Application Performance
Using Excel to measure real-world application performance, we again see very little difference between the four Intel H55 motherboards.
Interestingly, despite seeing no real evidence of a performance advantage in previous synthetic and real-world benchmarks, we found that when running compression tests using WinRAR that the Asrock H55M Pro did provide a small performance advantage. This board was a fraction faster than the Gigabyte H55M-UD2H, while the Asus P7H55-M Pro was the slowest board tested.
