I'm looking for some advice. Do people think it's worth it to spend $70 more to get the i7-4500U instead of the i5-4200U? I can get the Lenovo Z40 laptop with either one (through the Barnes & Noble gold discount) and it's $70 more for the i7-4500U.
Why in the world do you not compare the one very important point... price?? price-performance ratio would show a large jump in price for only moderate (minimal?) gain in performance.
when I bought a laptop with core i3 I thought the same about it "the best processor in my life" lol
my ultrabook K451L B Asus cpu is Core i7 4500u, but turbo clock speed is 2.4Ghz !! what can i do to improve turbo clock speed to 3Ghz ?
the i5 is the best i had of my life
I think the value of the items in the "memory controller" is wrong
no not worth it. 1MB L3 Cache (512k per core) is not worth $150. CPU speed is negligible. 300mhz difference won't make that much of a difference unless you're rendering/encoding by large quantities. In which case, you're better off getting a quad-core. Unlike desktop, where you pay $100 more for an i7, but you get better features such as hyperthreading. I think it is a marketing gimmick to call the 4500U a "i7". In the real world, it would be called an i5-4500U :p
This is the same question I had..
Are the I7 advantages worth $150 more in cost though? I don't think you will see much difference in real world applications.
Thanks - both these are options in the Dell XPS-12 Convertible
