Core Ultra 9 285K tested: 10 must-know facts about Intel's radically new CPUs

Intel's new desktop CPUs are radically different than the Intel CPUs you're used to. Today marks the launch of Arrow Lake, the company's latest architecture for desktop processors, formally sold as the Core Ultra 200S Series. According to Intel's claims, this batch of Core chips is faster and far more power efficient than last-gen Raptor Lake CPUs, while still beating out the competition. However, Arrow Lake isn't notable just for what it does, but also for what it is. As the first set of desktop x86 processors shipped but not fabricated by Intel, TSMC's involvement in their production is but one new standout aspect. Intel has reworked its chip design, too--and the overhaul comes with some quirks, as we discovered during our testing.
