New MacBook speed compared to the old one

[beneventi]

Dear guys, I've just purchased a new 2.0 GHz unibody MacBook that is about to arrive in a week.

My question is: how can it be compared, in terms of speed and heat consumption, to the old model I own (late 2006 black MacBook with core 2 duo 2.0 GHz processor) in the real life tasks? I would like to know if the new architecture (larger cache, faster front side bus, faster memory, new chipset) give it sensitive higher performances even if the frequency is the same.

I use my Mac as a developer, both on OS X and Windows with BootCamp (I'm a .net developer) and would like to hear your opinion. I do not play games.

Best regards

Alessandro

For those tasks, you probably won't see that much difference until Snow Leopard comes out.

Conclusions

Somewhat suprisingly, processor performance is virtually unchanged in the new MacBooks and MacBook Pros; the new NVIDIA chipset and the faster DDR3 memory haven’t managed to help increase processor performance.

...Does this mean the new laptops are a bad upgrade? Hardly! While the NVIDIA chipsets might not be as good as the Intel chipsets when it comes to processor performance, they far surpass Intel when it comes to graphics performance. This increased graphics performance is a huge gain for the MacBook, and makes the MacBook a compelling machine for people looking for a smaller MacBook Pro.

I definitely noticed a BIG difference in day-to-day stuff when I moved from my 1.83 CD whitebook to the 2.0 unibody. Everything about the system seemed faster. I upgraded to the 2.4 aluminum and the difference between that and the whitebook is pretty substantial. The Unibodies also seem to run much cooler than the plastic models.

I would like to point out that the 2.4 MB out performed the 2.4 MBP. Why is that?
