Sustained Load Behaviour

Under sustained workloads the 16-core Ultra 9 285H maintains performance with its 24MB Smart Cache and 16 threads while the RTX 5070 delivers up to 988 TOPS of AI compute. The 144Hz WUXGA panel keeps motion clear during extended sessions. The factory box seal may be opened for RAM or SSD upgrades and the unit carries a one-year warranty on original components. Buyers who need more than 64GB of memory or a higher refresh rate panel should consider other configurations.
