Powercolour X1950Pro

1. Introduction

The RV570 is the first desktop GPU to be manufactured using the 80 nanometre process, and this core is designed specifically as a replacement for ATI's previous, R580 based, Radeon X1900 GT. It features eight vertex shaders and twelve pixel pipelines, each of which contains a single texturing unit and three pixel shader units, giving it a total of thirty-six. Alongside this, the core features twelve ROPs, and its Ultra Threaded Despatch Processor can handle 384 threads in flight at any one time, compared to 512 on high-end R580-based boards.

The X1950 Pro was released on 17th October 2006, with a MSRP of US$200 and is intended to replace the X1900GT in the competitive ~US$200 market segment. The X1950 Pro is the first ATI card that supports native Crossfire implementation by a pair of internal Crossfire connectors, which eliminates the need for external dongles as found in previous Crossfire systems. In terms of performance, the X1950 Pro trails slightly behind an X1900XT 256MB, due to a deficit of 4 texture units and 12 pixel shaders, as well as lesser GPU and memory clocks. The Radeon X1950 Series includes three versions with different core/memory clocks and pixel shader processors:

The fastest X1950 Radeon card is the X1950XTX. Its core speed is 650MHz, while the GDDR3 memory runs at 690MHz on a 256-bit memory bus.
