Is it 128 gb ram or vram?

The initial benchmarks I saw didn’t really have the DGX spark (GB10) doing much better in generation throughput than the AMD Strix Halo. Prefill, the GB10 does pretty well, much better than the Strix.

Memory bandwidth is 273 Gb/s. Which is nowhere near a GPU’s. It’s a 4K machine. Personally, I’d rather have two GPUs and run a quantize model. I have two 32GB AMD r9700 cards, cost $2600. Quantized models get me 120K ish of context window and TPS is about 60% of what I see with the same model on my 4090 (which only has enough vram to load weights and about 6K context).

Sure I can’t run a 100B+ model but neither can a single GB10 unless no context window is what you are going for. So you buy a second 4K machine?
