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

Iris Graphics 6100

2015

Why buy it

✅Draws 15W instead of 45W, a 30W reduction.

Trade-offs

❌2015 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.

Radeon Vega 3

2021

Why buy it

✅Iris Graphics 6100 is already obsolete for modern gaming, so Radeon Vega 3 is the less risky modern option long term.
✅More future proof: GCN 5.1 (2018−2022) on 7nm with a newer platform for upcoming games.

Trade-offs

❌2021 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌200% higher power demand at 45W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Iris Graphics 6100 is the faster gaming card right now based on the synthetic data we have. It leads by 0.8% in PassMark G3D (899 vs 892), which is the best performance signal available in this matchup.

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

Radeon Vega 3 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 7nm process instead of 14nm, and a newer 2021 generation instead of 2015. That makes it the less risky pick as game demands keep moving.

Which GPU is the better buy today?

Iris Graphics 6100 makes the most sense today based on the pricing and value data we have for this matchup. If you are mainly targeting 1080p, Iris Graphics 6100 is the easier value choice. If you care more about 1080p headroom, Radeon Vega 3 has the stronger long-term case.
