Processor & Performance

Driving the ROG Strix 18 G815LR-TT299W is the Intel Core Ultra 9 Processor 290HX Plus, a 24-core, 24-thread chip with a 2.7GHz base clock that climbs up to 5.5GHz, backed by 36MB of cache. Intel’s AI Boost NPU adds up to 13 TOPS for on-device AI workloads.

Graphics are handled by the NVIDIA GeForce RTX 5070 Ti Laptop GPU with 12GB of GDDR7 memory. The GPU runs ROG Boost up to 1565MHz at 140W (1515MHz boost clock plus 50MHz OC, with 115W base and 25W Dynamic Boost). It’s built on NVIDIA’s Ada Lovelace architecture with support for DLSS 4, NVIDIA Studio, and Max-Q technologies.

A MUX Switch with NVIDIA Advanced Optimus lets the system route graphics directly to the GPU for gaming or switch to integrated graphics for battery savings.

The laptop carries an 18-inch ROG Nebula Display with 2.5K (2560×1600, WQXGA) resolution in a 16:10 aspect ratio. The IPS-level anti-glare panel covers 100% DCI-P3 and is Pantone Validated.

Refresh rate runs at 300Hz, though the default is 240Hz in Standard, Eco, and Optimized GPU modes — switching to Ultimate GPU mode in Armoury Crate enables the full 300Hz. The panel also supports NVIDIA G-Sync.

On the memory front, there’s 32GB of DDR5-5600 SO-DIMM (16GB × 2) running in dual channel, expandable up to 64GB across two SO-DIMM slots. Memory speed varies by CPU spec.
