Looking at read performance the Asrock P55 Extreme was the slowest of the bunch, while the Gigabyte P55-UD6 was again the fastest by a 4% margin. The next MaxxPI² test looks at CPU cache performance where the results were very much the same for all seven motherboards. The Turbo Mode appears to be just as efficient on the value boards as it is on the more expensive high-end boards. EVEREST Ultimate Edition gives us a second opinion on memory bandwidth performance and the results are even tighter with no more than 200MB/s separating the fastest from the slowest motherboards in either the read or write tests.
