Intel has addressed performance problems affecting its Arrow Lake processors, which initially underperformed compared to expectations. Updates to the BIOS and Windows, along with a forthcoming firmware update, aim to restore Arrow Lake CPUs to their intended performance levels.
Intel ’s Arrow Lake CPU s didn’t make it on our list of the best processors when they released earlier this year. As you can read in our Core Ultra 9 285K review, Intel ’s latest desktop offering struggled to keep pace with last-gen options, particularly in games, and showed strange behavior in apps like Premiere Pro. Now, Intel says it has fixed the issues with its Arrow Lake range, which accounted for up to a 30% loss in real-world performance compared to Intel ’s in-house testing.
The company identified five issues with the performance of Arrow Lake, four of which are resolved now. The latest BIOS and Windows Updates (more details on those later in this story) will restore Arrow Lake processors to their expected level of performance, according to Intel, while a new firmware will offer additional performance improvements. That firmware is expected to release in January, pushing beyond the baseline level of performance Intel expected out of Arrow Lake. I’m going to dig into all of the issues Intel found, but if you’re just concerned with getting the best performance out of your Arrow Lake CPU, all you need to do is perform a couple of updates. First, make sure you’re running on Windows 11 build 26100.2161 or later. You can see your build version in the About this PC screen in the Windows Settings app. Next, if you’re using a Z890 motherboard, make sure you’ve updated to the latest BIOS. Those two changes will restore Arrow Lake’s performance, according to Intel. Intel's Hallock Returns For Arrow Lake Core Ultra 200 Performance Fix Update Intel’s Robert Hallock returned to Hot Hardware to reveal the changes, noting that the correct drivers and BIOS settings weren’t available to reviewers, which would explain why CPUs like the Core Ultra 5 245K performed much lower than expected. I’ll be testing these updates, but in the meantime, here’s what Intel says went wron
