Both the AMD Athlon X2 5050e and the Athlon X2 7750 processors serve a place in today’s market, but the roles for the two processors are clear as night and day. The AMD Athlon X2 5050e is perfect for those wanting to build a system that uses low power and has a quiet cooling solution. The thermal properties on the Athlon X2 5050e were amazing and the fact that the processor runs at just 41C on the factory heat sink was most impressive. With an aftermarket cooler and a case with good airflow the Athlon 5050e could easily be air cooled, which is amazing for a processor running 2.6GHz. The AMD Athlon X2 5050e felt fast on the desktop and you wouldn’t know it was energy efficient if someone didn’t tell you.
The AMD Athlon X2 7750 breaths much needed new life into AMD’s dual-core processor series that hasn’t seen any significant changed since the Brisbane cores came out back in back in December 2006. The new Kuma core brings many significant features to the table, but the most obvious are the larger cache sizes and the faster HyperTransport 3.0 bus. The performance results speak for themselves and the AMD Athlon X2 7750 is a very fast dual-core part that was able to keep up with the Intel Core 2 dual-core processors we tested it against. If only AMD could have come out with these Kuma (K10) cores a year ago they would have given many of the Intel dual-core processors a run, but obviously that did not happen.
When it comes to pricing, the AMD Athlon X2 7750 is just $79 and that is a good thing for in this economy the lower the price, the better the chances of selling it. The AMD Athlon X2 5050e on the other hand is even less expensive at just $61 with today’s price drops. That makes its cost ~30% less than the AMD Athlon X2 7750 and the easy choice for those going green or looking to built a silent system.
Legit Bottom Line: AMD’s Brisbane based dual-core processors have been around for two years and have finally been replaced by the newer Kuma core that is derived from the Phenom series of processors.
