Richland - the best OC APU - infos, experience, issues

[FlanK3r]

my review of Richland

[VulgarHandle]

In your review, you describe the 3 current chipsets. You listed all the differences except that A85X is able to do RAID 5.
It is also important to note that many, including myself, believe A85X based motherboards are likely to be the only socket F2 motherboards compatible with Kaveri.

edit: There is a graphic showing RAID 5 support.

[FlanK3r]

you right, I forgot at this information

[VulgarHandle]

Actually, one of your graphics shows Raid 5 support, my bad.

[AlleyViper]

Thanks for your review! Despite time consuming, it would also be nice to see a 965BE thrown in the mix (as they can still be purchased, even if not an APU).

Awesome review flank3r!!

Although the chipset may be compatible with Kaveri, the socket won't. So you'll have to change motherboard for Kaveri. Most probably A75/55 can be made compatible with Kaveri too, but that will be a business decision.

I don't see the point of having vishra getting 0 on those gaming graphs, but nice otherwise

beause it was with iGPU and I cant bench Visheras with iGPU

[The Stilt]

Don't make any quick conclusions

On AMD FX (Asetek 570LC) closed loop watercooler.
Around 27 celsius ambient.

Right, but it doesn't have an iGPU. Some i3s/i5s/ and/or i7s would have been more useful.

@Flank3r, great review dude, well done!

Probably this is the first LN2 result around, that's what my review sample can do:

Rig pic:


Real vcore = 2.1V ~ 2.15V

No 3D results because old LN2 bios (1.02Y) for FM2A85X Extreme6 kills 3d performance on Richland, don't know why but for example, the 3dmark06 result is +/- 2000 marks worse than it should be with this bios...

Anyway, Richland is great! Tons of fun benching this thing...

The A10-68ooK is currently being sold here in Australia.

While everyone was getting a hard-on for the Haswell's I in fact will be acquiring the A10. Already using the A10-5800K so this would be easy to swap over.

Nice to see AMD is still into updating their cpu's. I just wish the FX line would get a similar treatment as well.

[paulbagz]

Yeah doc, I am planning on building a nice 6800k box but have to get my Haswell build up and running (after I finish the girlfriends machine!).

your LN2 result is awesome! How good this one was at air/watter? There is mine at AIR:

And Stilts CPU looks very good too

Infiltration into the "River" territory successful



http://valid.canardpc.com/show_oc.php?id=2824536

VapoLS cooled.

The voltage scalability is still there, however it is unsafe to raise the voltage any further.
At these temperatures the leakage is still well present and the resistance is not high enough to prevent the strike-throughs.

Can't wait to see a 8GHz+ from this little beast.

[FlanK3r]

wow, there are nice results, seems I have chance atatcking 7.9 GHz with Richland too

[Darakian]

Wow. What sort of power draw are you guys seeing with these 5GHz+ OCs?

[FlanK3r]

Richland is not power hungry after OC (CPU part), maybe only +40-50W

[Daveburt714]

WOW! The masters are showing some KILLER clocks with this (mini) refresh...

I went to MicroCenter today and picked up a 6600K and ASRock EX6 for <$200. I was going to go for the 6800K but it'll eventually end up in my server/bedroom HTPC and video performance isn't all that important, as long as it'll play 1080p video it's enough, and cpu performance/power consumption was my concern.

I'm not going to say too much because I've only had a couple hours to play with it.
I will say, I'm impressed so far though! After just a little tweaking the chip does 4.9Ghz (air cooled) and power consumption was <250w while running Prime Blend...

I bought an ASRock EX9 (AM3+ board) a while back and wasn't all that impressed with it...
I'm happy to say the EX6 (FM2) version is much more user/OC friendly!

This combo was a good choice IMO. The only bad thing is now I want to play with it a little more before I replace the PHII 550 rig it was meant to replace.

You guys, have you seen Gigabyte's latest FM2 board which is coming down the line;

http://www.techpowerup.com/184887/gi...therboard.html

Now this is a motherboard for Richland. As soon as it shows itself here in Australia I'm buying it.

I would rather get a F2A85X-UP4 if I would get a Gigabyte in the first place.
G1 Sniper A85X seems to be inferior to UP4 in terms of the components.
Just 4+2 phase VRM and no PowIRStage fets either. And no external Pll.

Actually, in relation it consumes even more power than a Gen. 2 Orochi (Vishera).
The power consumption (again, in relation) is similar to Gen. 1 Orochi (Zambezi). The upper end (high CLK/VDD) power consumption is still better because the total amount of emitted power is lower (less heat, less leakage) plus the improvements which come from Gen. 2 (Piledriver) update. The iGPU will increase the heat load heavily, yet still not as much as a second compute unit pair would (2 vs 4 CUs).

I made some measurements on Richland a month or two ago, on a low(er) leakage part:

fSW (Core COF): 4700MHz
Pmax DCR: 113.5W
Imax DCR: 78.5A
VDD DCR (Avg): 1.474V

This was measured during CPU stress only (HotDog), so it is really the maximum possible value for the CPU.
Nothing to do with the values achieveable with real world applications:

DCR Peak Power by application (during 10 minutes):

100% - Hotdog 15h V0.02
87% - Linpack 11.0.1.005
87% - OCCT 4.40 (CPU OCCT - SDS)
87% - Prime95 V27.9 (LargeFFT)
83.8% - AOD 4.2.6 (Calculation Test)
83.8% - Prime95 V27.9 (SmallFFT)
72.9% - Blender 2.66a (Burning Plane scene)
70.6% - Cinebench R11.5
68.4% - X264 R2273
67.3% - Euler3D Stars (CFD Benchmark)
66.2% - HyperPI 0.99b
65% - AOD 4.2.6 (CPU Test)
62.9% - AOD 4.2.6 (FPU Test)
56.2% - wPrime 2.09

On top of that, the GPU adds:

At default clocks and voltage, a full configuration GPU (6 SIMDs, 6 TUs, 4 QPs, 2 RBs), HD 8670D consumes up to 42.5W (Furmark).
In real world applications the maximum is around 37W.

Still Richland scales very nicely at lower frequencies.
Even with a low leakage part I was able to reach 2.0GHz frequency at 0.829V Core VDD.
The power consumption was just 12.2W under Hotdog 15h, which is pretty damn excellent for a quad core CPUs.
