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

GRID P6-4Q

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 2.2 vs 0 G3D/$ ($2,000 MSRP vs Unknown MSRP).
✅Draws 100W instead of 300W, a 200W reduction.

Trade-offs

❌2015 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Instinct MI25 MxGPU

2017

Why buy it

✅More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

❌2017 hardware with 2 GB 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 2.2 G3D/$ (Unknown MSRP vs $2,000 MSRP).
❌200% higher power demand at 300W vs 100W.
