Well, it won't. Intel needs AMD as a counterpart on the market. Anti-trust anyone? As long as AMD isn't a serious threat (and at 20% vs. 75+% isn't) they will let it live.various posters said:AMD is going the way of the dodo...

Mikael said:Agreed. It's hard to be impressed by a chip that seriously beats the G5 clock for clock, while reaching much higher frequencies. Garbage is what it is.
On point 2, here's very encouraging information from AnandTech:ksz said:I think some intriguing questions are:
1. Does Yonah already have 64-bit extensions? Someone raised this earlier, but I haven't seen a clear yes or no.
2. The new Mac mini and iMac have socketed (not soldered) CPUs. It's already been demonstrated that the processors can be replaced in the field. What is not clear, however, is whether we'll be able to replace Yonah with its pin-for-pin compatible successor, Merom, without needing to replace the chipset.
If (2) is doable, then (1) is a moot point. Just buy an Intel iMac or Mac mini today and replace the processor at the end of the year when retail prices are reduced.
Where did I say that? I'll buy a PC with Conroe this fall. Don't care when it ends up in a Mac. I'll look at an Intel based MacBook Pro the next time I buy a laptop, but that's pretty far into the future.itguy06 said:Do you really think Intel is going to PO Dell and HP, who make up almost half of the PC market by giving Apple a heads up on their fastest chips?
Well, I haven't disputed that fact, have I?itguy06 said:Look at it this way:
This is Intel saying our future chips will be faster than our competitor's current chips. Well, DUH, of couse they will be faster. Intel isn't going to release another chip like the P4 where it is noticeably slower than anything else on the market.
You're right, Conroe was shown to be faster than 20% in several cases, despite some 5% lower clock frequency. Even if Conroe's advantage turns out to be just 10% and a lower power consumption, it will still be enough to get back most of those lost marketshares. Well, unless AMD dumps their prices like in the good old AthlonXP days. We all know how good that was for business, though...itguy06 said:So, if Intel is claiming 20% speed increase (didn't look like that in Anand's tests, but I didn't bring out the calculator) than AMD's current chips, and AMD's new chips will be 10% faster, the gap is only 10%. IOW, you won't notice it.
I'm not the one that said AMD was going anywhere. I said the opposite. Seems you got us mixed up or something...itguy06 said:You also fail to explain away the increased sales AMD has been having for a long time now. People with new computers are not going to go out and buy a new computer this year because it's 10% faster than what they have. They'll buy a new one in 2-3 years.
We'll have to wait and see what AMD comes up with. I have a feeling it will be very competitive. Maybe not the fastest - it's about time Intel has something worth buying, but AMD is not going anywhere.
Yes, the G5 is likely faster at floating point. It is however probably slower on integer math. It's also worth noting that floating point performance without AltiVec isn't all that impressive. From the few tests I've seen, it can't really match an Athlon64 clock-for-clock.backdraft said:INTEL Duo does not beat the single core G5 clock for clock, hell the Intel duo has trouble vs the single core G4. Not to mention the G4 & G5 are at 90nm... Look at the floating point performance the PowerPC wins period.
Why? Barefeats just tested a 2GHz G4 versus a 2GHz Core Solo and although there were only a few tests that were totally CPU dependant, the G4 didn't look very nice in comparison. This is not the first test showing that the G4 generally performs quite a bit worse than the Core arch.backdraft said:I would rather see the Dual Core G4 in the Powerbooks vs INTEL Duo...

(iMac, iBook, Mac mini) and PowerPC chips for the pro's (Powerbook and PowerMac)
Mikael said:What's with this cult around old PPC chips anyway? The G4 is still a pretty nice CPU, but just like a Pentium III or AthlonXP it does show its ages these days.

backdraft said:INTEL chips are not better than PowerPC chips, Apple is forcing them upon Mac users and everyone is just jumping on the bandwagon blindly.

That is most likely not the case. The reason that Intel manages to get their Netburst chips to those high frequencies is mostly because of the very long pipeline. I don't know how familiar you are with pipelining, but, basically, the longer the pipeline you have the shorter the signal delay between each stage and the higher you can go with the fequency. Just look at the differences in max frequency between Yonah and Dothan compared to the P4 and Pentium-D. The former use a pipeline length similar to the 970 and they are also able to run at about the same frequencies.ehurtley said:If Intel was to take the design for the PPC970MP, and re-jigger it for their manufacturing, they could probably get it to fly at 3.5+GHz.

Thank you, but it's really a moot point.ehurtley said:No.
Hell no.
This was indeed clearly answered.

DavidCar said:It also looks like it will accept the next generation Woodcrest chips in 2007, which I assume means quad core.
I had to go look up a Wikipedia article because I don't have these names memorized. According to that, Kentsfield will be the four core version of Conroe, while the four core version of Woodcrest will be called Cloverton, or Clovertown depending on which article you look at.~Shard~ said:You mean Kentsfield?
See post #80 in this thread.DavidCar said:I was trying to find a source the $850 Woodcrest price but couldn't.
Thanks for the reminder. I remember seeing $850, but forgot it included a link. I agree with your point there that Apple would want the new PowerMac to be priced about the same as the current edition. Checking the link gives me hope for a lower Mhz version at a lower price.ksz said:
I agree ScottB. And the 64-bit advantage will make waiting for Dual Core Merom in a 17" MBP logical to all but who must have faster portables NOW. I for one will wait for a Merom 17" MBP before I pull the trigger on my first MacIntel portable. I don't really want a 32-bit processor in a portable when I am driving four 64-bit processors on the desktop already.ScottB said:I think we will see the Merom going into MacBook Pro's almost as soon as they have been released.
http://www.anandtech.com/tradeshows/showdoc.aspx?i=2715&p=2During a separate briefing, Intel's Mooly Eden showed a benchmark pitting a Dell Core Duo system against the same system with a Merom processor (Eden literally swapped out the Core Duo CPU and stuck in a Merom processor, partly to showcase its backwards comptability).
