Arrow Lake-S CPU Upgrades Falter: Microcode 0x114 Results in 18% Performance Decline

Intel’s latest microcode update, known as “0x114,” is falling short of expectations, struggling to address performance woes with its Arrow Lake processors. The new benchmarks have unearthed further declines, adding to Intel’s string of challenges in the consumer market.

Intel’s Arrow Lake desktop CPUs are hitting a rough patch in consumer systems, with a fresh BIOS update failing to deliver the expected performance fixes. This comes on the heels of turmoil with the “Raptor Lake Refresh” series, which faced thermal instability concerns. Intel had observed significant discrepancies in Arrow Lake-S performance between consumer systems and their own tests and tried to resolve these differences with the introduction of the 0x114 microcode.

However, the solution appears elusive as benchmarks shared by CapFrameX reveal ongoing performance setbacks in gaming scenarios. Notably, while testing Intel’s Core Ultra 9 285K processor with Cyberpunk 2077, there was an eye-catching 18% drop in average frames per second—a marked decline that contradicts Intel’s promises of a “double-digit” boost resulting from the BIOS update.

Even more concerning is the reported increase in memory latency, rising by about 14%. Such findings underscore the need for further evidence to support claims about the flaws in the ARL-S BIOS update, but these initial results don’t paint an optimistic picture for consumers relying on Intel’s desktop CPUs.

Looking ahead, industry enthusiasts are keenly anticipating Intel’s media briefing slated around CES 2025. Here, the company plans to address the Core Ultra 200S performance issues, which could shed light on its strategic direction for the Arrow Lake-S series. Until then, users of ARL-S processors can only wait for Intel’s official update to confirm whether these recent benchmarks reflect broader system trends and if performance degradation with the 0x114 microcode is a widespread concern.
