Office Performance

The dynamics of CPU Turbo modes, both Intel and AMD, can cause concern in environments with variably-threaded workloads. There is also an added issue of the motherboard remaining consistent, depending on how the motherboard manufacturer wants to add in their own boosting technologies over the ones that Intel would prefer they used. In order to remain consistent, we implement an OS-level unique high-performance mode on all the CPUs we test, which should override any motherboard manufacturer performance mode.

All of our benchmark results can also be found in our benchmark engine, Bench.

Dolphin Benchmark: link

Many emulators are often bound by single-thread CPU performance, and general reports tended to suggest that Haswell provided a significant boost to emulator performance. This benchmark runs a Wii program that ray traces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single-core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53 minutes.

Dolphin Emulation Benchmark

All AMD CPUs performed similarly here.

WinRAR 5.0.1: link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2,867 files across 320 folders totaling 1.52GB – 95% of these files are small typical website files, and the rest (90% of the size) are small 30-second 720p videos.

WinRAR is all about threads and DRAM speed, so the CPUs that can support higher DRAM frequencies get a boost.

3D Particle Movement

3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian motion simulations and testing them for speed. High floating point performance, MHz and IPC win in the single-thread version, whereas the multithread version has to handle the threads, and loves more cores.

3D Particle Movement: Single Threaded

Again, all AMD CPUs seem to perform similarly in 3DPM for single-thread mode, indicating that something more fundamental about the design is a bottleneck.

FastStone Image Viewer 4.9

FastStone is the program I use to perform quick or bulk actions on images, such as resizing, adjusting for color and cropping. In our test, we take a series of 170 images in various sizes and formats, and convert them all into 640x480 .gif files, maintaining the aspect ratio. FastStone does not use multithreading for this test, and results are given in seconds.

Single-thread frequency and IPC win here.

Web Benchmarks

On the lower-end processors, general usability is a big factor of experience, especially as we move into the HTML5 era of Web browsing. For our Web benchmarks, we take four well-known tests with Chrome 35 as a consistent browser.

    Go go Rocket APU!

    Would be nice to see this compared to the latest Intel offering. Any plans on reviewing Skylake i3/Pentium? I doubt Intel sends out samples of those, but they've been publicly available for a month or so.

    Yep, HD530 is pretty beefy and coupled with ddr4 it would probobly be quite competitive with apus gpu.

    You did see the table comparing the A8-7670Ks iGPU with the i5-6600s HD 530, right? It's literally one paragraph up from the comments in the conclusion, if you missed it. To sum things up: the 7670K wins every test outright, with only a few specific 99th percentile numbers not being clear wins. Even with the Intel CPU running DDR4 (although at the same frequency as the DDR3 used).

    You said it yourself : Intel's iGPU was intentionally held back.
  • Valantar - Wednesday, November 18, 2015 - link

    Testing both chips at Jedec spec is holding one of them back? Othereise, shouldn't both be tested with OCd memory?
  • hojnikb - Thursday, November 19, 2015 - link

    Thats just one game though... I want to see a full benchmark comparing more games.
  • Ian Cutress - Wednesday, November 18, 2015 - link

    I'm trying to get a source for the whole stack for testing review. Keep fingers crossed. :)
  • nathanddrews - Wednesday, November 18, 2015 - link

    I expected the the Intel HD 530 graphics to perform much worse than the 7670K, despite the CPU processing advantage and extra $100 in price. 9-18% faster average frame rates, but very small gains on 99th percentile. The 530 can be found on CPUs all the way down the stack to the $60 Pentiums. I was expecting something closer to a 50% gap, but I'm probably envisioning 7870K vs Haswell IGP.

    Too bad there's no Carrizo desktop SKU.

    This really looks like it should not of even existed. Look at that lineup how close everything is together.
