You remember Calisto core, which is actually a Deneb quad core with two cores disabled. Since AMD didn’t really have many different cores it had to improvise and with 7MB of total cache Calisto definitely looked like a good dual core CPU.

The currently fastest Calisto based dual core is Phenom II X2 555 running at 3.2GHz with 80W TDP and Q3 2010 should see the arrival of the new Calisto clocked 100MHz faster at 3.3GHz. The name is also quite predictable, AMD will brand this new CPU Phenom II X2 560 and it will retain the 80W TDP.

The CPU has 1MB of L2 cache, 2x512KB per each core and a total of 6MB L3, the same amount as Deneb quad core. Calisto is quite fast and it should ship under €100 when available.
