Fujitsu-Siemens Amilo Sa 3650!

[Sneakers]

Anyone have any idea when we see a 4870 X2 or just a 4870 along side the sa 3650?

Well, if to think logically, there is no laptop with series 4xxx for now, if they came out, then and XGP will come out too with 4xxx series... it is my logically...

The question is: Will be there other manufactures that will bring new laptops with that connection port and when...?

[Sneakers]

Yes I surely hope so. But can anyone make it clear if the current PCI 2 8 bit connection on the sa 3650 is enough to handle the data amount from ex. a HD 4870? or this could be the bottle neck.

Well i think it can handle, cause AMD now is trying to make dual XGP, so with PCI 2 connection can handle and HD4xxx series... and don't forget, there is and 16 PCIe lanes cable too...

THere is a x16 cable, but you also have to have the x16 port on the laptop, and that part is a 52mm wide compared to 32mm, and there usually isnt room on a 13" for a long port.

PCIE2.0 x8 is the equivalent bandwidth of PCIE1.1 X16. Additionally the xfire between the GPUs would not travel across the x8, as in the XGP box there would be x16 between the GPUs, and then x8 to the laptop, so there should be enough bandwidth in x8 to handle a xfire setup when only possible to run at 1280x800. When using an external display it wouldnt travel back to the laptop anyway. So x8 should be enough to feed the GPU and transfer back the display data to 1280x800.

Now if you have a 17" 1920x1200 then youre going to need more bandwidth to the laptop and would necessitate the x16 port and cable.

Sounds good. but do anyone know if they are developing this? would be a shame if not, but AMD are off cause under some sort of pressure caused by their bad economy.

[TommyB0y]

I think AMD already developed it, but I'm not sure they will make a Graphics Booster themselves, need a manufacturer to pick it up, but with only one laptop so far, it might be a while unless Fujitsu sells a ton of them.

TI XGP is an external graphics card based on chip ATI M88 (Mobility Radeon HD 3870), connected to a laptop using a special connector is electrically compatible with the bus PCI Express 2.0 x8 or x16. The technology allows the use of two chips M88 to create the external CrossFire-system.

Just read AMD's own white paper on it where it shows the difference in the x8 and x16 connector. All that means is that the graphics booster will work on a x8 or a x16 laptop port if you have the right cable or adaptor. That doesnt mean all the laptop ports are capable of x16.

Hello
I' just have tested 3Dmark06 with the graphic booster in crossdisplay mode
The notebook is like at the origin. same OS , Same partition. Only a data restore was runing in the back but don't use lot of CPU. I've the ZM82 mobile turion and 4GO but Vista 32 .
