Nvidia Wouldn't Send Me This Graphics Card - H200 Holy $H!T

Quick Overview

Nvidia's H200 NVL GPU, a professional card built on TSMC's 5nm process, offers significantly higher performance for AI and HPC applications than its predecessor, the H100 NVL, with double the memory capacity and improved bandwidth, though it lacks certain consumer-oriented features like display outputs and full Vulkan/DirectX support, making it optimized for data center AI tasks rather than gaming.

Key Points: The Nvidia H200 NVL is a professional graphics card built on TSMC's 5nm process, featuring the GH100 GPU. It boasts 141 GB of HBM3e memory, offering 4.8 TB/s of memory bandwidth and a 6144-bit bus width. The H200 NVL supports up to 4-slot NVLink bridges, allowing for up to four GPUs to connect and deliver 900 GB/s bidirectional bandwidth. Its performance in AI training and inference is significantly enhanced, with up to 1.7x faster inference performance compared to the H100 NVL. Key features include 16896 CUDA cores, 528 Tensor Cores, and support for confidential computing, but it lacks display outputs and consumer graphics APIs like DirectX and OpenGL. The card's design prioritizes thermal efficiency for server environments, relying on server fans for cooling rather than consumer-style solutions.
