Some naughty monkey has broken their NDA by sharing AMD's slides with everyone. If you know anything about making charts and graphs, then some of these slides are pretty damn hilarious. Check out the graph that begins at .8 and then increases in .1 increments up to 1.7. If you only look at the bars you may think that the performance of the HD 6850 is way more than twice as good as the GTX 460 because the red bars are more than twice as tall. However, when you factor in the scale you will see that the tallest red bar is just over 1.6 times faster than the GTX 460.
