[RT] AMD A10-7860K Review: AMD's Most Power Efficient APU

Back in February AMD announced the A10-7860K APU that aims to replace the A10-7850K. The A10-7860K is an interesting processor because it has a low 65W TDP, full A10 four steamroller cores and 8 GCN Cores with 512 stream processors and the 65W TDP makes it the most power efficient AMD desktop APU released. The base frequency of the A10-7860K is 3.6Ghz and boosts up to 4.0Ghz and its got an integrated Radeon R7 GPU clocked at 757Mhz. The A10-7860K comes bundled with the new Near-Silent Thermal Solution that's designed to handle TDPs of up to 95 watts. The K suffix means the processor is unlocked on both the CPU and graphics so you can squeeze a bit more performance if you decide to overclock it.

Not gonna lie, this is a pretty good chip for its price and performance.

All apus run at P3(3.0GHz) when running with the integrated graphics unit anyway, so it is useless selecting the higher binned parts(the point being that you would need to manually adjust the overclock via PS State Check to equalize P3 speeds with P0). Together with the memory bottleneck, it leaves little to the imagination in order to go for the 512 core variants rather than 384 core ones. A10 7700K & A8 7600K is all that you will ever need considering the downright nonsensical 2x8GB memory upgrade just to unlock the extra "dual-rank memory" bandwidth.
The better cooling solution, albeit, is a good incentive however the stock ones are very quiet <3000 rpm as well which you can manually control via motherboard AI Suite Control Center. Truth be told, disabling AI Tweaker(OC Genie/OC Guru) is the single most useful bios option in order to establish a cpu that behaves according to the expectation.
The stock bios settings are downright horrific, you have to return everything to 'manual' in order to revert them to their initial states. Sifting through the bios just to turn off 0.5% fsb overclock by turning "Automatic Overclock" setting from its native "Auto" to "Manual" is not worth the trouble.

These guys always have lackluster reviews for me. Overly simplistic and they didn't even bother to talk much about price or overclocking.

Thats a massive efficiency boost, Where did it come from?

Process maturation, transistor compression and power saving technologies. Carrizo is a much better rehash of the architecture that we've all seen since bulldozer.

CPU wise it is very much behind the i3.
Graphics wise, they only tested at 720p, in which case, it barely touches the workable smooth FPS.
For a super cheap machine? It is nice. For gaming without a dGPU? Can't see that doing very well without feeling underwhelming. Especially since I rarely see people buy today a 720p monitor.

Even if it is the most powerful (which it isn't seems the 7890K is better), it still feels not an amazing step forward.

I want to see them actually tackle an old i5 with a good iGPU core. But it will only happen when the zen comes out, somewhere in 2017.

You can build a fairly cheap system with an AMD APU that can play games such as CS GO, LoL, DOTA 2 etc without breaking bank. You can't do that with an Intel system unless you buy the 5775C APU but that thing costs like $350+ alone.

Get an i3. You won't be CPU bottlenecked as much if you drop in a GPU later.
