For 17" mbp model....
Is CPU upgrade 2.2-> 2.3 worthy? (250USD/1950HKD)

i7 2720QM -> i7 2820QM
cache: 2MB More
CPU: 0.1 GHz More per core

thx for your time for reading this post >v<!!

Depends how intensive your tasks are. But for most people, no. Not worth it.

 

[TMRaven]

No.

The major thing you are getting with the 2.3GHz processor is not the additional 100MHz of clock speed, but the additional 2MB of cache (8MB vs. 6MB), which will offer better performance in certain tasks. This was the main difference in the i5 and the i7, the cache offerings. The top-spec 2.3GHz offering will give you the maximum 8MB of processor cache which might give you an advantage when doing something very intensive such as compressing video or motion 3D animation rendering.

I am going to use it to write and compile iOS apps, render 1080p movies, and run VMs.

Probably involve 3D drawing for writing games.

Installing a 128gb ssd in it instead and investing in an external hard drive would be the smarter move. Especially considering that they now use thunderbolt, you'll eventually see some externals that use it.

Not worth, if you need more speed get an SSD.

You will probably never notice the extra 2Mb of cache, and the 2.3 is only 4% faster than the 2.2

So your videos will render 4% faster, or maybe a bit more if the cache increase helps at all, call it 5%. If you have an hour render, is it worth it to save 3 minutes? Probably not. I would save the money for stuff you will need, like bigger or faster disks (maybe a nice LightPeak enclosure for them) or a SSD or more RAM.

Just fixed that for you

It just sounds silly calling it that. Thunder doesn't come in bolts.

Thunderbolt refers to the lightning, i.e. that bolt that you see when you hear thunder.

Or, the ominous clap of thunder you hear when you see the price tag.

Nope.
