GeForce GTX 645

2010

Why buy it

✅Costs $179 less on MSRP ($150 MSRP vs $329 MSRP).
✅Measures 147mm instead of 242mm, a 95mm shorter card that is more SFF-friendly.

Trade-offs

❌Lower PassMark G3D performance (1,880 vs 16,995).
❌Less VRAM, with 1 GB vs 12 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 51.7 G3D/$ ($150 MSRP vs $329 MSRP).

GeForce RTX 3060

2021

Why buy it

✅+804% higher PassMark G3D performance.
✅Delivers 312.2% more G3D Mark for each dollar spent, at 51.7 vs 12.5 G3D/$ ($329 MSRP vs $150 MSRP).
✅Access to DLSS 2 Super Resolution (2020).
✅1100% more VRAM for high-resolution textures and newer games (12 GB vs 1 GB).
✅More future proof: Ampere on 8nm with a newer platform for upcoming games.

Trade-offs

❌64.6% longer card at 242mm vs 147mm.

Quick Answers

So, is GeForce RTX 3060 better than GeForce GTX 645?

Yes. GeForce RTX 3060 is clearly the better overall GPU here. You are also looking at 16,995 vs 1,880 in G3D Mark. On top of that, GeForce RTX 3060 is a 2021 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 3060 is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2010, 804.0% more raw performance headroom, more VRAM at 12 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 3060 is the smarter buy by a wide margin. GeForce RTX 3060 is about 119.3% more expensive on MSRP at $329 MSRP versus $150 MSRP, and you are getting 804.0% 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.
