I got the 6700hq today. 16GB ddr4, nvidia gtx 950, 1Tb hhd+128ssd, lenovo idea pad. Wish I could have afforded thinkpad upgrade... also the 7700hq is wayyyyy overpriced
its not, the 7500u is duel physical cores just like the 6500u the 6700hq is the quad core. the u is the notebook processer that uses much less energy than the hq versions and therefore is used in more portable notebooks and not gaming laptops that don't need the battery life. as with all i7s these all come with hyper-threading so the u series has 4 logical cores and the hq has 8 logical cores
Why is i7 6500u a quad core and the i7 7500u dual core? I know each core has two blah blah but 7500u says dual core when 6500u say quad core
it does, it just also has a vestigial DDR3-L controller as well
That's odd, I think the i7-6500u runs on DDR4 as well..
7500u is superior!
