Motherboard Myth Busting ASUS CROSSHAIR V FORMULA VS GIGABYTE 990FXA-UD5 - THE EFFICIENCY SHOWDOWN ERP: Gigabyte GA- 990FXA UD - $180 | ASUS Crosshair V Formula -$220 Website: http://www.gigabyte.com | http://www.asus.com/ Test Machine • AMD FX 8150 and 1090T CPU • 4GB Corsair Dominator 12800C8 • Asus GTX480 (WHQL 285.62 drivers) • Western Digital 1Tb Green Caviar HDD • Corsair AX1200 PSU • Windows 7 64Bit Pro SP1 fully patched the official press kits containing the CH V board. We ran some benchmarks that would hopefully demonstrate this claimed difference. We performed these at the Stock speeds of our AMD CPUs on a new install of Windows 7 Pro. The main stress points were CPU, RAM and GPU efficiency. ANALYSIS T his is not the typical review you might find in more common websites or magazines. The intention here was to see how efficient the Asus board really is in comparison with Gigabyte's cheaper offering, the UD5 and if there’s some truth to the claimed poor performance of the Crosshair V Formula. The 990FXA-UD5 was one of the boards that had been used by some websites; showing completely different results compared to most reviews using 18 The OverClocker Issue 18 | 2012 LOOK AT THE TABLES BEFORE YOU READ THIS! Time to get cracking, starting with the AMD FX-8150 CPU results. As the Crosshair V Formula was designed with the Zambezi architecture in mind one would expect it to perform well yes? Well, as you can see there's not much between the boards. It's so close that we consider the results to fall within the margin of error. Did I test correctly you may ask? Yes of course as these results you see here represent the 3rd run on the FX CPU and even more on the Crosshair V with several bios updates. The outcome was the same, both boards put out similar numbers with the FX 8150 CPU. It makes me wonder how some publications managed such compelling numbers for their FX-8150 reviews. I am perplexed by the numbers which showed the FX-8150 thrashing the 2700K CPU comprehensively. Looking a little bit deeper into some of the other reviews on these very same websites, I saw testing methods, software and games being altered between each review making it pretty hard to compare hardware reliably. Add to which the award rating was so biased awarding “Must buy”, Gold awards and similarly overrated praises. Conclusion: Thank god for the end user reviews and testing. I also tested both boards with a Phenom II X6 1090T CPU and again
