I have a 3-year-old laptop with a 1st gen I7 cpu (specifically model 740QM 1.73GHz). Will I see a large performance difference upgrading to a new laptop? What should I look for regarding features in a current CPU model to ensure an improvement? Jon

In terms of general overall performance the average increase based on combination of various applications, games and synthetic (least reliable) benchmarks by generation is as follows (assuming the same clockspeed):

1st gen Nehalem (Bloomfield / Lynnfield) -> 2nd gen Sandy Bridge = 12%
2nd gen Sandy Bridge -> 3rd gen Ivy Bridge = 6%
3rd gen Ivy Bridge -> 4th gen Haswell = 6%

Overall performance increase from 1st -> 4th gen = ~26%

Besides everyday typical user stuff, I also edit video, images using Photoshop, and some software development (mostly in Java).

The link below gives an overview of the features of the CPU. Hope this is what you are looking for:

Thanks for the input. It sounds like the consensus is for a large improvement. I looked up "Haswell" online. Is this just the latest Intel product line or is it a specific sub-group of the product line?

Assuming the same clock speed AND core count.

So the true bump will be considerably more from like the I5 760 to the 4670K at stock.
