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

✅23.4% more average FPS across 50 tracked games in our benchmark data.
✅Delivers 100+% more G3D Mark for each dollar spent, at 5.6 vs 0 G3D/$ ($999 MSRP vs Unknown MSRP).

Trade-offs

❌Less VRAM, with 3 GB vs 4 GB for high-resolution textures and newer games.
❌2013 hardware with 3 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌341.2% higher power demand at 375W vs 85W.

Radeon Pro 5300M

2019

Why buy it

✅33.3% more VRAM for high-resolution textures and newer games (4 GB vs 3 GB).
✅Radeon HD 7990 is already obsolete for modern gaming, so Radeon Pro 5300M is the less risky modern option long term.
✅Draws 85W instead of 375W, a 290W reduction.

Trade-offs

❌Lower average FPS than Radeon HD 7990 across 50 tracked games in our benchmark data.
❌Older hardware, 4 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌Lower G3D Mark per dollar, at 0 vs 5.6 G3D/$ (Unknown MSRP vs $999 MSRP).

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 23.4% in average FPS across 50 tracked games in our benchmark data. PassMark G3D leans toward Radeon Pro 5300M instead at 5,853 vs 5,566, so for this question the real-game FPS result matters more than the synthetic split.

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

Radeon Pro 5300M is the safer long-term pick for 2026 and beyond. The case is simple: 4 GB vs 3 GB of VRAM, a 7nm process instead of 28nm, and a newer 2019 generation instead of 2013. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon HD 7990 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p and some 1440p, Radeon HD 7990 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon Pro 5300M has the stronger long-term case.
