AMD is going all high-def with a new PC graphics card attached to the ATI brand. It is called the ATI All-In-Wonder HD and you’ll find the price of it set around $200.

The ATI All-In-Wonder HD combines Radeon graphics and Wonder HD tuner technology into one PCI Express 2.0 card. Key features of this new card include HDTV DVR functionality, unified video decoder technology and Windows Vista certification.

NVIDIA and AMD/ATI routinely fight it out in the video card market for dominance and the gamers dollar. Recently NVIDIA has been producing the better performing video cards, but AMD is back with a new family of GPUs selling at low prices that it hopes will grab some of NVIDIA’s market.

AMD announced officially today its Radeon HD 4800 series video cards with 800 processing cores. The HD 4850 carries a retail price of $199 and has a stock GPU speed of 625 MHz. Memory for the card is 512MB of GDDR3. AMD says that the GPU in the card can deliver a teraflop of computing power.

Windows computer users take for granted for the most part that you can upgrade your video card with ease. That is assuming you didn’t buy a factory built system that uses a small case or proprietary video card design. Mac users on the other hand are traditionally mostly limited to the video card that ships in their Mac system.

AMD announced a new ATI Radeon HD3870 video card that is optimized for use on the Mac, but retains its PC compatibility as well. The card is called the ATI Radeon HD 3870 for Mac & PC Edition. The card has a 256-bit memory interface and has 512MB of GDDR4 and 320 stream processors.
