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

Radeon HD 2900 XT

2013

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 1.7 vs 0 G3D/$ ($399 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (1 GB vs Unknown).
✅Radeon RX Vega 3 is already obsolete for modern gaming, so Radeon HD 2900 XT is the less risky modern option long term.

Trade-offs

❌Lower average FPS than Radeon RX Vega 3 across 50 tracked games in our benchmark data.
❌2013 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌66.7% higher power demand at 25W vs 15W.

Radeon RX Vega 3

2019

Why buy it

✅40.0% more average FPS across 50 tracked games in our benchmark data.
