Radeon HD 7870M vs Radeon RX Vega 8: Pros, Cons & Final Verdict

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

Radeon HD 7870M

2012

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
✅Radeon RX Vega 8 is already obsolete for modern gaming, so Radeon HD 7870M is the less risky modern option long term.

Trade-offs

❌Lower average FPS than Radeon RX Vega 8 across 50 tracked games in our benchmark data.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌200% higher power demand at 45W vs 15W.

Radeon RX Vega 8

2018

Why buy it

✅27.5% more average FPS across 50 tracked games in our benchmark data.
✅Draws 15W instead of 45W, a 30W reduction.
✅More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
❌2018 hardware with Unknown 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 RX Vega 8 is the faster gaming card right now. In our data, it leads by 27.5% in average FPS across 50 tracked games in our benchmark data and by 2.2% in PassMark G3D (1,540 vs 1,507), so the answer here is pretty clean.

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

Radeon HD 7870M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon RX Vega 8 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Radeon RX Vega 8 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon HD 7870M has the stronger long-term case.
