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

Radeon IGP 320M

2019

Why buy it

✅+33.3% higher PassMark G3D performance.
✅RADEON IGP 345M is already obsolete for modern gaming, so Radeon IGP 320M is the less risky modern option long term.
✅More future proof: RDNA 1.0 (2019−2020) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌142.9% higher power demand at 85W vs 35W.

RADEON IGP 345M

2016

Why buy it

✅Draws 35W instead of 85W, a 50W reduction.

Trade-offs

❌Lower PassMark G3D performance (3 vs 4).
❌2016 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers
