Nvidia RTX Spark comes to Windows PCs with Arm CPU, RTX GPU, and unified memory

The Blackwell-based architecture will also mean that RTX Spark can take advantage of the same DLSS upscaling and frame generation features as other RTX 50-series GPUs, including the controversial upcoming DLSS 5 release. As for the lower-end RTX Spark models, Nvidia didn’t have much to say, but we can glean some details. Rumors and leaked specs (via VideoCardz) suggested that Nvidia was working on two distinct pieces of silicon, one codenamed “N1X” and one codenamed “N1.” Both chips would come in two different flavors—one with all CPU and GPU cores fully enabled and one with some defective cores disabled, a process called “binning” that is commonly used to maximize the amount of sellable silicon you get out of a manufacturing run. The fully enabled N1X aligns with the specs for the RTX Spark; there’s also allegedly an N1X version with 18 CPU cores and 5,120 CUDA cores. The slower, smaller N1 chip is said to include up to 12 CPU cores (8 Cortex-X925 and 4 Cortex-A725) and 2,560 CUDA cores, which is the same number as the desktop GeForce RTX 5050. A binned version of that chip is also said to exist, with 10 CPU cores and 2,048 CUDA cores. The basic N1 is said to support up to 64GB of RAM and have a lower maximum power draw of 45 W. This would put its power envelope closer to something like Intel’s Core Ultra Series 3 (codenamed Panther Lake) chips, implying we could see versions of RTX Spark appear in premium thin-and-light laptops eventually.
