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.

Fairly certain it's 64MB on more than one of them.Ryan Smith - Wednesday, June 3, 2015 - link
All GT3e parts have 128MB of eDRAM. Did we mess up and put the wrong value at some point in this article?patrickjp93 - Thursday, June 4, 2015 - link
No, you're right. 64MB version of Crystalwell is coming to Skylake only as far as I'm aware.Laststop311 - Wednesday, June 3, 2015 - link
Wow Intel wont even let AMD keep the better iGPU performance crown. At least APU's had higher gaming performance going for them. Now they really have nothing. Plus this part uses less power and runs cooler than amd's igpu. Intel's engineering and process advantage is really showing. If I was building an HTPC this chip would be my go to. Can actually play any game with decent settings on it. Turn ur HTPC into a console PC gaming machine as well.The_Assimilator - Wednesday, June 3, 2015 - link
"Now they really have nothing."Couldn't have put it better myself. APUs were AMD's last card, and Intel just took that card out vof AMD's hand. If Zen isn't the second coming that's been promised (and I doubt it because of AMD's marketing track record), then AMD's CPU division is effectively dead.

That's what Anandtech would have people believe. In reality the FX chips like the $100 8320E (I paid $133.75 with an 8 phase power motherboard from Microcenter) is very competitive for things like h.265 encoding, Blender, and so on with Intel -- especially on performance per dollar.So, Anandtech sticks 6 APUs in its charts and not a single 8 thread FX chip.

Example... top scoring APU in Cinebench multithread: 3258 thread FX at just 3.33 GHz: 540
at a more reasonable 4.28 GHz: 683
4.56 GHz: 724
4.78 GHz: 765

I love it that you have a Linux section and I was even pleasantly surprised to see Redis benchmarks, which I use a lot! For my purposes I'm investigating using:1. MAXIMUS VII IMPACT MINI-ITX board (because it's the only ITX on the market afaik that supports M.2 x4. Other ITX boards seem to only support M.2 x2 although they often don't make it clear.)
2. Samsung XP941 128GB
3. M350 ITX case
4. Fedora 22 OS

"Samsung XP941 128GB" - a bit small I think - best to get 256GB straight away.boozed - Wednesday, June 3, 2015 - link
A salient question perhaps, but I wouldn't go calling it a poignant one.
