Intel announces Arrow Lake fix coming within a month — Robert Hallock confirms poor gaming performance is due to optimization issues

Intel’s Robert Hallock has confirmed that Intel’s Core Ultra 200S series launch did not go as planned. In a live stream with

, Hallock revealed that optimization issues with the Arrow Lake platform were the primary cause of degradation in gaming (versus Intel’s previous-gen Raptor Lake chips).

Intel identified a number of multifactored issues that caused Arrow Lake to exhibit bizarre performance characteristics in some workloads. Hallock revealed that certain (apparently random) combinations of settings at the BIOS and OS level were able to create memory latency as high as 180ns — over 2x worse than what Arrow Lake’s memory latency operates at normally (70 – 80ns).

Despite this memory latency issue, Hallock confirmed to HotHardware that Arrow Lake’s gaming performance regression compared to Raptor Lake was not related to memory latency, nor was it caused by Intel’s decision to swap to a tile-based architecture. Instead, Arrow Lake’s underwhelming gaming performance was caused by tuning and optimization issues. 

According to Hallock, Arrow Lake’s performance from third-party reviewers did not align with what Intel saw in its internal testing. Hallock noted there was a massive disconnect between third-party review performance and Intel’s internal testing. 

Intel is purportedly working on a large internal response to fix all of these issues. Hallock did not describe in detail the exact issues are plaguing Arrow Lake’s performance scores, but he did say that Intel will have a full audit that explains exactly what went wrong with the launch of Arrow Lake and an outline of what the company is going to do to fix it. 

Responding to a question from Tom’s Hardware managing editor Paul Alcorn, Hallock said that Intel is hoping to have at least a couple of fixes for Arrow Lake by the end of November — or by early December at the latest. 

That Intel recognizes Arrow Lake’s poor launch and massive optimization issues is… encouraging. The Core Ultra 200S series was arguably one of Intel’s worst launches of all time, with gaming performance coming in as the chip’s Achilles’ heel.

In our Core Ultra 9 285K review, the flagship Arrow Lake chip performed worse than the Core i9-14900K in our 14-game 1080p Geomean — even on super fast 8200 MHz DDR5 CUDIMMs. Arrow Lake’s debut was made even more embarrassing with the launch of AMD’s Ryzen 7 9800X3D, which performed up to 60% faster than the Core Ultra 9 285K in games.
