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

FirePro V3900

2011

Why buy it

✅Costs $1 less on MSRP ($119 MSRP vs $120 MSRP).
✅100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).

Trade-offs

❌2011 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌100% higher power demand at 150W vs 75W.

Radeon R7 M340

2015

Why buy it

✅Draws 75W instead of 150W, a 75W reduction.
✅More future proof: GCN 1.0 (2012−2020) on 28nm with a newer platform for upcoming games.

Trade-offs

❌Less VRAM, with 512 MB vs 1 GB for high-resolution textures and newer games.
❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
