This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

Radeon R7 250X

2014

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 22.9 vs 0 G3D/$ ($99 MSRP vs Unknown MSRP).

Trade-offs

❌Very weak future-proofing: 2014-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌100% higher power demand at 80W vs 40W.

RadeonT 660M

2023

Why buy it

✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.
✅Draws 40W instead of 80W, a 40W reduction.
✅More future proof: RDNA 2.0 (2020−2025) on 6nm with a newer platform for upcoming games.

Trade-offs

❌Lower G3D Mark per dollar, at 0 vs 22.9 G3D/$ (Unknown MSRP vs $99 MSRP).

Quick Answers

So, is Radeon R7 250X better than RadeonT 660M?

Yes. Radeon R7 250X is clearly the better overall GPU here. You are also looking at 2,269 vs 2,221 in G3D Mark. On top of that, Radeon R7 250X is a 2014 card with FSR upscaling, while RadeonT 660M is a 2023 model from an older generation with FSR upscaling. So this is not really a tight same-tier comparison. It is more a modern card against an older, weaker alternative.

Which one is more future-proof for 2026 and beyond?

RadeonT 660M is the more future-proof choice for 2026 and beyond. You are getting a newer 2023 generation instead of 2014, 100.0% more ray-tracing hardware, and a 6nm process instead of 28nm. That makes it the safer long-run choice for modern games.

Which one is the smarter buy today, not just the cheaper card?

Radeon R7 250X can still make sense if you find it at the right price, especially around $99 MSRP. Radeon R7 250X is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. Radeon R7 250X is priced in an unclear MSRP range at $99 MSRP versus an unclear MSRP, and you are getting 2.2% higher G3D Mark. RadeonT 660M is the newer 2023 card, so it still has a real case if you care more about newer architecture, lower power draw (40W vs 80W), and future-proofing than about squeezing out the strongest gaming value today.

When does RadeonT 660M make more sense than Radeon R7 250X?

Yes. RadeonT 660M is still an excellent gaming GPU in 2026: it is still comfortable for 1080p and decent for 1440p, though 4K is more situational. It makes more sense if your priority is newer architecture, lower power draw (40W vs 80W), future-proofing, and staying closer to an unclear MSRP more than squeezing out the extra headroom of Radeon R7 250X. The trade-off is that Radeon R7 250X currently gives you 2.2% higher G3D Mark. It also leads G3D-per-dollar by 100+%.
