This latest review examines the "out-of-the-box performance" across both operating systems for the new Intel CPU. This benchmark series builds upon initial Linux-focused benchmarks for Panther Lake's CPU performance and its integrated Xe3 graphics (Intel Arc B390), which Phoronix began publishing last week. The current comparison offers insights into how this next-generation Intel platform performs natively on Linux compared to Windows.
