After Nvidia's launch of its GTX 200 series a couple of days back, AMD has an answer in the form of the new Radeon 4850 high end graphics card. If all goes well, AMD should be launching it on June 25th.
The RV770 processor that lies in the heart of this new soon-to-be flagship model for AMD, runs at 625MHz and uses GDDR3 RAM clocked in excess of 2000MHz. The earlier RV670 core had 320 stream processors while this one has 480. Apart from support for Shader Model 4.0, OpenGL 2.0 and DirectX 10.1; this core also newly includes 'Game Physics Processing'.
Meanwhile, Nvidia's new top of the line GPU, the 9800 GTX+ has been announced without much fanfare, which will take the battle against AMD. These launches bring good news even for those who cannot afford them -- prices of existing mid-range models are almost sure to fall, giving users more value for money. As these two big players fight it out to produce faster graphics cards and compete with pricing, irrespective of who wins, buyers stand to benefit the most.
