Skylake: Intel's Core i7-6700K And i5-6600K

Results: Workstation Applications

The following benchmarks are based on AutoCAD 2015, Cadalyst 2015 and three modules of SPECviewperf 2015. They were specifically chosen to represent CPU performance, even though we have a GeForce GTX 980 installed instead of a workstation-class card.

AutoCAD 2015 2D And 3D Performance

AutoCAD is a popular application from Autodesk. First, we’re testing its "2D" performance with Cadalyst 2015. Quotes are used there because AutoCAD deals with 2D the same way many other applications do: through DirectX's D3D interface. This way of implementing 2D is worth testing since there really hasn't been any hardware acceleration for 2D through the kernel-mode driver since Windows Vista. Graphics cards with unified shader architectures don’t have dedicated 2D units anymore, either.

The finishing order in this benchmark is determined solely by the CPU, since the graphics card's performance goes unchanged. The two new Intel processors set a new bar in both metrics with similar 2D and 3D results.

Maya 2013

Viewport 2.0 isn’t part of our Maya 2013 results on purpose, since it’s based on DirectX. This means that this benchmark is based exclusively on OpenGL. The render modes used for this benchmark are shaded, ambient occlusion, multi-sample anti-aliasing and transparency, and the model consists of 727,500 vertices.

Showcase 2013

Showcase 2013 is another DirectX-based benchmark. Autodesk might be the only major developer to make the jump to DirectX, but many smaller companies are taking the plunge as well.

The model used for this benchmark includes eight million vertices, as well as render modes like shading, projected shadows and self-shadowing. In the end, clock rate and IPC determine the winners and losers.

SolidWorks 2013 SP1

SolidWorks 2013 by Dassault Systèmes is a classic. The different models for our workloads range in size from 2.1 to 21 million vertices. Individual tests use the software's many rendering modes, including a shaded mode, shaded with edges, ambient occlusion, shaders and environment maps. Compared to SPECapc for SolidWorks 2013, the CPU test is gone, the number of models is lower and a benchmark with parallax effects was added.

    Yawn... its easy to see that intel have to little competition, they have stagnated in the cpu performance department!
  • daniel266
    Can we have comparisons of rendering software using win 8.1 and win 10 ??

    Still 4 cores.... Im sticking to my Q6600.

    What the heck Intel? So, you provide great integrated graphics into Broadwell, then nerf it for Skylake? I guess you had to find a way to help sell your 'paper launch' of Broadwell. I really hope Xen makes you guys wake up; although it more than likely won't.
  • Bartendalot
    At least Skylake HEDT should be powerful. Unless DX12 pulls a rabbit out of a hat, this doesn't look promising for anyone who has Sandy or higher.

    Then you really are missing out, 4 cores or not a current i5 (let alone an i7) will simply destroy the old Q6600 C2Q. It was great in the day but it's very old hat now and the lack of features on the board worse still.

    You do know that your Q6600 is astronomically slower than Skylake in every single department, right? By your logic, the Phenom II X6 is better than the i7 6700K.

    I think you should consider upgrading. You won't regret, promise.

    Do you mean Shen, from LoL? Or Zen? XD

    I believe the cost of the integrated memory chips would make these processors too expensive and niche to be viable products.

    Good upgrade for 1st Gen i5/i7 users. Though I think they targeted it at the 2nd Gen i5/i7 users, doesn't seem like a huge improvement for them though.
  • vertexx
    Why no discrete graphics tests?
  • Cryio
    Skylake, the 1st worthy upgrade for Sandy Bridge users. If average IPC improvements from Sandy to Broadwell are ~13%, Skylake should make this difference even higher. Lower power usage, same OC ability or higher and we have a winner.

    Xen- AMD's next generation CPU.

    It is Zen, not Xen.

    I am not all that impressed, really. I see no real reason to upgrade from my 3570k. Taking a step backwards, on the IGP, makes 0 sense, also.

