GeForce GTX 645

2010

Why buy it

✅Costs $69 less on MSRP ($150 MSRP vs $219 MSRP).
✅Delivers 45.5% more G3D Mark for each dollar spent, at 12.5 vs 8.6 G3D/$ ($150 MSRP vs $219 MSRP).

Trade-offs

❌Less VRAM, with 1 GB vs 2 GB for high-resolution textures and newer games.
❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.
❌263.6% higher power demand at 200W vs 55W.

Radeon R7 450

2016

Why buy it

✅100% more VRAM for high-resolution textures and newer games (2 GB vs 1 GB).
✅Draws 55W instead of 200W, a 145W reduction.
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Quick Answers

So, is Radeon R7 450 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 1,887 in G3D Mark. The bigger reason to prefer Radeon R7 450 is the overall package: you are getting a newer generation, FSR upscaling, plus much lower power draw (55W vs 200W).

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

GeForce GTX 645 is the more future-proof choice for 2026 and beyond. You are getting the stronger feature stack with no meaningful modern upscaling stack instead of FSR upscaling. 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 R7 450 is the smarter buy by a wide margin. Radeon R7 450 is about 46.0% more expensive on MSRP at $219 MSRP versus $150 MSRP, and you are getting 0.4% higher G3D Mark. GeForce GTX 645 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does GeForce GTX 645 make more sense than Radeon R7 450?

Yes. GeForce GTX 645 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 future-proofing and staying closer to $150 MSRP more than squeezing out the extra headroom of Radeon R7 450. The trade-off is that Radeon R7 450 currently gives you 0.4% higher G3D Mark. GeForce GTX 645 still holds the G3D-per-dollar lead, so the performance win comes with a real value premium.

Games Benchmarks

Real-world benchmarks and performance projections based on comprehensive hardware analysis and comparative metrics. Values represent expected performance on High/Ultra settings at 1080p, 1440p, and 4K. Modeled using a Ryzen 7 9800X3D reference profile to minimize specific CPU bottlenecks.

Note: Performance behavior can vary per game. Specific architectures may perform better or worse depending on game engine optimizations and API implementation.
