Intel Xe3 iGPU benchmark leak shows significant improvement

The first benchmark results for Panther Lake's Xe3 iGPU have surfaced online, giving us our first look at the performance potential of the new 12-core integrated GPU. The leak comes from a Geekbench entry for the upcoming Core Ultra X7 358H CPU, one of the first chips confirmed to carry Intel's new top-tier mobile branding.

Various Panther Lake benchmark scores were spotted by Benchleaks, all linked to an unannounced Asus ROG Zephyrus G14 laptop. These entries showed the Core Ultra X7 358H as a 16-core CPU, featuring 4 P-cores, 8 E-cores, and 4 LPE-cores, boosting up to nearly 4.8 GHz. This CPU is paired with 32 GB of LPDDR5X.

The focus of these benchmarks, however, is the integrated Xe3 GPU. In the Geekbench OpenCL test, the 12-core iGPU scored between 51K and 53K points. While Geekbench's OpenCL test isn't always the most flattering benchmark for Intel's integrated graphics, this score still represents a healthy 25% improvement over the previous generation “Arrow Lake-H” Arc iGPU in the same test. Perhaps more interestingly, this level of performance puts the Panther Lake iGPU roughly on par with Nvidia's laptop GeForce RTX 3050 and even outperforms Intel's own discrete Arc A550M laptop GPU.

Note that this is almost certainly an early engineering sample running on unoptimised drivers. Performance could still improve as Intel refines the software stack ahead of the official launch. Still, this early result is a promising sign for the graphics capabilities of the upcoming Panther Lake platform.
