AMD E2-1800

The AMD E2-1800 (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-450, the E2-1800 offers only slightly higher CPU (50 MHz)  and GPU (20-80 MHz) clock rates.

Inside the E2-1800 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 7340 graphics card offers 80 shaders and an UVD3 video processor. Compared to the slow GMA 3150 in the Atom processors, the HD7340 offers a lot more performance and is about as fast as the Nvidia ION graphics solution. The difference to the older 6320 in the E-450 is a 20-80MHz higher clock rate.

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.
