<p><span style="font-size: small">From a variety perspective, the Radeon HD 6800 series is certainly the most interesting Radeon *800 series launches in recent history. AMD typically launches with (and only with) reference cards, and then in time partner-customized cards show up as AMD approves the designs and partners have the time to do the engineering legwork to make custom cards. In the case of the 5800 series this was a particularly long period of time, as TSMC&rsquo;s production shortage meant that AMD was intentionally shipping out reference cards as fast as humanly possible; and as a result we didn&rsquo;t see our first custom 5800 series card until 6 months later in February of 2010. It was a much more controlled launch than normal for AMD.</span></p> <p><span style="font-size: small">The 6800 series on the other hand turns that on its head, giving us a much more liberal launch when it comes to card designs. While the 6870 series launched and is still all-reference, the 6850 is the opposite, having launched with a number of custom designs. In fact you won&rsquo;t find a reference 6850 in North America unless you&rsquo;re a hardware reviewer. With an all-custom launch the door is opened to a wide variety of cards with a wide variety of performance characteristics, so we have wasted no time in collecting a few cards to see what they&rsquo;re capable of &ndash; after all we&rsquo;ve seen what the non-existent reference card can do, but how about the cards you can actually buy? And how about overclocking, do the latest 6850 cards continue the tradition of the *850 being strong overclockers? Today we&rsquo;re going to answer all of that and more.</span></p> <p><span style="font-size: small"><a target="_blank" href="http://www.anandtech.com/show/4002/amd-radeon-hd-6850-overclocking-roundup-asus-xfx-msi">Read more...</a></span></p>
