what is the difference betwwen fsb & cache memory?

Answer 1

Cache memory has an even more dramatic effect on CPU performance. Cache memory is a small high-speed memory holding a copy of the pieces of main memory you used most recently. Note that there is an inverse relationship between speed and size -- partly that is due to economics, but if you had an infinite budget big memories would still be slower because of the longer signal travel times.

FSB front side bus is how fast the RAM and CPU run, the higher the FSB the more bandwith between the CPU and RAM. Some motherboards allow the CPU FSB and the RAM to run at different speeds, so you could have your CPU's FSB at 100MHZ and your RAM could run at 133MHZ so the information, once in your RAM would be processed faster.

Answer 2

in plain english, FSB (Front Side Bus) is like a road. The bigger the road, the more data can travel at any given time. Imagine a freeway with 4 lanes as oppose to a freeway with only 2 lanes.

Cache Memory is like a human's short term memory. Like when you go take an exam, you might memorize a lot of answers so that when you are taking the exam, you can quickly remember the answers. However, in the long run, you might forget about it.

But that may not always be true. Sometimes, you need Cache Memory for quick retrival. Say, for example, you love to cook a certain dish. It would be much faster if you memorized the recipie as opposed to reading the recipie every time. Think of memorizing the recipie as Cache Memory (Quick Retrival). The written recipie could be like virtual memory.

Answer 3

FSB is the speed of how fast the processor comunicates with the RAM. the cache is internal memory within the processor where it saves the last commands it has received and other temporary data in use.

Answer 4

FSB is the front side bus and used to indicate the speed of the bus...Cache memory is a fast-buffer memory that reside on CPU to streamline and speed up operation.

Answer 5

Cache memory resides inside the same chip of the CPU. It is the closest memory to the CPU core. It execute code fastest when the code is inside the cache memory. The size of the cache memory limited by the size of the CPU and packages. It is much more expensive to make cache memory than the outside DRAM memory.

FSB is the bus for the CPU connecting to the outside memory DDR or DDR 2 or SDRAM modules. If you run SW resides on the outside memory, it is much slower compare to run off the cache memory.
