Microsoft built its most powerful Surface ever on Nvidia's new chip, and we saw every RTX Spark competitor coming this fall

My Bachelor’s thesis was conducted on the viability of benchmarking the non-functional elements of Android apps and smartphones such as performance, and I’ve been working in the tech industry in some way or another since 2017. In my spare time, you’ll probably find me playing Counter-Strike or VALORANT, and you can reach out to me at adam@xda-developers.com , on Twitter as @AdamConwayIE , on Instagram as AdamConwayIE , or u/AdamConwayIE on Reddit.

The CPU side was co-designed with MediaTek, and Nvidia rates it at 1 petaflop of AI compute, enough to run 120B-parameter models locally with up to a million tokens of context. It's the consumer descendant of the GB10 Grace Blackwell Superchip that powers the DGX Spark and machines like the Lenovo ThinkStation PGX, except this one runs Windows. In a private showcase hosted by Nvidia, we were able to see every RTX Spark-based machine that was announced.
