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 100W, a 85W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB for high-resolution textures and newer games.
❌2015 hardware with Unknown of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌Lower G3D Mark per dollar, at 0 vs 12.6 G3D/$ (Unknown MSRP vs $69 MSRP).

Radeon R7 G

2015

Why buy it

✅Delivers 100+% more G3D Mark for each dollar spent, at 12.6 vs 0 G3D/$ ($69 MSRP vs Unknown MSRP).
✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Iris Graphics 6100 is already obsolete for modern gaming, so Radeon R7 G is the less risky modern option long term.

Trade-offs

❌2015 hardware with 512 MB of VRAM is already well past its comfortable zone for modern gaming, so it is hard to recommend now.
❌566.7% higher power demand at 100W 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 3.3% in PassMark G3D (899 vs 870), which is the best performance signal available in this matchup.

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

Radeon R7 G is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB 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?

Radeon R7 G makes the most sense today based on the pricing and value data we have for this matchup. Iris Graphics 6100 still makes more sense if max raw gaming performance matters more than value.
