Kaveri 7850K nr1 -OC AIR (average chip)

[flanker]

So gonna for some OC test...and few interestings. This is not full version of review, but most of them is here now. SOme clock to clock comparison, win7 vs win8.1, more OC and HSA tests will be in official review next month.

 

First we talking about autooc. Asus give me 4200 MHz and 960 MHz at iGPU part. This is not bad. Nice things for beginners and people scared from BIOS settings .

 

3D Mark11

 

AIDA GPU test

 

wprime 1.55

 

 

 

Max stable OC for CPU and iGPU

In AMD Overdrive stability test I got 4544 MHz and 104x MHz at iGPU part R7. For CPU I needed decent 1.455 V in BIOS and 1.315 V for APUNB (iGPU). Im sue, 4600 MHz is possible, but with very high voltage. So I left only 4544 MHz. iGPU is very strong. Im limited RAMs. First low clock memory for this GPU engine and second Sammi from AMD told me about single sided limits for iGPU score. Unfortunatelly, my RAMs are single sided .

 

 

3D Mark11

 

AVP benchmarks - these benchmark is harder than real game of AVP. You can try it.

1920x1080, high settings, 16AF, tesselation

 

1920x1080, medium settings+tesselation

 

1680x1020, medium settings+tesselation

 

AIDA Memory and cache test

 

Wprime 1.55

 

Cinebench R11.5 - single and multi CPU score

 

Cinebench R15

 

Fritzchess benchmark

 

Truecrypt

 

x264FHD test in 1080P

 

Superpi 32M (as 5100 MHz Richland)

 

demonkevy666 wanted what about cores unit. I must CPU return back, until Il have new only for me . But I benchmarking two test for you

 

First 1CU/2C, so classic one module

All test I did with 4 GHz clock, Cinebench R11.5 and Fritzchess benchmark

 

 

 

Now 2CU/2C, so two modules with two active cores

 

 

 

We can see, 2CU/2C is really better!

 

 

Others tests:

 

3D Mark Vantage, CPU stable clock, iGPU autoclock

 

Cinebench R11.5 at 4645 MHz

 

Cinebench R15 at 4645 MHz

 

Fritzchess benchmark

 

Superpi 1M at 4793 MHz, I had run with 4850 MHz, but worse score...

 

Superpi 32M at 4799 MHz, this score is as 5300 MHz Richland , Kaveri is in 32M very effective.

 

What about power consumption?

 

I was not surprised about lower consumed number in load. But higher idle. Why? I do not know, maybe BIOS or board, Richland and Trinity I tested with another board...Remember, I use high PSU 1200W Corsair for test, with normal 350-400W PSU will be value lower.

After OC is Kaveri really quicker than OC Richland, in all test is winner, sometimes very clearly (wprime, R11.5, superpi, 3D Mark, AVP) and with lower power consumption.

Any chance of dialling in tighter RAM timings Michal ?

[flanker]

yes, I can do it . Waiting for nr2 chip
