AMD Athlon II X4 640 Processor Review

Price: $122.00


Between the top CPU manufacturers, AMD has been producing a lot of chips over the past year or so. This allows the consumer to choose exactly what is right for them, based the processor's speed and their budget. The Athlon II and Phenom II series have been causing quite a stir in the market due to their low prices, which make them a great bang for the buck. Less than a month ago, we saw AMD drop a six core processor for just under $300, making it quite attractive when compared to the price tag of Intel's six core i7 980X, which retails for around a grand. With a bit of tweaking on the same silicon as the X4 635, AMD has been able to squeeze a bit more performance the Athlon II X4 640, which has a 100MHz higher clock than the 635. This increase in speed will give a bit more performance to those wanting to get the bang for their buck. At launch, the AMD Athlon X4 640 will retail for around $122, making it an inexpensive quad core for gamers and HTPC builders alike.


Closer Look:

There is no physical change to the AMD Athlon II X4 640 as far as the looks go, the difference is under the hood. Here, AMD took their Athlon II Quad Core silicon and found some more speed by bumping up the multiplier up by a half, giving the CPU a 100MHz increase to take its place as the top Athlon II X4 processor. This increase also has allowed AMD to drop the price of the older Athlon II X4 635 to sub $100 prices. This makes the Athlon II X4 series quite tasty for those wanting a high performance, low cost chip. The Athlon II X4 640 uses an increased multiplier of 15x, with the base clock of 200MHz . This is where the 640 gets its 3.0GHz rated speed. All of the other specifications remain the same, this includes: HyperTransport 3.0 support, 45nm manufacturing process, and AM3 desig. The Athlon II X4 640 still has the same L1 cache of 64KB on each core for data and instructions and a L2 cache of 512KB per core, for a total L2 cache size of 2MB. Other features still include AMD Cool 'n' Quiet 3.0, AMD Balanced Smart Cache, and Direct Connect Architecture.










Now that we have seen the physical aspects of the AMD Athlon II X4 640, we can dive into its performance.
