With now more samples, the Core Ultra X7 358H appears to do well, and it's finally scoring higher numbers than its direct predecessor.
Intel Core Ultra X7 358H Brings Multi-Core PassMark Score to 32,003 Points, Beating Core Ultra 7 255H
Intel Panther Lake's Core Ultra X7 358H appeared on PassMark for the first time a few days ago, but due to just two samples being tested on the platform, the scores were kinda unimpressive. Today, after one more early engineering sample, we have scores already noticeably higher than before, not only shrinking the performance gap between 358H and 255H, but also revealing the former to be slightly faster.
The performance still feels lackluster at the moment, considering the Ultra X7 358H loses to the Core Ultra 7 255H by 1.4% in the single-core test and is just 4% faster in the multi-core benchmark. We might see this changing in the near future as more tested samples will deliver more accurate results. This time, the turbo speed of 4.8 GHz was also confirmed from the test page, but the base clock isn't visible yet.
That said, the generational uplifts are quite small compared to going from Core Ultra 7 155H to Core Ultra 7 255H, where we had the 255H offering nearly 20% higher multi-threaded performance and also a similar uplift in single-core prowess. This was despite the 155H having hyperthreading enabled. We don't know how big an impact a few dozen of such samples will make on the score, but the early impressions of Panther Lake chips do not look amazing.
Core Ultra X7 358H does have some differences in the core configuration, even though we have the same 16-core/16-thread config as the 255H. The X7 358H has two fewer P-cores, but two additional LP-E cores, which should explain the smaller generational uplifts. As per Intel, the Panther Lake SKUs are designed to save more power vs Arrow Lake-H, considering we keep both at the same performance level in multi-threaded tasks. As far as its integrated graphics go, we do expect it to be much faster than the Xe2-based iGPU on the Arrow Lake-H, as has been witnessed in early benchmarks.
