GeForce GTX 645

2010

Why buy it

✅Costs $79 less on MSRP ($150 MSRP vs $229 MSRP).
✅Delivers 53.2% more G3D Mark for each dollar spent, at 12.5 vs 8.2 G3D/$ ($150 MSRP vs $229 MSRP).
✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
❌Very weak future-proofing: 2010-era hardware with 1 GB of VRAM is already obsolete for modern gaming and is hard to recommend today.

Radeon RX 7500

2021

Why buy it

✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).

Quick Answers

So, is GeForce GTX 645 better than Radeon RX 7500?

Yes. GeForce GTX 645 is clearly the better overall GPU here. You are also looking at 1,880 vs 1,873 in G3D Mark. On top of that, GeForce GTX 645 is a 2010 card with no meaningful modern upscaling stack, while Radeon RX 7500 is a 2021 model from an older generation with FSR 3 + AFMF. 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?

Radeon RX 7500 is the more future-proof choice for 2026 and beyond. You are getting a newer 2021 generation instead of 2010, better upscaling support with FSR 3 (2023) instead of no meaningful modern upscaling stack and better frame-generation support with FSR Frame Generation + AFMF (2023) instead of no meaningful modern upscaling stack, and a 7nm process instead of 40nm. 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 can still make sense if you find it at the right price, especially around $150 MSRP. GeForce GTX 645 is still the smarter buy for most people, though, because the raw performance is close while the overall package is cleaner. GeForce GTX 645 is about $79 cheaper on MSRP at $150 MSRP versus $229 MSRP, and you are getting 0.4% higher G3D Mark. Radeon RX 7500 is the newer 2021 card, so it still has a real case if you care more about newer architecture and future-proofing than about squeezing out the strongest gaming value today.

When does Radeon RX 7500 make more sense than GeForce GTX 645?

Yes. Radeon RX 7500 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, future-proofing, and staying closer to $229 MSRP more than squeezing out the extra headroom of GeForce GTX 645. The trade-off is that GeForce GTX 645 currently gives you 0.4% higher G3D Mark. It also leads G3D-per-dollar by 53.2%.

Advanced Features (DLSS/FSR)

A critical advantage for the Radeon RX 7500 is support for FSR Frame Generation + AFMF. This allows it to generate entire frames using AI/Algorithms, essentially doubling the frame rate in CPU-bound scenarios or heavy ray-tracing titles. The GeForce GTX 645 lacks specific hardware/driver support for this native frame generation tier.The GeForce GTX 645 gives access to NVIDIA DLSS (Deep Learning Super Sampling), widely regarding as the superior upscaling method for image quality. The Radeon RX 7500 relies on FSR (FidelityFX Super Resolution), which is capable but generally slightly noisier than DLSS in motion.
