AMD Phenom II X2 560 dual core processor
Based upon the Callisto core, the AMD Phenom II X2 560 dual core processor is expected to be released in third quarter of 2010. The Callisto core is essentially based upon quad Deneb core with two of its cores disabled. The yield issue in the production results in non functioning cores. After the production when the quad core Deneb processors are found faulty in one or two of the 4 cores, two of the cores are disabled, giving the dual core Phenom II Castillo core.
The Phenom II X2 560 has a core frequency of 3.3 GHz and will have a total of 1 MB L2 cache ( 2 each of 512 KB in the two cores). It has a total of 6 MB of the L3 Cache. With 7MB of the total Cache memory, this dual core is looking to give a tough fight to the Intel processors – especially when it is expected to ship for a price under $100 ( some more information on the pricing in awaited).
The Front Side bus is 2 GHz HyperTransport that will make the communication with the chipset superfast. The processor will work of AM3 socket, which will mean that many of the existing motherboards with be able to support the Phenom II X2 560 dual core processor.
The TDP rating of the Phenom II X2 560 will stay at 80 Watts. The fastest callisto processor available to date is the Phenom II X2 555 that has a core frequency of 3.2 GHz
The benchmark results for the AMD Phenom II X2 560 are not yet available. Since the core frequency of Phenom II 560 is 3% over the Phenom II 555, it is expected that the CPU intensive benchmarking results to be 2 to 3 percent better than that of the Phenom II 555 benchmarks.
