In October 2008 Intel had a very strong position in the desktop market. The quad core X9770 CPU was, by some way, their fastest desktop CPU available and consumers had to look quite far down the Core 2 range before finding a processor which had any competition from AMD.
Rather than wait for AMD to catch up Intel decided at that point to launch the Core-i7 range of CPUs. Each of the three models released at the time provided exceptional performance, far in excess of anything else available. Once again though Intel were not content for their main competitor to play catch up and in February a new revision of the i7 920 was quietly launched followed by Nehalem EP in April.
Nehalem EP used the same D0 core as that found in the new 920 which left the top performing 965 processor on the older C0 revision. Rather than change the CPU to bring it up to date Intel are once again pushing the market forward with the release of the Core-i7 975 Extreme Edition and we will be putting it through its paces in a selection of mainly real world tests to establish how much of an improvement it is over the existing models in the range.
