PCWizKid remembers one year ago when the first AM3 processors were launched. How far we have come that the manufacturing technology permits us to take advantage of lower power consumption and energy efficient CPU's. Today we take a look at the latest addition to the AMD Quad core "Deneb" family of CPU's with the Phenom II X4 910e. Previously we reviewed the Phenom II X4 810 which is has the same Deneb die clocked at 2.6GHz, however it has a TDP of 95 Watts. The "e" in the 910e stands for "energy efficient" and for that reason has a TDP of only 65 Watts, while having the exact same frequencies. As expected, this chip is manufactured with a 45nm process, and supports AMD’s AM3 platform. The aim of this CPU is to run things in a cooler and quiet PC while still getting the same if not better performance. This CPU is not a black edition however and as such it is not meant for extreme overclocking. PCWizkid does a review to test just that, how efficient the 910e is, and the performance it delivers using less energy.
A quick update, along with the launch of the Phenom II X4 910e in January 2010, AMD has additional updates on its dual, triple and quad-core processors while dropping prices of others. This is what AMD has released so far this first quarter of 2010:

Testing Notes:
- Ambient room temperature 20C or 68F - All tests are performed at 1280x1024 resolution for consistency in results and comparisons with other system tests. - All tests are using real world conditions with all components in a computer case closed and not with side panels open or with a open test bed. PCWizKid's test conditions makes the results more accurate.
Game settings for benchmarks are always maxed out at either Very High or Enthusiast levels when available.

Conclusions
AMD has created a 65W series of Phenom II X4 CPU which fits the green computing movement of today. The Phenom II X4 910e keeps with what is nominally a high-performance CPU within that small thermal envelope helping lower total system power consumption while not skimping on performance. PCWizKid was impressed at the low temperatures and the ability to squeeze an additional 500Mhz without increasing the core voltage. This meant getting more performance for less than other Phenom II X4's keeping it cool and quiet. While this is a new AM3 socket CPU, AMD knows that If your needs are for a performing quad core CPU and you have a older AM2+ motherboard you can save purchasing a new AM3 motherboard and reuse your older board which makes this a economical CPU in the long run which can be upgraded later to a newer AM3 socket motherboard.
