AMD E-300 vs AMD E1-1200

AMD E-300

AMD E1-1200

The AMD E1-1200 (codename Zacate) is a dual core processor for small notebooks and netbooks. It offers a relatively powerful integrated graphics card and a single channel DDR3-1066 memory controller. Compared to the old E-300, which is based on the same chip, the E1-1200 offers a 100 MHz higher CPU clock rate.

Inside the E1-1200 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-300 lies a bit beyond a Athlon X2 L310 at 1.2 GHz. 

The integrated Radeon HD 7310 graphics card offers 80 shaders and an UVD3 video processor. Compared to the slow GMA 3150 in the Atom processors, the HD7310 offers a lot more performance and is about as fast as the Nvidia ION graphics solution. In the E1-1200 the 7310 is clocked at 500 MHz and therefore not much different to the HD 6310 (488 - 500 MHz depending on the APU).

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.
