Quick Answers

Which GPU is faster for gaming right now?

Tesla K40m is the faster gaming card right now based on the synthetic data we have. It leads by 1.7% in PassMark G3D (3,143 vs 3,090), which is the best performance signal available in this matchup.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon HD 7790 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. That still leaves it as the safer long-term option on hardware alone.

Which GPU is the better buy today?

Radeon HD 7790 makes the most sense today based on the pricing and value data we have for this matchup. Tesla K40m still makes more sense if max raw gaming performance matters more than value.
