Does AMD have a webpage similar to ark.Intel.com?
Whats wrong with this:
http://products.amd.com/en-us/search
I don't see much marketing there, its similar to the 'ark' @ intel. Just gives you AMD CPU specs
If you're wanting to see actual benchmarks of these AMD processors VS the Intel processors then you can check out AnandTech.
