Radeon HD 7870M vs UHD Graphics 32EUs (Alder Lake): 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).
✅UHD Graphics 32EUs (Alder Lake) is already obsolete for modern gaming, so Radeon HD 7870M is the less risky modern option long term.
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

❌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.

UHD Graphics 32EUs (Alder Lake)

Why buy it

✅Draws 15W instead of 45W, a 30W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
❌Older 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 HD 7870M is the faster gaming card right now based on the synthetic data we have. It leads by 0.5% in PassMark G3D (1,507 vs 1,500), which is the best performance signal available in this matchup.

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, the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 28nm process instead of Unknown node, and a newer 2012 generation instead of 0. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon HD 7870M makes the most sense today based on the pricing and value data we have for this matchup.
