ASUS ROG G15 with Radeon RX 6800M and Ryzen 9 5900HX Spotted | TechPowerUp It's close to impossible finding a Ryzen 9 mobile processor-powered gaming notebook with a high-end NVIDIA GPU. Having returned to the high-end discrete GPU market with the "Big Navi" Radeon RX 6000 series, AMD is looking to complement its Ryzen 5000M series "Zen 3" Cezanne mobile processors with high-end RDNA2 GPUs of its own. An upcoming model of the ASUS ROG G15 (2021) leaked to the web in a CPU-Z validation database (model: G513QY). This notebook packs a Ryzen 9 5900HX "Cezanne" 8-core/16-thread processor based on the "Zen 3" microarchitecture; but more interestingly, the discrete GPU is Radeon RX 6800M.
The desktop Radeon RX 6800 (non-XT) and RX 6700 XT have shown that AMD has achieved performance/Watt parity/leadership over NVIDIA with high-end GPUs. VideoCardz reports that the RX 6800M is likely based on a maxed-out 7 nm "Navi 22" silicon, with 2,560 stream processors, and 12 GB of GDDR6 memory across a 192-bit wide memory bus. The RX 6800M could play in the same performance league as the GA104-based GeForce RTX 3080 Mobile, given that the desktop RX 6700 XT is leveling up to the desktop RTX 3070. Given the 256-bit memory bus width of the larger "Navi 21" silicon, it's quite possible that AMD comes up with even higher mobile SKUs, so AMD-powered gaming notebooks finally match/beat Intel+NVIDIA combinations.
In my personal opinion it remains to be seen if there will be sufficient stock.
