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

Radeon HD 7990

2013

Why buy it

✅21.2% more average FPS across 50 tracked games in our benchmark data.
✅50% more VRAM for high-resolution textures and newer games (3 GB vs 2 GB).

Trade-offs

❌2013 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌
399.5% HIGHER MSRP
$999 MSRPvs$200 MSRP
❌Lower G3D Mark per dollar, at 5.6 vs 27.8 G3D/$ ($999 MSRP vs $200 MSRP).
❌1400% higher power demand at 375W vs 25W.

Radeon PRO W6300

2022

Why buy it

✅Costs $799 less on MSRP ($200 MSRP vs $999 MSRP).
✅Delivers 399% more G3D Mark for each dollar spent, at 27.8 vs 5.6 G3D/$ ($200 MSRP vs $999 MSRP).
✅Better long-term bet: RDNA 2.0 (2020−2025) on 6nm gives it a newer hardware base for upcoming games.
✅Draws 25W instead of 375W, a 350W reduction.

Trade-offs

❌Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.

Quick Answers

Which GPU is faster for gaming right now?

Radeon HD 7990 is the faster gaming card right now. In our data, it leads by 21.2% in average FPS across 50 tracked games in our benchmark data and by 0.1% in PassMark G3D (5,566 vs 5,560), so the answer here is pretty clean.

Which GPU is the safer long-term pick for 2026 and beyond?

Radeon PRO W6300 is the safer long-term pick for 2026 and beyond. The case is simple: a 6nm process instead of 28nm, 12 vs 0 ray-tracing units, and a newer 2022 generation instead of 2013. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon PRO W6300 makes the most sense to buy today. It is $799 cheaper on MSRP at $200 vs $999, and it leads G3D-per-dollar by 399% (27.8 vs 5.6), which is enough to swing the recommendation its way. Radeon HD 7990 still makes more sense if max raw gaming performance matters more than value.
