i5 660 vs i5 661

post #1 of 3
Thread Starter 
Guys, I've just been offered a 661 in exchange for a 760.
I wanted less heat and didn't actually need 4 cores in a HTPC.

What are the real differences between the 661 and the 660 though?

Going through the Intel spec sheets, it seems like the 661 has a higher TDP of 87W versus the 73W TDP on the 660's part despite not having 'embedded features'.
Is that something to worry about? The 760 had a 95W TDP but didn't seem to be going anywhere near that number.

If it helps, the system will not be overclocked. Instead, it will be down-clocked to 2 or 3GHz, so I wonder if the 661 is a smart buy.

EDIT: I hope I'm not shooting myself in the foot by buying a better CPU for a HTPC than one for my daily driver. The DD uses an i3 2100 mated to a Z68 PRO3-M whereas the HTPC is slated to have the i5 661 mated to a P7H55M.

The major difference between the 660 and 661 is the clocking of the integrated GPU. The 660 is @ 733MHz, the 661 is @ 900MHz. There only other difference I could find is that the 660 has "Intel Trusted Execution technology", which the 661 lacks.

Why dont you just disable 2 cores in the 760 and leave it at the base clock? Will reduce the heat a bit, although the 760 doesn't put out much heat in factory mode.
