“The RTX Spark superchip features an NVIDIA Blackwell RTX GPU with 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision, connected via the NVIDIA NVLink®-C2C chip-to-chip interconnect to a high-performance, 20-core NVIDIA Grace™ CPU.
MediaTek, a market leader in Arm-based system-on-a-chip designs, collaborated with NVIDIA on the custom CPU design, contributing to its best-in-class power efficiency, performance and connectivity.“

Nvidia Grace is an ARM core.
And Mediatek? Oof. I assume the SOC comes pre compromised out of the box.
It has 6,144 CUDA cores is similar to a RTX 4070 (5,888) but a lot less than a 4090 (16,384), but what it does have is support for FP4.
When they claim "1 Petaflop AI compute", thats what they mean. For comparison, a RTX 4090 has ~1.3 Petaflops of FP8 processing.
The second big deal is the NVLink-C2C interconnect, which provides up to 900 GB/s of bidirectional bandwidth between GPU and CPU. For comparison, the Apple M4 has 120 GB/s and the M3 Ultra has 819 GB/s. Notably, the Apple M series does not have FP4 support, so this could mean a significant performance improvement over Apple's offerings.
Considering how much Valve invested into ARM emulation, it's quite possible the next Steam Deck/handheld will use a variation of this (or at least there will be one using this as the SoC).
