AMD vs. Intel Pi Calculation Explained

lol Just looking for facts. I thought they were much closer
as far as performance.

Like I said, I have two AMD pc's and I'm very happy with
them.

Ps. It doesn't take an i7 to whoop a Phenom, apparently.

I wouldn't say they whip them at all. And at the price I would hardly go near the terms. Both of these exhibit an i7 maxed at 3.8ghz and a PII 940 at 2.64ghz. Videocard was the same 4870 X2.
Here's some farcry 2 benches -

Graph I: The first test shows i7 12% over PII, while at lower resolutions a 38% gain.
Graph II: i7 has a 12% gain, and then at lower (though still 1920x1200) resolution it has 25% gain.

However, here we see that both processors are more than able to handle games, where the GPU is the most processed. The Phenom II 940 actually BESTS the i7 by slight percents.

By the time our processors catch up to the 4870 x2 we'll have the 4890 to contend with, and so on until forever. If you're going to stress your graphics to the max, neither chip will make a difference, because they both are sufficient to fuel the super highend graphics card.

The AMD build cost $1300 and the Intel cost $1550, though they used a lower-end x58 board pricewise, and a bit costlier 790gx board, so the price will be a bit bigger difference.

So you'll be spending an extra near $300 for performance gains that have little real life noticeability. It's also noted that 1) Average i7 920 overclocks are anywhere from 3.5 stable to 4.0, while the PII 940 in this test (2.64ghz) was under clocked, as averages reach from 3.6 to 4.0 also.
The big deal on AMD right now is this - you have an Am2+ board and DDR2 ram already, instead of spending $400 off the bat , spend $150 on a cpu, spend money on ram and mobo later.
 
Very nice. Thanks for the time and effort you put into that post.

Like I said, I enjoy my AMD systems, and I would not hesitate to
recommend or use an AMD system.

I was just looking for some facts. I'm satisfied.
 
True, the two look pretty neck-and-neck in the gaming benchs but when you actually do things that require raw CPU power the story is different...

if you extrapolate that to the entire film length, the benefits become very apparent.

same here...

really ouch...

Yes, they are cheaper and an excellent alternative when playing games but if you are doing anything else, it seems Phenom II just doesn't cut it.

Well yes. But, for games, which is why most of us HERE buy them, other than massive internet dongs, they'll be fine. and IF you do need the raw power, you'll invest more money into it anyway. Notice however, the PII 940 and 920 both beat out the similar priced core 2 quads.
 
Regardless of the use, it definitely explains why the Intel CPUs beat out AMD in SuperPi, AMD CPUs just can't keep up when massive calculations are on the menu. I used to love AMD back when the FX CPUs were the best thing on the market. I wish they would get out of this rut they are in, so far they are just getting by with making mainstream performance CPUs and pricing them to compete with Intel.
One thing to note as well, you can't base your decision on overclocked benchmarks because nothing is guaranteed.

Yeah, i see AMD coming back up soon, at least near par with Intel market-share wise, then they'll have the ability to throw out $1000 chips again...
And those were the best gaming/real life i could find, all teh others i saw were similar, and i did note that they were overclocked, and the average overclocks saw, and so on.
 
Well yes. But, for games, which is why most of us HERE buy them, other than massive internet dongs, they'll be fine.

well, while we are trying to discredit the overclocked benchmarks simply because 1 or 2 people might not get those speeds, we should also note that myself and many other people here use their computers for photography editing (renders can be very CPU intensive), DVD encrypting, ripping, music and video files, converting, F@H... in all these things, having a processor made by intel can give you real (and very noticeable) improvement.

oh, by NO MEANS am i trying to say Intel isn't better. they are, but for the price, the performance is optimal for anyone that's in it for gaming, where the most stress is living on par to our extremely high end graphics cards.
 
Can someone please tell me, what's the deal exactly
with AMD's inability to compete in this thread:
http://www.computerforum.com/87599-post-your-superpi-score.html

Also explain how the AMD's even come remotely close to
Intel when people suggest the AMD chips as a viable
alternative to building an Intel system?

I'm sorry, but I just don't get it. I have 2 AMD system's
myself, and they work pretty good, but they're turds when
it comes to this program. What does this Pi calculation say
exactly about the processors ability?

(Disclaimer: I'm not trying to be critical, I would just like to know the facts)

The best score posted by an AMD chip is:
AMD: 24.672 - Phenom 7750 @ 3300MHz

My i7 clocked at 3.43Ghz did it in 12.33 seconds.

That's not even close, even with similar clock speeds.

What I'm looking for here is an explanation.

Congratulations on shaving 3/4 of a second off your score.

Your turd is still a turd. :D

Then why would anyone build an AMD system?

Then why take the test? lol

To me it's a real life calculation, and the Intel chips
smoke the AMD's.

Can you back up your statement?

Show me some "real world" results that prove that
AMD is as good as Intel. Within a reasonable margin...

That's all very interesting, but where are you getting this information? Could you link to these tests please?


Vista never makes me wait. Maybe it knows you don't like it. :D

@ Omega - Thanks for being honest.
All I'm after is some understanding, because until now, I thought
the comparison between the AMD and Intel chips was alot closer.

lol Just looking for facts. I thought they were much closer
as far as performance.

Do you just use your computer to run SuperPi ?

Easy there killer. :)

Nice contribution to the thread. Thanks.

And no, I don't just use it for SuperPi. It was just an
indication to me how much difference there was.

But it's obvious to me now that AMD holds their own
in a variety of applications. Thanks again. :good:
 
Well,the way i see it if everyone bought intel those things would be 400-500 a pop for a dualcore. so be thankful for AMD and your cheaper core2's and Quads-i-7 :D so everybody add an Athlon and a 2400PRO to your shopping cart and donate it to someone who doent have a Decent Rig or sell it for a doller on ebay and then that will help you also.. and for every other build you help someone with go with AMD by the time we are done AMD Will have a triple channel hyperthreading SpiderMonkey platform to compete with i7 and we win in the End!
