HIS Excalibur ATI Radeon X850XT PE IceQ II Dual DVI VIVO 256MB PCIe Review

Introduction

Is it ay wonder that as processor manufacturer increase the speeds of their chips that video card makers aren't going to be far behind them. When ATI introduced the the X850 a number of people questioned whether it was worth the silicon since they claim the difference between it and the X800 is not all that different. That is something we will be examining it in our review as well since we just came off of reviewing a X800 a week or so ago and we will be able to compare it with the exact same system against the HIS X850 XT IceQ Turbo VIVO.

To give you an idea of where the X850XT comes from and where it stacks up among the many other X series cards that ATI is currently offering we have included this chart so you may better understand it. If you do a side-by-side comparison with the X800XT video card the X850XT you can see that the X800XT is actually a better card since in theory its clocks faster with a default memory speed of 560Mhz to 540MHz.
