Intel Panther Lake Review - Hands On With Their Most Powerful iGPU

I

ntel Panther Lake is finally here—Intel Core Ultra 300 gets a massive iGPU upgrade. I tested the Core Ultra X9 388H + Arc B390 iGPU in real benchmarks and real games (including Cyberpunk). In this hands-on performance test, I’m putting Intel’s new Panther Lake (Core Ultra 300) through weeks of benchmarks, creator tests, AI workloads, and gaming—using a Lenovo reference laptop to focus purely on the chip. The big headline is the Intel Arc B390 iGPU with XeSS features (including multi-frame generation) delivering surprisingly high frame rates—even in demanding titles.
