Radeon 760M

2024

Why buy it

✅33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
✅More future proof: RDNA 3.0 (2022−2026) on 4nm with a newer platform for upcoming games.
✅Draws 15W instead of 375W, a 360W reduction.

Trade-offs

❌Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.
❌Lower G3D Mark per dollar, at 0 vs 5.6 G3D/$ (Unknown MSRP vs $999 MSRP).

Radeon HD 7990

2013

Why buy it

✅65.9% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 5.6 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 3 GB vs 4 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2013-era hardware with 3 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌2400% higher power demand at 375W vs 15W.

Quick Answers

So, is Radeon HD 7990 better than Radeon 760M?

Yes. Radeon HD 7990 is clearly the better overall GPU here. Radeon HD 7990 averages 65.9% more FPS across 50 tracked games in our benchmark data. You are also looking at 5,566 vs 5,449 in G3D Mark. On top of that, Radeon HD 7990 is a 2013 card with FSR upscaling, while Radeon 760M is a 2024 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?

Radeon 760M is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2013, more VRAM at 4 GB instead of 3 GB, 100.0% more ray-tracing hardware, and a 4nm process instead of 28nm. That extra memory headroom makes it the safer pick for newer games, heavier textures, and higher settings over time.

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

Radeon HD 7990 is the smarter buy today, but it is not as lopsided as a simple winner label makes it sound. Radeon HD 7990 is priced in an unclear MSRP range at $999 MSRP versus an unclear MSRP, and you are getting 65.9% more estimated average FPS across 50 tracked games in our benchmark data and 2.1% higher G3D Mark. It also leads G3D-per-dollar by 100+%. Radeon 760M is the newer 2024 card, so it still has a real case if you care more about newer architecture, lower power draw (15W vs 375W), and future-proofing than about squeezing out the strongest gaming value today.

When does Radeon 760M make more sense than Radeon HD 7990?

Yes. Radeon 760M 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 (15W vs 375W), future-proofing, and staying closer to an unclear MSRP more than squeezing out the extra headroom of Radeon HD 7990. The trade-off is that Radeon HD 7990 currently gives you 2.1% higher G3D Mark and 65.9% more estimated average FPS across 50 tracked games in our benchmark data. It also leads G3D-per-dollar by 100+%.