    I disagree completely in the iGPU part. You don't need every generation of mainstream CPUs to have performance improvements so massive in terms of iGPU. Intel still has a lot of work to do driver wise and pulling better and better hardware doesn't put them in a better position.

    Plus, a better iGPU means less actual CPU. If you ask me, I think this OC is possible because they held back on iGPU and process maturity helped a lot.

    Cheers!

    I know. I keep waiting for a reason to upgrade my 3930K setup and this is yet another gen I won't bother with. I thought they'd at least start giving us 6 cores standard with this gen. Not so.
  • Math Geek
    i like the pricing for the chips which is basically the same as current 5th gen i5/i7. too bad the new mobo and ddr4 ram will drive the total cost way skyward in the beginning. can't wait for those prices to drop and match current ddr3 and z97 mobo's. then we're talking a bit better.

    and why the hate on the igp? the AMD apu's have had a solid igp for a long time now yet all they get is hate since "no gamer uses an igp anyway" so now intel gets the igp hate as if folks will use it? so gamer will use the intel igp but not the amd one? come on folks can we at least be marginally consistent with the hate?? do gamers/enthusiasts care about igp or not?

    i'm more confused than a hungry baby in a strip club!!
  • royalcrown
    I do like the platform upgrades, specifically thunderbolt and new USB speeds. We just need more stuff that would use them. As far as the CPU, not so excited, like most of you.

    How many would upgrade if there was lots of thunderbolt and USB peripherals, and they weren't stupidly expensive ?
  • xenol
    I'm not bummed about the IGPU taken a step back because for the most part, most people who buy one of these aren't going to use it anyway. Unless Intel and others have finally implemented desktop switchable graphics.
  • wtfxxxgp
    I don't understand the negativity. It's brand new. Even the mobos and memory will be fresh and new. I honestly think that Intel still has a sucker-punch waiting to be revealed depending on what Zen is capable of. Why bring out your very best when mediocre is enough to beat your closest competitor, after all? It's far more lucrative to keep providing small incremental updates and charge a premium for every iteration than it is to say wham-bam and provide the masses with your very best effort and then have to charge a massive premium for it. I say be happy, every new bit of tech comes with advantages. I AM disappointed about the IGP though. These days I find myself playing MOBA games that don't require a lot of muscle - I'd love it if I could get a brilliant CPU and more than adequate IGP without having to shell out more money for a discrete GPU. I hope they do release something more top tier in both areas on the same CPU - I'll definitely purchase something like that.

    Something like when Thomas Edison said, "Never give them the best first." I think it was him anyhow.

    I agree from a business perspective, but from the perspective of actually advancing our computing paradigms and platforms, it is holding things back. The "speedbump" junk is a ball and chain on the ankle of advanced tech. It's screwing US a lot.

  • bystander
    What tests are you looking at, the IGP is faster than previous models, unless you look at the Iris and Iris Pro comparisons, which are specialty parts. Skylake will likely get an Iris and Iris Pro version as well.

    In which way is he saying that the CPU he has is better/superior? He simply doesn't. Having less features or speed doesn't mean nothing when the user is comfortable with the performance. I have a friend who still has i7 970 and is still satisfied by it.

    You guys easily get mad at such statements which are ambiguous. Stop faning too hard.

    The rationale most enthusiasts use is that the die area used by the IGP could have been used for more cores or more cache, or that the die area could have been reduced to lower cost.

    As for why they are more upset about AMD focusing on CPUs with IGPs, that would likely have to do with how AMD lags so far behind Intel on CPU performance under most scenarios. Since the gap between AMD and Intel CPU performance is so wide, people simply accept Intel's IGP as part of the price premium. For those who adamantly refuse to pay for an Intel IGP of any sort, even disabled as is the case with some LGA115x Xeons, but still want Intel's CPU performance, there are the LGA2011(-v3) options.
