  "text": "Nvidia is proposing a beast of a CPU system for Windows PCs.\nIt has 128 GB of shared memory and comes with up to 6,144 state-of-the-art CUDA cores. \n\nCPU wise, the chip has 10 performance cores and 10 efficiency cores. The performance cores are based on the Cortex-X925. These chips appear to support six 128-bit SIMD execution units (SVE2), not as good as recent AMD chips, but better than Apple Silicon (on paper).\n\nThe game changer is the unified 128 GB memory. That is the path Apple took years ago. Instead of separate memory for the CPU and GPU, everything shares a single pool. It is increasingly popular.\n\nThe memory is not as fast as dedicated GPU memory, but it is cheap enough while delivering enough bandwidth to run AI models locally.\n\nI am not sure how many people will run AI models locally. It still seems like a niche application to me. However, it will make decent machines to play video games.\n\nIt will be interesting to see how Intel and AMD respond. I think that the AVX-512  instructions supported by all recent AMD processors are far superior to the SVE2 instructions of the Cortex-X925. They can eat more data and they are more versatile. But Intel has been shy, thus far, in making it available on customer systems.",
