GeForce GT 630M

2012

Why buy it

✅100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
✅More future proof: Kepler (2012−2018) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Very weak future-proofing: 2012-era hardware with 2 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 0 vs 3.9 G3D/$ (Unknown MSRP vs $130 MSRP).
❌50% higher power demand at 45W vs 30W.

Mobility Radeon HD 4830

2009

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 3.9 vs 0 G3D/$ ($130 MSRP vs Unknown MSRP).
✅Draws 30W instead of 45W, a 15W reduction.

Trade-offs

❌Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2009-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Quick Answers

So, is GeForce GT 630M better than Mobility Radeon HD 4830?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 521 vs 512 in G3D Mark. The bigger reason to prefer GeForce GT 630M is the overall package: you are getting a newer generation, no meaningful modern upscaling stack.

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

GeForce GT 630M is the more future-proof choice for 2026 and beyond. You are getting a newer 2012 generation instead of 2009, more VRAM at 2 GB instead of 1 GB, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling, and a 28nm process instead of 55nm. 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?

GeForce GT 630M is the smarter buy by a wide margin. GeForce GT 630M is priced in an unclear MSRP range at an unclear MSRP versus $130 MSRP, and you are getting 1.8% higher G3D Mark. Mobility Radeon HD 4830 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is Mobility Radeon HD 4830 still worth buying for gaming in 2026?

No, not for a fresh gaming build. Mobility Radeon HD 4830 is 2009 hardware with 1 GB of VRAM, 512 in G3D Mark, and FSR upscaling. That is simply too far behind to be an easy modern recommendation.
