1, the main frequency, the main frequency is high, that is, the bus cycle is short, and the processing speed is fast. Everyone knows that. Just look at the price.
2, cache, is the cache, because the CPU speed is really fast, if it directly deals with the memory, there is bound to be a phenomenon of CPU waiting for the memory, resulting in a waste of resources, so the manufacturer made the cache to the memory in the future may use the instructions in advance to the cache, and the cache speed is much faster than the memory. It's about the same as a CPU. The CPU fetches instructions directly from the cache. The processing speed of the CPU really hasn't changed. But the entire computer system processes tasks much faster.
3, stability, mainly power consumption, whether it is CPU or memory... Are chips, to put it bluntly, are composed of transistors, field effect tubes, etc., these things have temperature drift. That is to say, after it works, it will generate heat, resulting in changes in parameters. Just like resistance in physics, temperature affects resistance. That is to say, the power consumption is large, the performance is unstable, and then there will be a series of problems that the user does not know. If you look at intel and AMD, the former is expensive, which is not only caused by the difference in the brand, the stability of the performance is a very important factor.
