Nvidia's Project Digits is a 'personal AI supercomputer'

Not much was unveiled but it showed a Blackwell GPU with 1PFLOP of FP4 compute, 128GB unified DDR5X memory, 20 ARM cores, and ConnectX powering two QSFP slots so one can stack multiple of them.

edit: While the title says "personal", Jensen did say this was aimed at startups and similar, so not your living room necessarily.

From the size and pricing ($3000) alone, it's safe to conclude it has less raw FLOPs than a 5090. Since it uses LPDDR5X, almost certainly less memory bandwidth too (5090 @ 1.8 TB/s, M4 Max w/ 128GB LPDDR5X @ 546 GB/s). Basically the only advantage is how much VRAM it packs in a small form factor, and presumably greater power efficiency at its smaller scale.

The only thing it really competes with is the Mac Studio for LocalLlama-type enthusiasts and devs. It isn't cheap enough to dent the used market, nor powerful enough to stand in for bigger cards.

I believe $3,000 is for the unmentioned minimum config, no idea on the mentioned 4TB storage and 128GB ram version.

Running a 96GB ram model isn't cheap (often with unified memory 25% is reserved for CPUs), so maybe it will win there.

The NVIDIA press release [0] says "Each Project DIGITS features 128GB of unified, coherent memory and up to 4TB of NVMe storage", which makes it sound like the RAM is fixed size.
