About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Head-to-Head Verdict, Benchmarks, Value & Long-Term Outlook

This comparison brings together gaming FPS, raw graphics performance, VRAM, feature set, power efficiency, pricing context, and long-term value so you can see which GPU actually makes more sense.

GeForce GTX 645

2010

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 12.5 vs 0 G3D/$ ($150 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).

Trade-offs

❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌1233.3% higher power demand at 200W vs 15W.

Intel UHD Graphics 770

2022

Why buy it

✅Less risky long-term buy than GeForce GTX 645: it remains the more sensible modern option while GeForce GTX 645 is already obsolete for modern gaming.
✅Draws 15W instead of 200W, a 185W reduction.
✅More future proof: Generation 12.2 (2022−2023) on 10nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 1 GB for high-resolution textures and newer games.

Quick Answers

So, is Intel UHD Graphics 770 better than GeForce GTX 645?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,880 vs 1,914 in G3D Mark. The bigger reason to prefer Intel UHD Graphics 770 is the overall package: you are getting a newer generation, no meaningful modern upscaling stack, plus much lower power draw (15W vs 200W).

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

Intel UHD Graphics 770 is the more future-proof choice for 2026 and beyond. You are getting a newer 2022 generation instead of 2010 and a 10nm process instead of 40nm. That makes it the safer long-run choice for modern games.

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

Intel UHD Graphics 770 is the smarter buy by a wide margin. Intel UHD Graphics 770 is priced in an unclear MSRP range at an unclear MSRP versus $150 MSRP, and you are getting 1.8% higher G3D Mark. GeForce GTX 645 really only makes sense now as a very cheap stopgap or a used-market placeholder.

Is GeForce GTX 645 still worth buying for gaming in 2026?

No, not for a fresh gaming build. GeForce GTX 645 is 2010 hardware with 1 GB of VRAM, 1,880 in G3D Mark, and no meaningful modern upscaling stack. That is simply too far behind to be an easy modern recommendation.
