See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX TITAN X

2015

Why buy it

✅15.8% more average FPS across 50 tracked games in our benchmark data.
✅200% more VRAM for high-resolution textures and newer games (12 GB vs 4 GB).

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌2015 hardware with 12 GB of VRAM already sits in legacy territory for modern games.
❌
149.8% HIGHER MSRP
$999 MSRPvs$400 MSRP
❌Lower G3D Mark per dollar, at 12.6 vs 32.5 G3D/$ ($999 MSRP vs $400 MSRP).
❌212.5% higher power demand at 250W vs 80W.

Radeon RX 6600S

2022

Why buy it

✅Costs $599 less on MSRP ($400 MSRP vs $999 MSRP).
✅Delivers 157.6% more G3D Mark for each dollar spent, at 32.5 vs 12.6 G3D/$ ($400 MSRP vs $999 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
✅Better long-term bet: RDNA 2.0 (2020−2025) on 7nm gives it a newer hardware base for upcoming games.
✅Draws 80W instead of 250W, a 170W reduction.

Trade-offs

❌Lower average FPS than GeForce GTX TITAN X across 50 tracked games in our benchmark data.
❌Less VRAM, with 4 GB vs 12 GB for high-resolution textures and newer games.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX TITAN X is the faster gaming card right now. In our data, it leads by 15.8% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 6600S instead at 13,016 vs 12,621, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon RX 6600S is the safer long-term pick for 2026 and beyond. The case is simple: the newer feature stack, with FSR 3 (2023) and FSR Frame Generation + AFMF (2023), while GeForce GTX TITAN X is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 7nm process instead of 28nm, 28 vs 0 ray-tracing units, and a newer 2022 generation instead of 2015. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon RX 6600S makes the most sense to buy today. It is $599 cheaper on MSRP at $400 vs $999, and it leads G3D-per-dollar by 157.6% (32.5 vs 12.6), which is enough to swing the recommendation its way. GeForce GTX TITAN X still makes more sense if max raw gaming performance matters more than value.
