We will outline the performance increases that can be obtained from using the Asus X99-A motherboard to overclock our system. Our overclocked processor frequency was 4.5GHz and memory speed was 2400MHz.
As a performance comparison, we have included the overclocked results from two other X99 motherboards. The maximum overclocked configuration achieved with each board was a 4.5GHz processor frequency and 2400MHz memory speed.
Asus' X99-A reacts well to a 900MHz boost in CPU frequency. The board manages a joint-top finish in Cinebench and remains competitive with the MSI offering in 3DMark's Physics test.
Bioshock Infinite performance is where the X99-A really shines. While MSI's X99S MPower dropped its gaming performance with a CPU overclock (a very odd issue that we still do not have a clear explanation for), the Asus board was able to maintain the vast majority of its stock-clocked FPS level.
That frame rate retention opens up a 2.2% performance gap between Asus' board and the competing solutions (although Gigabyte had other, more significant issues).
