Intel Core i7-5775C Review

Introduction

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.

What's New?

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?

So, Intel made a GPU. Great, put it on an i3, just give me a real processor... If I'm buying a top of the line chip, it's pretty safe to assume I won't be using the integrated graphics.Quote

I´m waiting for ZEN and then compare only the raw CPU power.
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

Holy smeg-o-rama! That iGPU is stonking, kudos Intel kudos indeed.Quote

jeesh how much die area are Intel wasting on they're flaming integrated GPU's ? intel we mainly want CPU's from you - not GPU's? I don't care about integrated graphics in desktop processors ? your spending so much energy on something, no one asked for? whose ambition is this ? wheres the cheap 8/16 core processor there should be here - by now ? instead at 14nm were still at quad core, the same as my 65nm q6600 processor wayback when ? a 4x reduction in process should mean if we have the same wafer area attributed to each die, 64 cores by now ? in very rough theory? if you just scaled down the q6600 transistor count cpu layout to the 14nm scale on the same die area as a q6600? (square area rule?) your deliberate failure to focus on more cores or the CPU portion of the processor transistor count, is beginning to be aggravating in the extreme ? moores law has been broken for 8 years and you have not really delivered imo much CPU performance increase. Everyone but a minority seems unaware or happy with the status quo performance wise youv'e been delivering? that consumers have been roughly receiving the same quad core power with small performance bumps for a long time, you may not have allot of competition from AMD but you've been taking the mickey compared to your illustrious history of performance increase in the past. and yes more cores don't always translate to more performance in individual programs depending how they're written, compared to higher frequencies etc, but lets be honest running many programs at once is smoother with many more cores. if any CPU manufacturer delivered a non iGPU CPU and threw down the CPU performance hat once more it would be interesting to see what could really be offered at this process scale ?Quote
