Introduction

A few months ago ATI introduced their new Radeon X1950 Pro series of video cards. These cards are based on the new RV570 core which is made in a 80nm process. Usually all higher end cards are made to specifications of ATI and the boards partners have to sell that product, they are not allowed to make any changes to the PCB, clock speeds or memory configuration. Recently ATI has lifted that limitation from the X1950 Pro series, which is why we are seeing a number of different products from manufacturers.

GeCube has focused on cooling and overclocking with their FZ Cool Champion Edition. A small TEC (Thermo-Electric-Cooling) device reduces the GPU temperature more than it would be possible with a traditional cooling fan.

A TEC is basically at heat pump. Heat is moved from one side of the metal surface to the other side, it does not magically destroy heat. This whole process consumes power so the hot side is hotter than what was moved from the cold side.

The important numbers here are the shader count and the number of ROPs, which are both lower than on the high-end products.
