If i get it right... you are trying to find a CPU for a laptop right? I am sorry to inform you that CPU in a laptop cannot be changed. Few of the components of a Laptop, the CPU , GPU and Motherboard cannot be upgraded or changed for some other model.
You can decide which CPU you want the first time you buy the laptop, there are different laptops available with different type of CPUs and they cost differently depending on what kind of CPU you buy (Higher Performance CPU = Higher Price). But once you have a bought a laptop you cannot change the CPU or GPU. you can only change Ram or Hard Drive, but nothing else to increase performance.
I would suggest to sell your current laptop and use the money to buy a new laptop one with a CPU you think would do well for the performance you want. People on forum can help u in choosing the best laptop you can get for your budget.
That is a completely wrong answer -- did you even look at the laptop in question before responding?
The K53Z processor is socketed, and fairly easily changed. Since it's an AMD APU, not only are you upgrading the CPU, but also the GPU at the same time. It makes a huge difference to this machine -- the A4 is both a weak processor and a crippled GPU, with half the available shaders disabled.
Swap out the A4 for an A8-3520M; it's an upgrade to a much more powerful quad core and a graphics engine that absolutely kills Intel based chip graphics. There are no issues with heat, battery life, or anything else with this upgrade. Cheap, too -- found one for $20 bucks! Add an SSD and you found yourself a nice ultrabook for cheap.
