Performance in Applications

To test the processors performance during data archiving we resort to WinRAR archiving utility. Using maximum compression rate we archive a folder with multiple files with 1.1 GB total size.

WinRAR is sensitive to the processor speed when working with the memory sub-system, and as we have seen, Socket FM2 platform does have issues here. Besides, Trinity doesn’t have L3 cache memory, therefore it is not surprising that A10-5800K falls behind all competitors except Llano.

The processor performance in cryptographic tasks is measured using a built-in benchmark of the popular TrueCrypt utility that uses AES-Twofish-Serpent “triple” encryption. I have to say that this utility not only loads any number of cores with work in a very efficient manner, but also supports special AES instructions.

Encryption is an example of a task where Core i3 processors reveal their weaknesses. Sufficient number of computational cores and AES instructions support are necessary to ensure that encryption algorithms will work fast. Core i3 with Ivy Bridge microarchitecture doesn’t have either of these. However, A10-5800K looks great here. And that is because AMD adds support for all new instructions sets to their new processors irrespective of their market positioning.

Now that the eighth version of the popular scientific Mathematica suite is available, we decided to bring it back as one of our regular benchmarks. We use MathematicaMark8 integrated into this suite to test the systems performance:

Wolfram Mathematica is traditionally one of those applications that work well on Intel processors. Therefore, we are not surprised to see that dual-core Core i3 are way ahead of the quad-core and six-core AMD processors with any microarchitectures. Here Trinity catches up with Socket AM3+ Bulldozer processors and is 6% faster than A8-3870K.

We measured the performance in Adobe Photoshop CS6 using our own benchmark made from Retouch Artists Photoshop Speed Test that has been creatively modified. It includes typical editing of four 24-megapixel images from a digital photo camera.

Trinity’s result in Photoshop is not that good. Although it outperforms Llano by 6%, it can’t compete against Intel CPUs. The reason is obvious: low performance of the Piledriver microarchitecture in floating-point calculations inherited from Bulldozer. As a result, A10-5800K is 27% behind Intel Core i3 -3220.

The performance in Adobe Premiere Pro CS6 is determined by the time it takes to render a Blu-ray project with a HDV 1080p25 video into H.264 format and apply different special effects to it.

We have finally got those applications where A10-5800K demonstrates similar speed as Core i3 CPUs.

In order to measure how fast our testing participants can transcode a video into H.264 format we used x264 HD Benchmark 5.0. It works with an original MPEG-2 video recorded in 1080p resolution with 20 Mbps bitrate. I have to say that the results of this test are of great practical value, because the x264 codec is also part of numerous popular transcoding utilities, such as HandBrake, MeGUI, VirtualDub, etc.

New AMD microarchitectures suit perfectly for video processing. And even though A10-5800K is not that much faster than A8-3870K, this advantage is more than enough to significantly outperform any Core i3 models.

Following our readers’ requests, we’ve added a new HD video benchmark to our tests. SVPmark3 shows the computer performance in the SmoothVideo Project application which makes videos smoother by adding new intermediary frames. The numbers in the diagram reflect the speed of processing Full HD videos without the graphics card’s help.

This is another confirmation of everything we have just said above. Trinity copes great with video processing. And by the way, there are a lot of utilities that can use graphics core resources via OpenCL. So, A10-5800K is an excellent choice for an inexpensive system, which will mostly be used for HD video content processing.

We will test computational performance and rendering speeds in Autodesk 3ds max 2011 using the special SPECapc for 3ds max 2011 benchmark:

The processors usually perform the same way in rendering tasks as they do during video transcoding. It means that A10-5800K outperforms Intel Core i3, although the advantage is not very convincing. However, when it comes to the computing performance score, Trinity has a problem: this APU loses to all other participants except Llano.

We use special Cinebench 11.5 benchmark to test final rendering speed in Maxon Cinema 4D suite.

Back in the days, the performance of Bulldozer processors in Cinebench was almost a joke. And it is really sad that the new Piledriver microarchitecture hasn’t really changed a thing. However, keeping in mind that A10-5800K costs just as little as the junior Core i3 CPUs, there is no reason to complain any more: the price totally justifies the performance.
