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.

| DRAM | G.Skill RipjawsZ 4x4GB DDR3-1866 C9 at DDR3-1600 |
| Low End GPU | Integrated ASUS R7 240 2GB DDR3 Dual Graphics with R7 240 |
| Mid Range GPU | MSI R9 285 Gaming 2GB MSI GTX 770 Lightning 2GB |
| High End GPU | MSI R9 290X Gaming LE 4GB ASUS GTX 980 Strix 4GB |
| Power Supply | OCZ 1250W Gold |
| Storage Drive | Crucial MX200 1TB |
| Operating System | Windows 7.1 64-bit, Build 7601 |
| CPU Cooler | Cooler Master Nepton 140XL CLC |
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.

Not really sure how appealing this will be for anyone on LGA1150 for the desktop, given Skylake is just around the corner. Certainly more appealing to heavy duty laptops, maybe NUCs for the better GPU capabilities but the prices are too high compared to low-end CPU + dGPU options (Alienware Alpha at $400-500 comes to mind).CuriousBeing - Tuesday, June 2, 2015 - link
I could never understand why the FX-8350/FX-8370 are never used in these benchmarks....Refuge - Tuesday, June 2, 2015 - link
It is probably because of the new test setup. They haven't re-run everything yet.Not that I consider that a good excuse, I know they are busy though and it is an answer to your question at least if that helps. :P

Broadwell is not for users who want high integrated GPU performance or something like thatIt's an upgrade root for many with Haswell

Ian, buddy, you really need to step up your game when it comes to analyzing power, temperature, and noise. Seriously, Anandtech used to be a place where you could read a review on a product and have all the information you needed about it and now once i'm done reading an Anandtech review i have to look elsewhere to get the full story.Old Anandtech: Comprehensive and comprehensible.
New Anandtech: Comprehensible only because the reviews have become utterly incomprehensive.
Step it up buddy.

A bit harsh, but agree with the point. I'm now waiting (hoping) that somebody at Ars or TPU gives a more comprehensive review.This Delta power consumption shit has to go as well.

So the actual CPU part takes up less than half the die. My forehead cannot take much more of this, there are just to many facepalms these days.And this is what they want us to pay $276 for - a CPU that would take up much less than 100 mm2 and should cost $100.
God, please, let Zen be a good CPU, please. I will pray every day, I want Haswell to be my last Intel CPU for a long time.
I would just like to point out, than an i3 with a 750 Ti will destroy this APU, offering PS4 performance in every single game, for pretty much the same cost.

Don't expect Zen to be a some "cheap chip" AMD has stated they're going to focus on performance rather than cost. I'm expecting Zen with HBM to cost as much as comparable Intel offerings.Rather than complaining about the cost of new cutting edge hardware, put your money where your mouth is and get the i3 + 750TI. I have one here and it serves well as a secondary machine (as well as a doorstop). I'd much rather use my 2500K + 960...

I'd really love to see benchmarks of Civilization V on this thing. With such a CPU-intensive game, it'd be interesting to see how much the L4 cache makes an impact, not just with integrated graphics, but also when using dedicated graphics, to see how much the L4 cache helps the raw CPU performance in a game that is so easily CPU-constrained...Peichen - Tuesday, June 2, 2015 - link
I think Civ 5 is still single thread or maybe dual thread and have to process everything in order so each term still take minutes. I have the game at launch and all packs & DLCs and it doesn't stress my overclocked 3770K a bit. No core hits above 40% yet a term still takes forever. The game isn't 64-bit either so there is also that.
