X-bit Labs reports AMD has decided to delay its triple-core (Rana) and quad-core (Propus) 45nm Athlon II processors to August or September. The dual-core Athlon II X2 processors are still slated for June, and in the same month we can also expect the dual-core Phenom II X2 (Callisto).
Earlier AMD planned to release its code-named Propus and Rana microprocessors in April, whereas the dual-core Regor was scheduled for June launch. However, the latest plans of Advanced Micro Devices seen by X-bit labs indicate that the world’s second largest maker of x86 microprocessors will only release Propus and Rana in August-September timeframe, more or less inline with the company’s new mainstream desktop platform code-named Pisces.
AMD Athlon II X4 600-series (Propus) is a quad-core processor with dual-channel DDR2/DDR3 memory controller (depending on platform) and 2MB L2 cache (512KB per core), Athlon II X3 400-series (Rana) is a triple-core central processing unit with DDR2/DDR3 memory controller (depending on platform) and with 1.5MB L2 cache, whereas AMD Athlon II X2 200-series (Regor) is a dual-core processor with 1MB L2 cache per core and DDR2/DDR3 support, depending on the platform.
