Discussion Nvidia Blackwell in Q1-2025

Probably installed with the Uno Reverse card, ASUS style.

Must've been unusually high quality to survive reverse polarity and not explode immediately after being turned on.

Ooh, the GB10 chip that's in the DGX Spark is claimed to be using TSMC N3 for both the CPU and GPU. Also the GPU die is derived from GB100 and not the gaming chips.

Still very lacking in the memory bandwidth tho - 301 GB/sec.

It will be interesting see a matchup with Strix Halo.

It says the TDP is 140 W so not really a laptop chip. (Course tell that to Intel)

There are lots of strix Halo boxes using about that much power.

Here is a guy comparing 3 Halo boxes where he says it can use a peak of 120 watts, peak 140.

in 2025 even 13'' thin laptops can do 140W total sustained without throttling

16'' 2kg class can do upwards of 200W

It will be roughly a Nvidia L4 combined with 20 core ARM, just with the latest gen 5 cuda cores instead of gen 4. The L4 does 30 TFLOPs FP32, while the GB10 is said to have 31 TFlops FP32 and they both have the same memory bandwidth, just that the GB10 may have up to 128GB unified memory, vs the L4 having 24GB dedicated memory (the unified memory is shared for both the ARM CPU cores and the GPU).

Doesn't sound like anything I'd want to put on my lap.

It also sounds like the battery should be specified in Wm (watt minutes) instead of Wh (watt hours).

The raw specs are similar to the 5070, even though they claimed it was using the GB100 version.

Without the memory bandwidth of course.
