It should be noted that both new AMD processors were tested using DDR3 memory because there aren’t currently any available BIOS updates to use these processors on the AM2 platform. This should obviously take place some time after release but until then our numbers should remain valid as there is no real difference between DDR3-1333 and DDR2-1066 in terms of performance.
First up we tested the processors using WinRAR in both single thread and multi-thread modes. The Phenom II X2 550 and Athlon II X2 250 are the highest clocked processors of the pack and it showed in the single thread test. The Phenom II X2 550 produced the best result with a throughput of 862KB/s followed by the Athlon II X2 250 with 780KB/s. When testing with multiple cores the quad-core Phenom X4 9950 and Phenom II X4 910 processors had a natural advantage over the dual-core competition. Still, despite of being two cores lighter the Phenom II X2 550 was not a great deal slower than the Phenom X4 9950 making it the fastest tested dual-core processor by quite a margin.
