when i tested my amddx4-100sv8b with speedtest yesterday(the whole pack just got running for a few weeks, and i had been running x5-133, so i havn't tested this before), it displayed a graph of 16kb l1 cache rather than 8kb. i took off the cooler and checked the printing, and found the model number on the cut corner to be 25544, which is that of the v16bgc ones, while normal sv8b models are expected to be 25398.
so, i guess this is a v16bgc product simply remarked as 8kb ones.

its just like this one: http://www.chipdb.org/img-amd-a80486dx4-100sv … graved-2373.htm
