> support for more than half a terabyte of unified memory — the most ever in a personal computer
AMD Ryzen Threadripper PRO 3995WX released over four years ago and supports 2TB (64c/128t)
> Take your workstation's performance to the next level with the AMD Ryzen Threadripper PRO 3995WX 2.7 GHz 64-Core sWRX8 Processor. Built using the 7nm Zen Core architecture with the sWRX8 socket, this processor is designed to deliver exceptional performance for professionals such as artists, architects, engineers, and data scientists. Featuring 64 cores and 128 threads with a 2.7 GHz base clock frequency, a 4.2 GHz boost frequency, and 256MB of L3 cache, this processor significantly reduces rendering times for 8K videos, high-resolution photos, and 3D models. The Ryzen Threadripper PRO supports up to 128 PCI Express 4.0 lanes for high-speed throughput to compatible devices. It also supports up to 2TB of eight-channel ECC DDR4 memory at 3200 MHz to help efficiently run and multitask demanding applications.
- Shank 2y ago> unified memory So unified memory means that the memory is accessible to the GPU and the CPU in a shared pool. AMD does not have that.
- mythz 2y agoAMD Ryzen AI Max SoC chips have that [1], but it maxes out at 128GB RAM. [1] https://www.amd.com/en/products/processors/laptop/ryzen/ai-300-series/amd-ryzen-ai-max-plus-395.html https://www.amd.com/en/products/processors/laptop/ryzen/ai-3...
- curt15 2y agoWhat about AMD Instinct accelerators like the MI300A[1]? Doesn't that use a single memory pool for both CPU and GPU cores? [1] https://www.amd.com/en/products/accelerators/instinct/mi300/mi300a.html https://www.amd.com/en/products/accelerators/instinct/mi300/...
- ryao 2y agoI suspect that they do not consider workstations to be personal computers.
- agloe_dreams 2y agoNo the comment misunderstood the difference between CPU memory and unified memory. This can dedicate 500GB of high bandwidth memory to the GPU. - ~3.5X that of an H200.
- lowercased 2y agoI don't think that's "unified memory" though.
- JamesSwift 2y ago> unified memory Its a very specific claim that isnt comparing itself to DIMMs

- aaronmdjones 2y ago> It also supports up to 2TB of eight-channel ECC DDR4 memory at 3200 MHz (sic) to help efficiently run and multitask demanding applications. 8 channels at 3200 MT/s (1600 MHz) is only 204.8 GB/sec; less than a quarter of what the M3 Ultra can do. It's also not GPU-addressable, meaning it's not actually unified memory at all.
