Supposedly, these run at 25 % less wattage than the standards and have a full 1M level 2 cache. This means that they are the same frequency at 3200+, but lower at 3000+ and 2800+ but with the bigger cache. We will see when they can actually be obtained. They are $15 more than the standard 64's, according to their OEM costs. Hopefully, we will see these soon.
