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 $100 less on MSRP ($150 MSRP vs $250 MSRP).
✅Delivers 70.5% more G3D Mark for each dollar spent, at 10.5 vs 6.2 G3D/$ ($150 MSRP vs $250 MSRP).
✅Draws 15W instead of 100W, a 85W reduction.

Trade-offs

❌Less VRAM, with Unknown vs 512 MB 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.

Radeon Ryzen 3 5300U

2020

Why buy it

✅100+% more VRAM for high-resolution textures and newer games (512 MB vs Unknown).
✅Iris Pro Graphics P6300 is already obsolete for modern gaming, so Radeon Ryzen 3 5300U is the less risky modern option long term.
✅More future proof: RDNA 1.0 (2019−2020) on 7nm with a newer platform for upcoming games.

Trade-offs

❌Older hardware, 512 MB of VRAM, and weaker feature support mean it will age faster in newer AAA releases.
❌
66.7% HIGHER MSRP
$250 MSRPvs$150 MSRP
❌Lower G3D Mark per dollar, at 6.2 vs 10.5 G3D/$ ($250 MSRP vs $150 MSRP).

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 Ryzen 3 5300U is the safer long-term pick for 2026 and beyond. The case is simple: 512 MB vs Unknown of VRAM, 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 2020 generation instead of 2014. 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 $100 cheaper on MSRP at $150 vs $250, and it leads G3D-per-dollar by 70.5% (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 Ryzen 3 5300U has the stronger long-term case.
