3.5GHz Intel C2D is outperforming 4GHz Phenom, why? - Page 2

post #11 of 28
Thread Starter 
Cinibench clocks in at 1.86 points for an X2 3.5GHz, and 4.61points for X4 4GHz. Now if my math is correct, I'd have to say that the phenom X4 is slightly better. Considering it has twice the cores, half the points need to be removed to make it fair. Also, it's 500MHz more on each clock. Like I said, not complaining, and still the best bang for my buck. Just found that funny that they had similar performance even with the intel 500MHz slower.

My 3 AMD folding cores are making
285ppd
288 ppd
947 ppd
(fourth core is not folding)

Intel ppd's
763 ppd
256 ppd

Whoops, did math wrong. It seems the AMD is a little better or worse depending on core. Not sure why the variance, but it is there. I may try to go higher on CPU and CPU-NB as temps are good. 50C socket with Rasa RS240 yate loon push/pull so I think I have room (all load prime95 stable)

You should be doing smp on the quad. You should get around 6-8k PPD that way.

Does SMp really do that much more for you? Also, does your system still feel responsive? I do SMP on my Nvidia 8800, and I'm told it's not supposed to lag (low priority, or idle, and not full usage). I've tried several drives, and didn't want to live that over. I just figured doing the same amount of work would yield the same points.

I can run smp on my CPU, and still game just fine (I do take a hit to my folding though). So yes, you can still run your machine just fine while smp'ing.

EDIT:
And I could do the same just fine on my Athlon II x4 630 @ 3.7GHz, and my Opty 165 @ 3.1GHz too.

Ah, I forgot the other reason I won't SMP on my CPU. My room gets hot. 2 things about my room getting hot.
1, I'm annoyed
2, my CPU gets hotter

I normally run 3 cores as it keeps it noticeably cooler in the room on every core that I drop. Darn crappy AC, in winter though I'll be better with OC's and temps as I can open the window

Your math is wrong. 1 C2D core at 3.5ghz gets 0.93, while 1 Phenom II core gets 1.1525. That's little over 20% faster with only 13% higher clockspeed

Also, yes I know I have more cores so it's still "faster" but getting beat in a superpi 2M digits by 4 seconds is pretty bad IMHO

Thanks!
stop using that crap superpi, its totally outdated

Devilmaypoop: Yea, it was close. It still beats the intel is some tests, so it's a close match.
pietro sk: Superpi just happened to be a test I ran on each. It's not normally by bench comparison. It's simply the reason I noticed it.

It seems that the phenom runs a little better core to core vs the C2D. I'm sure I need more tweaking to get more speed.

Clock for Clock, the Phenom II chips are slower than the Intel Core 2 CPU series. That just shows you how far behind AMD really is.

But in this particular case, SuperPi is single threaded, so that's why you lost.
