The flagship Panther Lake chip is looking quite good, and considering it has the fastest iGPU as well, it's going to be a good upgrade over the predecessor.
Core Ultra X9 388H Benchmarked In PassMark, Delivering Noticeable Multi-Threaded Gains Over Core Ultra 9 285H
Intel's latest Core Ultra Series 3, aka Panther Lake CPUs, have been showing some good performance boost compared to its predecessors. It's probably the only mobile CPU series that brought both stronger CPU and iGPU prowess over the previous-generation. As far as we have seen, the leaks have shown decent performance uplifts, particularly in the multi-threaded performance, and the integrated graphics have hugely improved as well, thanks to the Xe3 architecture.
If you have been waiting for benchmark leaks for the flagship Panther Lake chip, the Core Ultra X9 388H processor, we have published a few previously, but this is the first time the CPU has been benchmarked in PassMark. Previously, it was seen on Geekbench, where it totally dominated its predecessor, the Core Ultra 9 285H, and also traded blows with the Ryzen AI Max+ 395. In the latest benchmark, we are again seeing the Ultra X9 388H easily beating the Ultra 9 285H in multi-threaded performance, delivering nearly 10% higher score.
There are currently two entries for the CPU, and we can see that the single-core performance is on par with the 285H. However, if we take a look at the second entry, the Ultra X9 388H delivers slightly higher single-core score and a godo 17% uplift in multi-threaded test. Still, it's unfair to cherry-pick only one result as the 285H can be seen delivering similar results if we consider its best scores. However, considering various benchmarks, we can clearly see that the X9 388H has a noticeable performance edge over the 285H while having the same number of cores, but keep in mind that both have different core configurations.
The Panther Lake chip uses two fewer Performance cores and brings two additional LP-E cores for efficient operation. Also, the 388H is rated at a much lower TDP than the 285H, and can boost up to 5.1 GHz, while the 285H can boost up to 5.4 GHz. Moreover, its Arc B390 integrated graphics is far ahead of whatever the Core Ultra Series 2 has to offer.
