AMD unveiled its smarter Athlon II processors


AMD unveiled a faster set of seven new Athlon II processors that provide minor speed increases to many of its budget and mainstream offerings while leaving steady their prices and power consumption.

At the top of the line is the X4 640, a 3.0GHz, 95-watt quad-core CPU, which is expected to sell for around $122.The 45-nm X4 640 contains 64K of L1 instruction cache per core and another 64K for data. L2 cache is 512K per core, 2MB total. It's equipped with a 128-bit memory controller that can handle DDR2 and DDR3 memory at frequencies up to 2.0 GHz. AMD's HyperTransport 3.0 spec is on board, jockeying inter-processor communications at 4.0 GHz (2.0 GHz in each direction) via one 16x16-bit link.

Next is the quad-core X4 610e, a 45-watt version of the 640 that runs at 2.4 GHz and is priced at $143

The two tri-core parts: the 95-watt 3.1 GHz X3 445 at $87 and its 45-watt cousin, the 2.5 GHz X3 415e at $102.

Also new are a pair of dual core parts, the 3.2 GHz X2 260 and 2.9 GHz X2 245e, which are priced at around $77.

The 415e (formerly the 405e) has received the most significant speed boost, 200 MHz, while all the others have received an additional 100 MHz.

All these models worked with the recently released 800-series chipsets, and have been tested by AMD and the CRN Test Center on the AsusTek Crosshair IV Formula motherboard. Other compatible motherboard includes the Asus M4A89GTD-Pro, Gigabyte 890GPA-UD3H and MSI's 890FXA-GD70 and 890GX-GD65 models.

AMD said the new parts also work with its 785GX chipset, which is found on the Asus M4A785TD-M EVO, Gigabyte GA-MA785PGMT-UD2H and MSI 785GM-E65 motherboards. All the new processors are compatible with the AM3 and AM2+ 938-pin socket.
