Iris Pro Graphics P6300 vs Radeon HD 4890: Pros, Cons & Final Verdict

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

Iris Pro Graphics P6300

2014

Why buy it

  • Costs $99 less on MSRP ($150 MSRP vs $249 MSRP).
  • Delivers 69.9% more G3D Mark for each dollar spent, at 10.5 vs 6.2 G3D/$ ($150 MSRP vs $249 MSRP).
  • Draws 15W instead of 190W, a 175W reduction.

Trade-offs

  • Less VRAM, with Unknown vs 2 GB for high-resolution textures and newer games.
  • 2014 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Quick Answers

Which GPU is faster for gaming right now?
Iris Pro Graphics P6300 is the faster gaming card right now based on the synthetic data we have. It leads by 2.3% in PassMark G3D (1,582 vs 1,546), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon HD 4890 is the safer long-term pick for 2026 and beyond. The case is simple: 2 GB vs Unknown of VRAM and the newer upscaling stack, FSR Upscaling / FSR 4 (2025) instead of no meaningful modern upscaling stack. That gives it more room for heavier textures and higher settings over time.
Which GPU is the better buy today?
Iris Pro Graphics P6300 makes the most sense to buy today. It is $99 cheaper on MSRP at $150 vs $249, and it leads G3D-per-dollar by 69.9% (10.5 vs 6.2), so the value case lines up with the gaming result. If you are mainly targeting 1080p, Iris Pro Graphics P6300 is the easier value choice. If you care more about 1080p and some 1440p headroom, Radeon HD 4890 has the stronger long-term case.
