Gaming Performance

No measured FPS data exists for this exact CPU+GPU combination, and the FACT PACK contains no measuredFpsUltraByGame entries. Consequently, all gaming performance figures discussed here are estimates derived from the individual component benchmark scores rather than direct measurement. The GPU's PassMark G3D score of 19,587 and its parity with the RTX 3090 (0.5% delta) and RX 6700 XT (0% delta) suggest that at 1080p ultra settings, this platform should deliver high frame rates in most modern titles, likely exceeding 60 FPS in demanding games and approaching 144 FPS in competitive shooters.

At 1440p, the 8 GB VRAM and 256.0 GB/s bandwidth will accommodate high-quality textures, but the GPU's 15.62 TFLOPS FP32 performance may limit frame rates to the 50-80 FPS range in ultra settings for AAA titles. The CPU's single-thread score of 979 in 3DMark and 1,761 in Cinebench R23 indicate it can support high frame rates without bottlenecking in most games, though CPU-intensive titles with heavy simulation or AI workloads may see reduced performance in crowded scenes. The 16 threads provide headroom for background tasks such as Discord, browser, or streaming software while gaming.

The GPU's 36 RT cores enable ray-traced effects in supported titles, though enabling ray tracing will significantly reduce frame rates given the mobile GPU's power constraints. DLSS using the 144 tensor cores can offset this performance cost, with AI upscaling allowing higher internal resolutions or frame rates. For esports titles at 1080p with competitive settings, the platform should easily exceed 144 FPS in most cases, while more demanding single-player games at ultra settings will likely fall in the 70-100 FPS range. Users targeting 4K gaming should expect frame rates below 60 FPS in most titles, even with upscaling enabled, due to the 8 GB VRAM capacity and 128-bit memory bus limiting bandwidth at high resolutions.
