Intel looks ready to shake up its laptop processor lineup with a new Core Ultra X series, which has started appearing in leaks ahead of the Panther Lake launch. The lineup reportedly includes the Ultra X7 368H, Ultra X7 358H, Ultra 5 338H, and the flagship Ultra X9 388H. These chips are rumored to push Performance core boost clocks to 5.0–5.1 GHz, while the built-in Xe3 graphics could run as high as 2.5 GHz. One of the more detailed leaks describes the Core Ultra X7 358H, which is said to feature 4 Performance cores, 8 Efficient cores, and 4 Low-Power Efficient cores, paired with 12 Xe3 GPU cores. The Ultra X7 368H is very similar but runs at slightly higher clocks, while the Ultra X9 388H stands at the top of the stack with a 5.1 GHz boost clock.
