GeForce GT 640 Rev. 2

2013

Why buy it

✅Costs $31 less on MSRP ($99 MSRP vs $130 MSRP).
✅Delivers 31.2% more G3D Mark for each dollar spent, at 11.8 vs 9.0 G3D/$ ($99 MSRP vs $130 MSRP).
✅Draws 49W instead of 86W, a 37W reduction.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2013-era hardware with 512 MB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Radeon HD 5750

2009

Why buy it

✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Quick Answers

So, is Radeon HD 5750 better than GeForce GT 640 Rev. 2?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,168 vs 1,169 in G3D Mark. The bigger reason to prefer Radeon HD 5750 is the overall package: you are getting FSR upscaling.

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

GeForce GT 640 Rev. 2 is the more future-proof choice for 2026 and beyond. You are getting a newer 2013 generation instead of 2009, the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling, and a 28nm process instead of 40nm. 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?

Radeon HD 5750 is the smarter buy by a wide margin. Radeon HD 5750 is about 31.3% more expensive on MSRP at $130 MSRP versus $99 MSRP, and you are getting 0.1% higher G3D Mark. GeForce GT 640 Rev. 2 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does GeForce GT 640 Rev. 2 make more sense than Radeon HD 5750?

Yes. GeForce GT 640 Rev. 2 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 (49W vs 86W), future-proofing, and staying closer to $99 MSRP more than squeezing out the extra headroom of Radeon HD 5750. The trade-off is that Radeon HD 5750 currently gives you 0.1% higher G3D Mark. GeForce GT 640 Rev. 2 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.
