3 Ghz Athlon 64 Q1 2006
- Thread starter clarkey01
- Start date
With the FX57 @ 2.8 and coming out fairly soon, it'd be a shame for AMD not to have an official stock 3GHz product before years end.

I think the proper question would be will Intel ever catch up?
A64 = 9 instructions per clock
Pentium = 6 instructions per clock
3.0/6*9=4.5
A64 3.0ghz = Pentium 4.5ghz
And Intel has already stated they are not going to scale single core any higher than 3.8. And by all reports AMD dualcores will clobber Intel dualcores. So unless Intel pulls an unforeseen rabbit out of their hat, they are in a world of hurt performance wize. Not even mentioning the other advantages AMD has
Price
Ondie mem controller
Dual Channel > DDR2
Hyper Transport > HT (debateable)
Better 64bit performance
Let me do this for myself
2.665/6*9= 3.998
working on 2.7ghz now
2.7/6*9 = 4.050
I though ppl were saying an FX55 was more like a 4.2ghz P4
How does this translate with things like L2 cache, HT, memory controllers...I don think it can be this cut and dry.....too many other variables
I mean how about a sckt 754 1.8ghz vs a sckt 939 1.8ghz??? How can this formula work for all A64s??
How about 2.2ghz clawhammer w/ 1mb of l2 vs a 2.2ghz sckt 754 vs a 2.2ghz sckt 939 vs an up and coming Venice core 2.2ghz??? How do you figure SSE3 optimizations, 512kb more of cache, and dual channel memory controllers on performance. It must mean something or there wouldn't be like different PR ratings, right???
3000+ is 1.8ghz so 1.8/6*9=2.7ghz P4....doesn't work too well
2800+ sckt 754 1.8ghz works better.....so evidently you are missing some add ons for dual channel....
I think Zebo had a better formula that jived a bit better.
IN math and games it may take a 4+ghz to beat my 2.66ghz, but I know that in some heavily HT aware apps a 3.4ghz P4 cpu can do it

I agree the complete story is much more complicated, I was just trying to make the well worn point that mhz isn't even close to the whole story. I got a little carried away, but I am a card carring AMD fanboy
I use Intels at work because I have too
I use Intels at work because I have tooWhile this appears to look all well and good there is something you arent seeing. The reason why Venice and others are scaling so nicely, and why there is a 3ghz A64 on the horizon, is because they are lengthening the pipeline much like Intel did with prescott.
Granted not drastically but be aware, you are not getting what you think you really are. They will not be as fast clock-per-clock as the orginal design would have been. If anything they will be the same speed with SSE3 to make up for the shortcomings.
If you want proof go read the A64 article on the front page. AMD rep says such clear as day: "AMD *will* be increasing the pipeline stage to increase CPU speed"

How would you know?
Yeah, amd said they will, but that doesn't mean they have (seeing as rev E is already out in the form of the opteron 252s.)
Ive long suspected that E0 use a relaxed pipe. All signs from what I have seen point to it (this was before I went to intel, all fanboism aside). Here is what we know:
#1) Almost no difference in speed on SuperPI and in benches between them.. like 0%
#2) Higher heat. 67W --> 84W (whincester vs venice)
No one has come up with an explination to this... I cant either
other than they legthened the pipeline for 3ghz which was recentally announcedWhere are you getting that information from? I'd like to see a link, because I'm sure it can be explained somehow else.
I don't think AMD would extend the pipeline so much that it canceled out the clock frequency jump. Increased power is because of higher clock speeds probably. SOI could also make the chip need more power, but I'm not sure on that.

DDR2 is also dual channel, and will make a HUGE difference when Dual cores roll out, as opposed to now when the bandwidth isnt even used.
Hypertransport and HT have absolutly nothing to do with each other.

So where is your proof they have done this with the venice cores now??? I mean some pdf of amd specs??? NO one wants your assumptions...
Also why the heck would #2 have anything to do with what you are talking about???
Dude you spread more FUD and misinformation around here. YOU flyby and drop information for the most part you never seem to be able to back up. Give us proof and we will believe it...

That's pure speculation for now. Yes they said they will, but I think they were referring to the next major model change... the successor to the Athlon-64.
The "higher heat" could be the specification for the Venice core, not a specific model. If Venice scales to 3 GHz, of course it'll put out more heat than a 2.4 GHz Winchester. That doesn't mean that the Vencie core uses more power than a Winchester if clock speeds and voltage are the same.

Exactly....There is no logic in his thought!!!
