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

GeForce GTX 670MX SLI

2012

Why buy it

✅54.5% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 21.6 G3D/$ (Unknown MSRP vs $99 MSRP).
❌200% higher power demand at 150W vs 50W.

Radeon RX 540

2017

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 21.6 vs 0 G3D/$ ($99 MSRP vs Unknown MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅GeForce GTX 670MX SLI is already obsolete for modern gaming, so Radeon RX 540 is the less risky modern option long term.
✅Draws 50W instead of 150W, a 100W reduction.

Trade-offs

❌Lower average FPS than GeForce GTX 670MX SLI across 50 tracked games in our benchmark data.
❌2017 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 670MX SLI is the faster gaming card right now. In our data, it leads by 54.5% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon RX 540 instead at 2,134 vs 2,075, 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 540 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM, the newer feature stack, with FSR Upscaling / FSR 4 (2025) and FSR Frame Generation (2023), while GeForce GTX 670MX SLI is limited to no meaningful modern upscaling stack and no comparable frame-generation support, a 14nm process instead of 28nm, and a newer 2017 generation instead of 2012. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 540 makes the most sense today based on the pricing and value data we have for this matchup. GeForce GTX 670MX SLI still makes more sense if max raw gaming performance matters more than value.
