GPU Description

The NVIDIA B300 is an graphics card by NVIDIA, launched on an undisclosed date. Built on the 5 nm process and powered by the GB110 (standard variant) GPU, it supports DirectX 12 Ultimate, enabling modern gaming features such as hardware ray tracing and variable rate shading. The GB110 has a die size of unknown die size with 104,000 million transistors, featuring 18944 shaders, 592 TMUs, 24 ROPs, 592 tensor cores, and unknown ray tracing cores ray tracing cores. It comes with 144 GB HBM3e memory on a 4096-bit interface, running at 2000 MHz 8 Gbps effective. The GPU operates at 1665 MHz, boosting up to 2032 MHz, with a maximum power draw of 1400 W via no external power connectors. It connects through PCI Express, offers No outputs, measures SXM Module, uses a system-specific cooling design, and launched at an undisclosed price.
