This is where you can fast forward to the final section of the review, and get a quick recap and points on the Intel i7-5775C.


What's Hot


Intel Delivered What the Community Demanded: Almost three years ago news broke that Broadwell would only be BGA, and not be a socketed desktop CPU. The community protested and Intel took note, and now they have delivered. The launch of the 5775C and 5675C shows that the community can make a difference. Intel should be applauded for listening to the DIY market. Even better, Intel made strides to provide Iris Pro and unlocked CPU in the same package.


Fully Unlocked CPU with Powerful Iris Pro Graphics and eDRAM: This is the first time Intel has paired an Iris Pro iGP core with an unlocked CPU. That is not to say you cannot overclock and tweak the iGP, you definitely can. The 5775C is a perfect fit for those who need a less expensive graphics solution, but not just the bare minimum.


Low Power Operation: Broadwell is great with power efficiency, especially considering the Iris Pro iGP. The die shrink, modified FIVR, and overall mobile design results in lower power consumption in the same performance envelope when compared to the 4770K. Broadwell also has a new standby power supply for very low power standby operation.



Excellent Integrated Graphics Performance: The integrated graphics might be one of the most powerful in the world (I haven't reviewed AMD's latest offering yet though). It's leaps ahead of the typical Intel HD series integrated graphics found on other unlocked CPUs. The Iris Pro 6200 with 128MB eDRAM helps to further bridge the gap between integrated graphics and discrete graphics for light gaming. The iGP implementation on the 5775C makes sub $100 discrete video cards pretty much obsolete. It also can be overclocked.


Overall good performance: While the 4770K is 200MHz faster and has 2MB more cache, the 5775C has much lower power consumption with much beefier graphics and performs pretty much head to head when both CPUs are clock for clock. Broadwell is less about IPC improvements and more rather about fine-tuning the CPU to maintain performance with a significantly lower power envelope.


What's Not


Lower Overclocking Margins than its Predecessor: While Intel listened to the consumer and did its best to modify Broadwell by unlocking it and optimizing the CPU for the desktop, overclocking margins aren't what many expected. While you will be able to hit that 4GHz-4.2GHz mark, going far north of it can be cumbersome. You shouldn't expect the crazy memory overclocks that Haswell provided, rather modest ones using XMP. Ticks don't always overclock as well as Tocks, and while Broadwell is an example of this, it isn't alone. Ivy Bridge also had overall lower overclocks than Sandy Bridge.


Timing: While Intel launched the 5775C and 5675C SKUs at Computex, they also announced that the next generation 100 series platform would be coming this year. This puts the 5775C and 5675C in a tight spot, as many are intrigued by what Intel has to offer later this year.



Final Thoughts




The price of the 5775C is higher than the 4770K and 4790K, but I think that is justified with the Iris Pro graphics. One thing is clear, if you need that iGP to be fast, then Intel's 5775C is perfect fit for you, but if you are looking for high overclocks and you will use a discrete GPU, then perhaps it might not be the best fit.


The elephant in the room is that many overclockers and DIY enthusiasts never use integrated graphics, but there is a large portion of the population that uses the iGP. You shouldn't think of the 5775C as an overclocking CPU with high-end integrated graphics, but rather as an efficient and fast desktop CPU that happens to allow tweaking and carries a powerful integrated graphics processor.
