Core i7-860 and Core i7-870

Well the LGA1156 i7s may have higher clockspeeds and turbo clockspeeds, bu they might not have as much OC potential being as the higher end silicon is used for 1366 processors. 4 GHz may not be a given with these new chips.
 
You got to look at the whole package cpu,mb and ram and what you do with it and if you going muti gpu's in the future,i would more likely go 920 if i was going muti gpu's and the price wasn't a lot more.

The trouble i have is ii not long brought 2 sticks of ddr3 so if i do go the i7 920 route i have to buy new triple channel memory also which adds more cost but also if i go cheaper way of new i5 or i7 then if it turns out not as good as the i7 920 i will fell disapointed every time i use it.
I dont use it for games just encoding and all iread on here is 920 is best for encoding and i5 wont be as good for encoding so thats out somethink idont wish to buy. But im wondering will the new i7s be as good for encoding as the i7 920.
With no reviews out it makes it a hard Decision of what to get and time is running out as new parts are available from the 8th as you guys know.
 
Do the i7 8xx series processors have Quick Path Interconnect or is it back to the old FSB with them?

EDIT: Seems they don't have QPI so i7 8xx is a bit of a Core 2/Core i7 hybrid, it will be interesting to see if the FSB is a limiting factor under heavy multithreading.

the new i5 CPU will be slower than a 920, due to the fact the 920 has HUGE bandwidth, more RAM and is basicaly a server CPU, if you are rendering or encoding, i can only tell you to get a 920, but make sure the software you use supports multi core or multi threaded CPU's.

when encoding video on my rig it doesnt take too long, about 20mins to do 1 movie, and it hardly stresses the CPU, but if i tell the software to encode 4 movies, it takes about 30mins to do all 4 together and puts about 50-70% load on the CPU.

now if i had a i5 cpu ( i can only speculate) it wont be as quick as my 920, and it wont be able to do as much encoding at the same time, due to the bandwidth and ram.

the i7 8xx series wont do as well in heavy multithreading, it has less bandwidth due to not having the QPI but the old FSB style, QPI provided something like 30gb/s FSB is like 2gb/s thats why.

it will still be better than anything in its price range, thanks to HT and/or Turbo Boost.

Its DMI, not FSB. The general suggestion is it doesn't really matter unless your running dual-quad-core, which would only be an option for an i7 anyway, as i understand it.
Memory controllers are on the chip still, unlike the aging C2D. (How long ago did AMD move the memory controller to the chip while intel was following its P4 dead end)

Thanks for someone who speaks plain english.

Would still be interesting to see clock for clock benchmarks without the i7 8xx "Turbo" mode skewing the results and of course overall overclockability is a big factor.
