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

Quadro K420

2014

Why buy it

  • Costs $5 less on MSRP ($150 MSRP vs $155 MSRP).
  • 100% more VRAM for high-resolution textures and newer games (1 GB vs 512 MB).
  • Draws 108W instead of 180W, a 72W reduction.

Trade-offs

  • Lower average FPS than Radeon R7 A10-7800 across 50 tracked games in our benchmark data.
  • 2014 hardware with 1 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon R7 A10-7800

2024

Why buy it

  • 15.6% more average FPS across 50 tracked games in our benchmark data.
  • Better long-term bet: RDNA 3.0 (2022−2026) on 5nm gives it a newer hardware base for upcoming games.
  • More future proof: RDNA 3.0 (2022−2026) on 5nm with a newer platform for upcoming games.

Quick Answers

Which GPU is faster for gaming right now?
Radeon R7 A10-7800 is the faster gaming card right now. In our data, it leads by 15.6% in average FPS across 50 tracked games in our benchmark data and by 1.9% in PassMark G3D (740 vs 726), so the answer here is pretty clean.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon R7 A10-7800 is the safer long-term pick for 2026 and beyond. The case is simple: the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack, a 5nm process instead of 28nm, 60 vs 0 ray-tracing units, and a newer 2024 generation instead of 2014. That gives it the more rounded hardware package for newer games.
Which GPU is the better buy today?
Quadro K420 makes the most sense to buy today. It is $5 cheaper on MSRP at $150 vs $155, and it leads G3D-per-dollar by 1.4% (4.8 vs 4.8), which is enough to swing the recommendation its way. If you are mainly targeting 1080p and some 1440p, Quadro K420 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon R7 A10-7800 has the stronger long-term case.
