Synthetic benchmark performance
Non-gaming benchmark results comparison. The combined score is measured on a 0-100 point scale.
Combined synthetic benchmark score
This is our combined benchmark score. We are regularly improving our combining algorithms, but if you find some perceived inconsistencies, feel free to speak up in comments section, we usually fix problems quickly.
Passmark
This is the most ubiquitous GPU benchmark. It gives the graphics card a thorough evaluation under various types of load, providing four separate benchmarks for Direct3D versions 9, 10, 11 and 12 (the last being done in 4K resolution if possible), and few more tests engaging DirectCompute capabilities.
Gaming performance
Let's see how good the compared graphics cards are for gaming. Particular gaming benchmark results are measured in FPS.
Pros & cons summary
| Performance score | 1.45 | 1.34 |
| Recency | 27 November 2013 | 14 May 2012 |
| Chip lithography | 28 nm | 22 nm |
| Power consumption (TDP) | 15 Watt | 45 Watt |
GT 820M has a 8.2% higher aggregate performance score, an age advantage of 1 year, and 200% lower power consumption.
HD Graphics P4000, on the other hand, has a 27.3% more advanced lithography process.
Given the minimal performance differences, no clear winner can be declared between GeForce GT 820M and HD Graphics P4000.
Be aware that GeForce GT 820M is a notebook card while HD Graphics P4000 is a desktop one.
