PCIe Version 1.1 and PCIe Version 1 have the same throughput.
PCIe version 2 doubled the fequency of the PCIe bus, theoretically doubling the throughput, It also allows for up to 32 lanes on one slot
1.1 and 1 were the same allowing up to 16 lanes at 250 MB /sec per lane in each direction, Version 2 allowed up to 32 lanes on one slot and up to 500 MB/ sec per lane in each direction

PCIe version 2 operates at a frequency of 5 GT/s (gigatransfers per second) per lane. This translates to a raw data transfer rate of approximately 500 MB/s per lane, effectively doubling the bandwidth compared to PCIe version 1. Additionally, PCIe 2.0 supports multiple lanes, allowing for greater overall throughput depending on the configuration, such as x1, x4, x8, or x16.
Both versions of PCI-e have a bandwidth of 2.5 GT/s (giga transfers per second = 109/s). The version 1.1 revision addressed some underlying issues that may have affected performance, and also made device communication better (Allowed more POST information and GPU BIOS information to be inferred to the user) However, it didn't' change anything concerning transfer speed.

X1 means 1 lane, X16 means 16 lane, hence has 16 times bandwidth. Each lane is differential signal.
