x264 HD Encoding

x264

Simply put, the x264 HD Benchmark is a reproducible measure of how fast your machine can encode a short HD-quality video clip into a high quality x264 video file. It’s nice because everyone running it will use the same video clip and software. The video encoder (x264.exe) reports a fairly accurate internal benchmark (in frames per second) for each pass of the video encode and it also uses multi-core processors very efficiently. All these factors make this an ideal benchmark to compare different processors and systems to each other. We are using x264 HD v5.0.1 for this test.

x264 HD Encoding Benchmark

This application scales across many threads and is ideal for processors with Intel Hyper-Threading or a bunch of cores.

x246-5775c

Benchmark Results: The x264 HD v5.0.1 benchmark showed the Intel Core i7-5775C was able to get 65.86 FPS on pass 1 and 16.41 FPS on pass 2. With the processor overclocked up to 4.3GHz we were able to get 75.93 FPS on pass 1 and 19.42 FPS on pass 2, which is slightly faster than a stock clocked Intel Core i7-4790K!

    I was expecting more from this. Integrated GFX performance is nice, but why would you buy a high end 1150 i5 or i7 and use integrated GFX. If the GFX are that important you would buy a discrete GPU, but if GFX aren’t important then you would buy a cheaper 4790K or 4770K, or more likely the non K parts and a H97 board. As for the cpu, seems 4790K is a better option at stock.

    On the plus side this may mean that AMD push out a console level APU to get back ahead of the game, it’s not like they can’t do it as they are already making the XB1 and PS4 APU’s. I doubt they will as they will likely drop the ball as they usually do, but it would be great for cheap gaming PC’s if they did and I bet they would sell like hot cakes, and god help them if the i3’s have this IGP boost. Anyway, I guess no upgrade this year for me then as my 4770K is sitting nice and stable at 4.7GHZ and these chips don’t seem to be worth the money even if it was overclocked to the same speed.

  • I love how in the gaming tests you guys just conveniently remove the i7 920 and the AMD APU’s so you can talk about broadwell keeping up with the “big boy” CPU’s.
    Because you don’t want to show that the APU’s and the 920 get virtually the same FPS as the extremely overpriced newer i7’s and that there is no reason to pay the premium?

    • Nathan Kirsch

      It’s because we dropped off the chips without integrated graphics support… There is no other ulterior motive there.

      • What?
        The APU’s all have integrated graphics and you guys are using dGPU’s to test anyway…
        Why don’t you put all the rest of the chips through the same gaming benchmarks to get a clear representation of where it sits.
        Instead of making it seem like its in a class of its own when literally the 920 is the only chip without integrated graphics.

        • Nathan Kirsch

          we have two pages of integrated graphics testing… We heard feedback from our readers that they wanted to see add-in discrete card performance as well, so we later added that. That is why not all the CPU’s were included. We just haven’t had the time to go back and re-test them all. All the testing doing with discrete GPUs have integrated graphics and we tested both iGPU and discrete on those particular chips.

        • Please test all the CPU’s with dGPUs to show subjective gains overall.

  • LionS7

    To be honest I like this CPU, but sadly I can’t afford it.

  • Mike

    It’s nice to see that Broadwell chip is a beast and it outperforms the Haswell 4790K for clock per clock performance and it’s cooler. Must buy!

  • FXi2

    x99 Broadwell cpu’s please 🙂
    @ Intel

    • Nathan Kirsch

      They are on the roadmap! Broadwell-E unless the cancellation rumors are true and they will skip it in favor of Skylake-E.

  • Nathaniel Graham

    The processor is almost as disappointing as the number of typos in this article. Thanks for the review though.

    • Nathan Kirsch

      Sorry for the typos! We run everything through the MS Word Spelling & Grammar check, but it doesn’t catch everything. Other than that we rely on peer editing and our readers is the last line of defense. Please e-mail me over the typos you see if you would like and I’ll get them fixed!

      • Persian Scientist.

        A computer that has been programmed by another man’s deceptive ability to spell check is entirely not accurate. Don’t rely on that damn thing.

  • Iluvatar Valinor

    Nice to see i7-920 in test results, has been working flawlessly ever since i got it, will upgrade to Skylake.

  • DougLord

    This would be amazing in a 5lb laptop.

  • anon

    I love to see the i7-920 in the tables! Given the performance can be considered linear up to about 4Ghz for this cpu, 4 (GHz) by its 2,66 base speed gives a 19,57*1,5=29,35 fps in handbrake.

