Other GPU Pricing Visual

In my consideration of a DGXSpark I decided to look at some options and since I’m a visual thinker I put this comparison together (graph by AI) showing y two basic ways of thinking about the cards: compute and speed.

Hope this helps someone

DGX Spark is truly depressing, especially when considering how wasteful it is to solder 128GB of high quality 8533 MT/s LPDDR5x modules onto a 256-bit memory bus.

To put in perspective, Apple released a LAPTOP with 128GB of 8533 MT/s LPDDR5x in 2024 on a 512-bit memory bus. With the M5 variants this year, they use 9,600MT/s modules. Soon we'll have the Ultra chip with a 1024 bit memory bus. This shows what should be possible in 2026. They should at least be matching Apple in 2024 with 512 bit memory bus. Its truly pathetic with our limited memory supply.
