APU Kaveri APUNB scaling in few tests

[FlanK3r]

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






CPU 4400 MHz APUNB 2000 MHz, iGPU 800 MHz
14m 51s/ 4.23pts/ 2783pts

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!

nice goin to test mine , just one question, what did you use to overclock it?

 

[DrMrLordX]

My guess would be that he did it in the UEFI.

yes, all in BIOS. If you mean cooling, its aircooling.

you can use to OC some next steps (for not much experience guys) :
Ez wizzard utility in BIOS

Or in Windows 5-way opt process.

ok thanks guys. on the next few days im going to upload some videos, im trying to record planetside, but the in-game recorder doesnt work, only records sound.
i will try some other programs, but lets see
playing with a 5870 have some stutters
playing with only apu is 768p, no stutters
and of course no ultra everything graphics settings
and also i put the phenom 2 965 socket am3+ air cooler i have, and it fit just barely.

I was surprised, iGPU at Kaveri beat in 3D Mark11 my older good HD 5770 with 4000 MHz x6 1090T. I know, its only 3D Mark, but still...
