Power Consumption and Temperatures

AMD A10-6800K Richland Review  

Power Consumption at the Wall

Power consumption is something often overlooked when talking about custom systems, as performance is typically paramount. However, when we're talking about an all in one CPU/GPU solution to be used in media PCs as well as low-power gaming systems, power consumption means a lot.
If the system's going to be on for extended periods of time, such as a media PC used to transcode video files for future playback, having an efficient system can save you a lot in the long run.

It is clearly evident that Intel's i3 processor is more frugal at the mains, sipping less than 60% of the power used by the 6800K when being stressed by OCCT's Linpack AVX stress test. This is of course a worst case scenario as the CPU is unlikely to face such extreme stresses in every day use, but even when running Unigine: Valley's Extreme Preset, a benchmark not unlike many modern games in terms of stress levels, the Intel system uses 50% of the power of Richland's top dog. 

When playing back a HD MKV format video file with VLC, the AMD chips are still using 10w more power than the i3. 
It should also be noted that the Richland processor is consistently using more power than its Trinity predecessor - a product perhaps of the higher performing cores on the 6800K.


As well as overall power draw, the temperatures reached by these CPUs are important to note. Both stock coolers used for the testing were ran at a constant 12 volts from the power supply, and both were at a noise level which would be unacceptable for a living room area where HTPCs are often used. As such, the temperatures yielded by our testing should give an insight over whether fan control could be used to keep the noise down, or if an aftermarket solution would be required for a peaceful experience.

The AMD processors are far, far hotter than their Intel counterpart. Even with the heatsink's fan running at 12v the AMD CPUs were nearing 100°C when the CPU was put under heavy load, while the i3 was sitting at a respectable 54°C. During HD Video playback the temperatures became a lot more manageable, as the 6800K maxed out at 68°C. 

With these results it should be clear that if CPU intensive tasks are commonplace on your HTPC you would need to purchase an aftermarket cooling solution to keep both A10s in check, or else put up with the loud noise from the stock fan.

I wonder how much the 2133mhz memory would improve scores? Apu's are known for loving fast speeds so running at 2133mhz vs 1333mhz should improve scores quite a bit I would assume. Nevertheless still a great chip.

Good job on this review Josh! I was actually surprised. In the first page(not trying to be picky) I felt there were way to many commas. I ain't no English major but seems too many were used
Keep up the good workQuote

The Orange One
Good work with the review Josh!
That APU seems like a great little chip, for the money!Quote

I was expecting a bit of a bump when it came to GPU performance.

But I guess it makes more sense that this is just really a minor refresh, given that Kaveri is supposed to arrive towards the back half of the year.Quote

I don't really understand why you ran your 1600mhz hyper-x at 1333. You have deliberately nerfed performance of the GPU. If users look at other reviews where the correct memory frequency was used (2133) the performance gains of the gpu are noticeable over the 5800k and destroy the intel i-3.

Bottom line - this is not a fair "real world test" who uses 1600mhz ram at 1333 mhz... REALLY.
I mean who even buys 1333mhz ram these days - NOBODY.
My conclusion is that you are just a bunch of intel lackeys...
Rerun the test fairly please.Quote

We ran at 1333 as we do ALL stock runs. Even the haswell review stock tests are at 1333 because thats what systems auto set themselves too.

Josh did not have time to run faster mem tests, all results in this review we ran while he was here the other week. Adding in extra mem speeds would have required a: them all to match to be comparable and b: taken twice as long which was just not possible.

I can say in our testing 2133 was not achievable with the Richland APU on test today.Quote
