Hackintosh vs. MacBook -- very bad results


6 posts in this topic

Recommended Posts



I am using OSx86 since about 3 days and am very happy about it. But I mentioned that sometimes my system is a bit slow. So I have tested it wit the tool Xbench. I also habe tasted the MacBook of my girl friend. The Hardware of my PC is definitely better than of the MacBook but my system was just half as fast as the notebook according to the test.


1) My Hackintosh:


Intel Core 2 Duo 2,4 GHz boxed

Gigabyte P35-DS4

4 GB DDR2 800 RAM

Zotac GeForce 7300GT

2x500GB WD HDD SATA2 16 MB Cash

2x320GB Hitachi HDD SATA2 16 MB Cash

IDE Samsung DVD-RW

be quiet 400W power supply


Kalyway 10.51 +Vanilla Kernel + ACPIPlatform fix + MBR EFI + Natit.kext + HDA_ICH9_ALC888




2) MacBook


2,0 GHz Intel Core 2 Duo





Tiger ??



And here are the results, that make me so unhappy

By the way, the worse work of my PC I can feel sometimes, for example during writing tu a USB flash or searching a pdf document.



Can somebody make a test with Xbench on his Hackintosh and confirm my results? Is OSx86 really so bad? I have disigned my new PC for this system and see now that it doesn't work the way I expected. It would be a pity.

Oh, this looks much better than my results...

Does somebody have an idea what the reason could be?


I find it a bit strange, that Mac recognizes the CPU as 1.2 GHz. But I thought it doesn't matter. Is it possible that my 2,4 CPU works only with 1,2 Ghz? What could be the reason?

What's odd is that it recognizes that you have a Core 2 Duo, but it only seems to be using one core. (2.4 Dual Core having two 1.2 Cores.....)


I mean, I could see if it just recognized one core. That seems what it's doing. But to tell you that you have a dual core, but that it's only using one seems odd.

Have you got Speedstep/EIST/Whatever it's called enabled in BIOS? If so, try disabling it and try again. Saying this, Speedstep usually just drops the multiplier by an arbitary amount, for example if your CPU is an E6600 (which is 266x9 usually), speedstep will drop it to a x6 multi, which would still give you a 1.6Ghz core speed. Mine is running 300x9 at the moment (2.7Ghz) and steps down to 1.8 (x6 multi) in idle with speedstep.



Hmm. Thermal throttling maybe? If I recall correctly, under thermal throttling, the CPU has the ability to throttle itself down to a maxium of 87.5% lower than default speed, in 12.5% steps. If this is the case, yours may be throttled at the 50% step.


What are your CPU temps like? Can you test them with temperature monitor (in OSX), or preferably (for reliability) CoreTemp or intel TAT in Windows? Intel TAT is a great diagnostic for this kind of thing, it'll show you current CPU speed and temps, and also allow you to initiate a 100% burn to see what your max core temps are, and if you are experiencing thermal throttling at those temps.

Intel C2Ds, both cores are at rated frequency. Zalexs's C2D, even if only one core was detected should still show at 2.4Ghz. They are not rated by summing up individual core speeds. It's only AMD who still stick to the "rating" system, for example an AMD 64 X2 4800+ has an actual core speed of 2.5Ghz or thereabouts.

Thank you! I am happy again :P .


The problem was really in the bios settings. I didn't thougt about this because I tried not to change anything, but somehow I did it. So, now I have overclocked my CPU to 2,8 GHz and made the test again. I am very content with the results.
