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