Iris Pro Graphics P6300

2014

Why buy it

✅Draws 15W instead of 50W, a 35W 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.
❌
51.5% HIGHER MSRP
$150 MSRPvs$99 MSRP
❌Lower G3D Mark per dollar, at 10.5 vs 16.0 G3D/$ ($150 MSRP vs $99 MSRP).

Radeon 540X

2018

Why buy it

✅Costs $51 less on MSRP ($99 MSRP vs $150 MSRP).
✅Delivers 52.1% more G3D Mark for each dollar spent, at 16.0 vs 10.5 G3D/$ ($99 MSRP vs $150 MSRP).
✅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 540X is the less risky modern option long term.

Trade-offs

❌2018 hardware with 512 MB of VRAM already sits in legacy territory for modern games.
❌233.3% higher power demand at 50W vs 15W.

Quick Answers

Which GPU is faster for gaming right now?

Radeon 540X is the faster gaming card right now based on the synthetic data we have. It leads by 0.4% in PassMark G3D (1,588 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 540X 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, and a newer 2018 generation instead of 2014. That gives it more room for heavier textures and higher settings over time.

Which GPU is the better buy today?

Radeon 540X makes the most sense to buy today. It is $51 cheaper on MSRP at $99 vs $150, and it leads G3D-per-dollar by 52.1% (16.0 vs 10.5), so the value case lines up with the gaming result.
