The AMD Phenom II 910e is a Quad-core processor that features the Deneb core. The predecessor to the Phenom II 910e was the 905e. The Phenom II 905e has the same bus speed as the Phenom II 910e, but the multiplier was x12.5 while the Phenom II 910e has a x13 multiplier. That small bump in the multiplier is what accounts for the 100MHz difference in the two processors. That means that the AMD Phenom II X4 910e has a final clock frequency of 2.6GHz with 2MB of L2 and 6MB of L3 cache. Not bad specifications for a processor that has a TDP that is nearly half the Wattage used on other popular Phenom II X4 processors!
