AMD E2-1800 VS. AMD E1-1200 Accelerated Processors

Two new Brazos 2.o Accelerated processors are now available in the computer market for netbooks and low-budget laptop PCs, the AMD E2-1800 and the AMD E1-1200 which are intended to replace older Accelerated processors, the AMD E-450 and E-300 respectively.

The AMD E2-1800 APU features level 1 cache of 128kB and level 2 cache of 1024 kB and runs at a clock speed of 1.7 GHz, this is higher by 50 MHz compared to older AMD E-450 with a clock speed of 1.65 GHz. With regards to GPU, the AMD E2-1800 accelerated processor has an integrated graphics controller called Radeon HD 7340 that features 80 shaders and an UVD3 video processor. It also has a Thermal Design Power of about 18 watts which makes it suitable for smaller to large notebook PCs.

On the other hand, the AMD E1-1200 APU offers 1MB level 2 cache, and 128 KB L1 cache and runs at the clock speed of 1.4GHz, this is slightly slower than AMD E2-1800 by up to 250MHz. For GPU side, this AMD E1-1200 APU features Radeon HD 7310 which is clocked at about 500 MHz. Just like the AMD E2-1800, this APU has a TDP of 18 watts.

With regard to CPU, the AMD E2-1800 has a PassMark rating of 795 this is higher compared to E1-1200 with just a rating of 577. On the graphics side The Radeon HD 7340 runs at the clock speed ranging from 523 - 680MHz while the Radeon HD 7310 found in E1-1200 has a clock rate of about 500MHz. This only means that the AMD E2-1800 has quite a better GPU compared to E1-1200. Both GPU supports DirectX 11 technology.
