|  | | Sapphire Radeon HD 3870 Review @ TPU |
Sapphire's new HD 3870 card is based on AMD's RV670 GPU which is made in a 55 nm process with 666 million transitors and support for DirectX 10.1 and PCI-Express 2.0. This card that is sold for around $249 is intended to be AMD's new offering for an upper midrange card - but can it beat the GeForce 8800 GT?

another thing ... there are 2 bridge ports on each card, they need to be both connected between eachother ?!? | | | | Another quick search and it seems one of the things CrossFireX did is eliminate the need for both connectors according to the Inquirer ... info is pretty vague on the AMD / ATI site on it and maybe they should address that !!

Second, the connectors, as you can see, need only one to go between cards, unlike what they have now where two are needed. This in effect gives them a lot more headroom, allowing even more-way CrossFire if need, or more likely if there is ever a board that has the PCIe2 lanes. That is nit-picky though. Third, the notes on the slides shown to the Inq say that only Dual is supported at launch with Triple and Quad in Q1, January is strongly suggested.
| More on CrossFireX emerges - The INQUIRER | | | | guess that 3 and 4 way crossfire need one connector because all pcie lanes are 16x
but I have one 16x and the other is 4x so ... I guess using them both compensates for the reduced bandwidth on the second pcie
we shall see when the card arrives and I can begin testing | | | | Another useless piece of GetForced-competing quickly-made useless hardware. | | | | Quote:
