The 5th generation is mostly just a die shrink, which usually means similar if not same performance, but less battery usage.
Hmm having the 4500u I was expecting more of a performance leap to the 5500u than this. While I did not expect to be blown away, I was hoping to see a bit more cache and a few more features from this new 5th gen series chip over the now aging 4th gen chip.
From what I've gathered, it's due to the limits of Moore's Law. AMD and ARM fair similarly year per year now as well.
Hmmm only a few percent performance benefit across i7-3517u, 4500u and 5500u series for a few percent TDP drop; representing 3 years of development at the same price point. The integrated graphic capabilities have gone up from very bad to fairly bad however. I guess intel spent all their R&D budget on their sales team bonuses or something. Hopefully some competition from more powerful ARM RISC-based moblie devices, or laptops with newer AMD-x86 chips will push microprocessor progress forward in the next few years, but i doubt it. Seems like price reductions and retailer promotions will dominate any decision to upgrade, rather than any real benefit in investing in newer processor generations. I'll wait to see what summer deals are on before buying. I am dissappoint :-(
