The Gigabyte Z77X-UD5H-WB was fastest in AIDA64'southward read retentiveness bandwidth examination, beating the Asrock Z77 Extreme6 by a couple hundred megabytes per second, while the Extreme6 provided slightly better write performance. The Intel DZ77GA-70K was slower than both, but withal managed to outpace the ECS Z77H2-AX in read performance, while ECS had a considerable edge in writes.

The Gigabyte Z77X-UD5H-WB beat Asrock's lath over again when measuring read performance, but was slightly slower when comparing writes. The Intel DZ77GA-70K was slower than both the Asrock and Gigabyte boards, while the ECS Z77H2-AX was fifty-fifty slower.
