Intel Core Ultra X7 358H Slower than 255H, iGPU Impresses

Key Takeaways

1. Intel has not yet revealed detailed specifications or performance for their Panther Lake CPUs, introduced in mid-October.
2. The Core Ultra X7 358H performs around 20,000 points in Cinebench R23, but is 8.3% slower than the Core Ultra 7 255H under the same power conditions.
3. The older Arrow Lake chip scores an average of 17,812 points, suggesting Panther Lake may be slightly more powerful or less so pending further evaluations.
4. The Core Ultra X7 358H features four performance cores and twelve efficiency cores, with no significant improvements in CPU performance noted.
5. Intel’s Panther Lake laptops are expected to launch at CES in January 2026, with more performance insights anticipated by then.

Intel has previously introduced Panther Lake in mid-October, however, they haven’t provided specifics on the CPUs or their performance yet. Following a positive early Geekbench leak for the integrated graphics, the recent benchmark results from Laptop Review reveal how the Core Ultra X7 358H is performing.

Performance Metrics

The high-speed chipset achieves approximately 20,000 points in Cinebench R23 while consuming 65 watts of power. Laptop Review indicates that this makes the chip 8.3% slower than the Intel Core Ultra 7 255H under the same power conditions. Interestingly, our benchmark records show that the older Arrow Lake chip has an average score of only 17,812 points. More comprehensive evaluations will determine if Panther Lake is slightly more powerful or less so.

Benchmark Insights

Current benchmarks reveal that the Core Ultra X7 358H, which has four performance cores and twelve efficiency cores, does not exhibit significant advancements in CPU performance. The highlight of Intel’s upcoming laptop processors is the Xe3 iGPU featuring twelve compute units, achieving a score of 6,830 in 3DMark Time Spy. This represents a remarkable 72% improvement over the iGPU in the Core Ultra 7 255H.

Future Launches

The initial laptops powered by Intel’s Panther Lake are expected to debut at CES in January 2026, and by then, we anticipate more insights regarding the performance and efficiency of Intel’s next-generation laptop processors.
