Prescott almost here

Planning the same... Prescott 3.0 to about 4.2 Ghz on air. Far from impossible, considering the overclocks of some newer 3.2 Ghz Northwoods.

Are you serious? That is some exponential scaling we're talking about...

Not really, hardcore(lucky) OC's are currently getting 3.5-3.6+ on air cooling and 3.8-4.0+ with vapo, etc.

So for me to expect an extra 400Mhz from current 3.6Ghz OC to 4.0Ghz isnt too far out of wack for a die shrink. They're supposed to be running at like 1.3v
 
It would be really funny if Intel Decided to lock the FSB so you can't overclock.
 
Discuss the hardware gentlemen, not being Trolls or trying to stir up problems in the forum.
Cross posting is usually a bad idea between the AMD an Intel forums. If someone is acting like a Troll simply ignore them, don't feed the Trolls. If they're being a problem PM or e-mail a Mod or Admin and we will handle it.
 
speaking of Forum trolls. I know an admin(not here) who used to investigate the IP addresses of some trolls. And found that some people pimping certain hardware sites... coming from the IP addresses of their companies. Unfortunately, he never exposed them like he should have on the front page!!

Ex: Troll saying: yeah, xxxmicropc.com has great deals on widgets.
Then you notice the IP is of an ISP service in the same city/state.
So contact them through website & their reply (via email) reveals the same EXACT IP address as the forum Troll.

Not saying wrench is an AMD employee! Probably just a fanboy who likes to crap threads.

But saying that some forum trolls pimping certain places... or complaining/discrediting about others.... especially with low post counts are probably biased trolls that need to be ignored!

And how the hell would Intel go about locking the FSB so you can't overclock? The FSB is a physical bus between the cpu, northbridge, and RAM on the motherboard itself. The processors are manufactered to run at the speed designated by the system clock on the motherboard x their multiplier. The motherboard handles the FSB not the Processor. And even if Intel could they never would. And if Intel did it then so would AMD because look at how they follow suit with everything Intel does. First they marketed unlocked processors as a whole but they finally learned they weren't making money off doing that because too many people were buying the slowest processor in the lineup and overclock it faster then their flagship processor. AMD has now started locking them to prevent it. AMD also decided they would include Intels SSE2 instruction set into their new A64's because Pentium 4's were walking all over Athlon XP's in the majority of benches because most things now are SSE2 optimized.
 
I am also looking forward to the prescott 2.8 now that it is confirmed that the p4p800 will run it :)

Wouldn't it be cool if AMD did the same? Hmm...what kinda B.S. Troll statement is that? It's kinda like someone talking about the wonderful weather and you piping in and saying something about water treatment. Get a life...
 
I wonder if it really will be released in February... Usually they have reviews early right? I don't see much of anything besides this yet... I just sent my p4 2.4c back to newegg because I'm going to wait for this baby. The only problem is I have an Asus p4p800 mobo sitting here brand new until they release the prescott's!
 
Poopyface, horrible name! :)

Did you try that 2.4C out first to see what it would OC to?
I HOPE SO!! You might have had a wonder chip that OC's to 3.6 at default voltage.

Where Prescott's MIGHT not OC well. They may be performing similarly to Northwood at first until they refine the process. (like initial northwoods were only good to 2.5+ and some people had Williamettes clocked that high)

Just saying it MIGHT not be great. I'm hoping it is!!

P.S. Have you tried using 2-2-2-11 timings? Everyone says it gives the best performance on Nforce boards.
 
I didn't even try it I got a horrible one anyways, I could tell because mine was made in the Phillipines... But anyways I have tried 2-2-2-11 and that works great but I don't think it is any different from 2-2-2-5. I sent that CPU back already and now I am waiting for the Prescott release.
 
What was the fastest CPU last year? P4 3.06GHz...and this year? 3.2GHz...thats 0.14 difference wow...

Doesn't follow Moore's law does it?

I've heard Intel is going to release Prescott but it will be replaced 6 weeks later with a later one so I think there is no point purchasing the Prescott... (IMO)
 
No, there is a point in buying a Prescott. If you have a intel 478 chipset that is the best way to go because the new processors are going be on a new chipset and pin orientation. They are going to be unbelievable so don't get me wrong, but they are going to be so expensive considering they require a new motherboard and they start at 3.6ghz which makes prices start at: up the asshole.
 
