Quick Answers

Which GPU is faster for gaming right now?
GRID P40-8Q is the faster gaming card right now based on the synthetic data we have. It leads by 5.8% in PassMark G3D (7,507 vs 7,098), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
RadeonT 780M is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 4nm process instead of 28nm, 12 vs 0 ray-tracing units, and a newer 2024 generation instead of 2015. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
GRID P40-8Q makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, GRID P40-8Q is the easier value choice. If you care more about 1080p and some 1440p headroom, RadeonT 780M has the stronger long-term case.
