CES AMD today demo'd the version of its upcoming 'RV635' graphics chip and card combo that will incorporate a pair of DisplayPort connectors.

RV635 – expected to come to market as the ATI Radeon HD 3600 series – is scheduled for release later this month, AMD said in December 2007. It's a DirectX 10.1 part, it connects via PCI Express 2.0 bus and incorporates a second-generation UVD (Universal Video Decoder) core.

AMD's demo system featured two RV635's, one feeding a Dell 3008WFP DisplayPort-euipped monitor – launched this week - and a Sony Bravia TV via an active DisplayPort-HDMI adaptor. The other card fed a second Dell and a projector, again using an active adaptor.

There will be two 3600s, one clocked at 800MHz, the other at 600MHz. Both will connect to memory across a 128-bit bus, but while the slower chip will appear on cards containing at least 512MB of GDDR 2 memory, the faster ones will have 256MB of GDDR 3. As yet, memory clock speeds are not known.

Intel also demonstrated DisplayPort support, on a motherboard built around the 'Cantiga' chipset, it claimed. Cantiga's actually a mobile part that's due to ship with the next generation of Centrino, 'Montevina', in May.

However, the demo mobo was fitted into a desktop, and was driving two DisplayPort monitors – Dell ones again – via an add-in card with four DP connectors and the signalling chippery.
