GeForce GT 640 Rev. 2

2013

Why buy it

✅Costs $51 less on MSRP ($99 MSRP vs $150 MSRP).
✅Delivers 51.8% more G3D Mark for each dollar spent, at 11.8 vs 7.8 G3D/$ ($99 MSRP vs $150 MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).

Trade-offs

❌Very weak future-proofing: 2013-era hardware with 512 MB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌226.7% higher power demand at 49W vs 15W.

Radeon RX Vega 10 Ryzen 7 3700C

2020

Why buy it

✅Draws 15W instead of 49W, a 34W reduction.
✅More future proof: Vega (2017−2020) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.

Quick Answers

So, is GeForce GT 640 Rev. 2 better than Radeon RX Vega 10 Ryzen 7 3700C?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,168 vs 1,166 in G3D Mark. The bigger reason to prefer GeForce GT 640 Rev. 2 is the overall package: you are getting no meaningful modern upscaling stack.

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 more VRAM at 512 MB instead of Unknown and the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling. 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 640 Rev. 2 can still make sense if you find it at the right price, especially around $99 MSRP. GeForce GT 640 Rev. 2 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GeForce GT 640 Rev. 2 is about $51 cheaper on MSRP at $99 MSRP versus $150 MSRP, and you are getting 0.2% higher G3D Mark. Radeon RX Vega 10 Ryzen 7 3700C is the newer 2020 card, so it still has a real case if you care more about newer architecture and lower power draw (15W vs 49W) than about squeezing out the strongest gaming value today.

When does Radeon RX Vega 10 Ryzen 7 3700C make more sense than GeForce GT 640 Rev. 2?

Yes. Radeon RX Vega 10 Ryzen 7 3700C is still an excellent gaming GPU in 2026: it is still fine for 1080p, but 1440p and especially 4K require more compromise. It makes more sense if your priority is newer architecture, lower power draw (15W vs 49W), and staying closer to $150 MSRP more than squeezing out the extra headroom of GeForce GT 640 Rev. 2. The trade-off is that GeForce GT 640 Rev. 2 currently gives you 0.2% higher G3D Mark. It also leads G3D-per-dollar by 51.8%.
