Benchmark Results: CPU Short Form

Here are our results from our CPU tests. A reminder of our systems:

System Overview
  µArch APU Base / Turbo MHz Memory Channel
HP Elitebook 745 G2 Kaveri A10 PRO-7350B (19W) 2100 / 3300 8 GB Dual
HP Elitebook 745 G3 Carrizo PRO A12-8800B (15W) 2100 / 3400 4 GB Single
Toshiba Satellite
Carrizo FX-8800P (15W) 2100 / 3400 8 GB Single
HP Pavilion
Carrizo A10-8700P (15W) 1800 / 3200 8 GB Single
Lenovo Y700 Carrizo FX-8800P (35W) 2100 / 3400 16 GB Single


Three Dimensional Particle Movement (3DPM)

3DPM is a self-penned benchmark, derived from my academic research years looking at particle movement parallelism. The coding for this tool was rough, but emulates the real world in being non-CompSci trained code for a scientific endeavor. The code is unoptimized, but the test uses OpenMP to move particles around a field using one of six 3D movement algorithms in turn, each of which is found in the academic literature. This test is performed in single thread and multithreaded workloads, and uses purely floating point numbers. The code was written in Visual Studio 2008 in Release mode with all optimizations (including fast math and –Ox) enabled. We take the average of six runs in each instance.

3D Particle Movement, Single Threaded

In the single threaded mode, the 35W part is able to boost to a higher frequency, giving it the lead. The interesting element here is the mix of 15W and 19W results, putting the Pavilion with the A10-8700P at the bottom. This comes through in the frequency charts, where the Kaveri was able to boost above 3000 MHz often:

For multithreaded:

3D Particle Movement, MultiThreaded

The processors line up more as expected, with the 8800P still taking the top spot with Carrizo’s architecture resources showing the ability to scale better.

WinRAR 5.01

WinRAR is a compression tool to reduce file size at the expense of CPU cycles. We use the version that has been a stable part of our benchmark database through 2015, and run the default settings on a 1.52GB directory containing over 2800 files representing a small website with around thirty half-minute videos. We take the average of several runs in this instance.

WinRAR 5.01

WinRAR is a benchmark which loves DRAM speed, hence why the dual channel Kaveri system wins despite the increased horse power and thermal benefits of the Lenovo Y700. Unfortunately, the single channel design methodology permeates through the OEMs because of the factor of price and upgradability – if a machine is sold with only one module, it can be upgraded later. The other element is that the Y700 design also caters for Carrizo-L as pin compatible, so despite having two modules in there the system will always be limited to single channel. This is, perhaps, a grave error with any situation that is memory limited.

POV-Ray 3.7 beta

POV-Ray is a common ray-tracing tool used to generate realistic looking scenes. We've used POV-Ray in its various guises over the years as a good benchmark for performance, as well as a tool on the march to ray-tracing limited immersive environments. We use the built-in multithreaded benchmark.

PovRay 3.7 beta

For whatever reason, our script failed to record the score when it came to the Kaveri system and we only realized after the systems were returned. Nonetheless, the capabilities of the other systems shine through, showing that the A10-8700P can seem to have a big frequency discrepancy against the FX-8800P models. In actual fact this can be attributed to the temperature limitations on the Pavilion:


The full threaded nature of POV-Ray means that we’re on the limits of the A10 APU already, but when the system hits 55C or so, it clocks back to 2100 MHz to save a few extra degrees.

If we compare that to the Toshiba:


The Toshiba system also hits a temperature limit, but the barrier is way up at 70C, causing the system to knock back to 64C. The CPU frequency difference between the two does not look that different despite the +25% score in favor of the Toshiba, making it slightly deceptive.


HandBrake is a freeware video conversion tool. We use the tool in to process two different videos - first a 'low quality' two hour video at 640x388 resolution to x264, then a 'high quality' ten minute video at 4320x3840. The low quality video scales at lower performance hardware, whereas the buffers required for high-quality can stretch even the biggest processors. At current, this is a CPU only test.

