I5 vs i7 860 vs i7 920

[snakej]

lol dont hate, i was just bored at work

so i see that the new i5 overclock really well for its price, but before we call it the winner, how does its performance stack up against an overclocked 920 or 860 for instance?

i5 hands down.....

for 200$ and 4.5Ghz on air, what more can you ask for?

If ur gong for multi GPU set up, don't go for the i5 & i7 8xx. Only has only 16x PCi-e lanes..

I got my i7 920 for $200 from microcenter. so for me, it was better than i5.

Many still don't know about the P55 PCI-E handicap. The performance hit is around 6-7% so it's not something to worry about unless you are trying to break a record with a dual GPU setup. On top of that once you overclock the GPU's that 6-7% will decrease as well.

except that microcenter has the i5 for $149

even with the X16 lane... new chipsets are coming out that allow for dual X16 and usage of your PCI/PCI-E4X slots. the fusion chipset claims to run dual X16 with a third in 8X. currently most cards (even the 5870's) dont use the full bandwidth to the cards. if you are going to dual card SLI or crossfire you will not notice a large hit even 8X8 maybe 1-4% over all (perhaps 6% scaling change tops vs the X58). if you are going to do tri or quad sli/crossfire then you will take as much as a 50% hit on the P55 vs the X58 though...

i5 FTW in cost-performance ratio.

I just built an i5 for my office. I didn't want to get into elaborate overclocking but I did some quick and dirty tests just for grins. I got it to 3.9GHz at 72 degrees without worrying about increasing voltages or working with memory settings. Of course if someone worked with it they could do a little better. It will be run 24/7 and I didn't want to run it at high temps like that so for actual use I will step it back down to about 3.5GHz. I had intended to build an i7-920 machine for the same use, but that would have cost at least $300 more. The i7 does have some advantages but considering the cost difference I think the i5-750 has a better ratio of speed to cost.

This is what I built:
i5-750 $200
Gigabyte P55-UD3R $140
G.Skill Ram- 8GB x 1600 $195
total- $535

my other option:
i7-920 $290
ASUS P6T $240
OCZ Ram- 12GB x 1333 $287
total- $817

difference $282

Good information!

----------------------------------------------------------------------------------
It shows that i7-920 system is 52.7% more than i5-750 system!

I F****** love my 920! Well worth the money! I will be overclocking it after xmas when ive got money to buy a better Heatsink!

I'll say this... (having successfully overclocked the i5 @ 6 different settings & stress tested them all a long time..)

The i5 -750 can easially go to 3.612 GHz @ 1600 RAM, if you want to go higher than this, you will need to tweak the ram @ either 1200 or 1066, as it will not stabilize @ 1600 RAM without some danger to your processor.

(Intel warns that voltage over 1.65 v for your ram can damage your i5 processor)

With that being said, I'd say for $150-$200 that's a really nice chip!

However....

The i7 920 can achieve some pretty astounding results, and yes it may cost you like $200-300 more for the set up, the 920 however can reach 4.0 Ghz very easy and at a lot less voltage than the i5, to say the least... (I'm pretty sure the i7 920 OCs over 5 GHz!)

If your serious about getting max Overclock, go i7 - 920, if your on a budget, want a future proof motherboard, then get the i5, it's a great day to choose between 2 great chips! (The 1156 will support 5 more chips comming out!)

The i5 Can reach 4.0 GHz (it's been proven to be stable on 1200 RAM)
You will need a water cooler to reach 4.0 GHz however..

A Fan Cooler, like the Hyper 212+ by Cooler Master can run 3.612 GHz ALL DAY..

I like the i5 because of it's price point...

Can it beat ALL AMD Chips on the market? The answer is simply, YES!

So why would you ever buy AMD again? Beats me...

(BTW, I think 4.3 GHz is the current record on the i5 Processing Overlock Forums so far...)

BOTTOM LINE:

The i5 750 is a better choice.. (money wise)

The i7 920 is a great Over Clocking Beast! (But you will pay for that raw power!)

The other i7s are just wasted shelf space, seriously...

If you really want a great chip, get the Core 2 Duo e8600, now that my friends is a REAL UBER MAD CHIP!
(Over 6GHz! OMG!)
