Memory Bandwidth Performance

MaxxMem² was used to measure the read and write performance of the Core i5 750 processor which utilizes dual-channel DDR3-1333 memory. The Phenom II X4 965 and Core 2 Quad Q9650 also use dual-channel DDR3-1333 memory, so it's interesting to note that the Core i5 produces a far superior memory bandwidth.

In fact, the Core i5 750 was only slightly slower than the Core i7 920 processor, with a read throughput of 11641MB/s and a write speed of 9493MB/s.

Next we are looking at latency using MaxxMem² and the time it took to benchmark each configuration. Note that these numbers are based on the average of half a dozen test runs. The Intel Core i5 750 is situated right between the Core i7 920 and Phenom II X4 965 processors with a latency of 62.3 nanoseconds, which allowed for a completion time of just 13.1 seconds.

EVEREST Ultimate Edition was also used to measure the memory read and write performance. The picture is the same as before, with the Core i5 showing an obvious advantage over Core 2 Quad and Phenom II X4, while falling behind the Core i7 920.
