AMD E-450

The AMD E-450 (codename Zacate) is a dual core processor for small notebooks and netbooks. It offers a relatively powerful integrated graphics card and a single channel DDR3-1333 memory controller. Compared to the older E-350, the E-450 offers only 60MHz more clock speed, but a faster graphics card (thanks to Turbo Core) and DDR3-1333 and HDMI 1.4a support.

Inside the E-450 two Bobcat cores can access 512KB level 2 cache per core. In comparison to the Atom processors, the Bobcat architecture uses an "out-of-order" execution and is therefore faster at the same clock speed. However, the performance is far worse than similar clocked Penryn (Celeron) or Danube (Athlon II) cores. On average the cpu performance of the E-450 lies a bit beyond a Celeron SU2300 at 1.2 GHz or a Athlon II Neo K325 at 1.3 GHz. 

The integrated Radeon HD 6320 graphics card offers 80 shaders and an UVD3 video processor. Compared to the slow GMA 3150 in the Atom processors, the HD6320 offers a lot more performance and is about as fast as the Nvidia ION graphics solution.

The power consumption is rated with a TDP of 18 Watt by AMD. According to first reviews of Brazos prototypes the power consumption was between 11 to 29 Watt. This would be on a level of a (much more powerful) 11" MacBook Air using Windows 7.
