Conclusion
Such is the importance of the Iris 6200 graphics that we've strayed from our usual format to bring you today's review. Usually we're only interested in how much performance can be squeezed from a CPU and how high the overclocking will go. At the risk of stating the obvious the sign on the door says Overclock3D and that's our ideology. The amount of performance available from integrated solutions has always been so low, and the improvement from even the cheapest GPU so high, that we've never really bothered with iGPU performance.
The Core i7-5775C is interesting because it's the first 14nm processor we've seen from Intel. It's the forerunner to the Skylake CPUs that most of us are patiently awaiting. The performance from it is not far behind the faster i7-4790K Haswell CPU that we've put it up against and although we couldn't obtain more than 4.2GHz from overclocking it, we're sure that more mature BIOS' will allow us to push it further. We can't wait forever though, so rather than delay our review we put them against each other at stock. The reduced nm process enabled the i7-5775C to be extremely efficient both thermally and in overall power draw for the system at the wall.
What the die size reduction has meant is that there is, as you saw on page one, enormous amounts of space left over to fill up with the Iris Pro Graphics 6200. And what a job Intel have done too. The performance of the Iris 6200 is phenomenal. So good we struggle to believe it, but it isn't a case of it only being good at one or two things, but rather it happily munched through everything we threw at it. You aren't even reliant upon lowering the detail settings to minimum either. On what we call 'medium' settings - which are exactly that - the i7-5775C still banged out some very high frame rates. In 3D Mark Ice Storm for example we saw results akin to a GTX650Ti. From a CPU. If that doesn't leave you open-mouthed in amazement then maybe you're beyond help.
There is, of course, a slight caveat. Namely that this particular CPU probably isn't best suited for the integrated graphical goodness the Iris 6200 provides. If you can afford to purchase an i7-5775C then you are probably looking to buy a dedicated GPU too. Or at least should be. Instead the Iris would be most at home on an i5 or even an i3. A dual-core £100 i3 with the 6200 graphics would be perfect for the laptop, HTPC or maybe even the AIO PC crowd and we wait with eager anticipation for this amazing graphics solution to find a home on a CPU more suited to its low-power, high performance audience. If for arguments sake an £100 i3 with Iris 6200 graphics was released it would pretty much render every AMD APU pointless and we have a funny feeling this is where Intel is heading in the not to distant future.

because i want to upgrade from a 3570k cause I´ve been having some issues but for me a iGPU isn´t really needed.Quote
