AMD E Series E-450 APU

The AMD E Series E-450 is an Accelerated Processing Unit based on Brazos Platform. The AMD E-450 supersedes the AMD E-350 and offers a higher clock speeds. There is a slight increase in terms of clock speed between AMD E-350 and E-450 from 1.6GHz to 1.65GHz. On the other hand the 80-core Radeon HD 6320 GPU glides up from 492MHz to 508MHz, not that great improvement though. What is good with AMD E-450 is its AMD Turbo Core technology. This means that the GPU (Graphics Processing Unit) cores in the E-450 can turbo up to 600 MHz, this means that the AMD E-450 can be up to 22% faster than the E-350.

The higher the rating the better the performance

The PassMark PerformanceTest permits you to quantitatively benchmark a PC using a variety of different speed tests and compare the results to other computers.

The AMD E-450 also supports DDR3-1333 unlike the E-350 that supports only DDR3- 1066. When this RAM speed is combined with the faster graphics processor or GPU you might appreciate expressively enhanced gaming performance out of the AMD E-450. This doesn’t mean that it will get anywhere near Llano's performance, but AMD promise a 36% increase in 3DMark Vantage performance.

It is found out, using many benchmarks / tests, that the AMD E-450 is superior than any other Intel Atom Processors available in the market nowadays.
