X-Plane 12 — Head to Head
Alienware Aurora R16 Gaming Desktop – Intel Core i9-14900KF vs ASUS ROG Strix GT35 Gaming Desktop – Intel Core Ultra 9 285K
Comparing performance for X-Plane 12 · Scoring: 45% CPU / 55% GPU weighted
Alienware Aurora R16 vs ASUS ROG Strix GT35 for X-Plane 12: RTX 4090 pulls a 5.5-point lead that matters in VR and photogrammetry.
The ASUS ROG Strix GT35 scores 92.55/100 against the Alienware Aurora R16's 87/100, a gap driven primarily by the RTX 4090's VRAM headroom and the Core Ultra 9 285K's threading advantage in X-Plane 12's CPU-bound physics pipeline. The Aurora R16 holds its own on standard VFR cross-country legs and non-photogrammetry IFR approaches, where the RTX 4080 Super sustains solid frame times without taxing its 16GB buffer. The GT35 pulls decisively ahead during VR city flyovers over dense photogrammetry zones like KLAX or EGLL with Orbx, and during heavy online multiplayer sessions where the 64GB DDR5 and 4090's 24GB VRAM eliminate the stutter spikes that hit the R16 under sustained load.
