What make's the i7860 less good then the 920?

post #1 of 9
Thread Starter 
My question is in the title. What's the real difference between these 2 models? is it only the ghz? If that's the case I can just buy the 860 and overclock it to the 920 stock settings and get a 920, right?

it's the chipset and motherboard really, P55 vs X58. they are both good cpu's and could do anything you needed. one uses double channel and one uses triple channel ram and that's a wash.

Both are pretty much equal... But the x58 chipset is superior

I have the 860 and Im very happy with it. I would have liked to go to the x58 simply cuss of the full bandwidth of the pci lanes but for budget reasons I stayed with the 1156.

My sig rig is my main pc, lovin' it

The X58 chipset allows dual and triple channel memory while the P55 only allows dual. X58 also has more bandwidth allotted to PCI-E slots and allows x16/x16 configurations of graphics cards while P55 can only do this with a bridge chip like the Nvidia NF200.

The most significant difference, in my opinion, is that the i7 920 usually clocks higher with lower voltage.

However, Lynnfield's (i5 700 and i7 800) memory controller is superior to Nehalem (45nm i7 900 chips) in its ability to push memory better. It can push memory to speeds in excess of 2400MHz while Nehalem struggles past 2000MHz.

Really though, if you're looking towards 1156 systems, I'd recommend the 1155 route instead. Sandy Bridge chips are significantly faster and are more power efficient.

They're not as fun to overclock, but they do clock much further (most are finding 4.7GHz+ to be easy to stabilize).
