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

Radeon HD 6870

2010

Why buy it

✅59.0% more average FPS across 50 tracked games in our benchmark data.

Trade-offs

❌Less VRAM, with 2 GB vs 4 GB for high-resolution textures and newer games.
❌No equivalent frame-generation stack like FSR Frame Generation (2023).
❌2010 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
141.4% HIGHER MSRP
$239 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 9.2 vs 21.6 G3D/$ ($239 MSRP vs $99 MSRP).

Radeon RX 540

2017

Why buy it

✅Costs $140 less on MSRP ($99 MSRP vs $239 MSRP).
✅Delivers 133.5% more G3D Mark for each dollar spent, at 21.6 vs 9.2 G3D/$ ($99 MSRP vs $239 MSRP).
✅Access to a newer frame-generation stack with FSR Frame Generation (2023).
✅100% more VRAM for high-resolution textures and newer games (4 GB vs 2 GB).
✅Radeon HD 6870 is already obsolete for modern gaming, so Radeon RX 540 is the less risky modern option long term.

Trade-offs

❌Lower average FPS than Radeon HD 6870 across 50 tracked games in our benchmark data.
❌2017 hardware with 4 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?

Radeon HD 6870 is the faster gaming card right now. In our data, it leads by 59.0% in average FPS across 50 tracked games in our benchmark data and by 3.4% in PassMark G3D (2,206 vs 2,134), so the answer here is pretty clean.

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

Radeon RX 540 is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 2 GB of VRAM, native frame generation with FSR Frame Generation (2023), while Radeon HD 6870 has no comparable frame-generation support, a 14nm process instead of 40nm, and a newer 2017 generation instead of 2010. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX 540 makes the most sense to buy today. It is $140 cheaper on MSRP at $99 vs $239, and it leads G3D-per-dollar by 133.5% (21.6 vs 9.2), which is enough to swing the recommendation its way. Radeon HD 6870 still makes more sense if max raw gaming performance matters more than value.
