Nvidia’s RTX Spark laptop CPU with 20 cores achieved a multi‑core score of 23,126 in Geekbench 7, about 11 percent lower than Apple’s 14‑core M4 Max result of 25,957. The chip, codenamed N1X, had posted lower scores in earlier leaks, but recent tests using the “Balanced” power profile on two configurations equipped with 64 GB of unified memory showed improved performance.

The 20‑core model (OEMQAJ 766_MIS) recorded a single‑core score of 2,570 and a multi‑core score of 23,126, while the 18‑core variant (OEMQAJ OEMQAJ Product) posted 2,541 and 21,776 respectively. Compared with the M4 Max, the 20‑core RTX Spark is 1.14 percent faster in single‑core and 6.2 percent faster in multi‑core, but remains 11 percent slower overall in multi‑core; the 18‑core version is 24.5 percent slower in single‑core and 16.6 percent slower in multi‑core. The GPUs use different CUDA core counts—5,120 for the lower‑spec model and 6,144 for the higher‑spec model—though the Blackwell GPU architecture matches that of desktop RTX 5070 and RTX 3080 units, and performance equivalence has not been confirmed.

The figures come from prototype benchmarks with unfinished Windows 11 ARM64 drivers, indicating that real‑world results may differ; additional testing will be required to assess the impact.
