I'm looking at the specs on two different CPUs and I can't decide which makes better sense.
I'm not planning to overclock, so that is not a consideration. I will install video cards, so the onboard video is not a consideration. Cake is a consideration...
Candidate 1.
Sandy Bridge Intel Core i7-3820 supports only PCI-e 2.0. memory bandwidth is 51.2GB/s and DMI bandwidth (graphics?) is 5GT/s. Cache is 10MB. CPU frequency is 3.6Ghz
Candidate 2.
Ivy Bridge Intel Core i7-3770 (or the 3770K for a few dollars more) Third gen Core, so less power, and it offers PCI-e 3.0. Memory speeds are the same, memory bandwidth is half that of the previous processor at 25.6 GB/s, cache is 8Mb and DMI bandwidth is the same as the previous. CPU frequency is 3.4Ghz
The performance benchmarks all show the 3770 higher than the 3820.
I don't get it, does the higher speeds and feeds not make it outperform the 3770? What reasons can there be to get the 3820 over the 3770?
And then, of course if I get the 3770, I may as well fork over the $30 extra for the K-model and if I ever want to overclock, I can, right?
