i5 to i7 upgrade

Apologies if this isn't the right place to post this question. I'm considering a processor upgrade and have no idea about them really. I'm thinking of going from my current VAIO's

"Intel® CoreTM i5-460M, 2.53GHz"

to something like this

"Intel Core i7 4770K 3.50GHz Socket 1150 8MB Cache"

I use the VAIO for programming and run Visual Studio, ReSharper and SQL Server and it can struggle. I already have 8GB of RAM and an SSD. The full version number is VPCS13V5E, graphics is Intel® HD Graphics.

Questions:

1. How do I find out if it's compatible?
2. Is it particularly difficult to swap out the processors on VAIOs?
3. Would going from i5-460M to i7-477K even be worthwhile? Would any other processors be better?

Thanks in advance for your help

 

Can not do that upgrade.

You need a new platform/motherboard for the newest processors.

(You are asking to upgrade from Arrandale to Haswell - 3 or 4 generations apart...).


Sorry.

 

What MAY be viable is the same generation i7-640m. That would give you quite a good jump in CPU grunt power. You would have to research this further though.

Thanks both for your replies. I've started to fish around for checking compatibility with an i7-640m and can use this http://processormatch.intel.com/compdb/ to check motherboard compatibility. Can't find the motherboard name on my order sheet and sony support don't recognise my model name (perhaps as it was a custom build). Are there any websites where you can look up motherboard names from model numbers or will I need to open the case?

 

The jump would not be THAT big, seeing as how they're both dual-core CPU's. If the laptop had dedicated graphics and supported booting without iGPU he could have considered a quad-core model such as the i7-720qm or above, but I have my doubts on that machine.

 

The first gen I-Cores unfortunately all have fairly low clocks. There is no Super huge jump even in quad cores as they are fairly low clocked. Good thing is as they all are clocked low any bin increase is large compared to IB's etc. Once you are over 3.0 GHz 100 MHz is very little, at about 2.0 GHz 100 MHz is at least 5% more CPU.

You could spend more if compatible and get a QM though as it may help with all those threads. Be warned even this may not get you where you want.
