CPU Information
ADA3800IAA5CU has the same basic features as ADA3800DAA5BV, but it requires new socket AM2. Socket AM2 is a socket with 940 pin-holes, and it's not compatible with socket 939 or older 940. Socket AM2 added support for DDR2 memory, which at this time (Nov 2006) may be as twice as fast as DDR1 memory used by socket 939 processors. Faster access to memory results in slightly faster CPU performance. On average, this socket AM2 3800+ is a few percent faster than socket 939 3800+, even though both processors have the same rating. For some memory-intensive applications the difference in speed may be as high as 15-20%.
