Studio 1555 40nm GPU

Does anyone know if Dell usually upgrades their notebook graphic cards in-between platform changes? Isn't that what they have done with the 1555 seen as how the original was also based on Montevina (or was it Santa Rosa based? 0_o nvm [sic]).
If so, is it likely they'll add this as an upgrade if they don't decide to update the Studio line with Calpella & Quad core CPUs but rather wait till Q1 2010 for Arrandale. I'm confused.
I was hoping for a 128-bit gpu for the 1555, maybe the 40nm shrink can bring this to the Studio.

This is all I could find out:

Studio 15 - 15.4" / 15.6" Widescreen Laptop

* Dell Studio 1535 (Intel Santa Rosa Platform)
* Dell Studio 1536 (AMD Turion 64 Processor)
* Dell Studio 1537 (Intel Montevina Platform)
* Dell Studio 1555 (Intel Montevina Platform) (15.6" 1366 x 768 Widescreen)

Doesn't seem likely on the same platform. Which brings up another question, has the design radically changed since it's original conception? Because I wouldn't mind if Calpella kept the current design.

EDIT: So i'm considering buying the 1555, but it doesn't say anywhere on the product page whether the 4570 256MB uses GDDR2/3. Anyone know? Thanks in advance.

 

The problem is that most Dell notebooks have a soldered in GPU. It is therefore easier for Dell to design a brand new model around a new card.

 

Chances are that Dell isn't going to upgrade the specifications of the Studio 15 until they release the successor to the 1555. The design of the Studio 15 hasn't really changed too much since the 1535, so chances are that a 1565 (or whatever it may be) will have a similar design.

As for the video memory, I found just one blurb after a couple minutes of Google that suggested GDDR3, but don't quote me on that one.

 

Okay. I guess i'll go with the 1555 and get the successor (calpella & clarksfield/arrandale) upon release. Thanks for the replies guys.

 

So far there hasn't been any hint of a successor to the 1555.

The design has not really changed much since the original 1535, which I have. The 1535, 1536, and 1537 are all physically identical from the outside. The only differences are the chipsets. The 1555 is a slightly altered design; it's been stretched to 15.6" to accomodate a 16:9 aspect ratio, the media buttons have been completely removed and reassigned to keyboard shortcuts, and many of the ports on the left and right sides have been moved around.

I wouldn't count on a Calpella-based Studio 15, at least not any time soon. And if they do release one, it will probably have the exact same GPU, the ATi Mobility Radeon 4570. That's what happened when the Santa Rosa-based Studio 1535 was upgraded to the Montevina-based 1537; they still have the exact same GPU, the 3450.
