| AMD's AM2 Platform DDR2 ... Moving On | |
|
(Review by MS May 23, 2006) |
Hardware Virtualization
Regardless of the Level2 cache size (full cache or half cache), the AM2 processors are all using the "Windsor" code name. New AM2 platform-compatible model numbers are:
Besides the new memory controller for DDR2, the other novel feature is Hardware Virtualization managed by a hardware Hypervizor as opposed to software virtualization. On a side note, the single core Athlon64 and Sempron core uses the code name "Orleans" and weighs in at 81.1 million transistors and a die size of 103 mm2.

Test Configurations
To put things into perspective, we are using dual and single core configurations for comparison along with a dual processor Opteron system. The point is not to say that one is better than the other, rather it is to give some idea where a given system would currently be, and whether there is really any need for upgrading or not. Every processor and every system has its own strengths and weaknesses and depending on one's preferences, some of the issues will be irrelevant whereas others may influence a purchasing decision -- or not.
