Intel's next-generation Core Ultra 300 "Panther Lake" chips are showing strong performance, particularly in integrated graphics. Early tests of the flagship Core Ultra X9 388H indicate a significant boost compared to the previous "Lunar Lake" chips. In 3DMark Time Spy, the new chip scores around 6,233 points with 8,533 MT/s LPDDR5X memory, and about 6,300 points with 9,600 MT/s memory—roughly 33% better than Lunar Lake's Arc 140V, which scored around 4,721 points.
Intel claims Panther Lake is more efficient, offering 40% better performance per watt than the previous Arrow Lake-H and 50% better than Lunar Lake. These figures are based on Intel’s reference designs and may vary in retail models with different settings. The X9 388H is expected to feature a 12-core Xe3 graphics setup, with improvements in efficiency and clock scaling, benefiting from faster LPDDR5X memory.
