Intel Core i5 Benchmarked

[V3NOM]

hang on jimmysmitty... i thought the lynnfields didn't connect to the mobo with QPI.

Seems utterly pointless, is just going to confuse buyers even more. Whts the point to it? its not as good as i7 and is less expendable. Why would you buy it to then decided a yr later tht u want to add another gfx card to it or upgrade it to a newer and better chip. So you have to replace the board cpu and memory, who would want to do that.
Any idea on a price for them yet?

TBH it just looks like somethin to compete with the new phenom 2 chips.

 

[amdfangirl]

Well it depends. Core 2 Quads are still mighty fast against Phenom II's.

 

[cjl]

Wow, looks like intel is bending over its customers once again.
Charging out the buthole for the X58 then coming out with something better and cheaper a couple months later.
With Newegg offering 3ghz Denebs with a 760GX mobo that uses DDR2 for less than the price of just a i7 920, I guess Intel needs this.

Better?

i5 is intentionally lower end than i7 (hence the name) It replaces current C2Q CPUs, not the i7. Intel is keeping the i7 as the high end part, and the i5 will be more of the mainstream/midrange part. It will be cheaper, yes, but not better.

Its like the Duo/Quad debate: Clock for clock, they are about the same, its just what the clocks are set too...

Here are the questions:
1: Will the i5 platform support SLI
2: Will the i7 platform recieve the same lifespan as the i7 platform
3: What will the i5 clocks be, and will it bottleneck SLI/CF setups?

This goes back to my theory that i7/i5 is just a stepping stone to Sandy Bridge in 2011-2012.

 

[cjl]

2011-2012? Sandy Bridge is scheduled for 2010, after Westmere near the end of 2009.

I'm a pessimist. Everything that can go wrong in development probably will. 😛

 

[amdfangirl]

I'm more of the "prove it" type.

 

[JAYDEEJOHN]

i5 will bottleneck cf/sli. 8x lanes arent anough for whats coming, period. This helps LRB in a way also, unless you want uber graphics, use LRB and i5 instead. We really need competition, dont we?

 

[amdfangirl]

soon it'll be 32x... that's how stuff advances in computing tech.

 

[JAYDEEJOHN]

Exactly, and being stuck at 8x isnt a good thing, as youd need an entire new rig just for that. Im begining to think maybe Intel has divided up its lineup too much, hopefully not, but as enthusiasts, it may have just gotten even more expensive to get more for less

 

[JAYDEEJOHN]

Before I get tarred and feathered for my previous post, let me explain. While the average Joe doesnt need encoding,tri channel etc, and he also doesnt use sli/cf, but he games, i5 is a fine solution.

But, as enthusiasts, alot of us have P2's or Q6600's and are running cf/sli, and receive the benefits of both cpu and gpu's in their rigs at an affordably decent price. This may have changed for us, and weve been bimped up to
interprise class, whether we want to be or not

 

[V3NOM]

Actually no. The extra pins on the Core i7 CPUs is because of the 192bit Tri Channel DDR3 conroller. Thats really all there is to it. So I doubt it will connect to differently to the point that it would stop a mobo maker from making a cheaper LGA1366 mobo with the P55.



Actually from what I have read Westmere (the 32nm die shrink of Nehalem) is supposed to use the same LGA1366. Haven't heard if they will use LGA1160, Lynnfield, but if they make dual channel 32nm CPUs I wouldn't doubt it would work since its just like AMD now with the IMC.

Only thing I can forsee needing a new socket is if they add a memory channel or when DDR4 comes out (2011 is the set year for it) IF it needs more pins but considering they made DDR2 and DDR3 use the same amoung of pins (just different layout) I doubt it would need a new socket, it should just use less voltage at higher speeds like DDR3 does.

mmm, but it will. the X58 northbridge controls graphics. the P55 northbridge doesn't. the core i5 controls the graphics directly. so therefore, they cant just slap an i7 onto a P55 - because nothing will be talking to the graphics LOL!

Yep. In fact, the i5 also won't have a QPI link at all IIRC, so the way it connects to the board is completely different.

Um PCIe 2.0 8x is the same speed as PCIe 1.1 16x. And in tests it has been shown that most GPUs, even the high end newer ones, don't see a drop in performance until it drops to about PCIe 1.1 4x which is equivalent to PCIe 2.0 2x. So dual PCIe 8x will not bottleneck CF/SLI. Maybe a Quad CFX/Tri SLI but standard SLI/CF will be fine.

Exactly, and being stuck at 8x isnt a good thing, as youd need an entire new rig just for that. Im begining to think maybe Intel has divided up its lineup too much, hopefully not, but as enthusiasts, it may have just gotten even more expensive to get more for less

No it is fine. Hell PCIe 1.1 has hardly been saturated let alone PCIe 2.0. Hell AGP 8x was not ever fully saturated when PCIe was introduced which is what amazes me. Every time a new graphics tech comes along the old one was barely being utilized. What they need to do is focus on getting rid of the biggest bottleneck, the HDD.

Maybe. You never know. I was guessing before any of the real info had been released. Not much to go by until Intel/AMD relases official specs.

Yep. In fact, the i5 also won't have a QPI link at all IIRC, so the way it connects to the board is completely different.

It will have a IMC but will still connect to the rest of the mobo through the chipset instead of the QPI. The X58 chipset just controls the graphics mainly but Core i7 itself connects to everything else on its own. Core i5 will still rely on the chipset. Which in the end is not that bad. What was bad was the MC being on the chipset.

 

[V3NOM]

...yeah i do actually. P55 is 1160 and that is fact. and as i said before, if P55 is 1160 exclusive, you can't stick an i7 in it. same way you cant stick an i5 in an X58.

 

[JAYDEEJOHN]

i5, or what we used to think of i5, or lynnfield, if it has HT, its i7 now, if it doesnt, which is only the lowest Lynnefield, then its i5

 

[Reynod]

What happened to i6?

Is i8 going to be power hungry as the name suggests?

Can someone confirm the i5 socket please? I am a little confused.

The benchies suggest a great little machine ... I could upgrade all of the kids X2's.

 

[JAYDEEJOHN]

i8 attempts at resuscitation were ended after Intel realized the couldnt feed any info into it, and just kept getting Intel bluish screens of death, with the words, no, thanks on it

 

[Wisecracker]

Could the 'x8' lanes on s1156 be PCIe Gen3 ?

 

[nightsilencer]

Why move already to PCI-e 3.0?

PCI-E 2.0 hasn't even been close to being maxed out.

Hell, I think even PCi-E 1.0 hardly is.

I don't disagree ...

But the new AMD sb800 south bridge is rumored to have PCIe 3.0 support - it's supposed to be out in Q309.

And yah know how those boys like to compete 😗

 

[JAYDEEJOHN]

IF it did have PCI-3, then itd be as good as i7 up to 2 slot configs, which is still a quad setup if you wanted to go that way

 

[B-Unit]

Last PCI-E 1 test I saw was for the 3870x2, so its pretty dated. There was an update sometime later testing PCI-E 2, and IIRC at that time the x4 2.0 links were as slow as you wanted to go.

At this point in the game, Im guessing that 1.0 x16/2.0 x8 are pretty close to saturated with the likes of GTX295 and 4870X2.

 

[JAYDEEJOHN]

They figure next gen top cards will surpass it, meaning it could be possible to have saturation with a x2 card on a single slot, but that may be still a stretch. The rumored BW is more than doubled, so maybe in certain games with certain cards we could see it
