in real world performance, thermals among the cpu matter more since these are generally used in light laptops, performance is much closer

Both of these CPU can be used with the new Asus NUC 15 Pro. I don't know if the Ultra 7 255H is worth $300 more than the Ultra 5 225H. Yes, the CPU multicore score is better by 17 to 25% and the iGPU is better by 18%. Value hunters are better off with an Intel Ultra 5 225H CPU. People wanting a high-performance Intel CPU should go after the Intel Ultra 7 255H.

Core Ultra 5 225H should be 12 threads, right? February 12, 2025 at 05:36 PM
Is it a mistake, should be 4+8.
