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

GeForce GT 635M

2012

Why buy it

✅200% more VRAM for high-resolution textures and newer games (2 GB vs 512 MB).

Trade-offs

❌Lower average FPS than Radeon 6600M across 50 tracked games in our benchmark data.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon 6600M

2023

Why buy it

✅55.9% more average FPS across 50 tracked games in our benchmark data.
✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 512 MB vs 2 GB for high-resolution textures and newer games.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 6600M is the faster gaming card right now. In our data, it leads by 55.9% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward GeForce GT 635M instead at 540 vs 536, 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 6600M 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 6nm process instead of 28nm, 6 vs 0 ray-tracing units, and a newer 2023 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon 6600M makes the most sense today based on the pricing and value data we have for this matchup.
