AMD E Series E-300 APU

Another Accelerated Processing Unit (APU) coming from AMD is the AMD E Series E-300. The AMD E-300 is the upgraded version of the single-core AMD E-240. The AMD E-300 APU is consists of two Bobcat cores which means that the new E-Series APU are all dual-cores. The CPU clock speed is down by a bit compared to E-240, it has a clock speed of 1.3GHz compared to E-240’s 1.5GHz but we all know that the clock speed is not the only basis to measure the overall performance of a CPU but also some other things like the number of core it has.

In graphics side the GPU clock of the E-300 also drops by a bit to 488MHz compared to E-240’s 500MHz but both have an ATi Radeon HD 6310 GPU that can play high-definition videos with ease. Regarding the battery life, the E-300 APU with a 6 cell battery should be around 4-5 hours.

The higher the rating the better the performance.
