Intel Core i7-870 Lynnfield Processor
SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility capable of benchmarking the performance of individual components inside a PC. Each of the benchmarks below were run a total of five times with the highest and lowest scores being discarded and an average being calculated from the remaining three.
Everest is in many ways similar to Sisoft Sandra. Focusing mainly on software and hardware information reporting, Everest also comes with a benchmark utility suitable for testing the read, write and latency performance of the memory subsystem. Each of these benchmarks were performed a total of 5 times with the highest and lowest scores being discarded and an average calculated from the remaining three.
As expected, the dual channel memory controller of the i7-870 simply pales in comparison to the might of the triple channel controller of the i7-920. How much you desire memory performance will depends greatly on your choice of application but as we have shown in previous reviews, the sweet spot appears to be 6GB for most tasks with only large image processing require the huge amounts of bandwidth the i7-9xx series afford. We will shortly be reviewing an 8GB kit for the P55 chipset soon so it will be interesting to see exactly how this compares.
