Core Ultra X7 358H and Ultra 5 338H score 20K and 16K points, respectively, in Cinebench R23

A site called Laptopreview Club has already leaked 3DMark Time Spy performance figures for Intel’s next-gen Core Ultra 300 series, but it appears they have more data to share, this time involving a CPU benchmark.

Although rumors about the Core 300 series naming have been all over the place, the information is more or less confirmed by now, courtesy of OEMs already testing the new hardware ahead of the 2026 launch. The new lineup adds an “X” suffix and shifts the generation naming to “3th.” The Core Ultra 300 series is expected to include several variants such as 3_8H, 3_5H, and 3_0U, all based on the same Panther Lake architecture.

While everyone expects a major jump in graphics performance thanks to the new Xe3 architecture, possibly offering a 30% to 50% increase over Xe2, not much is known yet about CPU improvements. The rounded figures shared by Laptopreview may give some hints.

If these numbers are accurate, the Intel Core Ultra X7 358H will reach 20,000 points in Cinebench R23 multi-core and around 6,830 points in the Time Spy benchmark. The site also reports a C ore Ultra 5 338H score of 16,000 points, both allegedly achieved at a 60–65 W TDP.

The Ultra X7 358H is said to feature 16 cores combining 4 P-Cores, 8 E-Cores, and 4 LP-Cores. It reportedly boosts up to 4.8 GHz and includes Xe3 graphics with 12 cores. The Ultra 5 338H, on the other hand, which lacks the “X” label, has 12 cores, achieved by halving the E-Cores compared to the 358H, and integrates an Arc B370 GPU with 12 Xe3 cores.

Also worth noting that the the graphics score of 6830 points is higher than the previously discussed 6200 score.
