New 2012 Models Speculation Thread - PxxxEM Series (P151EM, P150EM, P170EM)

i thought 660 and 680 are keplar and 670 is fermi, having said that keplar(upcoming) should be more powerful than fermi (old)

 

You are comparing card vs card and not core vs core. Fermi cores are stronger than Kepler cores when compared 1 to 1 but that's not the only thing that determines the card's overall performance.

As far as performance goes, 660m<670m<680m. The 660m and 680m are indeed using Kepler cores, which are weaker than the Fermi cores of the 670m, but like I said, there are many other things that determine overall performance.

Looking at the 660m vs 670m specs, there are 384 shader cores (Kepler) vs 336 shader cores (Fermi) for the 670m. The 680m is rumored to have 768 shaders.

 

The 660M is only a 128bit card while the 670M is a 192bit card...this makes a big difference.

As misterhobbs says, you can just compare Cuda cores to determine which is stronger. He also stated the performance progression of the cards correctly.

 

I am little confused on the Model B. Is there a slot 2 for a msata or that only applies to model C from the manual.

 

All three models have the msata slot.

The p170em has 2 2.5" hard drive slots in addition to the msata slot and the p150/151em has 1 2.5" slot.

 

oh.. that clears up my confusion. thanks.

 

Saying that Kepler cores are weaker than Fermi is wrong.
The Kepler architecture has changed the way of the cores are placed/used/needed for performance.
Basically if you take Fermi cores with a value of 1, you need a Kepler core value of 2 to match the same performance.
384 fermi = 768 Kepler.
That's because nvidia dropped the 1 dimensional shader architecture that we add until Kepler shown up, in favor of a different method.
Hope this helps.

 

I really hope we can run the GTX 770m or 8970m from next year on the P150EM if we get a hacked vBIOS or whatever.

If not then what is the point in buying Clevo over MSI or Asus or... Alienware :'(

 

Asus doesn't allow the MXM cards to swap on their later G series like G74 and G54 I don't know about the new G75 and 55. looks like if Clevo doesn't shape up we'll have to go MSI barebones

 

If you are referring to upgradeability of the GPU, Clevo is no different than any other laptop manufacturer. You should never count on being able to upgrade your GPU in any laptop. While it is sometimes possible, it is rare that the thermal solution, vBIOS, power supply and even the motherboard will support next generation GPU's.

 

The point, for me, is to have a nice gaming laptop. When I'm ready for a new GPU, I'm typically ready for a new CPU as well. Heck, I'm typically just ready for a new computer in general. I'm buying the P170EM because I'm ready for a fresh system after having my W860CU for 2.5 years. I'm anxious to have the nice new screen, the faster GPU and CPU, the USB3.0 ports, the Sata III hard drive speeds, and a host of other things. I wouldn't put a 7970m in my W860CU even if I could.

 

Looks like the 680M is slated for an August release.. Perhaps along side the P370EM..? Resellers are saying ~10% and $200 over the 7970M.

Should we expand this thread title to include P370EM speculation..?

 

That would be quite odd as the P150EM, P151EM and P170EM already are available.. there's no speculation regarding them, only the P370EM.

 

I would like to know what resellers are claiming it will be more powerful than the 7970M.

Granted that everything currently posted for the 680M is SPECULATION but a quick google search is showing it will be about the same performance as the 7970M.

Just one of a few primitive and highly speculative examples of what you can find with a quick search.

Well according to this dude
http://forum.notebookreview.com/gam...185-amd-7970m-vs-gtx-680m-34.html#post8566786

 

Exactly. I think this thread helped deter a lot of random threads from popping up about the 1x0EM models. Since the 370 is another EM model, why not leave this thread for the speculation for it..? Sure, it'll branch off once more is known, but there's already plenty of repetitive posts, why not extend this one a bit to keep a few of the coming ones away?

It was a different European reseller, though that's an interesting post you pointed out. Similar, but more info than what I was provided. Again, as pointed out, no one's gonna have solid numbers at this point, just speculation.

Edit: given this info this morning.. Can't really do my homework on the scores at the moment. Anyone able to verify that the ones we know are legitimate?

Vantage

GTX680M 25236
HD7970M 22177
GTX675M 17260
GTX670M 13874
GTX660M 12675

 

That score for the GTX 680M looks like the 3DMark Vantage score for the GTX 680 desktop GPU.

I have yet to see any benchmark that indicates that the GTX 680m will actually perform better in games than the 7970m. Though, since its not released yet, I suppose anything is possible.

 

+1

The only leaked benchmark I've seen so far for the 680m showed a 3dmark '11 score of just under 4700 to the 7970m's ~5800. As you said anything can happen though. The leaked one I'm mentioning is from early April.

 

I want my 7970m P150EM so freaking bad -_-.
