I tested few days ago new ROG board Asus Crossblade Ranger and with my alone A10-7850K chip I would like how good is 7850K with different APUNB frequency. Ussually are Kaveri lazy go higher than 1950 MHz at APUNB... I tested it in Superpi 32M, Cinebench R11.5 and in 3D Mark11. So...

 

CPU 4400 MHz APUNB 1800 MHz (stock), iGPU 800 MHz

15m03s / 4.20pts/ 2758pts

CPU 4400 MHz APUNB 1900 MHz, iGPU 800 MHz

14m 56s/ 4.21pts/ 2768pts

The 2100 MHz was not possible get stable for 32M, so I must set differents values near the 4400 MHz. Of course, the iGPU is now at higher clocks than before (816 MHz). CPU a bit lower frequencies.

CPU 4385 MHz APUNB 2040 MHz, iGPU 816 MHz

14m 46s/ 4.19pts/ 2835pts

So we can see nice improvement in SUperpi 32M. +100 MHz at APUNB is similar as 400 MHz APUNB at Richland! In last case with lower CPU clock is 32M again better than before! +240 MHz at APUNB bring you -17s at least. For CInebench are little extra points - with exactly same the CPU clock +0,03 points and in 3D Mark (only three results, not the last one) +23 points.

 

For fun, my average chip and 32M run:

This CPU is very good in 32M, some 6.1 GHz LN2 chip could hit around 10min 32M or less!
