GeForce GTX 675MX vs Radeon Pro 555X: Pros, Cons & Final Verdict

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

GeForce GTX 675MX

2012

Why buy it

✅21.7% more average FPS across 50 tracked games in our benchmark data.
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).

Trade-offs

❌2012 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌33.3% higher power demand at 100W vs 75W.

Radeon Pro 555X

2018

Why buy it

✅GeForce GTX 675MX is already obsolete for modern gaming, so Radeon Pro 555X is the less risky modern option long term.
✅Draws 75W instead of 100W, a 25W reduction.
✅More future proof: GCN 4.0 (2016−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce GTX 675MX across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌2018 hardware with 2 GB of VRAM already sits in legacy territory for modern games.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 675MX is the faster gaming card right now. In our data, it leads by 21.7% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon Pro 555X instead at 3,000 vs 2,951, 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 Pro 555X 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 14nm process instead of 28nm, and a newer 2018 generation instead of 2012. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Radeon Pro 555X makes the most sense today based on the pricing and value data we have for this matchup. GeForce GTX 675MX still makes more sense if max raw gaming performance matters more than value.
