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

Performance:
550M < GT555M=GT635M < GT650M

So GT650M is not a rebadged GT550M.

Lets hope so! I still dont think its a 28nm part.. If nvidia really rebrands the 570m and 580m

The naming isnt a good indication though, especially with nvidia, there are often times cards with higher numbers which have slower perfomance, their naming is messed up

nVidia has a very long, proud, tradition of screwing the pooch on product names. I mean.. Surely an 8800-GTX is Faster than a GTX-280? Right? oh.. Wait.. How about a GeForce 405, has to be a LOT faster than a GeForce 295.. I mean.. its a whopping 110 more!!

GT650M

Spoiler :

GF108(GT425M/GT435M/GT525M/GT540M/GT550M)

Spoiler :

You may check their difference.

what does that proof? as I said there are many revisions of the 555m for example and many variations..

especially moving from the gf106 to gf116 the 555m chip had some changes... So the 650m chip will probably also look different than the 550m
Im not saying the 650m is completely the same chip, but It will probably not be significantly more powerful than the 550m if the 670m is only about 5 - 10 Percent faster than the 570m

And as you see in the pictures the die size looks nearly the same

Yep nearly, but they aren't laid up next to each other so it's hard to tell by eye

Here is a picture of the 540m chip (which the 550m is based on) which looks like a similiar size to the 650m

Spoiler :

It is not a 540m chip but MCP79MXT-B2 with GeForce 9400M integrated.

[gamba66]

yes but the other chip is from the y570 mainboard and from your picture too

so whats your point? the die size from the 650m to the 550m isnt different as you originally claimed as you can see in these pictures

Here is even a picture of the 550m from the y570 mainboard (the chip on the top of the picture)

Spoiler :

And here the clevo 11.6 inch with 650m from your picture

What I claimed is 650m and 555m have different die sizes while GT650M has higher performance than GT555m and of coz GT550M.

Many chips have similar die size as GF108(e.g. G96B). Does it mean GF108 a rebadge of G96B?

you were the one that mentioned different die sizes as an explanation for the 650m being kepler, remember?

Its kind of obvious the 650m and 555m have different die sizes, since the 650m is the followup of the 550m and belongs to another perfomance class then the 555m which belongs to the enthusiast class.. So why do you compare two chips which are different in the first place ^^

So if you compare the 650m, then compare it to its predecessor the 550m (which look about the same size)^^

Then how can you prove 650M a rebadged 550m?
How can you explain an over-class performance increase?

[gamba66]

Ask nvidia how they come up with such crappy naming schemes haha

Lets just wait and see, if were lucky we will get some definite answers when the Cebit in Germany starts (Maybe im going there since I live in Germany) on the 6th of March.. Its rumoured that all the notebookvendors display their new IVB products there

I thought about taking my USB Stick with me, with some benchmark programms and hwinfo apps like gpu-z and so on and just get some real numbers from the notebooks shown there (IF they are shown there)
