Iris Pro Graphics P6300

2014

Why buy it

✅Draws 15W instead of 35W, a 20W reduction.

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 Vega11

2018

Why buy it

✅Iris Pro Graphics P6300 is already obsolete for modern gaming, so Radeon RX Vega11 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.
❌133.3% higher power demand at 35W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon RX Vega11 is the faster gaming card right now based on the synthetic data we have. It leads by 1.5% in PassMark G3D (1,605 vs 1,582), which is the best performance signal available in this matchup.

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

Radeon RX Vega11 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?

Radeon RX Vega11 makes the most sense to buy today. It is priced the same on MSRP at $150 vs $150, and it leads G3D-per-dollar by 1.5% (10.7 vs 10.5), so the value case lines up with the gaming result.
