AMD Athlon 64 X2 65nm Brisbane-Core
       
    
Now that we've got a good picture of how the "Brisbane" and "Windsor" cores compare with regards to power consumption and thermal performance, we'll shift our focus to performance.

       In our first round of tests, we focused on CPU performance, doing an apples-to-apples comparison between the "Brisbane" and "Windsor" based Athlon 64 X2 5000+ processors.  The first test run was SANDRA's Arithmetic Test followed by the Multi-Media test component.
        
    
When we do a side-by-side comparison of the Arithmetic test results, we see the "Brisbane" core held a small edge over the "Windsor" by 23 MIPS while Whetstone results swung the other way, with the "Windsor" core leading by 49 MFLOPS. With the Multi-Media test, we saw the 65m "Brisbane" top the "Windsor" in both Integer and Floating-Point calculations, with the Floating-Point calculations showing the widest margins at 94 it/s vs the integer test which recorded a 21 it/s difference.
