Pentium 4.0ghz Outdated??

[clarkey01]

Intel has 10 Ghz runing in some fabs.....


A Bird told me.

Malak, in short no. Dual proccessors can't take advantage of it all the same way SLI does, you can't realiably split instuctions in 2 and hope for them to come out at the exact same time on the other side of the processors.

having a single transister running at 10ghz is alot different than having a chip as comples as a p4 run at 10ghz

No I mean if the same rig had both SLI and dual core procs. One core working with one video card. Possible potential for more power?

Well he works there, in one of the fabs.

I think the main difference is a video card is very capable of rendering just half of a screen, and having both halves come together at roughly the same time.

Remember a cpu is doing a whole lot more than rendering a scene, it's taking care of AI, physics, in some cases sound calculations, and other background processes. There isn't a really good way of just letting one cpu do half, and the other cpu do the other because the work of one processor will be dependant on the work of the other processor, so they can't just keep going along.

i don't think dual 2.5 woud be equivalent to 5 ghz?

Sony is working on a 4.something ghz CPU for the PS3. They say they have it running in labs.

That is the cell processor, and doesnt execute code the way a traditional x86 cpu does (AFAIK). Intel has had 10.0ghz ALUs running in their labs (over a year and a half ago too). Does that mean its going to be out soon?

This wouldn't really work, because games don't work so that the CPU prepares an image and then the graphics card renders it. What really ends up happening is that the graphics card does almost all of the graphics related work, while the cpu has to do the phisics, AI, etc.
Also, this would only work on games designed for a dual core/dual proc computer, in other words they have to be multi-threaded. Current games are single-threaded, meaning that they have one continual line of instructions for the CPU to process and each instruction has to be processed before the one after it, so you couldn't send all the odd instructions to one core and all the evens to another.... but it would be nice if you could .

There are a few titles that are SMP aware. Star Wars Galaxies and EQ2 and Planetside to name a few. I believe the Doom 3 engine is supposed to be SMP aware as well, but that was during the every rumor came from carmack himself type of days so i think that would have to be tested.

oh wow i cant wait thill they get to 100ghz and even 1000 ghz!!! goddamn this is an addicting shiz!

Get up and do stuff in the meantime - it's gonna take awhile .

People should not underestimate intel. They had 4.5ghz like 3 years ago and I even remember an article with pictures from one of the computer shows with a 10ghz processor.

That was a 10Ghz ALU, not a 10GHz CPU, big difference.

The 3.8 Prescotts are getting to 4.2 on air, so they weren't all that far away.

They certainly could have released a 4Ghz Prescott, but I am glad they decided to redirect their efforts elsewhere.

On what kind of air? $40 4kg copper HSF? 5000rpm 92mm screamers?
How much power?170W?
How much lost CPU cyles due to thermal throttle?


Face it, a Dothan derivative is intels future. Not these loud, expensive to cool, expensive to power hawgs. I'll be buying some kind of dothan the day they come out with DDR, 800+FSB for my silent game box. Even AMD will look like smokers then.

There it is right there IMO, the OEMs were doubtless not very excited about having to pony up for the necessary cooler and PSU they'd have to use with a Presscot 4ghz system, or how difficult it would be to keep it semi-quiet in the process.

I think they scrapped 4ghz partly because of OEM resistance to the cost factors and the fact they see the mobile market as the next big thing, and it is. There be gold in them dar *mobile* hills!

Zebo, it was the stock fan in the review. They had it to 4.3 but it was not totally stable.

From firing squad's review:

"Using the D925XECV2 motherboard and its latest BIOS, which fixes a problem with Intel?s burn-in mode, the 3.8GHz Pentium 4 scaled up to 4.3GHz ? the highest setting available ? without crashing. It didn?t prove to be as reliable in games, so we dropped it to 4.2GHz, where the platform worked without issue."

Face it, Prescott was never as hot as it's rep, and the newer steppings are no worse than Northwoods.

- Excuse me? There are no changes to the newer steppings other than more throttling devices. So if it's not hotter, then it's not faster either.
There's no reason to believe that chip actually ran at the set 4.2GHz. ...Or to believe that it would still run at 4.2GHz after an hour of full load.
The technology of reducing heat by reducing performance have been available for a good while in cheaper and more consistent form: 2.8GHz and 3.0GHz

That sony chip sounds pretty sweet, the problems that I see on first view (I haven't done any research yet) are x86 support (eg. would it be like Intel's Itanium2 that has completely different instructions so it can only run certain very uncommon software) and sony's production capacity. I doubt sony has processor fab capacity anywhere near either intel or even amd (anyone know?) so it probably couldn't sell the chip to PC consumers as well as ps3 consumers.

It would be cool though, I gotta do more research on it.

It's actually not a "Sony" chip. It's IBM's Cell Processor technology. Which is based on multiple "lean" Risc cores. 'Power' derivate. It's to be manufactured by another Japanese company, Toshiba, Matsushita, Mitsubishu, forgot which...

And you're right, it cannot run mainstream OS'es or software. So forget it. Also considering the rather steep performance (really), not to mention performance/price of current and planned '86 PC CPUs from Intel and AMD, I'm not sure it would even be competitive.

I was at Computer Wizards and I was talking to the owner and a bunch of technicians,
and they said that Intel isnt even going to release a 4.0ghz CPU at all, and that they are
skipping straight to 5.0ghz . Anyone hear anything else about it?? is it going to be 128 bit??

What the heck kind of computer place is that? Don't they read?

The GHz race is officially over....DEAD. Anyone that knows computers has had that knowledge for over a month now. AMD basically won with a better architecture and now Intel is moving in that direction. Basically, Intel has admitted that clock speed is not what computing should be all about....it's somewhat meaningless with today's CPUs. It's just too bad it took Intel so long to realize that 100+W is just too much for air cooling.

All I can say is: GO PENTIUM M

I'm actually considering one of those 6x0 P4s with 2MB L2 and EM64T, - with a kg of copper, of course.
But I'll see what it cost and how it performs first. But the Nocona results are not too disappointing.
AMD is better of course, so I'll only get it for the ht and media encodes. - And variety, I suppose
