See where each GPU makes more sense in practice: raw FPS, VRAM, features, power draw, pricing, and long-term headroom.

GeForce GTX 580

2010

Why buy it

✅10.4% more average FPS across 50 tracked games in our benchmark data.
✅Costs $1 less on MSRP ($499 MSRP vs $500 MSRP).
✅50% more VRAM for high-resolution textures and newer games (3 GB vs 2 GB).

Trade-offs

❌2010 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌62.7% higher power demand at 244W vs 150W.

Radeon Sky 500

2013

Why buy it

✅Draws 150W instead of 244W, a 94W reduction.
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Lower average FPS than GeForce GTX 580 across 50 tracked games in our benchmark data.
❌Less VRAM, with 2 GB vs 3 GB for high-resolution textures and newer games.
❌2013 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?

GeForce GTX 580 is the faster gaming card right now. In our data, it leads by 10.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon Sky 500 instead at 4,723 vs 4,634, so for this question the real-game FPS result matters more than the synthetic split.

Which GPU is the safer long-term pick for 2026 and beyond?

GeForce GTX 580 is the safer long-term pick for 2026 and beyond. The case is simple: 3 GB vs 2 GB of VRAM. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon Sky 500 makes the most sense to buy today. It is $1 more expensive on MSRP at $500 vs $499, and it leads G3D-per-dollar by 1.7% (9.4 vs 9.3), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon Sky 500 is the easier value choice. If you care more about 1080p and some 1440p headroom, GeForce GTX 580 has the stronger long-term case.
