Real World Benchmarks

Dolphin 5.0 x64 Emulator Benchmark: link

The long awaited Dolphin 5.0 release happened in 2016 and thanks to a major cleaning up of the codebase Dolphin has reached a new level of efficiency, powered by a revitalized dynamic recompiler. Dolphin is considered by many to be the best Nintendo Wii emulator for PC you can find. It also works for Gamecube. We are running the official Dolphin 5.0 benchmark as it offers closer mapping to real world Dolphin performance as the previous version was extremely floating point heavy. We feel this is a pretty good general CPU benchmark for real world performance as emulation workloads are something that most gamers will run at one point or another.  We benchmark the standard Wii homebrew application and run it with the speed limit set to ‘unlimited’ and the External Frame Buffer set to ‘real’ in case you wanted to run this on your personal system.

Agisoft Photoscan 1.2.6 x64 – 2D to 3D Image Manipulation Benchmark: link

Agisoft PhotoScan is a stand-alone software product that performs photogrammetric processing of 2D digital images and generates 3D spatial data to be used in GIS applications, cultural heritage documentation, and visual effects production as well as for indirect measurements of objects of various scales. We us the 50 images from the ‘Building‘ sample data download page for our benchmark. We take the total time it takes to complete four steps: Align Photos, Build Dense Cloud, Build Model, Build Texture with all the default settings for each.

KeyShot 6.3 – 3D Rendering and Animation: link

KeyShot 3D rendering and animation software is one of the fastest, easiest way to create amazing, photographic visuals of your 3D data. We installed KeyShot 6.3 to do some benchmarking and real-world stress testing using the camera_benchmark.bip scene that is included with the application. This benchmark tests a 800×554 pixel image with a continuous sample rate and shows the Frames Per Second (FPS) that the scene is being rendered from. This scene has nearly 42,000 triangles and does a good job at using all available cores to render the scene.

Blender 2.78a Open Source 3D Creation Benchmark: link

Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation. We use the BMW CPU Benchmark (CCO, 3MB) created by Mike Pan for our testing.

Real World Benchmark Results Summary: When it comes to our ‘real world’ benchmark tests we found the Intel Core i7-6900K does really well in applications that use more than 4-cores as you can see in most of the charts. Our Dolphin emulation benchmark doesn’t use more than 4-cores, so you can see how clock speed and CPU architecture plays more of a roll in that benchmark. Single threaded and lightly threaded applications will run faster on the Kaby Lake desktop processors as they have nearly a 1GHz clock speed advantage on the 2 or 4-cores that they offer.

    What a Crock in ALL the forums they say the 6-8 Cores are Worthless Over Kill. Unless you spend ALL day editing and want to save time then it Becomes a TAX Wright off as a Business Expense. Other wise they have NO Use. My 2500 stock Blows through All games steam and Origin Max Out. I bought a Devil Canyon for 190$ that is even Over KILL. All these Stories are Just Advertisement to SELL something you Don’t need. And if AMD is really that Good Intel WILL have to drop their Prices in HALF.

      well it’s overkill until our software becomes so complex that we need the overkill as standard.

  • bennyg

    You’d have to be a complete idiot to buy a broadwell-E right now and not wait until Ryzen proves it’s better and/or Intel drops prices to compete

    My 3970X is holding strong. Love how my memory was supposed to be max 55gb/s and is actually running more like 62-65gb/s reads and writes. 64gb of quad channel ddr3 2400mhz is holding up just fine.

    “Both processors have 40 PCI Express lanes, so you don’t have to worry about the limitations of the Intel Core i7-6800 on Intel X99 platforms.”

    I don’t think the 28 PCI Express lanes on the Intel Core i7-6800K is a serious limitation. In SLI or crossfire, 8 PCI express lanes are enough to drive a second GPU without a bottleneck. Or you can just forget about SLI or Crossfire – a single GTX 1080 get’s the job done – even at 4K. You may have to dial back settings in the latest games – which I’ve done and the games still look great. Only in the most heavy threaded applications will you benefit from having 8 cores over 6. Those applications always make you wait…you’ll still be waiting…only waiting less. If your workload is only sometimes heavy threaded (Arguably 99+% of people on the planet) then you can save yourself another $600.

    When you compare the extra money spent versus the performance gained, the i7-6800K really shines.

      Agreed.

      And the 6800K isn’t even in the comparison charts.
      Funny how that works …

      Fake News

      • tristan smith

        “Fake News” really? is it not good to have nonsense out there that way we have to learn how to discern real from fake? correct me if i am wrong.

          ‘Triggered’ !

  • Dorian Kunch

    Nate, thanks for the thorough review and including my 2700K at 4.5 in da mix. I can still sit tight.
