted up to 2418 MHz, memory is running at 1067 MHz.
