Server HopperGPU Description
The NVIDIA GB10 is an graphics card by NVIDIA, launched on an undisclosed date. Built on the 5 nm process and powered by the GB20B (standard variant) GPU, it supports DirectX 12 Ultimate, enabling modern gaming features such as hardware ray tracing and variable rate shading.
The GB20B has a die size of unknown die size with an unknown number of transistors transistors, featuring 6144 shaders, 384 TMUs, 48 ROPs, 384 tensor cores, and 48 ray tracing cores. It comes with 128 GB LPDDR5X memory on a 256-bit interface, running at 1067 MHz 8.5 Gbps effective.
The GPU operates at 1665 MHz, boosting up to 2418 MHz, with a maximum power draw of 140 W via no external power connectors. It connects through PCI Express, offers 1x HDMI, measures IGP, uses a system-specific cooling design, and launched at an undisclosed price.
