Room: Moderated Discussions
Just got a new article up, looking at the recent Bulldozer benchmark leaks. I go through all the reasons why the tests are inaccurate and will tend to under-estimate Bulldozer's performance. I also conduct my own analysis and discuss several conclusions about both Bulldozer and the uncertain nature of the tests.

Enjoy,
David
PS: I apologize for the terse explanation. Comcast just went out and I'm doing all the editing, etc. from my phone.
PPS: Phones are a crap replacement for PCs.
