3DMark & Cinebench

Futuremark 3DMark 2.2.3509 – link

3DMark is a popular gaming performance benchmark that includes everything you need to benchmark your PC whether you’re gaming on a desktop PC, laptop, notebook, or a tablet. 3DMark includes seven benchmark tests and we’ll be running ‘Sky Diver’ that is aimed at gaming laptops and mid-range PCs.

Maxon Cinebench R15.038 – link 

CINEBENCH is a real-world cross platform test suite that evaluates your computer’s performance capabilities. CINEBENCH is based on MAXON’s award-winning animation software Cinema 4D, which is used extensively by studios and production houses worldwide for 3D content creation. MAXON software has been used in blockbuster movies such as Iron Man 3, Oblivion, Life of Pi or Prometheus and many more.

3DMark and Cinebench Benchmarks Results Summary: The Dell XPS 13 9360 with the Intel Core i7-7500U was between 10.4% faster than the Dell XPS 13 9350 with the Intel Core i7-6500U processor, which is impressive again. The Intel Core i7-7500U was also 8.4% faster in the OpenGL graphics test found in Cinenbench, so there are solid gains in GPU heavy tasks as well. When you look at the CPU performance gains in Cinebench you are looking at 7.6% gains with all available cores and then an earth shattering 17% performance increase in single threaded performance. The Intel Core i7-7500U has a 400MHz clock speed advantage over the Core i7-6500U, but that is only a 12.9% advantage when it is max boosting! Impressive scores that we really weren’t expecting.

    I have an option for an i7 6500u model for 940$ us. Worth it?

  • YOUDIEMOFO

    Not sure if I’m just seeing it wrong, but would these scores not be the same if core “clock speeds” were the same…!? I get that there is more performance to be had on the kaby, but this would not be enough for me to jump ship for such a small incremental performance increase.

    Great review. Thanks. Intel should have just waited on this one. Not enough to warrant an upgrade. They need to acquire Nvidia and get some real graphics pros on board. Yawn! It will hopefully lower the Surface Pro 4 pricing even more as rich boys upgrade to this “power” processor. lol.

    • AdamBoy64

      True, if you’re already using an i7-6500u there’s not much of a jump.

      It’s good for those in the market though to be able to compare. I was considering a 6500u as it didn’t seem much different, but it seems like there’s more of a jump than I expected.

  • Greg Zeng

    Running on battery makes the upgrade very worthwhile. These improvements should also be visible on other products with the new CPU.

    Great article. Its not very often we see such thorough information. Thanks for that. Helps clarify a bit more of the true benefits on Kaby Lake over Skylake.
    Nice work

    10% more performance for 10% higher clock speed? If scores are not normalized its difficult to compare when products are sooo similar.
    The performance boost could be alleged to a higher absolute performance, but its not.

    Also in the power comsumption chart, HEV (page 8) decoding power use seems missleading. You cannot use a line graph to compare different usages of power because the lines between the points mean a progression which is non existant. Should be a bar chart as well.

    I like very much legit, and I think you should pay attention to this kind of details.

      The claim is the 14nm+ process achieves a higher clock with equivalent TDP.

    • Nathan Kirsch

      I get your point on the chart, so I updated it! Thanks for the feedback and we always strive to make the reviews as good as possible!

      • anon

        This kind of feedback is what makes legit what it is. Kudos for you.

    Excellent article, Nathan. Nice to see one can have a long flight overseas, etc. and never run out of battery.
