Submission + - Intel Core Ultra X9 388H Launched: Panther Lake Tests Strong In Lenovo Laptop (hothardware.com)
MojoKid writes: Intel took the wraps off performance testing of its top-end 16-core / 12-Xe Core Ultra X9 388H, aka Panther Lake, mobile processor today, and puts up great numbers essentially across the board. The chip offers class-leading performance and excellent efficiency relative to other mainstream notebook platforms, especially as it relates to graphics and AI workloads. Intel didn't make significant changes to the Cougar Cove (P-Core) And Darkmont (E-Core) microarchitectures in Panther Lake, other than tuning them for manufacturing on Intel's 18A process, but the 12-Xe core iGPU represents a huge leap in performance and Intel's NPU5 is purpose -built for today's local AI workloads. With all of that in mind, it appears that Intel has delivered in spades with Panther Lake and the Core Ultra 300 series for next gen laptops and likely hand-held gaming devices as well. iGPU and NPU performance were both very strong, and CPU performance, particularly in multi-threaded workloads, is highly competitive. Battery life and efficiency were also very good. Despite the test vehicle's large, high-resolution 16-inch; display, the pre-production Lenovo IdeaPad 5 Pro tested lasted for nearly 24 hours untethered from a power outlet, with the screen lit up the entire time.
