Intel Broadwell i7 5775C Review & Overclocking
Integrated graphics have come a long way since their earliest incarnations. Once upon a time they were so poor they were really only useful for displaying your desktop, and anything more demanding was too much for them to cope with. Since then we've seen the insane eye-candy of the latest generation consoles powered by the AMD APUs. Nobody is pretending that a PC will ever be as light on the overheads as a console so we're not remotely expecting image quality at those levels, but on the flip side they (the PS4 and XBone) show what is possible.
The Intel HD4600 graphics that came as part of the Haswell CPUs was the first indication that, in gentle titles at low detail settings, it was possible to go entirely without a dedicated GPU.
Today we're looking at the i7-5775C, a CPU that comes equipped with the very latest iteration of the Intel iGPUs, Iris Pro Graphics 6200. There are plenty of models of CPU with this new set of graphics but we felt it was important to be able to compare like for like, so the quad-core, hyperthreaded i7-5775C matches up against our i7-4790K.
The importance of seeing the die is generally something that every review includes but most of us ignore. It's a feature that is cool if that's your area of expertise, but the majority of us just care about the end product. We've included it today because just look at how much of the die space is taken up with the Iris Pro 6200. The benefit of the 14nm process is how much room is left over and the designers have met the challenge with relish and stuffed as much GPU on as possible.
It's good to see that Intel are releasing so many CPUs with the Iris Pro Graphics 6200 included, particularly as we can't imagine too many people having the budget for the i7-5775C but not willing to get a value dedicated GPU.
As always with a new product there are loud promises of big performance increases. That's exactly what we're here to discover though, so is the i7-5775C a match for the more mature i7-4790K? And, more importantly, how does the Iris 6200 stack up against the HD4600?
