Intel’s Core Ultra X7 358H is starting to find its footing in early benchmarks. With an additional engineering sample now logged, the chip’s multi-core PassMark score has climbed to 32,003 points, nudging past the Core Ultra 7 255H by a slim margin. That closes the performance gap seen in the first two listings and marks the 358H as slightly faster in multi-threaded workloads.
There’s still nuance to the results. In single-core testing, the Core Ultra X7 358H trails the Core Ultra 7 255H by about 1.4%, while its multi-core lead is roughly 4%. As more samples are tested, these numbers are likely to stabilize and could shift in either direction. The latest entry also confirms a 4.8 GHz turbo frequency, though the base clock remains unspecified in the database.
Compared to the sizeable leap from the Core Ultra 7 155H to the 255H—where the 255H delivered nearly 20% higher multi-threaded performance alongside a notable single-core bump—the generational uplift to the 358H looks modest so far. That earlier jump came despite the 155H featuring Hyper-Threading, making today’s smaller gains feel conservative by comparison.
Part of the explanation likely lies in the core makeup. While both the 358H and 255H are listed with 16 cores and 16 threads, the Core Ultra X7 358H reportedly trades two performance cores for two additional low-power efficiency cores. If accurate, that shift prioritizes efficiency, which aligns with the positioning of Panther Lake laptop processors. Intel’s aim appears to be better power savings versus Arrow Lake-H at similar multi-threaded performance levels, a valuable trade-off for thin-and-light notebooks that need long battery life without giving up too much speed.
Graphics may be where the new chip shines brighter. Early indications suggest its integrated GPU should outperform the Xe2-based iGPU found in Arrow Lake-H, which could translate into smoother everyday graphics, accelerated media, and improved light gaming in systems without discrete GPUs.
Key takeaways:
– Multi-core PassMark score: 32,003 points for the Core Ultra X7 358H
– Beats Core Ultra 7 255H by about 4% in multi-core; trails by roughly 1.4% in single-core
– Turbo frequency confirmed at 4.8 GHz; base clock not yet listed
– 16-core/16-thread configuration, with fewer P-cores and more LP-E cores than the 255H
– Early results suggest smaller generational gains than the jump from 155H to 255H
– Panther Lake focus appears to favor power efficiency at competitive performance levels
– Integrated graphics performance is expected to improve meaningfully over Arrow Lake-H’s Xe2 iGPU
It’s early days for the Core Ultra X7 358H, and larger sample sizes typically produce more reliable rankings. For now, the data points to a power-savvy mobile CPU that edges past its predecessor in multi-threaded tasks, keeps close in single-threaded speed, and could deliver a notable boost in integrated graphics—all promising signs for next-gen laptops.
