ATI is scheduled to release their new top model - the X1950XTX - in late August. The new chip, codenamed R580+, is no different to the R580 in terms of design, production process, and clock speed, but features GDDR4 support. It keeps 16 Pixel Shader pinelines, 48 Pixel Shader processors, and a 256Bit memory controller. It is manufactured by TSMC using a 90nm process and clocked at 650MHz. Utilizing GDDR4 memory, the X1950XTX is the first card that steps into the era of 2GHz DDR. The price is set at $399.

A picture of the reference card:The RV570 will be known as the X1950 Pro, a successor to the X1900GT. The RV570 has 12 Pixel Shader pinelines, 36 Pixel Shader processors, and a 256Bit memory controller. Manufactured by TSMC using a 80nm process, it's clocked at 600MHz with 1.4GHz GDDR3 memory. The heat sink occupies a single slot. The Radeon X1950 Pro is the first GPU with a built-in Compositing CrossFire Engine, eliminating the need for a master/slave card.The X1950XTX is to be priced around $400, the X1950 Pro's prices will range from $200 - $250.
