AMD Athlon II X4 640 & X4 610e Review - PAGE 4

This program includes benchmarks for most hardware. The CPU arithmetic and multi-core efficiency benchmark will be run as well as memory bandwidth and latency.

The CPU arithmetic test showed that the Athlon IIX4 640 has significant gains over the X4 635. Right under these two is the Intel Core i5-661, followed by the overclocked-on-stock-voltages Athlon II X4 610e. The latter falls in between the Phenom II X4 910e and the Core i3-530 at stock. The memory bandwidth test put both Athlon IIs equal to the Core i5-661, although at an odd round 12GB/s. This phenomenon has been experienced many times in Neo's labs, including around the 13GB/s mark, and remains unexplained. It is like if Sandra was rounding up the results. Anyway, below them are the two other Intel processors. Above is the Athlon II X4 635 which did not get its result rounded off. At the top is the Phenom II and both overclocked Athlon IIs. The latency placed the contestants in almost the same order, except the Phenom II was above the stock Athlon IIs. For the multi-core bandwidth, the Intel processors remained untouched. The Athlon IIs were at the complete bottom.
