Radeon Pro V520 MxGPU

2018

Why buy it

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

Trade-offs

❌Lower average FPS than RTX A4000H across 50 tracked games in our benchmark data.
❌Older hardware, 8 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌Lower G3D Mark per dollar, at 0 vs 11.8 G3D/$ (Unknown MSRP vs $1,000 MSRP).
❌114.3% higher power demand at 300W vs 140W.
❌10.8% longer card at 267mm vs 241mm.

RTX A4000H

2021

Why buy it

✅22.8% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 11.8 vs 0 G3D/$ ($1,000 MSRP vs Unknown MSRP).
✅Better long-term bet: Ampere (2020−2025) on 8nm gives it a newer hardware base for upcoming games.