    Ok a 2009 cpu mild oced, vs the top 2015 cpu (400Mhz less because its 3,3-3,6) gives and advantage in handbrake of 5 fps.

    Same situation with most cpu bench not involving encryption.

    Good job marketing department, because the RD department sucks.

    • Nathan Kirsch

      good points and it’s amazing how the super popular Core i7-920 is still hanging in there!

  • Geekosa

    Recommended Award.
    OMG ! Is it possible to recommend this CPU with this fucking crazy price ?

    • Nathan Kirsch

      For those looking for something with integrated graphics this is a damn good processor. In fact, I look forward to upgrading some of our Z77 systems with 3770K’s to Z97 systems with 5775C’s here for mainstream office use. Pricing isn’t too crazy… The tray pricing on the 4770K was $339 at launch. This processor is listed higher at $369, but that isn’t bad considering all the extra EU’s and eDRAM they built into the processor.

      • Geekosa

        In France the 4790K is 350 € and the 5775C is 420 €
        70 € is a huge difference ! The price of the 4790K never dropped, and the 5775C is less powerful, is launched one year later and is more expensive. How should we recommend it ?
        The 5775C should be at the same price than the 4790K.

        Do you realize ? This CPU is 90 € more expensive than the 4770K which is 2 years old, and isn’t more powerful.

        Recommend such a crap is like to agree to be whipped by a sado-masochist.

        • Nathan Kirsch

          Yeah, if there is an $80 difference you’d be better off going with a lesser priced Haswell processor and using that money for a discrete graphics card! Broadwell is recommended for those that don’t want a discrete graphics card. There is a reason it didn’t get a value award or the editor’s choice award. This card was recommended because it has the best integrated graphics performance for any CPU. That is a first for Intel and they deserve props on that.

        • anon

          I still dont get, anyway, who or recommended by who, would select an i7 top-of-the-line cpu because of its GPU capabilities. Even the poorest workstations wear a K600 GPU. This is all merchandise because they want to promote their GPU for the mobile / tablet market.

          All that die wasted in a gpu, really. Its the same core technology shrinked we had 5 years ago, and thus, more power efficient.

          Then you think, ok why i3 or i5 series, which is the target for the integrated GPU, dont have the top of the lane GPU chip on them. Basically because the lower tdp cpu would be a benefit for the gpu tdp. And you find they’ve got a crappy gpu as well.

        • Nathan Kirsch

          “All that die wasted in a gpu, really.” I guess maybe that is why all the initial batch of Intel Skylake processors will have just GT2 graphics?

        • Lindsay

          This is a 65W CPU. It should be compared to it to the equivalent 65W “S” Haswell SKUs.

        • Geekosa

          Nope.
          People buy unlocKed CPU for performance. They do not care about 20 W of consumption, but they care about 70 € for lower perf !

        • Billy Pistocco

          uggg..

      • xcore

        OC ignoring the the extra EU’s and eDRAM for the moment and take the time to realize that broadwell was a tick as in a shrink and yet we don’t see the usual 20% or greater generic speed bump with these….

        something tells me Intel have intentionally crippled 5775c broadwell to lower than 4770K default speeds just to help sell the real tock Skylake and its EU’s and reduced EU’s and eDRAM soon , and that’s a shame along with the lower eDRAM and missing AVX512 SIMD….

    • RedSun

      take a look and see what happend when i disabled the igpu and the cpu gets the 128 L4 memory cache. https://i.gyazo.com/851a38b3bff0b540dd808be5bb71cbcc.png

      greetings.

    CPU performance the same as Haswell.

    A10-7800 vs. i7-5775C graphics performance:

    28nm vs. 14nm
    DDR3 bandwidth starved vs. dedicated eDRAM
    TDP lowered vs. stock TDP

    And still the AMD manages to reach 70% of the performance? This just shows that Intel’s GPU arch is still light years behind compared to the likes of Nvidia or AMD. They really need to step up their game with Skylake if they want to have any chance against the upcoming 14nm FinFet HBM chips from AMD.

    • Carl

      For mass-buyers. you are right. For most enthusiast who will buy a discrete video card anyways, Intel is still the way to go.

      • Anonymous

        Yep, no questions asked, but the Haswell chip is better than this. And who knows what Zen will bring, maybe the race will be closer again. Intel isn’t pushing CPU performance at all, that gives AMD some time to catch up.

      • DougLord

        Intel is the way to go for everyone. When was the last time you saw someone selling a PC with AMD CPU?
