He's my source, but He really shocked me with this.
Leaked K8L info.
This is unofficial, so take it with a grain of salt.
I had to load the file which was e-mailed to me into ms paint, so I can cover up the name & number as per my souces instructions. Now, looking at this, I thought the L1 cache was 32 kb for a total of 64 per core.
I do find it funny, because AMD already said that there is no such thing as the K8L. I did read somewhere that they would like people to not use the name K8L, but instead to use Barcelona, AMDs next quad-core Opteron chips.
