The link is fixed now. BTW, Silent PC Review has at least 1,000x more credibility than you happen to have. Care to link to some of these "others", or are we talking about posters on other forums/these forums?
let see,
First off all the results are from the Core i7 6700K, the Pentium HD530 is 10-20% slower.
Secondly, they used DDR-4 2666MHz memory on the Core i7 and only 1866MHz on the A8-7600.
Thirdly, no driver version to be found anywhere. That is because they used the original
February 2014 A8-7600 review results in the
Core i7 6700K review posted on September 2015. That makes them 1000 times more credible than me
Also, those games are more than 5 years old (Crysis released 2007, Resident Evil 5 demo released on 2008 etc) with many of them being DX-9/10 which are more CPU bound than iGPU at 1600x900.
In newer games (DX-11/ Mantle and DX-12) that really need more iGPU performance, the Kaveri A8-7600 iGPU is 30-50% faster than HD530 found on the Core i3 6300 when both are using 2133MHz Memory.
