The Intel Broadwell Desktop Review: Core i7-5775C and Core i5-5675C Tested (Part 1)
by Ian Cutress on June 2, 2015 7:45 AM ESTTest Setup
As we mentioned in our introduction, Intel's 9-series chipset were designed from the start to allow future compatibility with Broadwell. As a result with a BIOS update we're able to drop these processors into our existing MSI and ASUS Z97 boards, though not without some pre-release BIOS teething issues.

Many thanks to...
We must thank the following companies for kindly providing hardware for our test bed:
Thank you to AMD for providing us with the R9 290X 4GB GPUs.
Thank you to ASUS for providing us with GTX 980 Strix GPUs and the R7 240 DDR3 GPU.
Thank you to ASRock and ASUS for providing us with some IO testing kit.
Thank you to Cooler Master for providing us with Nepton 140XL CLCs.
Thank you to Corsair for providing us with an AX1200i PSU.
Thank you to Crucial for providing us with MX200 SSDs.
Thank you to G.Skill and Corsair for providing us with memory.
Thank you to MSI for providing us with the GTX 770 Lightning GPUs.
Thank you to OCZ for providing us with PSUs.
Thank you to Rosewill for providing us with PSUs and RK-9100 keyboards.
Load Delta Power Consumption
We'll start things off with a look at power consumption. Power consumption was tested on the system while in a single NVIDIA GTX 770 configuration with a wall meter connected to the OCZ 1250W power supply. This power supply is Gold rated, and as I am in the UK on a 230-240 V supply, leads to ~75% efficiency > 50W, and 90%+ efficiency at 250W, suitable for both idle and multi-GPU loading. This method of power reading allows us to compare the power management of the UEFI and the board to supply components with power under load, and includes typical PSU losses due to efficiency.
We are reporting the power consumption difference when idle and during an initial OCCT load. This is slightly skewed by the adjustment up the efficiency chain of our power supply, showing lower power CPUs consuming a little more, but despite this the qualitative comparison is a still a good place to start.
Despite our test being almost qualitative, it is exciting to see that in our power consumption limit test both CPUs score around their TDP values.

Hahaha.."lay the smackdown"..on Broadwell's candy A#$..! good one ;)Asomething - Tuesday, June 2, 2015 - link
So can you guys include 2400mhz ram in part 2 gaming benchmarks? it would be interesting to see what both sides gain from the faster ram.bobjones003@gmail.com - Tuesday, June 2, 2015 - link
Well I see no reason to upgrade yet maybe when skylake drops. My sandy bridge(i 5 2500k) will go for another generation. The cpu runs overclocked to 4.7 ghz at this I could save boat load of power on the system.Shadowmaster625 - Tuesday, June 2, 2015 - link
This review is also bunk due to the fact that they are usign a DDR3 card when even the same card with GDDR5 is way faster and only marginally more expensive. No one in their right mind even buys a gpu with DDR3 onboard.bloodypulp - Tuesday, June 2, 2015 - link
5 Years after the first AMD APU with graphics on-die, Intel finally has graphics on die.Well done Intel. *slow clap*

And AMD market share on CPU and GPU have been going from what to what in those 5 years? Kinda like how Bulldozer was the first "true" quad-core but managed to run at 60% of the speed of "fake quad" Q6600 and being hot as hell.bloodypulp - Tuesday, June 2, 2015 - link
Process advantage, much of it.olafgarten - Tuesday, June 2, 2015 - link
Technically Intel did graphics on-die first, they did it back in January 2010 with HD Graphics on the Clarkdale and Arrandale. It was in June 2011, when AMD released their first APU.Ryan Smith - Wednesday, June 3, 2015 - link
Clarkdale was a separate GPU die, on-package with the CPU. Intel didn't integrate the GPU on to their CPU until Sandy Bridge in January of 2011.HotRod917 - Tuesday, June 2, 2015 - link
Hey whats the whole"Thank you A for X
Thank you B for Y"...huh, whats goin on AT? Dare i say sarcasm towards manufacturer's being cry babies for not thanking them enough.
And speaking of manufacturer's...AMD its high time u pull a miracle (zen) and 'bring it, I mean the monopoly from the blue team is just ridiculous...for god sake AMD plz. Also ARM and Samsung ur welcome to join the desktop x86 party anytime..and the sooner the better.
Meanwhile i'll be rockin my delidded 3570k till skylake is out
