The TLB bug is as old as K6-III

Written by Fuad Abazovic

L3 cache is tough


We learned that the good old K6-III had a similar L3 cache errata to what we now know as the TLB bug, and the K10 simply inherited this almost a decade (nine years) old problem. After more than a year AMD finally found a solution for TLB and the new B3 CPUs will finally fix this raging issue.

The K6-III was the first CPU to have L3 cache from AMD and it had some similar issues. At that time AMD didn’t make a big deal out of it and it all went by quietly, but at that time AMD didn’t really have a strong server market presence, as TLB mostly affects servers, not desktops.

It is good to know that AMD solved this issue, but the issue itself ended up costing AMD billions. What can you do, sooner or later you have to slip.
