Performance - DDR3 Memory read | write
Memory Read test
Obviously we also had to peek at memory bandwidth performance. Now, obviously Intel Bloomfield based Core i7 processors have an advantage here, triple-channel memory. This explains the tremendous amount of read performance for the Core i7 platform. Lynnfield has only two channels available (dual-channel) but being based on the Nehalem design, they are freakishly fast compared to anything with an FSB.
We test at reference 1333 MHz CAS 9:9:9:24 1T And then the overclocked simply ran it at 1850 MHz CAS 8:9:9:24 -- courtesy of OCZ's Lynnfield ready dual channel memory kit.
Memory Write test
The same can be said for the memory write tests. Of course Intel dominates here considering we used 1333 JEDEC timed memory on both platforms. Triple channel performance on Nehalem is just frighteningly good really.
