Not even close...Core 2 Duo by a mile.

Cache is a measure of the amount of a type of extremely high-speed RAM located on the CPU. Commonly used instructions are held in the cache so that they can be accessed very quickly by the CPU without having to get the information from the actual RAM (which involves sending a message to the RAM and then waiting for a message back).

FSB, or front-side bus, is the speed at which the RAM, CPU, and other components on the motherboard (such as PCIe/PCI bus and hard drive) are linked together. AMD uses a slightly newer system than the FSB known as hypertransport. It tends to be faster and dispenses with the northbridge chip used to control memory speeds. The northbridge in the case of Hypertransport is instead located directly on the CPU (aka the on-die memory controller).
