In raw write performance, there's very little between the two sets of memory, whereas in read performance the Corsair is ahead but in copy performance the G.Skill takes the lead. The low latency test doesn't make much difference, but the overclocked memory does in read and write by a few thousand MB/s - this is also due to the increased clock speed of CPU Core and Uncore, increasing the overall performance.

Sisoft Sandra claims Corsair is marginally ahead in an apples to apples latency comparison, but again, the difference is minimal. When we stretched the G.Skill with overclocking and low latency, there are some slight improvements though.
