In Technology Bytes RV770 Meets GDDR4, PowerColor Radeon HD4850 PCS+ D4 Planned
In an exhibition of pure technological flexibility by AMD, the RV770 graphics processor is going to be used along with GDDR4 memory, in PowerColor's newest Radeon HD 4850 PCS+ GDDR4 graphics card. The inclusion of GDDR4 memory is to boost the memory clock speeds and to provide room for a little more memory overclocking.

The PCS+ GDDR4 features a GPU cooler designed by ZEROtherm, which is advertised to keep the GPU up to 10 °C cooler than what the reference cooler would. It features heatsinks for the memory and the VRM area. It features 512 MB of GDDR4 memory clocked at 2.20 GHz, with the core clocked at 675 MHz. The card supports CrossFireX, and sports dual-DVI connectors. There is no word on its availability pricing as of now.
