I spent about a week with the Biostar TZ77XE4 before beginning my performance testing, running various configurations and CPUs, and checking hardware compatibility. I verified our power consumption numbers using various different power supplies, and played many hours of online gaming with some members of the TPU community to get an overall feel for the board and to verify stability. Once completed, I tore down the system, mounted our Noctua cooler and put the board through the paces.
SuperPi
SuperPI serves as our memory-focused benchmark, being highly single-threaded. The Biostar TX77XE4 almost matched the ASUS Maximus V Gene here, a big surprise considering that the ASUS board had a much higher overal CPU frequency!
wPrime
wPrime is much more CPU-focused, but memory plays its role as well. In this test, the numbers were much closer to what I expected, with the Biostar TX77XE4 hanging just behind the G1.Sniper M3.
WinRAR
Part of our motherboard benchmarking suite is the built-in benchmark that is part of the WinRAR software suite. In this test, the Biostar TX77XE4 put up good numbers, again just behind the G1.Sniper M3.
AIDA64
We employed AIDA64's memory bench to highlight memory bandwidth. We isolate the write performance metric as it serves as a good indicator of overall memory performance. Here the Biostar TX77XE4 performed exactly as expected, hanging out right along with all the other tested Intel Z77 Epxress products.
HandBrake Encoding
Handbrake is used for encoding testing, and provided results much similar to the previous benchmarks, with the Biostar TX77XE4 just a bit behind the ASUS Maximus V Gene, but at the same time, beating all other Intel Z77 Express results.
CineBench Encoding
In Cinebench, the Biostar TX77XE4 showed great 3D efficiency, and in CPU performance, again we find it on top for Z77 boards using the default Intel profile. Nice job, Biostar!
