Which Nvidia RTX Spark chip variants were tested on Geekbench?

Two variants were tested: the full 20-core model and a cut-down 18-core version. Both showed similar single-threaded performance, but the 20-core model excelled in multi-threaded benchmarks.

How does RTX Spark compare to competitors in multi-threaded tests?

The 20-core RTX Spark outperforms AMD AI Max+ 395 by 12% and approaches Snapdragon X2 Elite Extreme. However, it falls short of top Apple solutions like the M4 Pro.

Why does RTX Spark's single-threaded performance raise questions?

In single-threaded tests, RTX Spark trails Apple Silicon and Snapdragon X2 Elite but leads AMD and Intel. This may stem from unoptimized drivers during testing.

Quick answer

Geekbench tests for Nvidia RTX Spark revealed two chip variants: a 20-core model and a cut-down 18-core version.

Geekbench has revealed benchmark results for two upcoming Nvidia RTX Spark mobile superchip variants. The first model features a full 20-core CPU configuration (10+10), while the second is a cut-down 18-core version (10+8). Both models delivered comparable single-threaded performance, but the 20-core variant significantly outperformed in multi-threaded tests.

The 20-core RTX Spark scored 23,126 points in multi-threaded benchmarks, surpassing the 18-core version (21,776 points) by 5.8%. Compared to rivals, Nvidia's chip leads AMD AI Max+ 395 by 12% and approaches the market leader, Snapdragon X2 Elite Extreme (25,075 points). However, in single-threaded tests, RTX Spark trails Apple Silicon, with even the base M4 Pro outperforming it by 29%.

Experts note that current results were obtained on pre-release hardware with unoptimized drivers. Performance is expected to improve by the official launch, particularly in multi-threaded scenarios. Nvidia is also optimizing chip compatibility with DRM and anti-cheat systems to ensure seamless launch day performance.
