Lanes vs cores

[PCaddict9]

Do the number of cores in a CPU determine the number of lanes? Which cpu has the most lanes?

There is generally a correlation between cores and lanes. If you buy a 10 core CPU, it is highly likely to have more lanes than a 2 core. But this is determined by chipset/platform.

As a general rule, chipsets that begin with X have the most lanes.

No, doesn't really work that way.
There are many factors to determine just how many PCIe lanes can be supported, and things can get more complicated with PLX switch/bridge chips as well.
You can't even say more expensive CPUs offer more lanes, since you can get cheaper CPUs that have more native PCIe lanes than a far more expensive CPU.
