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

Iris Plus Graphics 645

2019

Why buy it

✅Draws 15W instead of 75W, a 60W 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 512 MB for high-resolution textures and newer games.
❌2019 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 10.9 G3D/$ (Unknown MSRP vs $130 MSRP).

Radeon R7 M370

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 10.9 vs 0 G3D/$ ($130 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Iris Plus Graphics 645 is already obsolete for modern gaming, so Radeon R7 M370 is the less risky modern option long term.

Trade-offs

❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌400% higher power demand at 75W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Iris Plus Graphics 645 is the faster gaming card right now based on the synthetic data we have. It leads by 2.3% in PassMark G3D (1,450 vs 1,418), which is the best performance signal available in this matchup.

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

Radeon R7 M370 is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB 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.
