Stock voltages and tweaked voltages posted by The Stilt for a 7870K.


http://www.overclock.net/t/1555615/amd-kaveri-refresh-a10-7870k-apu-arrives/60#post_23963448

The 1.1960V value at 4.1GHz is remarkable as it s at 10% higher frequency than Hardware early retail sample that was capable of 3.7 at the same voltage, this chip has 20% better efficency at the same frequency within the same stability margin.

Oh SHOOT. Some people might be able to find a golden chip that pushes to 5 Ghz once the 870K is out. (Just not worth it with the 7870K imo xD)

My 860K currently sits @ 1.2 for 4.1 Ghz but beyond 4.5 Ghz it gets a little too hungry (I can reach 4.7...but I do not feel good about the voltage).

If the 870K ends up being just 10% better on the voltage for OCing...then 5Ghz is realistic.


And before anyone asks...I want 5Ghz...for...erhm...well..for reasons! (Mainly because it actually beats FX clock for clock...so if it can reach 5 Ghz that would be pretty neat)

The short answer is: no.

The long answer is: whatever chip they put into the ~$100-105 price point labeled "Kaveri refresh" or whatever is not really going to be much different than the original 7600. There are currently only three "new" parts, and those are the 7870k, the 7670k, and an OEM processor (8850B or something). Those are chips with the newer stepping (GV-A1).

Right now the chip sitting in the 7600's old seat is the 7650k, price-wise. Same stepping, same basic chip, but it's unlocked. AMD hasn't bothered to push the new stepping out to all their Kaveri SKUs yet, possibly due to old stock clogging up the channel. As time goes on, we'll probably see GV-A1 make it into other SKUs . . . but it could take awhile.

Keep your eye on the $100-$105 price point, or lower if you just want to buy an A8-7600 and be done with it.

Do you know the A8-7600 Godavari replacement?

The A8-7670K.

Anyone know when the 870k is hitting the market?

Q3 2015..



Temps under Prime 95, although it s with a better cooler than usual but still, the fan can spin as much as it wants it wouldnt be that efficient if the die is not in tight thermal contact with the casing..

I do not think of the 7670k as being the successor to the 7600. It's a replacement for the 7700k.

Right now, there are no locked GV-A1 parts with 384 shaders tuned for efficiency above performance, which was the MO of the 7600. Given the very tight price range for all Kaveri/Kaveri refresh parts now (basically $85-$140 for iGPU-equipped models), I don't know that we're going to see a replacement for the A8-7600. It's more likely that AMD will start selling GV-A1 stepping 7600s eventually, which would be pretty nice for people obsessed with undervolting.

A8-7670K, A6-7470K and Athlon 870K are the only expected Godavari releases for the retail market apparently, with locked parts for corporate PCs.

And the 7870k. Don't forget that one. Wouldn't they move all their production to GV-A1 stepping, though? Or is there some incentive for them to continue producing KA-V1?

My impression was that we'll see KA-V1 out of most Kaveri chips just due to existing inventories being um . . . robust. Yeah, that's it. Robust.

I'm not in a hurry. I'm looking to build a living room xbox alternative so I'm still undecided between i3+GTX 750 or cheap APU to play on TV screen.

A8-7600 is interesting because it loses just a few frames compared to the A10-xxxxk at stock clocks, is significantly cheaper and I don't think I'd overclock.

I wanted to wait anyway for Skylake Iris Pro parts to see the comparison.

I have no idea how many different Skylake Iris Pro parts will be available in desktop/sff form factors. If all they offer is an update of the i7-5775C, then you should expect it to be rather expensive ($360+) and far more powerful than what you'd "need" for a console replacement PC. Not that that's a bad thing.

If they sell socketed LGA-1151 i3s with GT4e iGPUs then you may find something a bit less expensive that should still be very powerful.

If you are looking to buy anything between now and then, the smartest play is to just look at your budget and buy accordingly. If you liked the A8-7600, it's still there, just cheaper than ever. The A6-7470k is an odd critter (1M/2T, apparently uses the newer GV-A1 stepping, 3.7 GHz base clock, unlocked) that may or may not meet your needs. Personally I'd rather have a lower-clocked quad like the 7600 for a console-replacement SFF box than a higher-clocked dual-core of the same uarch and the same TDP (7470k is listed as 65W). I have no idea how many GCN cores are in the 7470k, but it's probably 6C/384 shaders.

Then there's the 7650k which costs about the same as the 7600 did 6 months ago, but has a higher base clock. Not that it would provide you with much benefit, and let's be honest, darn near every 7600 out there can be set to its max turbo (3.8 ghz) no muss no fuss for a "zero volt" overclock.

