Real World CPU Benchmarks
Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things – better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal), at the expense of heat and temperature, but also gives in essence an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, memory subtimings at JEDEC). Processor speed change is part of that risk which is clearly visible, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the purchase.
As far as we could determine, the ASUS A88X-Pro did implement a form of Multi-Core Turbo given some of the results in multithreaded workloads.
Rendering – Adobe After Effects CS6: link
Published by Adobe, After Effects is a digital motion graphics, visual effects and compositing software package used in the post-production process of filmmaking and television production. For our benchmark we downloaded a common scene in use on the AE forums for benchmarks and placed it under our own circumstances for a repeatable benchmark. We generate 152 frames of the scene and present the time to do so based purely on CPU calculations.
Compression – 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 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.
Image Manipulation – 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.
Video Conversion – Xilisoft Video Converter 7: link
The XVC test I normally do is updated to the full version of the software, and this time a different test as well. Here we take two different videos: a double UHD (3840x4320) clip of 10 minutes and a 640x266 DVD rip of a 2h20 film and convert both to iPod suitable formats. The reasoning here is simple – when frames are small enough to fit into memory, the algorithm has more chance to apply work between threads and process the video quicker. Results shown are in seconds and time taken to encode.
Video Conversion – Handbrake v0.9.9: link
Handbrake is a media conversion tool that was initially designed to help DVD ISOs and Video CDs into more common video formats. The principle today is still the same, primarily as an output for H.264 + AAC/MP3 audio within an MKV container. In our test we use the same videos as in the Xilisoft test, and results are given in frames per second.
Rendering – PovRay 3.7: link
The Persistence of Vision RayTracer, or PovRay, is a freeware package for as the name suggests, ray tracing. It is a pure renderer, rather than modeling software, but the latest beta version contains a handy benchmark for stressing all processing threads on a platform. We have been using this test in motherboard reviews to test memory stability at various CPU speeds to good effect – if it passes the test, the IMC in the CPU is stable for a given CPU speed. As a CPU test, it runs for approximately 2-3 minutes on high end platforms.

EXACTLY. I've been scratching my head on this one. The only possible argument would be that you can cram more gaming into a smaller case, but that's an idiotic argument because 1) who the hell is so desperate to fit a system down to the millimeter and 2) the real-life difference between mini-ITX and micro-ATX cases is often one or two inches in any given dimension.So ultimately Kaveri is, unfortunately, a bust. A moot point. A waste of precious R&D resources. And it's such a shame.
On the bright side, all they'd have to do is adjust the price point. A lot.

Obviously you haven't tried to build a computer in SG05 or Ncase M1. Not every ITX case is Prodigy or 250D. Most are much much much smaller in all dimensions than most mATX cases. I would say it's more of the ATX vs mATX that's always bothered me. More often than not an mATX case isn't much smaller than a well spaced full ATX mid tower.That said this motherboard is about as useless as one could be. I see why they are doing it. They want full sized full featured ATX boards for the AMD platform, but with AMD almost completely shutting down AM3+ developments, the future of AMD's platforms is in the FM2 and up. Spending 200$ on a full ATX system just to use integrated video doesn't make sense. I guess one could say there is more performance and power savings when tied to discrete AMD GPU. But APU's are at their best when they are the sole source of video. Certainly not worth spending i5 money otherwise. Which is why it would work best in an ITX setup where both space and cooling are enough of a issue that one would rather do without a discrete card if possible.

^^ ThisI was able to purchase the 7850K for 120 at local microcenter and a Asrock A88X-ITX+ for 100 at newegg. At $220 combined price, Kaveri is very hard to pass up. yes, you can get cheaper systems, but it's price/performance/size/power ratio is unique. This is no longer the case if you approach $300. They really need to drop the price down to around 100 for the CPU.

I'd have to agree with that.. Which is why I am waiting on the A8s Their supposed to be priced in and around 90-120 which is somewhat of a sweet spot. As we move up to the 150-180 dollar A10s that drops off a little as you could always pair a discrete card (say a GDR5 240 or something) and blow it all out of the water.BinaryTB - Tuesday, April 22, 2014 - link
HTPCs. Lower heat, lower noise, lower power consumption.CPU and graphics don't matter much if you can decode high bitrate video in hardware and put it all in a small package.
The same argument could be used for laptops as well.
But I do agree with you, if you have a desktop and want performance, separates is the way to go.

Power consumption and heat are the difference. I do agree with just4U that I really just wanted the A8-7600. With the price about a $100 it makes more sense to me. I think the OEMs cried for it so we got shafted in channel.abufrejoval - Tuesday, April 22, 2014 - link
I'm guessing as to what you'd want: A <95Watt TDP APU, which still has the biggest GPU AMD can make... I think you're willing to sacrifice CPU clock for low TDP, but not graphics performance and would like to hit the 65 or 45 Watt "sweet spots", right?Well you don't need to actually wait for anything: These APUs are all one single die anyway, including all the mobile variants (once they come).
And, at least on Asus, you have the ability to configure your desired TDP in the BIOS, at least between 40 (could be 45) and 65 Watts.
Here is what happens:
You leave that setting alone, you'll get a 95Watts part, which means 3.7 GHz base, while it will clock to 4.0GHz as long as the thermal budget lasts.
You set it to any number between 65 and 40/45 and you'll get exactly that: An APU which will fiddle with GPU and CPU budgets until they meet your TDP limit.
You use single threaded CPU load at 45Watts TDP, you may well get 4.0 GHz for quite a while.
You use tons of GPU, your CPU may well slow to the 1 GHz range (actually I believe it won't drop below 1.6GHz).
So with previous generation APUs like Trinity and Richmond the TDP settings were hard-wired into the die before packaging and sale. With Kaveri, from what I am seeing, there is really just two variants: One with 512 graphic cores enabled and one with 384 graphic cores enabled. Everything else is configuration done completely in software, which is just perfect from where I stand ;-)
I can buy a Kaveri today and push it to its absolute limits with heavy overclock on a "Pro" mainboard and I can transfer it into a mini-ITX board tomorrow and tell it to never use beyond 45Watts and it will just do as it was told!
Completely anti-market-segmentation and just the way I like it as a *consumer*.

I really regret going with ASRock FM2A88X Killer+, nothing but memory problems, basically no driver updates on driver page, ughhtuklap - Friday, April 25, 2014 - link
seems that you have to take it unto asrock.. I was targetting ASRock FM2A88X Killer+ too but when I read some problems and noticed that there are no driver updates i switched my eye to asrock fm2+ extreme6+ ^_^ never had problems.. although I wish they have esd protections and anti-surge ic's placed on the board. also they should have made it sturdier.all in all quite happy.
this board is solid. but the thing here is it lacks on board switches for power and reset

I'm sure this is a great boar but none of this matters until AMD release a CPU that is power consumption and performance competitive with what Intel is currently offering. The AMD on board graphics are great but the rest of the CPU and the power consumption are currently simply not competitive.
