I was interesting for Excavator for FM2+. Its fresh, new and I have not time for deep testing. Good news is, the TDP of this CPU is 65W and running most of time at 3800 MHz because dont reached TDP base.
So for you guys I tested Superpi at stock single RAM vs dualchannel 2133 MHz and quickly Cinebench R11.5 at stock. Next week Im doing at Wraith cooler review and going to holiday time to the mountain (at weekend Im out of my home also).


Athlon x4 845 has basic clock 3.5 GHz and include Turbo up to 3.8 GHz. The multiplier is locked of course, this is not K version. I used highend board Crossblade Ranger and 1702 BIOS.



As First 1600MHz DRAM in single channel and Superpi. Srry for 1M quality, its some bug of software smile.gif


- 17.581s at 3.8 GHz is better than FX-8370 at stock or than Kaveri a little. And we are still at single channel only...


- Superpi 32M is much smoother than everything from AMD. At 3.8 GHz single channel in 13m 6s. Wow, for this you need FX Vishera with dualchannel and some light tweaks at 5300 MHz or Kaveri at 4900 MHz!


What about if I put second modul, so dualchannel and set the clock to 2133 MHz at DRAM


- 16.317s is solid

- in 32M run 27s quicker than before! And result? Wow...As 5 GHz hard tweaked Kaveri or as 6 GHz FX Vishera smile.gif Lol, its my personal record at AMD AIR :-D


Its interesting, tke Kaveri and Excavator are more effective in 32M than i 1M.

Cinebench at stock is again better...Its in comparison as 4.3 GHz Kaveri smile.gif So in practice 500 MHz advantage.




But main question is...It will be able to overclock? I hope so...tried quickly light OC from BIOS to boot system....So, lets go someone try break AMD WR in 32M with LN2! Unfortunatelly, I have AHCI, so post with blck 115Mhz was not problem, but I got BSOD in Windows logo smile.gif With AHCI I can get into the WIndows max with 105 MHz, its not better than stock settings, cause your freqency without turbo is 3674 MHz..


Im sure, Zen will be clear winner, but we have still many months time and chance break AMD WR in SUperpi. This is the best bulldozer architecture for this one old benchmark...And hope, the BCLK issue wil be not with IDE mode

Wow, that's real nice. Maybe we'll get some more surprises before Zen comes out smile.gif

I'm a little bummed to see the Phenom II 965 still beating it in CineBench 11.5, but I guess that's still impressive for using half the power.

Those Pi numbers are impressive. I'll bet it's due to the faster/lower latency l2.

Watch this space for future . . . uh . . . stuff! Yeah. That.

because cinebench 11.5 doesnt properly recognise bulldozer and shouldn't be used to compare the two.

L1D which is double the size compared to any other 15h design probably makes the largest difference. Faster L2 definitely doesn´t hurt the performance either, only the Fmax.

Cool results. Gonna be interesting to see what OC you can reach under IDE mode.

Its sad, cause next week Im working at Wraith cooler review in free time and at the end of week Im out my home for few days. So IDE mode will be...I dont know-I hope in next month smile.gif

still we must to say. Phenom II is simply 4C/4T CPU, quad core in classic way. Bulldozers are Core Units. This is 2x CU/4C. So effectivity X cores will be always lower than classic cores.

Can anyone give the negatives of the BCLK overclock vs multiplier? How bad is using IDE mode over AHCI with SSD drives?
