Well even look the same, Phenom 9550 made used B3 stepping, (different architecture in production) which mean Phenom 9550 is TLB error free, wich mean more Performance for the CPU without loss of stabillity.
As AMD announced Phenom 9500,9600, may affected for TLB Error
TLB=Translation Lookaside Buffer is a memory buffer between cache memory and CPU, or CPU and main memory.
In few words: Every time you Run a program, a program load part on to RAM and part on virtual memory or so called swap file. TLB is just a table of contents wich Map a virtual memory address with a physical memory address. If this ewo values map, then the execute of the program can continue.
If these addresses can't find on TLB, then CPU had to ask details from page table, so call SWAP file, which is much slower to access.
If virtual and physical address don't map in there too, then the program generate an error (page exception fault) and has as a result a Blue Screen of Death (BSOD) if OS can't handle this error.
Even the TLB error was rare on 9500 AND 9600, AMD had to provide BIOS updates and hardwares updates to eliminate this problem, but that had a loss in performance up to 15%
Now the new Phenom 9550 even it looks idendical with 9500, comes without the TLB error and thus with 15% more power in theory.
Have a nice day.
