About G3D Mark

G3D Mark is a standard benchmark that measures graphics performance in real-world gaming scenarios. It simplifies comparing cards from different brands, where higher scores directly correlate with better fps and smoother gaming experiences.

Iris Pro Graphics P6300 vs Radeon RX Vega 8: 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

  • Delivers 100+% more G3D Mark for each dollar spent, at 10.5 vs 0 G3D/$ ($150 MSRP vs Unknown MSRP).

Trade-offs

  • 2014 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon RX Vega 8

2018

Why buy it

  • Iris Pro Graphics P6300 is already obsolete for modern gaming, so Radeon RX Vega 8 is the less risky modern option long term.
  • More future proof: GCN 5.0 (2017−2020) on 14nm with a newer platform for upcoming games.

Trade-offs

  • 2018 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 2.7% in PassMark G3D (1,582 vs 1,540), which is the best performance signal available in this matchup.
Which GPU is the safer long-term pick for 2026 and beyond?
Radeon RX Vega 8 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 and a newer 2018 generation instead of 2014. That makes it the less risky pick as game demands keep moving.
Which GPU is the better buy today?
Iris Pro Graphics P6300 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Iris Pro Graphics P6300 is the easier value choice. If you care more about 1080p headroom, Radeon RX Vega 8 has the stronger long-term case.
