GPU Description

The AMD Radeon Instinct MI355X is an graphics card by AMD, launched on an undisclosed date. Built on the 3 nm process and powered by the Galaxy (standard variant) GPU, it supports DirectX 12 Ultimate, enabling modern gaming features such as hardware ray tracing and variable rate shading. The Galaxy has a die size of unknown die size with an unknown number of transistors transistors, featuring 16384 shaders, 1024 TMUs, 0 ROPs, unknown tensor cores tensor cores, and unknown ray tracing cores ray tracing cores. It comes with 288 GB HBM3e memory on a 8192-bit interface, running at 2000 MHz 8 Gbps effective. The GPU operates at 1000 MHz, boosting up to 2400 MHz, with a maximum power draw of 1400 W via no external power connectors. It connects through PCI Express, offers No outputs, measures OAM Module, uses a system-specific cooling design, and launched at an undisclosed price.
