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

Radeon HD 7800-serie

2012

Why buy it

✅Costs $101 less on MSRP ($349 MSRP vs $450 MSRP).
✅Delivers 23% more G3D Mark for each dollar spent, at 11.5 vs 9.4 G3D/$ ($349 MSRP vs $450 MSRP).
✅Draws 200W instead of 250W, a 50W reduction.

Trade-offs

❌Lower average FPS than Radeon Ryzen 7 6800U across 50 tracked games in our benchmark data.
❌2012 hardware with 2 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Ryzen 7 6800U

2020

Why buy it

✅68.5% more average FPS across 50 tracked games in our benchmark data.
✅Radeon HD 7800-serie is already obsolete for modern gaming, so Radeon Ryzen 7 6800U is the less risky modern option long term.
✅More future proof: RDNA 2.0 (2020−2025) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Older hardware, 2 GB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌
28.9% HIGHER MSRP
$450 MSRPvs$349 MSRP
❌Lower G3D Mark per dollar, at 9.4 vs 11.5 G3D/$ ($450 MSRP vs $349 MSRP).

Quick Answers

Which GPU is faster for gaming right now?

Radeon Ryzen 7 6800U is the faster gaming card right now. In our data, it leads by 68.5% in average FPS across 50 tracked games in our benchmark data and by 4.9% in PassMark G3D (4,225 vs 4,029), so the answer here is pretty clean.

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

Radeon Ryzen 7 6800U is the safer long-term pick for 2026 and beyond. The case is simple: a 7nm process instead of 28nm, 60 vs 0 ray-tracing units, and a newer 2020 generation instead of 2012. That gives it the more rounded hardware package for newer games.

Which GPU is the better buy today?

Radeon HD 7800-serie makes the most sense to buy today. It is $101 cheaper on MSRP at $349 vs $450, and it leads G3D-per-dollar by 23% (11.5 vs 9.4), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Radeon HD 7800-serie is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon Ryzen 7 6800U has the stronger long-term case.