If I were in your shoes and I just wanted something now, I'd get the 7600, set it to 3.8 ghz without touching voltage (actually, I'd probably have to lower voltage to ~1.2-1.25v) or anything else, and go with that. If you really want a step up in performance of any kind on FM2+, you'll have to go out and get something with more GCN cores (8C/512 shaders).

There is also an iris pro l5 Broadwell for something like 260.00 I believe. Don't know about availability of either that or the l7 though. But kaveri is still a lot cheaper.

The delay between $/€ evolution and retail price adjustment went shorter this year, this point to inventories being low, currently only retailers who have huge ordering capacity, mainly german retailers, still have acceptable prices...


As for Godavari it s a good choice if relatively high frequencies are targeted, i mean anything above 3.5 , below there s few difference, eventualy 4-5% in respect of TDP at 3.0.

Chips like the 7650K are the sweet spot even before the 7600 , dont pay attention to the 95W moniker, it s here only for economical reason as it allow to use existing cooling infrastructures.

Planet3D has made tests accurate enough to isolate its stock TDP at 46W at most, and at a modest 28.5% stock voltage margin, that allow undervolting down to 38.5W power comsumption and still retain 17.5% margin....

True. A Skylake GT4e successor to the i5-5675C would be cheaper than an i7 and would be "just as good" for the aforementioned use case. I still think an i3 would be even better, if such a thing ever comes to pass.

It would be nice to see voltage/frequency scaling for GV-A1 vs KA-V1 at frequencies below 3.5 GHz. I'm betting that GV-A1 would do better there, too.

I think the 7650k is overkill for what the OP wants to do, though. He doesn't seen keen on overclocking, so it would offer very little advantage to him over the 7600.

The 7650K tested by Planet3D did 1.050V at its stock 3.3GHz frequency while the 7870K tested by The Stilt was capable of 0.963v at 3Ghz and 1.064V at 3.5GHz , as said the difference at low frequencies is somewhat negligible, what they improved with Godavari is the high frequency behaviour.

Surely but it s more versatile if ever a little boost is needed in a few years, the price difference here is 10-15€, and the fact that it is ranked as 95W get you a cooler sized in consequence in boxed offerings...

Just wondering.. How would it look 720p gaming on a fhd tv? A8-7600 (or the k one) would struggle on 1080p but should be ok at 720p.

The elephant in the room is the i3+gtx 750 at just €100 more with far better performance though.

Or even cheaper, an athlon X4 860k plus GTX 750. I think that gpu with either cpu would allow you to play most games at 1080P. It is slightly faster than my HD7770 and the only game I cant play at 1080 at 30+ fps is Witcher 3.

A few more dollars for a 750 TI and you can. xD

To answer the other guys question:
But for 720P gaming a 7600 should be way fine. I mean I'd go for the 7650K for overclocking and so on(and since it generally feels like the better chip)...but generally...on 720P games like Bioshock Infinite or Alien Isolation will run on Ultra settings and stay above 30fps no questions asked while games like Shadow of Morder would be running on medium low in 720P.

Also i3 + GTX 750 would end up a worse combo than 860k + 750 Ti. 860K can pretty much be equal to the cheapest i3 if you overclock it a tiny bit(in multithreaded games, look at witcher 3 benchmarks, the 860K does really well there and the CPU side will easily carry you all the way up to 60FPS if you got the GPU to back it up)...and the price difference can be put into the Ti version of the 750...making your PC all around better. Yes, the i3 will stand out in games that only utilize 2 cores properly...but most of those games are old and will run on both chips regardless...but the difference between 750 ti and 750 is rather significant.

Of course the i3s' platform has a real upgrade path...but if you don't plan on spending much money on it, anyway...no use thinking about that path.

In over 15 years i never upgraded any cpu, always switched mb+cpu, so it really doesn't matter the upgrade path.

But in the end won't the i3 (say a 4150) be better in MT compared to X4 two modules?

I'd like to have 50 fps (to match TV refresh rate). Still wondering about the difference between 720p and 1080p on TV screen.. I will test a bit with my notebook


Edit: test done. 1080p is far better even on lower details. I guess that rules out Kaveri

If you're thinking of using the iGPU, then yeah, you may not enjoy a Kaveri much at 1080p. It would do okay with a dGPU depending on the title and some overclocking (thinking 860k).

It makes no sense to buy kaveri if you are going to add a dgpu. You would be better off to buy an Athlon X4, cheap FX, or i3.
