NVIDIA RTX Spark Benchmarks Leak: 18-Core and 20-Core Specs

NVIDIA RTX Spark processors have appeared in benchmark databases, offering the first concrete look at the company's new laptop silicon. These results matter because they reveal how the new chips stack up against Apple's M4 Max in raw processing power. Buyers waiting for high-performance Windows laptops now have actual performance data to evaluate rather than relying on speculation.

Leaked Geekbench 7 data reveals 64GB unified memory and raw processing power

The leaked entries identify two distinct CPU configurations within the RTX Spark lineup: an 18-core variant and a 20-core variant. Both systems are equipped with 64GB of unified memory, a significant amount for mobile workstations. The device identifiers use generic OEM labels, which means we cannot yet link these benchmarks to specific laptop brands or models.

• CPU Cores (20-core variant): 20
• CPU Cores (18-core variant): 18
• Unified Memory: 64GB
• Geekbench 7 Single-Core (20-core): 2,570
• Geekbench 7 Multi-Core (20-core): 23,126

Performance testing was conducted using Geekbench 7.0.0, providing a standardized comparison point for single-threaded and multi-threaded workloads. The 20-core model achieved a single-core score of 2,570 and a multi-core score of 23,126. Meanwhile, the 18-core version posted a single-core score of 2,541 and a multi-core score of 21,776.

These scores place the RTX Spark chips behind Apple's M4 Max in direct comparisons. The 20-core variant trails the M4 Max by approximately 24.5% in single-core performance and roughly 11% in multi-core tasks. The 18-core model shows a slightly larger gap, lagging by about 25% in single-core and 16% in multi-core benchmarks.

We've been tracking RTX Spark closely — see our earlier coverage on NVIDIA RTX Spark AI PCs Launch. While these initial numbers show the chips are competitive, they are not yet leading the market in raw CPU speed. The lack of pricing and release dates leaves the commercial timeline for these devices unclear.
