Second, over the years, Intel has actually upgraded CPU performance in situ. The performance gap between each generation is very low, so the old CPU has a good market. Secondly, due to the frequent changes in the specifications of Intel's motherboard CPU interface, the CPU interface is basically' upgraded' once every two generations. If you don't want to change the motherboard and just want to upgrade the CPU, you can only go to the second hand, so Intel's CPU is relatively preserved and even appreciated (for example, I3865438+ some time ago)
As for the packaging of two clocks, the early Intel CPU (such as Pentium 4 or Pentium D) was also pin-like, just like AMD. Later, the pins were moved to the motherboard. AMD didn't move because Intel registered related patents, so AMD can't use this package. But the number of disassembly and assembly of CPU should not be very frequent. Just pay attention when installing. This is just the difference in packaging method, which does not affect the performance.
