AMD let loose no less than six new processor models in its value-mainstream Athlon II series. Spread across its dual-core (X2), triple-core (X3), and quad-core (X4) lines, the new models seek to displace existing ones from their price-points and hold key value market positions. Leading the pack is the Athlon II X4 640. Based on the 45 nm Propus die, the X4 640 has a clock speed of 3.00 GHz (15 x 200 MHz), with 512 KB of L2 cache per core, and 4 GT/s HyperTransport 3.0 interface. Built on the AM3 package, the X4 640 supports DDR3 and DDR2 memory standards. It has a TDP of 95W. This chip is priced at $122. The second quad-core model is the energy-efficient Athlon II X4 610e. With a clock speed of 2.40 GHz (12 x 200 MHz), the X4 610e comes with half the TDP of standard models, just 45W. Energy efficiency comes at a small premium, with the X4 610e going for $145 a piece.
The triple-core Athlon II X3 series also gets two additions, with the X3 445 and X3 415e. The X3 445 is based on the Rana die (Propus with one core disabled), and has L2 cache of 512 KB per core. It is clocked at 3.10 GHz (15.5 x 200 MHz), and has a TDP of 95W. It is priced at $87. The energy-efficient X3 415e is clocked at 2.50 GHz (12.5 x 200 MHz), has 45W TDP, and is priced at $102. Dual-core Athlon II X2 chips get the same treatment, with a new fast and energy-efficient model, each. Based on the 45 nm Regor die, the Athlon II X2 has two physical cores with 1 MB of L2 cache per core. The Athlon II X2 260 introduced now, has a clock speed of 3.20 GHz (16 x 200 MHz), 65W TDP, and is priced at $76. The energy-efficient X2 245e is clocked at 2.90 GHz (14.5 x 200 MHz), and has a TDP of 45W. This one goes for $77. All prices are per unit in 1000-unit tray quantities.
