Considerations for cainiao becoming masters

lines, therefore, we come to the conclusion that increasing the number of road lines or the width of the road can increase the traffic. So: 250 MHz x 8 = 2G, or: 100 MHz x 20 = 2GBut: Obviously, the width of the road is better than that of more lines. The same is true in PCs. Generally, the latter formula is not used. Reducing FSB will greatly affect the performance. However, FSB is inaccurate on some AMD CPUs, but the theory is the same. It should be noted that most CPU frequencies are locked
