AMD hit 3 gig SKT F / L1 cpu on sale

well im imagining multithreaded apps will be mainstream before 8 gig cpus by a long way

Doubt it Zing... I'm a developer and companies dont give a toss about effecient coding. Besides a single core is fast enough by itself and why build faster and more efficient coding when you dont have a direct competitor.

Some apps will have to go smp of course due to stiff market competition... Also how much is Vista internally tuned to running under SMP vs single core anyway.

Its down to market forces and those with the wedge make the desisions. Anyway Intel couldnt even break 4 ghz with a stock cpu and no they are under 3 ghz so I dont see 8 ghz happening in a hurry as has been proven there is just to much heat and to many problems why else did Intel change all its plans? it was for fun it was because they simply couldnt hit 4 gig with a cpu they could sell retail at that speed.
Ive championed multi core computing and I will continue to do I was proven right when AMD released a dual core FX cpu and I seriously dont see me proven wrong and if I am it wont be for years so ill worry about it then

Mate dont get me wrong but SMP rocks My 5 year old dual Pentium 3 servers are like only a third off the pace with todays core 2 duo.

As I keep saying, getting the masses to go from 1 core to 2 core will yield them great results and benefits (partly due to windows INEFFICIENCY / deficiency or just plain old user incompetence

And so selling the sheep quad core should be easy but unfortunately will not yield as good a performance leap as going from 1 to 2 cores. Unless of course there will be new hardware and software made available to make full use of quad core.

No point continuing time will be the desider. One things for sure computing is still a baby imagine where it will be in 20 years

I hadn't heard that, but then I've still got a bit of catching up to do on my tech news feeds.

I noticed that in 1 of the Quad FX articles I read, then again it was based on the assumption of using 2 Nvidia cards in SLI mode. Personally, I could live with having only the 1 [ATI] graphics card, as it's more CPU grunt that I need. Having said that, the [yet to be released] Saphire "Crossfire on a card" X1950 Pro Dual does look rather nice. [img]Download Failed (1)[/img]

I can't help but wonder if the Socket F Opterons [2000 & 8000 series] might not have the same problem, as in reading reviews of them I don't recall seeing it mentioned.

I could be wrong, but I think the 2000 series have 2 HT links [1 to their own RAM, 1 to the other CPU], & the 8000 series has 3 [1 to their own RAM, & 1 each to 2nd & 3rd CPUs]

It's supposed to be a lot better, in terms of the scheduler assigning threads to cores, than XP, but only time [& reviews ] will tell.

I have to [grudgingly] admit that some of the stuff in Vista looks nice, for example the ability to make thumbnails in a folder bigger or smaller with a slider, & also the ability for the search funtion to whittle down the listed results as you type in the search box, similar to the 1 in Thunderbird.

Other than those 2 things [which I reckon should be able to be added to XP by a 3rd party app], I don't really see a compelling reason [for me] to switch to Vista. I'm also not happy with all the DRM/TPM crap in it.

Well, they're still listing them. The American site [I'm assuming you were referring to Newegg?] was still listing them yesterday as single CPUs, though there was some mention of them having to be purchased as part of a bundle, so it looks like they may be caving to AMD's demands whilst trying to make it appear [to the buying public] that they're still selling them seperately.

No, they're AM2 X2 cores with the HT links enabled [IIRC standard AM2 X2s have the HT links disabled].

Just had a quick look on the AMD CPU comparison site, & compared 2 CPUs: the FX-70 & the Opteron 2218 [both 2.6Ghz, both have 2x1MB L2 cache]. Even though they're both made with a 90nm SOI process, the FX-70 draws 125W - compared to the 2218's 95W. There's obviously something different there.

I may be an AMD fanboy, but I have to admit they do sound nice. Mmm... 8 cores... [img]Download Failed (1)[/img] [yes, I do use a piece of software that would take advantage of all of them ]

I know of a company that does... or does now anyway [they coded themselves into a corner with the previous "architecture" of their software, & had to start over from scratch].

I don't know any specifics, but I keep hearing that 2 or more cores are definitely recommended.

Oh, & on the clock speed issue, for whoever was saying that higher clock speeds were not too likely any time soon - somebody managed to get a a quad core Intel to 5Ghz, & a dual core Intel to 8Ghz... admittedly they had to use LN2 in both cases, but they did it. Also, IIRC, IBM's latest PowerPC chip - the Power6, weighs in at 6Ghz.
