Core i7 in laptops?

Any news on when Intel's new processors are going to show up in laptops?

 

This coming May for the Clevo D900F! Nothing else over the horizon yet~

 

It sure is May... unless something "unexpected" happens and they decide to push it further >.>

 

Those laptops will be HUGE. i7 sucks a lot of power and runs really hot.

 

Doubt it'll be any much hotter than current quadcore o.o I think...

 

i7 bah, two socket F processors are faster
Plus its all really glorified, its 4 cores and 4 imaginary cores. Some people call it an 8 core processor. It is not, it is a quad core. In rendering 4 regions can be rendered at the same time, not 8.

Core i7's are 130 watt processors, so they run much hotter than a standard laptop cpu. Even the mobile quads are only 45 watt

All it is a way of making each core handle its tasks more efficiently. Hyper threading is proven to work. I remember running benchmarks with it on and off on my old 3.2 presscott.

I cant wait till we see 8 core chips with hyperthreading support. 16 virtual cores would be sweet to see in the task manager...or plop 2 in a dual socket motherboard and be able to cure cancer in a minute

 

And I assume two socket F can be put in laptops with less power and thermals than single desktop i7??

No one ever said its 8 cores. But wait till the Nehalem server benchmarks come out. These CPUs will match/beat double socket count Harpertown and Shanghai.

 

These CPUs run REALLY FAST. If you use software that is multithreaded, it makes a huge boost. Real world difference between my i7 Desktop and T400 is about 15x when using GCC.

 

Had you gotten nvidia cardsand used them for the cause in addition to the i7 processor im sure you would see 100x if not more increase.

But yes, the i7 is FAST and can not be touched by anything at the moment.

I want to build one, really really bad.

 

I dont know what GCC is, but if you want 4 cores to be as fast as 8 cores, the 4 core processor needs to be 2x as powerful as an 8 core machine to get the job done in the same time. Intel may be leading at the moment in single cpu processing, but when compared to a multi processor setup, and i7 doesnt look all that hot anymore.

And for the record two 2347HE's are more powerful than even the fastest overclocked i7, and both 2347's used a combined power of 110watts, which is less than a single i7. Unfortunately you arent getting a dual socket F laptop ever, unless you build one like myself.

I only mentioned the not 8 cores thing because their was so much hype about it being an 8 core laptop in the D900F thread a few weeks back.

GCC is the GNU C/C++ Compiler. So far, it runs great with Core 2 optimizations and SSE4.2.

Also, GPGPU wouldn't really help compiling, as it really only handles vectors.

Do you have any pics of that laptop you built?

 

It still needs a shell. I have custom cooling ducts, but thats about it. Apparently it is hard to come by a TIG welder which can do 3/8" steel.

I really need to find 1/8" panels, it would be much more practical

K-TRON

 

This I want to see.

 

Are you kidding me?? And not Shanghai but 2347 Barcelona running at measly 1.9GHz?? You are basing off PC applications that have such horrible MT scaling that 8 CPUs give 20% increase but since you mention Opterons its different.

That's why the 2P Nehalem Xeons beat Quad Opteron 8360 by in server apps like SAP, SpecCPU and such right?

People are greatly underestimating Nehalem's potential for servers.

 

nehalem is awesome and much faster f.e. in rendering than current quadcores. k-tron, you're wrong. look at benchmarks. sure, the hyperthreading is not like having 8 cores, but it helps to up the performance by up to 30%.

but of course, two nehalem would be even better

 

Oh I know the i7 completely beats any quad core AMD has, that I do no dispute. But in rendering a core i7 940 takes a good time longer to render the same file in V-RAY than my 8 core 2347 setup.
I have done real life tests and an 8 core is indeed faster than a single i7. If the i7 was faster I would have built a system around it, but in this case its not.
I dont know if their is any bias inflicted from the software I run, but I see V-RAY as a decent way to show real life performance. It is not a synthetic benchmark.

K-TRON

 

Well, keep in mind that if we're talking about a mobile version of the i7, it won't really be able to touch your setup to begin with. I'll be able to give you some real performance metrics on how the top of the line desktop i7 handles once all my components come in. But you're completely right, a single processor solution can't expect to come close to a dual processor solution unless it is twice as fast or the application in question isn't written to support two physical processors (which would be incredibly rare these days).

 

Ditto on that. If someone wants a benchmark ran, I'll see what I can do.

Also, I don't think the topic is about mobile derivatives of Nehalem, its mostly about current gen Bloomfields in a laptop.

@IntelUser: K-TRON wasn't talking about 2P Gainestown vs. 2P Barcelona, he was talking about 1x Bloomfield vs. 2x Barcelona.

 

is there a mobile version of core i7 coming out?

 

There will be 95w lynnfield cpus released around Q3 of this year. They are even expecting 65W quad cores early next year.

On mobile side clarksfield is supposedly 55W part.

 

The reason i7's aren't seeing much use atm is because there aren't many programs which make propper use of the unique way they work. Once/if it gets widely adopted the huge performance of those monsters will become apparent. The software industry is barely getting to grips with quad cores let alone i7's, give it some time and it will eventualy win

 

No, there are laptops that will use the desktop version, but the mobile version of Nehalem will be called Core i5 or Core i3. It features quad core Clarksfield and dual core Arrandale (cpu with gpu connected).

Read above. The thing is the 2347HE is a 1.9GHz version. Most well threaded rendering benchmarks the single Core i7 will beat 2P Barcelona.

 

Dont know if anyone else is mentioning this, but at this point in time, that Core i7 in the Clevo is a desktop chip in a laptop. Actual "mobile" i7's for the mainstream crowd look to be coming out at the end of this year, or very possibly push back to next year because of the supposedly bad economy.

Based on readings of the couple of posts above me some stuff that I read in passing a couple of days ago seems correct. While I never heard that there would never be any core i7 mobile, I did read that core i5 was definite (since some HP? or Mac? - like I said I read it in passing - is already planned to be the first mobile core i5). Who knows with all these crazy names Intel comes up with. There's probably some of this news on Intels updated roadmap, but I havent checked it out anytime recently.
