I have been knowing that AMD Sempron is 32-bit processor. But on Canada Computers website (http://www.canadacomputers.com) I was a bit surprised at the labeling in CPU list, indicating like Sempron is 64-bit. It was labeled such that "AMD Sempron 2500+ 64Bit 1.4GHz Socket 754 256KB L2 Cache 1600MHz HT (Retail Box)" Is this their mistake? or My misconception?
