ExtremeTech: 3.2Ghz P4 vs Opteron 2Ghz

[SJJM]

I would not say the bandwidth would make the difference, it more like the lower latency. I thought is why they design the chipset the way they did, so that it has lower latency.

That'd make sense if Hypertransport provided lower latency than the traditional point to point bus on the K7, but it doesn't. AGP has never been particularly sensitive to latency anyway.

Dave in the GFX Forum may be raising a point from a paradigm to this here. PCI-Express is great deal for graphics because the CPU to GFX card performance is often very weak. According to him, PCI-Exp will change that, and as he is a GFX Programmer, he seems to have experimented or seen actual proof on how performance is weak with AGP 8X at the moment. One could perhaps assume HT helps the CPU to GFX transfer much more than AGP 8X does.

I might be babbling though as I forgot most of what Dave said.

You raise a good point on the ES' reviewers get. My best guess would be (since chips need 3 months of testing, which would mean that if they recently solved the issues, it'd take time before they are out) we'd have to wait for faster FX 64 versions.

I'd be interested in seeing if it did help.

Ya Kelledin 128 single precision instructions are so damned easy to implement in native 32bit core. What is that hmm 7 million transistor increase to core overall transistor count then we add the register, new access ports, additional prefect module ports, bus ports also we cant forget the power consumption increase. Also the skew lvl's due to the change in core tick sync. Its funny dude you have no damned clue on semi conductor architectures do you? Easily implemented my ass sounds like a fagboy AMD fanboy playing down the poor engineering form AMD as usual.

You’re a funny guy kind of funny how I was right about the Northwood core smoking da shiznit out of the Athlon and scaled as well too. It’s also more quaint you show up when the hybrid is about to beat up on my beloved P7. Buts it’s all good the Prescott’s coming . You’re a bad bad man Kelly!!! I like it that way just like when Eden talks dirty to me .

That's why I pointed out, the first K7 core taped out with the basics of an SSE implementation, it was just left "turned off" for the most part. The silicon groundwork for XMM registers and access ports was already in place before Palomino, so turning it on wasn't that big of a deal. All the skew level testing and layout optimization was being done anyways at that point, because the T-bird's power consumption was getting a bit high.

But of course, the groundwork for SSE2 couldn't be laid back with the original K7, because SSE2 didn't even exist then outside of Intel's labs and dreams. I believe that's at least partly why we never saw SSE2 on the K7 core.

First-revision production Opterons, on the other hand, had a fully functional SSE2 implementation, but it wasn't fully optimized for speed. AMD already committed to improving that. The AMD64 optimization manuals state that it's fixed in a specific core revision level, but there are doubtless a lot of reviewers outside of AMD that don't have the revised part in their possession--or if they do, they can't talk about it. Seeing sites having to base their AMD64 previews on Opterons <i>overclocked</i> to 2GHz is fairly telling.

Its funny dude you have no damned clue on semi conductor architectures do you? Easily implemented my ass sounds like a fagboy AMD fanboy playing down the poor engineering form AMD as usual.

My god, I've been ad-hommed.

The pain! The pain!

Oh wait...that's just indigestion. Never mind. :lol:

You're a funny guy kind of funny how I was right about the Northwood core smoking da shiznit out of the Athlon and scaled as well too.

Yup. What do you expect? The Athlon was made to compete with and crush the P3, which it did very well. Even put the Willamette to shame after that. But of course, you (and the other Intel zealots) could never admit that...

It's also more quaint you show up when the hybrid is about to beat up on my beloved P7. Buts it's all good the Prescott's coming.

Oh, I've been around.

As for the Prescott, yes, it's coming. Faster AMD64 parts are also coming. May we live in interesting times.

Was there really someone who couldn't admit that the Athlon put Willy to shame? :O I want proof. (I need a good laugh at a zealot's expense. He he he.)

Though technically I'd argue the semantics. Willy more or less put himself to shame. No one needed an Athlon to do that. Heck, even the P3 did that. **ROFL** Poor Willy... It could have been worse though. It could have been a Wilty. :O Imagine if Intel had cut the cache like that from the beginning... Ooooo... He he he he he.

I hate to rehash old characters...but remember FUGGER? He was probably the worst of the lot. Actually went so far as to stupidly fabricate bogus test scores a few times. His infamous 3DMark2K1 score thread is probably still in the archives somewhere--even most of the Intel fans were calling BS on that one.

AMDMeltdown is/was just a troll. His arguments were so off-base, I doubt he even believed them himself.

Considering Matisaro is gonna be around soon, it wouldn't make any better entrance and welcome here than reminding him of Fugger's 3dMark01 thread in which he put his entire convictions on with arguments and used it dozens of times in debates!

Not soon enough it seems...

Ignorance has kept your mind closed to the thruth my friend. My scores were real, I never faked anything so you claim. I have never stopped pushing.

Rather than flame you with hate, I will let you ponder the possiblility that if my scores were real and I put up with all the crap...

<A HREF="http://fugger.netfirms.com/45ghz.jpg" target="_new">FUGGER @ 4.5Ghz</A> on my gamming machine.

2 years page 1 on 3Dmark (in the top 10 + hall of fame now), one of the world top 10 super pi, #6 world overall, #1 non Ln2, and you still doubt my score when I rebenched and was off by what? less 100 points?

I am glad you guys still think of me.

I was outnumbered badly, yet I survived.

Matisaro was the grand poobah of the zealots, and it showed.

Looks like you are still keep the flame lit for him.

Thou still dost protest too much.

We mainly remember you "conveniently forgetting" that your vidcard was overclocked, then frying your vidcard trying to get the scores you claimed. That little debacle will probably haunt you forever, no matter how well you can push it now.

All great fun, at least for the spectators. :lol:

Nothing to haunt me, my life does not revolve around this forum.

Its amazing how you regurgitate what fagboy fanboy spoon fed you so long ago. Now we know you dont swollow.
