WORLDTECHNVIDIA launches RTX Spark N1X platform with Windows laptops and mini-PC
NVIDIA has rolled out its high-end RTX Spark N1X platform this week, carrying its GB10 technology to Windows, according to ServeTheHome. The rollout spans the Surface Laptop Ultra, roughly half a dozen other laptops and a Windows mini-PC.
Launch spans laptops and a mini-PC
The release is not confined to one machine. Besides the Surface Laptop Ultra, another half-dozen laptops built around the RTX Spark arrived this week, and Microsoft's Surface RTX Spark Dev Box, a Windows mini-PC, rounds out the line-up.
ServeTheHome presents the Surface Laptop Ultra as the most premium Surface laptop to date and the leading edge of a wider Windows effort to encourage use of Arm-based processors.
What the GB10 chip brings together
According to ServeTheHome, GB10 is a high-end design that gathers much of NVIDIA's recent CPU and GPU technology into one low-power chip. The site notes that NVIDIA likens the design to a smaller edition of its Grace Blackwell server architecture; the comparison is not exact, the report says, but it is close. GB10 is a joint effort of NVIDIA and MediaTek, made up of two chiplets: a CPU and memory chiplet designed by MediaTek and a GPU chiplet designed by NVIDIA.
Both chiplets are fabricated on TSMC's 3nm process, the most advanced node at the foundry when GB10 launched. ServeTheHome reports that the CPU die carries ten Arm Cortex-X925 performance cores and ten Cortex-A725 efficiency cores, with each cluster owning a 16MB L3 cache.
Timing and background of the chip
NVIDIA has been shipping the underlying GB10 in Linux systems for about a year, and rumours suggest it intended to bring the chip to market sooner. ServeTheHome calls the RTX Spark N1X the company's first system-on-chip in several years aimed at end-user systems.
The report also points out that the CPU cores are standard Arm designs from the 2024 Cortex lineup rather than derivatives of NVIDIA's Grace. For that reason ServeTheHome considers the chip somewhat behind the curve in CPU technology and expects this to affect performance.
Open questions
- How will the RTX Spark N1X's CPU performance compare with rival Windows processors in practice?
- Will the wider Arm push in Windows extend beyond the launch line-up?
