AMD's 65nm Preview Part 2 - The Plot Thickens (Updated with Information from AMD)

3D Rendering Performance & Power Usage

3D rendering performance under 3dsmax 8 continues to be a strong suit of Intel's, but the E6600's advantage is narrowed dramatically by the lower clock speed and smaller cache size of the E6400.  Take price into account, and the E6400 is clearly the winner here.  Once again, there's no real performance difference between the 90nm and 65nm AMD cores here, which is quite impressive given the significantly higher L2 access penalty with Brisbane. 

Average power consumption under 3dsmax 8 is in line with what we've been seeing thus far, and taking both performance and power into account gives us similar results as well. 

Performance under Cinebench is closer between AMD and Intel, which also impacts the performance per watt results.  There's a slight performance difference between the Windsor (90nm) and Brisbane (65nm) cores, but nothing to write home about.
