Lenovo recently sent over their new ThinkPad P1 Gen 8 laptop for review under Linux. My Linux review on that ThinkPad P1 Gen 8 laptop will be coming up in the near future along with some other benchmarks from that premium mobile workstation. But with this being the first time I've had an Intel Core Ultra 7 255H "Arrow Lake H" device at Phoronix, here are some standalone benchmarks looking at the CPU performance of that 16-core mobile processor compared to various other Intel and AMD SoCs in different laptops while running Ubuntu Linux.
