comparing 4th Generation Intel Core i7-4710HQ vs 5th Generation Intel Core i7-5500U

[intelli9]

4th Generation Intel Core i7-4710HQ Processor (2.50GHz 1600MHz 6MB) vs 5th Generation Intel Core i7-5500U Processor (2.40GHz 1600MHz 4MB)

It looks Intel Core i7-4710HQ has much higher performance. However, Intel Core i7-4710HQ is 2014 and Intel Core i7-5500U is 5th generation.
I am not sure how much difference generation would reduce gap between.

My question comes from comparing two of laptops.
Can you recommend which one will be more reasonable with the price?

Take the $899 configuration of the second link. The extra GPU and CPU horsepower should be worth it.

5th gen 5500u is dual core and has 4MB cache

4th gen 4710Hq is quad core and has 6MB cache

4710HQ is almost 1.4x better than 5500u.
