AMD Phenom II X2 550 Black Edition 3.1 GHz Socket AM3 Processor Review

AMD Phenom II X2 550 Black Edition 3.1 GHz Socket AM3 Processor Review - PCSTATS
Abstract: AMD's suggested retail price for the Phenom II X2 550 processor is a mere $103 USD ($110 CDN, £62 GBP), which positions it right between Intel's 2.6GHz E5300 processor and the Core 2 Duo 2.8GHz E7400 processor. This makes it both an inexpensive, easy upgrade for those looking to drop it into an existing socket AM2+ motherboard. The 3.1GHz clockspeed and potential overclocking headroom....

CPU Synthetic Benchmarks: SiSoft Sandra Processor/Memory

SiSoft Sandra 2009 - Processor Source: Sandra

Sandra is designed to test the theoretical power of a complete system and individual components. The numbers taken though are again, purely theoretical and may not represent real world performance. Higher results are best.

At its stock clockspeeds, the Phenom II X2 550 Black Edition just can't keep up with the Core 2 Duo processors, coming in last in every SiSoft Sandra test except for the SSE3 integer benchmark.

The Phenom II X2 550 Black Edition's overly-large L3 cache really puts the hurt on it in this test. Memory bandwidth is low, memory latency is slow. While the iSSE2 tests are a win for the Phenom II X2 550 Black Edition, these fringe cases won't mean much for overall system performance. Keep in mind though, these results are still pretty good given the price of this processor.
