i7-6700HQ vs i7-6820HQ?

Hi, I'm thinking about buying a T460p:-

And I have to choose between the i7-6700HQ and i7-6820HQ (+£160). I can't exactly see a large difference between these two CPUs, can someone describe to me the differences so I can determine if it's worth the £160 upgrade? Thanks!

P.S. From my understanding both CPUs are limited to 35W, rather than their 45W recommended TDP.

Well there's no difference except the fact that the 6820hq has 100mhz more clock and has 2mb more cache.
The difference is probably around 5-10% increase in performance

I7-6700HQ has a passmark rating of 8046.
I7-6820HQ has a passmark rating of 8699.

I would find this cpu performance difference negligible.
Of much more importance would be to buy a SSD for windows. It makes everything you do much quicker.

Already got that down, 1TB 850 pro, 32GB of RAM, just the CPU I'm debating. Also kinda upset about the low-powered GPU but heyho you don't get everything in life.

Thanks guys! Gonna save the £160 and get the slightly less powerful CPU.

Yea.
Those are still pretty considering that my fx 4300 OC can only score 5600
