AMD Delays Release of Quad-Core Athlon II, Preps Dual-Core Phenom II

From X-bit Labs: Advanced Micro Devices has decided to delay affordable quad-core and triple-core microprocessors made using 45nm process technology that it plans to sell under Athlon II brand and the chips will not be available before August-September. Still, the new breed of dual-core Athlon II X2 microprocessors is due in June timeframe during Computex trade-show.

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.

It is interesting to note that besides dual-core Regor processor, AMD will also release dual-core Callisto chip in June. Apparently, Callisto will be the long-awaited dual-core AMD Phenom II X2 chip with shared L3 cache and also made using 45nm process technology.
