Intel’s “Arrow Lake” desktop AI processors were officially announced on October 10, 2024, following a lengthy delay. They arrive in five flavors, ranging from Core Ultra 5 through Core Ultra 9. We got our hands on CPUs from both ends of the performance spectrum, and following plenty of testing, it became clear that power efficiency was the target with these new chips.
As it turns out—revealed in a new blog post on Intel’s website—raw gaming performance did not shape up as intended when the chips arrived in reviewers’ hands. Intel has now concluded an investigation into the issue that began on October 26. Five major performance issues were discovered, and four fixes have already been pushed out via Windows 11 and BIOS updates.
Intel’s five primary Core Ultra Series 200S fixes
Intel points out in its blog post that “editorial conclusions on gaming performance were more polarized, with noteworthy statistical variation from one article to the next.” That aligns with what Windows Central Senior Editor Ben Wilson had to say in his Core Ultra 5 245K review:
“Intel’s new Core Ultra Series 2 might seem unusual to some enthusiasts, with gamers expecting a generational leap that was never actually promised. Instead, we get a productivity breakthrough with a dedicated NPU finally making its way to desktops as power efficiency becomes the overall target in this generation.”
Intel started investigating why gaming performance quoted by reviewers wasn’t the same as what was seen in its own testing, and it’s now wrapped up after discovering five primary issues.
Here are the five root causes with quotes pulled from Intel:
- Missing PPM Package: “Intel incorrectly scheduled this Windows Update package for user/retail availability, not reviewer availability.” — Resolved in Windows 11 build 26100.2161
- Intel APO Could Not Take Effect: “The missing Intel PPM placed the processor into an aberrant state where APO could not take effect.” — Resolved in Windows 11 build 26100.2161
- BSOD When Launching Easy Anti-Cheat Titles: “A known issue between Windows 11 24H2 and the April 2024 (or older) Easy Anti-Cheat driver bundled with PC games.” — Resolved via an updated Epic Games Easy Anti-Cheat driver.
- Select Performance Settings Misconfigured in Reviewer BIOSes: “Consistency of VIP settings not sufficiently re-validated or enforced by Intel.” — Resolved in BIOS updates for Z890 motherboards.
- New BIOS Performance Optimizations: “Intel has additionally identified a small selection of performance optimizations that are recently developed, or were not ready for the motherboard BIOS images released thus far.” — Unresolved but expected to be fixed via BIOS update in January 2025.
The Core Ultra 200S lineup includes the Core Ultra 5 245KF, Core Ultra 5 245K, Core Ultra 7 265KF, Core Ultra 7 265K, and Core Ultra 9 285K, and it looks like these root causes can affect all chips.
Intel strongly suggests going through the crucial updates as soon as possible to negate the performance issues. Windows 11 version 26100.2314 (or newer) is where you should be, and your motherboard BIOS should also have the latest drivers. These can usually be sourced from your motherboard manufacturer’s official website.
How much of a performance boost can you expect with these updates?
Unfortunately, a mix of any of these five issues could be plaguing your Arrow Lake desktop CPU, so it’s hard to say exactly how much of a performance increase you’ll see once the bugs are gone.
Intel states that it will deliver a more comprehensive update on the situation at CES 2025, with a closer look at performance improvements. With AMD’s Ryzen X3D CPUs cornering the PC gaming market, Intel had better hope that it will have some overly positive news to share in a few weeks at CES.
