3.5GHz Intel C2D is outperforming 4GHz Phenom, why?

post #1 of 28
Thread Starter 
So I am currently trying to figure out what's going on. I just upgraded from my intel C2D at an overclocked 3.5GHz to my AMD B55 (555 unlock) at 4GHz. All I can say is that my C2D is outperforming it, and I'd like to make my AMD faster.

http://valid.canardpc.com/show_oc.php?id=1862612
Intel Core2 Due E7300
3.5GHz
x8.5
Buss 412MHz
Rated FSB 1648.1MHz

http://valid.canardpc.com/show_oc.php?id=1859033
Phenom X4
4GHz
x20
buss speed 200MHz
HTlink 2000MHz
cpuNB 2600MHz

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!

EDIT: Cinabench is coming slightly ahead, core to core. Yes I know intel wins clock to clock, but I didn't put this on liquid to lose against the intel on ANY test. As for me seeing a difference on either performance wise, I don't. The core2 did EVERYTHING I needed and more. I could never ask for more than I had, I just wanted to build a toy n a budget that could beat it. It's more like a challenge than a complaint. And what better challenge than beating it at it's own game. Superpi!

Isn't SuperPi ran on a single thread? If so, architecture may play a role.

If your sole benchmark is SuperPi then you are being sorely mislead about which is "faster".
Bechmark things that matter, winrar, gaming, etc.

The Phenom's were always much slower at SuperPi.

Yes, single thread. I was mearly testing core to core one to the other. I'll try some more benches, as that's really disappointing. I do folding on both, and It appears that my intel does as good, if not better most of the time too. Don't get me wrong, a 4GHz X4 for $85 is a great deal (C2D cost me $120 2 years ago) but that's an annoyance. I'll come back ofter more testing.

1) SuperPi is HEAVILY, HEAVILY faster on any Intel architecture over any AMD architecture. Period.

2) Get your CPU-NB clocked higher. That'll give you faster benching, and faster overall experience. The higher, the better.

But yeah, if you're just doing SuperPi all day, then you went with the wrong upgrade.

Like I said, SuperPi is the wost benchmark you could use to compare performance.

If you do compare the folding post the results, I'm sure many here would find it interesting.

Phenom design was only ever supposed to compete with Core 2 Duo. They were just way late shipping. So now they've had to stretch out Phenom II, the die shrink, to try and compete with a generation of processor it was never meant to, which is why they sell them so cheap.

Still great chips for the money.

What's the highest CPU-NB safe volt. I got a "crappy" CPU and it needs 1.53vCore to stay at 4GHz and 1.4v on NB to stay at 2.6GHz

CPU-NB voltage you're good up to 1.45v. Vcore, you're good up to 1.55v.

You can, of course....go higher if temps are great (under 50-55*C load), and you've got the balls to do it. I ran my Athlon II x4 at 1.65v vcore / 1.50v CPU-NB for a good amount of time this last winter. Still clocks well to this day.

SuperPi is not a valid way to compare Intel and AMD, because SuperPi is vastly more Intel favored. Run something like Cinebench or games to compare, I guarantee your Phenom II will be faster, even core to core.
