Intel Atom N2800 vs AMD E2-2000 vs AMD E1-1500

Intel Atom N2800

AMD E2-2000

The AMD E2-2000 (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 E2-1800 offers only slightly higher CPU (50 MHz) and GPU (15 - 20 MHz) clock rates.

Inside the E2-2000 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 E2-2000 is a bit below 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, clocked at 538 - 700 MHz, 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 power consumption is rated with a TDP of 18 W by AMD. That's about the same level as Intels (significantly faster) ULV CPUs.

AMD E1-1500

The AMD E1-1500 (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 old E1-1200, which is based on the same chip, the E1-1500 offers an 80 MHz higher CPU and 29 MHz higher GPU clock rate.

Inside the E1-1500 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 E1-1500 is a bit below an 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 E1-1500 the 7310 is clocked at 529 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 W by AMD. That's similar to Intels (faster) Ivy and Sandy Bridge ULV-CPUs.
