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

Iris Plus Graphics 640

2017

Why buy it

✅Draws 15W instead of 40W, a 25W reduction.
✅More future proof: Generation 9.5 (2016−2020) 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.
❌2017 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon HD 7850M

2012

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (2 GB vs Unknown).
✅Iris Plus Graphics 640 is already obsolete for modern gaming, so Radeon HD 7850M is the less risky modern option long term.

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.
❌166.7% higher power demand at 40W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 7850M is the faster gaming card right now based on the synthetic data we have. It leads by 1.5% in PassMark G3D (1,373 vs 1,353), which is the best performance signal available in this matchup.

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

Radeon HD 7850M is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM and the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon HD 7850M makes the most sense today based on the pricing and value data we have for this matchup.
