GeForce GTX 780M SLI

2013

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Very weak future-proofing: 2013-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌566.7% higher power demand at 200W vs 30W.

Radeon 840M

2024

Why buy it

✅More future proof: RDNA 3+ (2024) on 4nm with a newer platform for upcoming games.
✅Draws 30W instead of 200W, a 170W reduction.
✅More future proof: RDNA 3+ (2024) on 4nm with a newer platform for upcoming games.

Trade-offs

❌Fewer clear downsides in this head-to-head, aside from the usual pricing and availability swings.

Quick Answers

So, is GeForce GTX 780M SLI better than Radeon 840M?

Yes. GeForce GTX 780M SLI is clearly the better overall GPU here. You are also looking at 3,864 vs 3,803 in G3D Mark. On top of that, GeForce GTX 780M SLI is a 2013 card with no meaningful modern upscaling stack, while Radeon 840M 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 840M is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2013, better upscaling support with FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, and a 4nm process instead of 28nm. That broader feature stack should age better as more games lean on modern upscaling and frame-generation support.

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

GeForce GTX 780M SLI can still make sense if you find it at the right price, especially around Unknown MSRP. GeForce GTX 780M SLI is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GeForce GTX 780M SLI is priced in an unclear MSRP range at an unclear MSRP versus an unclear MSRP, and you are getting 1.6% higher G3D Mark. Radeon 840M is the newer 2024 card, so it still has a real case if you care more about newer architecture, lower power draw (30W vs 200W), and future-proofing than about squeezing out the strongest gaming value today.

When does Radeon 840M make more sense than GeForce GTX 780M SLI?

Yes. Radeon 840M 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 (30W vs 200W), future-proofing, and staying closer to an unclear MSRP more than squeezing out the extra headroom of GeForce GTX 780M SLI. The trade-off is that GeForce GTX 780M SLI currently gives you 1.6% higher G3D Mark. G3D-per-dollar is basically tied between them.
