Windows 7: i7 860 2.8GHz or i7 920 D0 2.66GHz?

i7 860 2.8GHz or i7 920 D0 2.66GHz?

Getting a new processor for a friend tomorrow , could anyone advise me on which of these 2 is better.

The choice based on his price range is either the Intel Core i7 860 2.8GHz Socket LGA 1156 or the Intel Core i7 920 D0 2.66GHz Socket 1366.

He will be getting a new motherboard and memory at the same time so the socket type is not important.

It WILL be overclocked in the future so please bear that in mind.


Whats the general feeling of these 2 cpu's? Is one better than the other?


Many thanks


Paul.

Could you elaborate on that at all bud?

Like a reason why that one is better.

17 860 supports dual channel memory and the 17 920 triple channel and multiple CPU's if neither of the 17 920's advancements mean anything to your friend the 17 860 is a good performer.

If the reason for this purchase is to overclock, I'm not sure I'd get either. The 860 doesn't have a lot of headroom and the 920 starts to get real hot at 1.35 volts. If forced to chose though I'd say the 920.

If gaming is the primary function, then I'd get the 860, because it has turbo boost. If you know you're getting two video cards, then obviously the 920 is the way to go.

How's that for a completely evasive answer!

Totally agree with what Fumz added, if Overclocking is what your friend is desiring to do the other variable is a mobo that will support this function as some do not and others provide every possible user changes like FSB speed, voltages and etc. IF your friend is a serious gamer, or PhotoShop user that processes large amounts of photos they would certainly benefit from the better i7 CPU's like the i7 975 Extreme and i7 980.

What is his price range for the motherboard/processor/memory?

I too would go for the i7 920 version. The reason for this is the memory interface. Basically, the 860 has dual-channel whereas the 920 has tri-channel memory. Scroll down to Memory Specifications in the links below.

i7 860 Intel® Core™ i7-860 Processor (8M Cache, 2.80 GHz) with SPEC Code(s) SLBJJ

i7 920 Intel® Core™ i7-920 Processor (8M Cache, 2.66 GHz, 4.80 GT/s Intel® QPI) with SPEC Code(s) SLBCH, SLBEJ

Thanks for all the info/advice guys.


Ok the budget for mobo/cpu/mem is a max of 440.

He uses it primarily for gaming.

He would not be looking at crazy overclocking , I would say perhaps max of 3.2ghz if that makes any difference.

I have made up 2 choices for him on ebuyer , let me know what you think of the combo

1

ASUS P7P55D-E P55 Socket 1156 8 Channel Audio ATX.. | Ebuyer.com
Intel Core i7 860 2.8GHz Socket LGA 1156 8MB L3 Cache.. | Ebuyer.com
G-Skill 4GB (2x2GB) DDR3 1600MHz/PC3-12800 Ripjaw.. | Ebuyer.com

2

ASUS P6T SE iX58 Socket 1366 8 Channel Audio ATX.. | Ebuyer.com
Intel Core i7 920 2.66GHz Socket 1366 D0 stepping 8MB.. | Ebuyer.com
Same memory as 1

Cost for either is between 430-440


Tricky decisions eh!

He is coming from a Q6600 with DDR2 memory etc


Cheers

Paul.


Edited to add - Should have said , reason we are ordering from ebuyer is the next day delivery to workplace thing. We are doing the build this weekend and will struggle to get the stuff from elsewhere by then.

If the primary use for the machine is gaming, then you must consider the advantages and disadvantages of hyper-threading.

For all intents and purposes, the i5-750 is identical to the i7-920, with the exception of hyper-threading: the i5 does not have it. However, unlike the i7, the i5 does have Turbo Boost. When 4 cores are in use it runs at 2.8GHz; 2-3 cores, 3.2GHz; 1 core, 3.4GHz. It's very sweet.

In a perfect world, games would be properly coded to take advantage of hyper-threading; however, most, if not all games to date do not. In many cases, you find that you get increased game performance by disabling hyper-threading. If you have to disable it, why pay for it?

Knowing that in advance gives you another option to consider (a less expensive option): i5-750. It has Turbo Boost like the 860, but it has more overclocking headroom. I've found that I really don't even need to OC the i5. There isn't a game out that taxes the cpu.

You could apply the money saved elsewhere.

Having said all that, for sure there are apps that really take advantage of hyper-threading (gaming just isn't one of them), and if your friend uses them, enough to justify the cost, then by all means go for a chip that has hyper-threading.
