Radeon IGP 320M

2019

Why buy it

✅+33.3% higher PassMark G3D performance.
✅Radeon IGP 340M is already legacy-tier future-proofing, so Radeon IGP 320M is the less risky modern option long term.
✅Draws 85W instead of 230W, a 145W reduction.

Trade-offs

❌Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.

Radeon IGP 340M

2018

Why buy it

✅Competitive enough if your priority is price, power, or specific feature preference.

Trade-offs

❌Lower PassMark G3D performance (3 vs 4).
❌2018 hardware with 512 MB of VRAM already sits in legacy territory for modern games.
❌170.6% higher power demand at 230W vs 85W.
