GeForce GTX 645

2010

Why buy it

✅Measures 147mm instead of 168mm, a 21mm shorter card that is more SFF-friendly.

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.
❌
0.7% HIGHER MSRP
$150 MSRPvs$149 MSRP
❌471.4% higher power demand at 200W vs 35W.

Quick Answers

So, is GeForce GTX 645 better than Radeon Pro WX 2100?

Yes, but this is not really about a huge raw performance gap. The broader synthetic picture is also very close at 1,880 vs 1,871 in G3D Mark. The bigger reason to prefer GeForce GTX 645 is the overall package: you are getting no meaningful modern upscaling stack.

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?

GeForce GTX 645 is the smarter buy by a wide margin. GeForce GTX 645 is about 0.7% more expensive on MSRP at $150 MSRP versus $149 MSRP, and you are getting 0.5% higher G3D Mark. Radeon Pro WX 2100 really only makes sense now as a very cheap stopgap or a used-market placeholder.

When does Radeon Pro WX 2100 make more sense than GeForce GTX 645?

Yes. Radeon Pro WX 2100 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 newer architecture, lower power draw (35W vs 200W), and staying closer to $149 MSRP more than squeezing out the extra headroom of GeForce GTX 645. The trade-off is that GeForce GTX 645 currently gives you 0.5% higher G3D Mark. Radeon Pro WX 2100 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.
