timing 11 CL Latency 13
The first 11 is the CAS timing. The second 11 or 12 is the version of Serial Presence Detect (SPD) used for communication between the RAM module and the computer. The B3 or B4 is the reference design file used for this design and Revision number of the reference design used.

The CAS timing is what matters. The lower the number the fewer clock cycles it takes so in effect its faster. In this case, they would perform identically, although the B4 is technically a newer version.
