Nvidia RTX Spark N1X Laptop Chip Surfaces in Prototype and Benchmarks
Key points
- Nvidia RTX Spark N1X SoC found in a Microsoft Surface Laptop Ultra prototype.
- N1X features 10 MediaTek-designed ARM CPU cores and an RTX 4070-class GPU.
- Prototype had 24 GB of unified LPDDR5X memory.
- Geekbench shows 20-core (23,126 multi-core) and 18-core (21,776 multi-core) RTX Spark variants.
- Multi-core scores are competitive with existing mobile chips like Snapdragon X2 Elite Extreme.
Prototype Microsoft Surface Laptop Ultra Revealed
A prototype Microsoft Surface Laptop Ultra, equipped with an Nvidia RTX Spark N1X System-on-a-Chip (SoC), has been observed. This pre-release hardware was noted to have 24 GB of unified LPDDR5X memory, though the N1X can support up to 128 GB.
The N1X SoC is designed for "AI laptops" and includes 10 MediaTek-designed ARM CPU cores in a 5 performance-core, 5 efficiency-core configuration, supporting 20 threads. Its integrated GPU is described as comparable to a desktop RTX 4070 or a mobile RTX 5070.
Early Performance and Stability
Initial testing of the prototype indicated mixed performance results, attributed to pre-production drivers and system instability. While some AI tests were attempted, reliable operation was limited due to the early stage of the hardware and software.
Geekbench Listings Confirm Variants
Separate Geekbench listings have surfaced for Nvidia's RTX Spark, revealing two distinct CPU core configurations. One variant features 20 CPU cores (10 performance + 10 efficiency) clocked at 4.0 GHz, while another has 18 cores (10 performance + 8 efficiency) clocked at 3.9 GHz.
Benchmark Scores
The 20-core RTX Spark model achieved a single-core score of 2,570 points and a multi-core score of 23,126 points in Geekbench. The 18-core variant scored 2,541 points in single-core and 21,776 points in multi-core. These multi-core results are competitive with other Windows-running SoCs, with the Snapdragon X2 Elite Extreme holding the current record at 25,075 points.
Implications for the Laptop Market
These early appearances and benchmarks suggest Nvidia's entry into the high-performance laptop superchip market with strong multi-core capabilities. The N1X aims to provide an alternative to existing solutions for non-datacenter AI workloads, leveraging unified memory and capable GPUs.
