A weakness in Core 2's armor?

[Carfax]

There's been alot of controversy about Core 2's 64-bit performance, and while I would go so far as to say that Core 2's 64-bit performance is fairly good and much better than the P4's, it's still not up to par with AMD's.

Also, it could be that AMD's 64-bit compilers are just much better than Intel's, or that the programs themselves were optimized for AMD64 alone seeing as AMD64 was the first x86-64 implementation, and not Em64T..

64-bit benches



All in all, even if Core 2's 64-bit performance isn't as fast as AMD's, 64-bit won't be much of a factor in the mainstream for 3-4yrs..

[wwwww]

Core 2 looks faster to me in both 64bit and 32bit.

The 2.93 XE is what's supposed to compete with the FX62 and it beats it quite well.

use the search tool. benchmarks have already been run comparing conroe to amd64. conroe has a large lead in 64bit performance similar to the one it has in 32bit.

Your saying the fx-62 (the highest end AMD chip) vs the lower end Core2Duo, is a suprise that the fx62 wins?

[AndrewZorn]

yeah, if you want to be 'fair', its highest vs highest

but if youre bragging, its lowest vs highest, hahahaha
cant wait for my connie

[highoctane]

You can also look at it as maybe AMD's 32bit performance just isn't as strong as Conroes in relation to 64bit performance in this particular app.

[Eastcoasthandle]

AMD 64 and AM2 have increased performance in 64bit OS. C2D only marginally increases in 64-bit but it doesn't loose it's prawls in 64 bit OS as it performance lead in 32 bit OS. Therefore, C2D still comes out on top, even though you don't see a leap in 64 bit OS apps. There...happy now?

Dude did you even look at this chart? The only thing Althon 64 FX-62 beat at over $1000 is a 2.4 C2D
Unless you are being sarcastic..

I don't mean to sound like a Intel fanboy( I'm not, what ever is best is best,period) BUT did you bother to even look at this chart before you posted it?
The only place I see that AMD beats Intel is AMD's fastest cpu on 64 bit vs Intels slowest on 64 bit..Everywhere else Intel is beating the FX62..
Maybe my eyes are too old and I missed something here??

The important thing here is not that Conroe is faster than AMD, but that Conroe's 64 bit performance is worse than its 32 bit performance.

Trust me, In 64 bit cinebench, the FX62 is equally as fast as a x6800 at stock clockspeeds.

no, unless i read it wrong he said in plain engrish that the lower clocking conroe beats the FX62... and that my dear noob of leet its a bloody down to earth fact.

end of story its been proven over and over and over... even the lower clocking E6600 beats an FX62..

I see your point..I also see that the Intel beats the amd's performance in 64 bit with both the middle and top cpu...
I will take your word about cinebench, I have no reason not to..

Trust you? Someone who's been running a mock on the Intel forums with AMD propaganda? Surely you joke? I am sure it won't be long before you start preaching that we are lead a stray and you...messenger of the Ori are here to set us on the right path to enlightenment?

[ssnseawolf]

Hmm, that's pretty odd. I'm voting a combination of poorly optimized compiler as well as a poorer 64-bit architecture.

hmm, ok, since there is new info listed here..you said trust you..
I assume you have a FX62..
I'll toss win64 on my 2 core Intel and lets see what happens..and my 2 core intel is a lot slower than any new conroe..this should give us an idea anyway..You game?

[[XC] DragonOrta]

Where would I go to get a 64-bit version of Cinebench? I've never run it before, but I might be able to do an XP-64 install tomorrow and let you know how it goes.

Did YOU bother to look at the chart? As did EastCoasthandle?

The benchmarks show that Core 2 is SLOWER in 64-bit mode, compared to it's 32-bit performance..

The K8 GAINS in 64-bit mode, compared to 32-bit..

Yes, Core 2 is faster than AMD in both 32 and 64-bit, but the point still stands..

Core 2 is SLOWER in 64-bit than in 32....atleast in these benchmarks and the others in my link.

[Disposibleteen]

It could just be that Intel has not taken 64bit optimization on desktop CPUs that seriously yet becuase they know that it is a rare few desktop users that run a 64bit OS.

Yes, I did look at the chart..
What it shows me is that the middle and faster models from Intel are both faster than the amd in 32 bit and in 64 bit in those benchmarks..
Please find something wrong with that statement.

Technically Movieman is correct because he was argueing with your statement saying that the Core 2 Duo's 64bit performance was not on par with AMD's K8 64bit performance when in fact the Core 2 Duo whips AMD's 64bit performance by a fair margin.

hey stupid the lower the score the faster it is .. for s sake YOU read the chart

[KenzoIX]

hey stupid the lower the score the faster it is .. for s sake YOU read the chart

Read the 16th post

[derektm]

I think the point was AMD's performance increases with 64bit and Core 2 Duos doesn't. It gets worse.

Wrong, Conroe only beats K8 64 bit in this app.

I posted pics of my 64 bit cinebench in the other thread, and a 2.8ghz dual core K8 is just as fast as a X6800 at stock speeds.

I would love to have a smart conversation about this, but I do not like the rampant flame baiting.

Where would I go to get a 64-bit version of Cinebench? I've never run it before, but I might be able to do an XP-64 install tomorrow and let you know how it goes.

It is in the exact same folder the 32 bit cinebench is in, both 32 and 64 bit are in the same file

Just google cinebench 9.5

I hope you weren't refering to me on the flamebaiting. Not my intentiion at all. I also didn't see the other thread you refered to. Can you provide a link?
I'll install win64 here and run it to see how it does against your benches..
Thanks!

No need for that.... I dont think you understand the thread.
