How does the i7-930 compare to the x4 965. x4 technically is faster @ 3.4Ghz and both are quad core. However the intel is supposedly better. Why?
It is not really technically faster.
The i7 executes more instructions/work per cycle.
The i7 has, in addition to 4 cores, 4 more hyperthreads which can do additional work. The hyperthreads are about 1/4 the capability of a full core.
The i7 uses the X58 chipset which allows triple channel ram, supports 24gb, and has multiple X16 pci-e slots.
It appears that currently, the i7 can overclock higher.
If you look at tha anand benches, the i7 wins out in most workloads.
What makes the amd processors competitive is their pricing.http://www.anandtech.com/bench/CPU/2
