Intel Core i5 Performance

[STaRGaZeR]

Yep - at least what Intel says
But I suppose I can't say that...

Pity

[jasonelmore]

I saw where Tweaktown.com stole the OP's content and put it up on there site. LOL

[flopper]

One year from now, thats like 2 years technology development.
and besides, good luck overclocking i5 to 4ghz+

I get a new videocard, before that which will enhance my fps more than any new cpu coming out the next 2 years.


Unless amd pulls a rabbit out of the hat with their new p2

Thanks +2! When or if the NDA is lifted please fill us in.

Deneb will be the new top of the line from AMD, the i5 is a downgrade from what is already out, the i7. That is the difference here.

That's no real difference at all! There was a lot of info on i7 months before its launch as well.

[Nelly]

H'mm wonder if i5 will use the newer low voltage DDR3? wonder if it's safe to use the higher voltage DDR3 2x2gb sticks in dual channel.

There is no reason why i5 would use different memory voltage than i7. If i7 can't take x amount of volts, i5 can't take them.

Sure, I guess that happens only when I die

not correct!

"problem" with i7 is that QPI voltage is connected with DRAM voltage... if you rise DRAM voltage you rise QPI voltage also... i5 doesn't have QPI!

The good thing with i5 is that'll bring true sucssesor to LGA775 platform... LGA13xx will stay only for server/WS market, and LGA1156 (previously LGA1160) will be the mainstream platform... current Bloomfield platform is death end for mainstream desktop just as Socket940 was for AMD... LGA 1156 is the way of the future for intel desktop users...

Thats not true...

LGA1366 will stay for the enthutiasts and SLI/Crossfire users. LGA1156 is basicly for everyone without crossfire/sli. Plus cheap.

[adamsleath]

maximises the appeal for multicard users thats for sure (1366)

[Nedjo]

pff Lindfield's integrated PCIe bridge support 8x/8x PEG 2.0 split and that's sufficient for CFX and SLI! (efectively that's same BW as with 16x/16x PEG1.1, and that's enough for CrossFire and SLi)...

and what will benchmarking of i5 prove is that clock-4-clock it gives same performance as Bloomfield for the less price, alnd since LGA1156 mobos wiil be much more affordable it rise the question of reasoning behind purchase of any futurre Bloomfield CPU and LGA1366 mobo...

First of all far from all Lynnfield CPUs support it. Secondly. Alot of mobo makers wont do 8/8 but just 16. And trichannel still wins alittle bit over dualchannel.

1366 is the choice for multi GPU. Just like people before bought 975x, X38, X48.

[Nedjo]

what are you saying, that some Lynnfields will not have PEG ctrl. with 16 PEG 2.0 lanes in it?

[Shintai]

what are you saying, that some Lynnfields will not have PEG ctrl. with 16 PEG 2.0 lanes in it?

No, but just like P43 vs P45 chipset. One can be divided into 8/8. The other can only be in 16 mode.

[Nedjo]

No, but just like P43 vs P45 chipset. One can be divided into 8/8. The other can only be in 16 mode.

what chipset got to do with the fact that PEG ctr. is inside CPU?

[Shintai]

You can say the same about P43 vs P45. But that doesnt change the fact. Its an example of 2 chips with both 16 lanes for GFX. One can divide into 8/8 the other cant.

Its not exactly rocket science to know its no different on a chipset than ondie on a CPU.

[jasonelmore]

The P43 is just lacking the crossfire controller on the motherboard, not on the chip. The Chip is the same exact chip as the P45. Possibly lower binned tho.

so you're telling that Intel will be selling two kinds of Lynnfield - one capable of splitting the PEG lanes, and other restricted to 16x only?

Just like AMD, MS, nVidia whatever. Its called segmentation and artificial limits.

[Nedjo]

Just like AMD, MS, nVidia whatever. Its called segmentation and artificial limits.

and you think it makes sense to segmentation on the base of enabling / disabling PEG lanes splitting, and not other features, like HT on/off, turbo on/off... etc... is PEG ctr. so critical and complex part of the CPU that Intel needs to create differentiation in CPU lineup on the base of PEG capabilities... yeah right!

for a reminder AMD, NVIDIA, INEL are doing differentiation on the base of harvesting good transistors, and not artificial enabling / disabling features... only Apple is doing that with their DVDRW's capable of writing only 8x on cheaper machines

[Macadamia]

Segmentation should be done on the mobo. Otherwise it would be a complete messup. :/
Intel's smarter than this.

As if 1366 vs 1156 wasn't enough, now you got 1366 with or without SLi, and 1156 with or without SLi, or without MGPU. So no.

[Neuuubeh]

for a reminder AMD, NVIDIA, INEL are doing differentiation on the base of harvesting good transistors, and not artificial enabling / disabling features...

Sorry, but didnt AMD and NVIDIA use to "laserlock" parts of the GPUs, thus producing the low-performance mainstream parts (I cba to look up in which series they did it)?? What about Nvidia having special drivers with opengl overlay optimizations just for the Quadro series, when it works perfectly on the Geforce series? I bet there are more examples :P.

PS I think I might have read your post wrong :p You probably meant "unlike AMD and NVIDIA, INTEL are doing differentiation on the base of harvesting good transistors, and not artificial enabling / disabling features..." :P. Oh well, figures

Hehehehe!

[bowman]

LGA1156, LGA1160.. What a cluster, can't they decide?

Apparently Intel Design and Development tools use the 'LGA1160' socket, now I'm not going to count those pins but still. Is this some outdated site, is Fuad stumbling again?

[savantu]

That's made by the mobo manufacturers , not Intel.
