Panther Lake's Core Ultra 5 338H + Arc B370 Close the Gap to Arc B390 in Early Benchmarks
Notebookcheck’s early tests of Intel’s Panther Lake Core Ultra 5 338H with Arc B370 (10 Xe cores) show solid CPU performance comparable to Ryzen AI 9 465 at similar TDP, while the Arc B370 GPU delivers a notable uplift but trails the Arc B390 by a small margin. At 20W the B370 is virtually identical to the B390, and at 35W the gap grows to about 6%. The unit tested was an engineering sample running at 35W, with retail units expected in the coming weeks.
