Radeon HD 4870, 4850 pixellated for the first time
Worth noting are that two 6 pin power connectors are needed for the power hungry 4870. One can only guess how many the X2 will need…
The first two 4000 series cards will be powered by the RV770 chip which is built using the 55nm process and offers 480 Stream Processors. both cards will feature a 256-bit memory interface PCI-Express 2.0 support, CrossFireX, Unified Video Decoder (UVD) 2 and DirectX 10.1.
The Radeon HD 4850 will be equipped with 512MB of GDDR3 memory and is said to cost in the realm of $229 to $249.
The Radeon HD 4870 will signal the ‘proper’ return of AMD/ATI to the high-end segment as this card will utilize one RV770 chip paired up with 1024 MB of GDDR5 memory. The HD 4870’s price tag will hover around the $329 to $349 zone. Both Radeon HD 4800 cards are said to be ready for a mid-June release but the Radeon HD 4870 will apparently become available in July.
