Criticism has loomed over Windows on Arm PCs featuring Qualcomm Snapdragon chips, primarily centered on their performance with applications designed for traditional X86 processors. While native apps typically function smoothly, those relying on emulation to bridge the gap between X86 and Arm architectures have faced significant challenges. Qualcomm seeks to address these concerns with its upcoming Snapdragon X Elite processors, but a notable caveat accompanies their touted performance improvements.
During a presentation at the Game Developer Conference, Qualcomm executives conveyed optimism regarding the gaming capabilities of Snapdragon X Elite processors. They asserted that most games listed as the most popular on Steam should run nearly at full speed on these processors. Issam Khalil, a Qualcomm engineer, detailed various approaches for game developers to optimize their titles for Arm architecture, including direct porting or utilizing hybrid Arm64EC apps. Khalil suggested that, given most games’ GPU-bound nature, emulation performance should have minimal impact.
However, obstacles remain, particularly concerning games utilizing kernel-level anti-cheat drivers or AVX instructions. Such games may encounter compatibility issues when run via emulation, potentially affecting titles like Fortnite, Valorant, and Apex Legends. Resolving these compatibility concerns may require developers to rework their games for Arm architecture, posing potential challenges to widespread adoption.
While Qualcomm’s Snapdragon X Elite platform holds promise, its success hinges on the effectiveness of emulation. As Qualcomm aims to compete with Intel’s Core processors, particularly in gaming, the ability of Snapdragon X Elite PCs to seamlessly run applications will dictate their market viability.