Unfortunately HandBrake also had issues on a couple of systems – the Lenovo and the Toshiba. All the HP systems gave results, where the HP Pavilion came out on top:

HandBrake Low Resolution h264 Transcode

HandBrake High Resolution h264 Transcode

If we compare CPU use, the HP Pavilion is much better at using all of its threads than the Elitebook 745 G3:



7-Zip is a freeware compression/decompression tool that is widely deployed across the world. We run the included benchmark tool using a 50MB library and take the average of a set of fixed-time results.

7-Zip MIPS

Despite being a purely in-memory benchmark, the G2 shows some inefficiency compared to the Carrizo systems. The slight discrepancy between the 8800 and 8700 shows again, and the Y700 can stretch its legs. Interestingly, the Y700 was able to keep its full CPU frequency on all the time:


Despite the temperature of the CPU moving between 55C and 65C, the system never once reduced its frequency.

    Holy shit, I haven't seen that many pages in a long time. You don't see this much content very often. Gotta love dat chorizo. Reply

    ImSpartanus, they're just writing a comprehensive article. I'm sure they put in good work with all of them. Reply

    I think this article provides a pretty delicate and nuanced treatment of chorizo and its place in the market (both potential & actual). There's no doubt that the circumstances demanded it. This was not business as usual and I'm glad Anandtech recognized the need for that additional effort.

    We're fooling ourselves if we pretend that any journalistic entity puts the sane amount of effort into every project. We're talking about living, breathing humans, not robots.

    I found the language convoluted, verbose, and difficult to read, compared to, say, Anand's straightforward and logical writing:

    "Nonetheless, Intel’s product line is a sequence of parts that intersect each other, with low end models equipped with dual core Pentiums and Celerons, stretching into some i3 and i5 territory while still south of $1000. In this mix is Core M, Intel’s 4.5W premium dual core parts found in devices north of $600."

    "south of/north of"... can't you just put in "below/above"? And all that "intersecting of parts", can't you just say from the Atom to Pentiums, Celerons, i3's, and i5's....

    The whole thing reads like they're paying you to score a high word count. Lots of information to extract here, but it can be 3 pages shorter and take half as long to read.

    That is why Anandtech has video adds on their main page - designed for people like you. Who simply lack reading comprehension past 8th grade and find it hard to understand. Just watch watch the video on how to loose weight that auto-plays on the side.

    Or... try Tom's Hardware - they cater to your demographic.

    There's no question that Anand had a powerful way of writing that was uniquely simple yet educated you nevertheless. And for a layman that reads this sort of stuff to learn new information, that's very attractive and I kinda miss it (along with Klug).

    However, I give Ian a pass because he at least attempted to use other brand of conveying his ideas. In certain sections he used special table-like fitting to separate "parallel" sections/stances so that the rader would be more apt to compare them. So there's at least some effort, though he surely could do better.

    fmcjw does have a point, but in all fairness it is much harder to explain techical stuff in layman terms than it is to be long-wordy. Carl Sagan was the master of it on TV, and Anand was excellent at it on paper. Reply
  • JMC2000 - Sunday, February 7, 2016 - link

    I didn't find anything wrong with the language Ian used, as this is piece is still on a technical level, but can be understood by the layman that knows a bit more than just what the stickers on the outside tell.

    To me, the phrase "parts that intersect each other" lays out that there is a myriad of options where configurations overlap, where as saying "from the Atom to Pentiums, Celerons, i3s and i5s" indicates that there is a pricing structure that is related to general CPU performance, which there really isn't when it comes to low-end machines.

    "south of/north of" sounds better than "greater than/less than," which is more correct than "below/above" Reply
  • Sushisamurai - Thursday, February 11, 2016 - link

    yeah, colorful language is nice. Dumbing down adjectives or descriptions can often construe the true message IMO. This way, it paints a more descriptive/colorful picture.

    Keep up the good work Ian.
