No, it's the same 0x15 AMD family, as the AmdMsrTweaker readings of these 4 flagship Apus given below shows. I can't get SuperPi past the stage of scanning my hardware, so have no readings for you, but I gave my Cinebench R15 readings in Post 28 and jsc1973 gives a pertinant comment on that in the post above your own.




I've just completed my voltage table for this A10-7870K, showing the lowest voltage I could set in AI Suite III to achieve a 10 minute run in P95 without errors. A couple of increments above these readings should give a 24/7 stable OC for the given speed, 3500MHz-4700MHz (4800MHz needed to trip the yellow volt warning at 1.66875V(+29) in AI Suite III - it's 1.725V in UEFI BIOS).

Sorry I never did a voltage table for the A10-7850K, it got lost in all the excitement of not getting it into the 5GHz Club. The A10-7870K has been a much more humdrum affair.

Nice work! The 5GHz is a suicide shot?

Unlikely the voltage/frequency relation doesn't look very promising, you don't have the 7850K values for direct comparison, but they seems to be very similar, not like the gap between the 5800K and 6800K.

Yes, with safety in mind, that was a single core shot with the lowest voltage I could get away with - 1.61875V(+21) - and crashed when I got the confirmation screen back from canardpc. I could have gone up to 1.6625V(+28) and would probably have got a stable OC at about +24, but there doesn't seem to be any capacity for stable multiple core OCs above 4900MHz - especially when you deviate from 100MHz to get a clearance multiple.

Taking the default voltage from the highest non-turbo P-State, 1.4875V as Increment 00 on the A10-7870K is Increment +24 on the A10-7850K and Increment +28 on the A10-6800K and A10-5800K. (See the table below)

Because I was using Manual voltage adjustment mode and the default LLC settings all the voltage readings I got back during the stress testing were lower than the voltages I set and after the excersize I was able to reproduce the benchmark scores I got before I started it.

I'm sure that a more subtle approach to voltage adjustments, LLC settings and iGPU underclocking will yeild results above 4900MHz but in crude CPU OC terms the A10-7870K looks like an A10-7850K in spite of its very different P-State settings.

However, the divergence in P-State patterns is obviously affecting IPC rates, as shown by this comparison of wPrime and SuperPi results for my A10-7870K with those for the the other three flagships from an overclockers review from 2014, which gives the 7870K a win in SuperPi and a 2nd place in wPrime.
Code:
+-------------+-----------+-----------+-----------+-----------+
|Benchmark ^  | A10-5800K | A10-6800K | A10-7850K | A10-7870K |
+-------------+-----------+-----------+-----------+-----------+
|SuperPi 1M   |    22.801 |    22.012 |    18.907 |    17.938 |
|SuperPi 32M  | 22:32.062 | 21:34.318 | 17:09.633 | 16:12.907 |
|wPrime 32M   |    15.923 |    15.679 |    12.872 |    13.086 |
|wPrime 1024M |  9:19.907 |  8:07.919 |  6:46.194 |  6:51.356 |
+-------------+-----------+-----------+-----------+-----------+

Having rattled on about voltage increments I should remember that these are not easy to find, so I include the table below which may be of use as the basis for a printout or adjustment for other processors using Block Select Mode in a text editor.
Code:
0.8V to 1.9V by 0.00625V
A = Increments for A10-5800K and A10-6800K
B = Increments for A10-7850K
C = Increments for A10-7870K

Rep: 87 (Unique: 57)
I have reassessed my TIM application for the test setup since the method that worked for the Mugen 3 no longer does so for the Mugen 4, which definitiely prefers to splodge the rice grain of Arctic Silver 5 itself at the 10th turn of the screw.

Reworking the voltage table with the improved cooling led to a few adjustments in the results, as shown in the reworked table below, so I refer back to the original table in Post 41, for the differences.

While I was at it I decided to take the A10-7850K for a spin and construct a voltage table for it after 14 months of light use. The results show that the 7870K and the 7850K aren't nearly as similar - actually, 300MHz less similar - than my last post made out. In fact, taking into account the improvements in the integrated graphics, the 7870K should be seen as an important upgrade.

Incidentally, something which I have never seen mentioned in any review or processor specification, but which is definitely of importance, is the different voltage warnings which the motherboard and its software derive from each processor.

So from what i undestand is that you can exspect the 7870k be some 10/15% faster/stronger than the 7850k?

It means you can overclock the 7870K as securely at 4.6GHz as you could overclock the 7850K at 4.4GHz - the value of which can only be known by those who have spent the last 12 months struggling to get the 7850K past 4.5GHz. It means you have 866MHz default integrated graphics instead of 720MHz and a microcode upgrade that can produce the Luxmark result I cited in Post 24. That doesn't mean everything you do feels 10-15% faster but it does mean that when you push the system it will go further - and sometimes a lot further.

My 3Dmark score ( Cloud Gate ) when running Hybrid crossfire with a R7 250:

11726

http://www.3dmark.com/cg/1779895

More than pleased with the results for such a lowbudget CPU and dGPU.

7850K @ 4.9Ghz (Vcore - 1.55)
Memore @ 2400Mhz CL9
NB @ 2400Mhz (NB voltage - 1.50)

IGPU and dGPU overclocked to 1100Mhz on the core and 1200Mhz on memory.

These settings were also BF4 stable.

And yes, that was on a Phase Change system tongue.gif

To be honest, Kaveri is prob. one is the funniest thing I had the pleasure to play with in a long long time - Intel gone so incredible dull, and having to balance the CPU, dGPU and iGPU is great fun - Especially when everything works together and starts flexing thumb.gif

That is some very very nice settings :-)
Could you try and run firestrike and post the results please, would like to see the score and compare it to one i got with a 760k and a 750ti :-)

So is this Godavari or some middle of the road refresh? I'm not seeing any reasons not to just go for a 7850K now if its the former... I'd be overclocking a little but not massively so. Anyone got a good reason to go for this instead? Is the iGPU better?
