Per NVIDIA's announcement, the Grace-derived CPU in RTX Spark was co-developed with MediaTek and is paired with Blackwell-class GPU hardware and a chip-to-chip interconnect; NVIDIA described unified memory across CPU and GPU as a core feature for large local AI models (NVIDIA press release; NVIDIA news).
Reporting notes the flagship Spark spec mirrors the GB10 / DGX Spark hardware NVIDIA shipped to workstations last year, and that NVIDIA has not published full CPU microarchitecture benchmarks or price points yet (The Verge; Engadget).
Engadget reports that the chip's CPU configuration appears to rely on Arm cores comparable to Cortex X-925 and Cortex-A275 designs, which reviewers flagged as older than the latest C1-Ultra and Oryon cores used elsewhere (Engadget).
Ars Technica and The Verge note Microsoft has invested in an x86-to-Arm translation layer, Prism, and that many mainstream apps already ship Arm-native builds, reducing compatibility friction for Arm Windows PCs compared with earlier Windows-on-Arm attempts (Ars Technica; The Verge).
