Pictures of a non-working sample of AMD’s upcoming RV670 graphics processor – a chip designed to bridge the massive gap between the high-end and mainstream cards in the ATI Radeon HD 2000 series – have shown up on a Taiwanese website.
The chip is rumoured to have been fabbed on TSMC’s 55nm process and will reportedly be clocked at 600MHz.
There will be the same 320 stream processors as there are in R600 (and are presumably arranged in the same way). However, RV670 is reported to only have a 256-bit memory interface – just half of what R600 has available.
This is connected to eight 32MB Hynix DDR3 DRAM chips, making a total of 256MB memory which is rated to 900MHz (1800MHz effective).
Additionally, the GPU will support CrossFire and the rumours suggest that RV670 will be Shader Model 4.1 compliant (DX10.1) along with also supporting PCI-Express 2.0. Our own sources have also confirmed that the GPU will integrate AMD’s Unified Video Decoder.
The card pictured has a single slot cooler and a single 6-pin PCI-Express power connector. These should be as a result of the benefits of moving to 55nm and also from PCI-Express 2.0’s increased power draw through the interconnect, which is up to 150W from 75W on older versions of the specification.
DailyTech also reports that the card is expected to appear in AMD’s lineup in Q1 2008 and at this time pricing hasn’t been finalised.
Obviously, the card isn’t going to be as fast as a Radeon HD 2900 XT, but won't be far off either – will this take the mid-range to where it should have been originally?
