See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.
GeForce GTX 645
2010Why 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
- ❌Lower average FPS than Radeon RX 7500 across 50 tracked games in our benchmark data.
- ❌No equivalent frame-generation stack like FSR Frame Generation + AFMF (2023).
- ❌2010 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
Radeon RX 7500
2021Why buy it
- ✅43.8% more average FPS across 50 tracked games in our benchmark data.
- ✅Access to a newer frame-generation stack with FSR Frame Generation + AFMF (2023).
- ✅Better long-term bet: RDNA 2.0 (2020−2025) on 7nm gives it a newer hardware base for upcoming games.
Trade-offs
- ❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
- ❌52.7% HIGHER MSRP$229 MSRPvs$150 MSRP
- ❌Lower G3D Mark per dollar, at 8.2 vs 12.5 G3D/$ ($229 MSRP vs $150 MSRP).
