Intel Arrow Lake 0x114 Microcode Already Out, No Significant Gains—We Tested
Motherboard vendor ASUS began rolling out UEFI firmware (BIOS) updates to its Intel Z890 motherboards that contain Intel's 0x114 Microcode update for Core Ultra "Arrow Lake-S" desktop processors. The new microcode was touted as bringing in performance gains to gaming workloads across the board, with Intel saying that depending on the configuration, one could expect a "roughly 3-8% performance gain." The company said that motherboard vendors should begin releasing BIOS updates with 0x114 "starting January 2025," however, it seems like ASUS is ready with public "stable" (non-beta) BIOS updates with it. We use a ROG Maximus Z890 Hero in our "Arrow Lake-S" reviews, and so promptly grabbed the version 1203 BIOS from the ASUS website, and put it to the test. This also updates Intel ME (management engine) to v19.0.0.1827.
We added our performance testing numbers to our article from yesterday (December 19, 2024), where we had tested the Core Ultra 9 285K with the latest OS-level patches for Windows 11 24H2. Long story short, we do not notice any notable performance gains with the 0x114 microcode update. 0x114 was touted as providing users with additional performance gains after all the OS- and BIOS configuration related issues had been fixed. In its pre-brief from earlier this week, Intel said that the 0x114 microcode update represented additional performance gain opportunities that the company had discovered in the process of identifying and fixing the reasons why the processors fell significantly behind Intel's performance guidance in their launch reviews in October.
We recommend you to once again read our performance testing article from yesterday, we have updated the performance graphs with 0x114 microcode update numbers, and are in the process of providing additional commentary in the article. Here's a teaser:
