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

✅Costs $19 less on MSRP ($150 MSRP vs $169 MSRP).
✅Measures 147mm instead of 160mm, a 13mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower PassMark G3D performance (1,880 vs 10,749).
❌Less VRAM, with 1 GB vs 6 GB for high-resolution textures and newer games.
❌No DLSS support; it relies on Upscaling support instead.
❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌Lower G3D Mark per dollar, at 12.5 vs 63.6 G3D/$ ($150 MSRP vs $169 MSRP).

GeForce RTX 3050 6GB

2024

Why buy it

✅+471.8% higher PassMark G3D performance.
✅Delivers 407.5% more G3D Mark for each dollar spent, at 63.6 vs 12.5 G3D/$ ($169 MSRP vs $150 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅500% more VRAM for high-resolution textures and newer games (6 GB vs 1 GB).
✅More future proof: Ampere (2020−2025) on 8nm 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 RTX 3050 6GB better than GeForce GTX 645?

Yes. GeForce RTX 3050 6GB is clearly the better overall GPU here. You are also looking at 10,749 vs 1,880 in G3D Mark. On top of that, GeForce RTX 3050 6GB is a 2024 card with DLSS Super Resolution, while GeForce GTX 645 is a 2010 model from an older generation with no meaningful modern upscaling stack. 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?

GeForce RTX 3050 6GB is the more future-proof choice for 2026 and beyond. You are getting a newer 2024 generation instead of 2010, 471.8% more raw performance headroom, more VRAM at 6 GB instead of 1 GB, and better upscaling support with DLSS 2 Super Resolution (2020) instead of no meaningful modern upscaling stack. That leaves it with more room for heavier textures, tougher ray tracing loads, and higher-end 1440p or 4K gaming over the next few years.

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

GeForce RTX 3050 6GB is the smarter buy by a wide margin. GeForce RTX 3050 6GB is about 12.7% more expensive on MSRP at $169 MSRP versus $150 MSRP, and you are getting 471.8% 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.
