Utterly ridiculous claim. No GPU comes with 512GB and even 512GB is not sufficient for full precision training of very large models, so why do you need 512GB? 128GB for a GPU on a sub-£4000 workstation is unmatched by any other device - it is in a league of its own.
The HP ZGX Nano G1n AI Station aims to be the perfect entry point for AI developers. With 128 GB of RAM and Nvidia technology on board, it promises server power to go. However, Nvidia's DGX Spark ecosystem is only partially convincing.
