CPU-Z

Here we can see the Athlon II X2 250 processor. Nicely ticking along at a steady 3 GHz. We've surely been waiting a long time for dual-core processors like these from AMD.
CPU-Z offers an easy and quick manner to verify all kinds of specifications. Here we can see that indeed this processor does not have any shared L3 cache, yet more L2 cache memory (1MB per core).
Next in line is of course the Phenom II X2 550 BE processor. If we were to x-ray the processor, you'd spot 4 cores as I'm 100% certain that this is the Deneb quad core based architecture with two cores disabled.
For the money this processor offers a truckload of performance thanks to its bigger cache. If you are interested, you can download CPU-Z here.
