Intel Core i7 920 vs 860
- Thread starter humbug
- Start date
one is 1366 socket,other is 1156 socket
the 920 has slightly higher qpi bandwidth,other than that they are similar
95w tdp the 860 and 130w tdp the 920
I think the 860 only supports dual channel ram,not triple or dual like the 920 does
920 will hit 4.2ghz,probably the same for the 860

Have owned both of these (still have the 860), the 860 is newer but it doesn't really make a difference (Lynnfield launched the year after Bloomfield). At stock the 860 will perform slightly better, when overclocked they will reach the same performance. This is basically like comparing the i7 3820 and 2700K, the CPU's themselves are pretty much even, its their platform that makes the difference, if you need X79 features and the ability to go 3920K at a later date you go for the 3820, if you needed X58 features and the ability to go hexcore at a later date you went for the 920.
The benefit of the 860 when they were new, was you could get equal performance (better at stock) with a 920 system (using up to 2 GPU's) while paying half as much for the motherboard and as a bonus you could get an 8GB dual channel kit for the same price as a 6GB tri-channel one. If that benefit still holds true with used prices is another matter.

So the 860 is dual channel DDR3 RAM and socket 1156, clock for clock its similar performance to the 920, is that right?
Thats a more sort of normal chip. also socket 1156 Motherboards seem more readily available while 1366 Motherboards are getting rare.
the 920 tri channel will have better bandwidth,
trouble with socket 1156 is the sata3/usb3 robs pcie speed so you wouldn't be able to run 2 16x pcie slots,it would reduce to 16x8x
where as x58/1366 socket can run 2 16x16x

Indeed.
However testing showed you don't actually need that additional bandwidth unless your using a hex core as quads don't bottleneck on dual channel.
Indeed, like I said above if you plan on using multiple GPU's 1366 is the better option, else 1156 will give equal performance for less money.
If i could afford it i would just get a 3770K rig..
The problem is, while i could get a used 920 for £80, which is ok, with the Motherboards being so few people are wanting a bit much for them, and 3 channel RAM is again not cheap and difficult to get a hold of.
The 860 is nice and simple, £80 for the CPU, £60 for the Motherboard and then just some mainstream 2 channel DDR3, job done....
I'm not bothered about USB3, i only have one 7870, with a possible nother for xFire soon. AMD GPU's don't need 16x PCIe's, its not going to make that much diffrence is it?

There's an i7 going for 75 quid on the members market.
Ask Toxic (Who's usually in the MM) if he's got any X58 boards.
There's usually a ton of decent deals for X58 boards.
There's also some Foxconn blood something boards cheap brand new at places (Or at least was)

you could go used z68/2600k?
yh I suppose the 860 is ok,might affect the newer cards with 16x8x but not much tbh,same as pcie3 only accounts for 1% performance atm
good x58 boards to go for are the gigabyte x58a oc or the ud5,or asus p6x58d-e
I have three tri channel ocz reaper kits 1800mhz but id want a fair bit for them tbh
EDIT: don't forget x58 supports dual channel aswell

Will do that thanks
I'm looking at the 2600K and the 2500K as well, but i have to wait a few days for funds and its not going to be much, the newer i5's or i7's might be a bit to much.
Its only tempry until i can't work up the funds for a brand new rig again.
My x6 is dying, its had a hard life.
I'm not going back to AMD unless they can prove some real competitiveness with their CPU's.
the 2600k is a good choice imo
x58 tends to suffer badly from emi/coil whine,i had three boards and everyone suffered from it
no issues at all with z68/z77 boards,i would save a bit more and go z68,you get true sata3 speeds aswell

Time for the Coils to settle in not fix that?
No coil whine here had the ud5 since new.
