Functional RV670, RD790, Phenom X4 system demonstrated
The RV670 shown here did not come marked “RV670XT” or “RV670XTX”, just one of RV670 reference designs. The two boards worked in Crossfire, hidden in huge Thermaltake chassis. These boards had a dual-slot cooler, and power consumption is such that it can run just from the PCIe 2.0 slot alone. However, in order to keep the compatibility with PCIe 1.1 motherboards on the market, six-pin PEG connector was used… But to get back to the boards themselves, the design is something we would put between Radeon X1950 and 2600XT. 512MB of GDDR4 memory were used on the card, but the cards had no DisplayPort connectors. We had no means to measure the temperature, but you can keep the finger touching the back of the PCB in GPU area with no problem, even when 3D apps are running.
