Summary

Last week, I spent two days hearing how Microsoft and NVIDIA are "reinventing the PC" with RTX Spark, the new system-on-a-chip powering the Surface Laptop Ultra and several other Windows PCs this fall. It's the first time we've seen powerful Arm CPUs joined together with NVIDIA's Blackwell GPU technology and up to 128GB of ultra-fast unified memory on a single chip. Theoretically, RTX Spark should allow for thin-yet-powerful laptops (and a few small desktops) that can handle AI tasks locally, as well as tackling content creation and gaming.
