Intel Atom N2800 vs AMD E2-2000 vs Intel Atom N2650

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.

Intel Atom N2650

The Intel Atom N2650 is a dual core entry level processor for netbooks and tablets. It was officially announced in January 2012 after some troubles with the graphics drivers (according to rumors). 

The N2650 features a PowerVR SGX545 based graphics card (at 400MHz) named Graphics Media Accelerator 3600 and a video decoding engine for MPEG4 Part2, VC-1, WMV9, and H.264. Furthermore, the chip now also supports DisplayPort 1.1 and HDMI 1.3a outputs.

The processor core should be still similar to the old Atom processors. Therefore the performance of the N2650 should be a little bit over an older Atom N570.

The integrated 64Bit Single-Channel DDR3-800/1067 memory controller supports two SODIMMS and a maximum of 4 GB RAM.
