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

Radeon R9 M275X / M375

2014

Why buy it

  • 700% more VRAM for high-resolution textures and newer games (4 GB vs 512 MB).
  • Draws 75W instead of 100W, a 25W reduction.

Trade-offs

  • Lower average FPS than Radeon Ryzen 3 5300U across 50 tracked games in our benchmark data.
  • 2014 hardware with 4 GB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
  • 20% HIGHER MSRP
    $300 MSRPvs$250 MSRP
  • Lower G3D Mark per dollar, at 5.3 vs 6.2 G3D/$ ($300 MSRP vs $250 MSRP).

Radeon Ryzen 3 5300U

2020

Why buy it

  • 104.1% more average FPS across 50 tracked games in our benchmark data.
  • Costs $50 less on MSRP ($250 MSRP vs $300 MSRP).
  • Delivers 17.8% more G3D Mark for each dollar spent, at 6.2 vs 5.3 G3D/$ ($250 MSRP vs $300 MSRP).
  • Radeon R9 M275X / M375 is already obsolete for modern gaming, so Radeon Ryzen 3 5300U is the less risky modern option long term.

Trade-offs

  • Less VRAM, with 512 MB vs 4 GB for high-resolution textures and newer games.
  • Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
  • 33.3% higher power demand at 100W vs 75W.

Quick Answers

Which GPU is faster for gaming right now?
Radeon Ryzen 3 5300U is the faster gaming card right now. In our data, it leads by 104.1% in average FPS across 50 tracked games in our benchmark data.
