CPU Performance

I often make a big song and dance about real world benchmarks being the main focus of a reviewer. Synthetics often stress parts of the CPU and distort advantages that a CPU might have and thus not affect you or me in the same manner when using the machine normally. For 2014 I have updated my usual benchmarking set, to include more video encoding and an image converter that takes 2D images and performs algorithms to convert the data into a 3D model. Some 2013 benchmarks are still here, showing what can be done, and to bring parity to previous CPU reviews, some synthetics are also included.

Agisoft Photoscan v1.0 - link

Our new main benchmark to AnandTech is provided by Agisoft. Their Photoscan software creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.

Agisoft PS v1.0 Total Time

AMD suffers in overall time due to the lack of full-blooded cores and the reliance on single threaded performance in certain parts of the algorithm.

Agisoft PS v1.0 Mapping IGP

The second stage of the benchmark can be accelerated by the IGP of an APU, and as a result we can see the power of the high end APUs for this work can outshine any CPU we tested today. This is really the promise of HSA, it's just going to take a while to get there for most apps.

3D Particle Movement - link

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 wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.

3D Particle Movement: Single Threaded

3D Particle Movement: MultiThreaded

AMD is still suffering a lack of FP performance in our 3DPM benchmark.

WinRAR 5.01 - link

Our WinRAR test from 2013 is updated to the latest version of WinRAR at the start of 2014. We compress a set of 2867 files across 320 folders totaling 1.52 GB in size – 95% of these files are small typical website files, and the rest (90% of the size) are small 30 second 720p videos.

WinRAR 5.01

WinRAR loves IPC from the high end Intel chips, but even against the older i5-2500K there is still a deficit. The 45W Kaveri APU however is within fighting distance of its main rival.

FastStone Image Viewer 4.9 - link

Similarly to WinRAR, the FastStone test us updated for 2014 to the latest version. 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 thus single threaded performance is often the winner.

FastStone Image Viewer 4.9

FastStone wants single threaded performance, so Intel wins here again.

    I don't know if anyone will even see this now but...

    "The reality is quite clear by now: AMD isn't going to solve its CPU performance issues with anything from the Bulldozer family. What we need is a replacement architecture, one that I suspect we'll get after Excavator concludes the line in 2015."

    I don't know that this conclusion is very fair considering this statement if you compare it to a previous article linked below. The linked article recommends a (currently) $100 100W A8-5600K. The Kaveri equivalent is a $120 45W CPU of approximately the same performance.

    Doesn't the linked article's recommendations contradict your Kaveri conclusion at least for some cases? Kaveri's CPU performance probably is sufficient for many discrete GPU setups.

    Gaming performance is usually (but not always) GPU bottlenecked, not CPU bottlenecked.

    The reason why a trinity was getting recommended in a lot of gaming boxes was that in dollar limited scenarios, you'll often get better gaming performance mating a $120 quad core trinity with a $300 gpu, versus a $220 i5 with a $200 gpu.

    For even better results, mate an $80 Athlon II X4 750K if you're going discrete gpu, but I don't think the gpu-less trinity chip was available then.

    I wanted to compare Kaveri to some other cpus not in this review. Bench would be perfect for that, but the Kaveri cpus are not listed there. Why? Can they be be added?

    Well at least this shows that AMD is able to increase performance significantly given the appropriate die shrink. I'm a big Intel fan but a healthy company/market needs competition, and looks like AMD is able to offer that in at least some areas.

    I have an h60 cooler on my 7850k with 2400mhz ram OC'd to 4.4ghz and I love it... I think the corner for APU's will really turn when DDR4 boards come out. I also would like to see an 8core, 24 compute gpu as well but that's probably a die shrink or more away.

    An Xbox One/PS4-like APU is what I'm still looking for from AMD. To me, that seems like the point where an APU becomes truly compelling as opposed to CPU + discreet GPU.

    I still can't understand why anyone would be insane enough to pay the outrages high price for a AMD APU simply because it has a built in GPU that can play some games! When for the same price you can get a high end i5 CPU and mid range GPU for a few dollars more! Or for the exact same price you can get a AMD quad and a mid range GPU. Either choice would bloaw any AMD APU out of the water! Yes you can crossfire the APU, But you can also crossfire and SLI regular GPU's. Besides by the time you paid the money for a AMD APU and a GPU to crossfire with it you could have got a nice i3 or FX 6300 or even a last gen IVY i5 with a GPU like a R9 270 or a GTX 660. And either one of those would blow away a APU/Crossfire setup! What are you people thinking? I swear people today would not only buy the Brooklyn bridge once but more than once!
  • P39Airacobra - Thursday, January 1, 2015 - link

    Most logical thing to do is buy FX-6300 for $119 and a Motherboard for $60 and then buy a GTX 660 or a R9 270 and buy a 1600x900 resolution monitor and then you will be able to max out anything.
  • P39Airacobra - Thursday, January 1, 2015 - link

    Besides 60fps on Medium/High at only 1280x1024 is a laugh! A GT 740 and a R7 250 can do better than that!

    After living with the processor on a gigabyte main board for the past several months, I can honestly say its bested both the core i3 and i5 systems (some quad core) I have used in the past. What it might not score on benchmarks for all out throughput it makes up for in its multitasking capability. What normally crashes my i3 and makes my i5 struggle while multitasking (many things open and operating at the same time), doesn’t tend to effect the A10 APU. The core i3 i am using is the later 3220 chip which completely chokes with anything above average multitasking under W7pro, even though it has 12 gig of 1600 ram. The core i5 was better at multitasking than the core i3 but still not near as effective at multitasking as the AMD A10 7850. Where I cannot speak to the performance of the AMD A10 for gaming, for multitasking is very effective.
    For gaming I have used the FX series AMD processors, both Quad Core and 8 core.
