In addition to socket FM1 Athlon II X4 631 and 651 CPUs, AMD has silently rolled out two more models, the Athlon II X4 638 and 641. Spotted by CPU-World, the Athlon II X4 641 already seen before has been joined by a totaly new part, the Athlon II X4 638.
In case you are wondering, the Llano Athlon II X4 CPUs are simply Llano dies with a disabled GPU part. The fastest Athlon II X4 641 is a quad-core that works at 2.8GHz, has 4MB of L2 cache and features SSE3, AMD64, Enahnced Virus protection and Virtualization. As noted, the Athlon II X4 641 fits into FM1 socket, has a 100W TDP and has been seen before retailing at around US $95.
The Athlon II X4 638 is also a quad-core FM1 socket CPU that ticks at 2.7GHz, making it the fastest AMD 65W TDP CPU, at least for now. It also packs 4MB of L2 cache and has pretty much the same features and specs as the Athlon II X4 641. Although it is still not available in retail/e-tail, the offical price of the Athlon II X4 638 is set at US $81.