Probably just as expensive as those that are going the AMD64 route. New borad, new processor, memory etc. In all reality though there will be a whole new chipset refresh this march/april. So it doesn't exactly make much sense for those that don't already own a prescott ready board. Then you could be the talk of the block with the first pci express card running a r420. (or nv40) :)

Where did you find this information? I'm curious as to see if my Asus P4C800 Deluxe (not the -E version) will run the Prescott chips. I know at release, it was supposed to but..
 
Same thing here... though I have a P4P800. I bought this for the Prescott compatability when it was first released (remember when the Prescotts were supposed to be out Q2 of 2003?). So, 6 months later, I'm still sitting on a 3 year old processor. Granted, the board helped tremendously over my old P4B266, but still, I'm gonna be mad as hell if my board doesn't support Prescott.

Yeah, your board supports it... I don't want to go search the link again though. It is official from asus - goto www.asus.com and search for Prescott and you will see that it does.
 
I hope the Prescott's come out on time because I just bought a P4P800 just for them and it's just going to sit here in the meanwhile...

You might want to read into this, though I haven't gone over it in a while (basically all I remember of the patent is that it's an anti-overclocking measure). It might just dictate the internal frequency so that the FSB set in the BIOS still remains, but then there wouldn't be much of a point to overclocking (only increasing mem bandwidth).

Hopefully the 2.8 prescott is another 2.4c and with 1meg of l2 cache it will be seeing my hard earned $$$ long before amd;)
And is prescott shipping with sse3 and ht2 :confused:

Yes, it will have both of those features plus more.

But how much difference is that extra cache going to make on the desktop platform vs it's cost ? Look at the P4EE vs the standard P4 3.2, does all of that extra cache really make it worth the extra cash ? I don't think so. How about performance numbers. Certainly the EE performs somewhat better than the standard 3.2, but is it really that much more ? Also how about the A64 3000+ vs the A64 3200+, same core speed just 512K of L2 vs 1 meg L2, (kinda like what Prescott is bringing over Northwood). Is there really that much performance difference for CPUs that are almost twice the cost ? 1- 5 % is really about all. I realize Prescott's cost is supposed to be pretty close to the current NW, but then I'm not expecting too much performance difference at the same core speeds either, based on what I've seen in previous cases.
 
prescott will perform around 5-10% better per clock cycle, according to some benchmarks floating around. this is a very significant jump.

The performance of the extra cache wont always give a big boost in every benchmark or game but in some areas the extra cache gives a pretty descent increase in performance. The only real difference between the 3.2 and the 3.2EE is the 2MB L3 cache. The 3.2EE wins in almost every benchmark against the 3.2, and sometimes by a pretty good margin. It even beats the FX-51 in half or more of the benchmarks while the 3.2GHz cannot at stock speeds. If they could make system memory that could keep up with the processors demands then they wouldn't need more cache but to this point they havn't been able to. I dont think prices of the northwood vs prescott are going to be much of an issue because the prices aren't much different then that of the Northwoods when they were first released, even cheaper from what it looks like on some of the sites thats showcasing them. Especially considering their core clock speeds.

I dont know if they care calling it SSE3 and HT2 or not but Prescott is supposed to have an SSE3 new like instruction set with improved hyperthreading.

Very interesting read indeed. I wasn't aware of Intel's forture thoughts of implementing such features. It seems like between things like this from processor manufacters and BIOS creators like Phoenix trying to control everything you can do on your computer, people dont have rights any more at all.

Intel is also pushing Extensible Firmware Interface (EFI) which would act as a pre-OS environment with its own high-resolution graphical user interface that sits between the BIOS and the operating system. Its due around 2006 with Longhorn and will coincide with Phoenix new BIOS changeover to Core System Software (CSS). Both EFI and CSS have the ability to enable digital rights management features.
 
Just like most new CPUs or chipsets, I'll wait until some production hardware gets tested and reviewed by several sites before banking on any kind of real performance increases from the extra cache and added instructions.
 
The locked FSB is pretty manageble when you think about it as when you buy a dell or compaq or hp intel machine you cant alter the fsb:eek: So i hope intel and amd dont go down this route or say goodbye to the overclocking:mad:

And yes this statement is sort of true?But the same could be said for the fx51 and the a64 in general You have the fx51 that is totally over priced it hasnt got an operating system that properly supports it yet need really pricey registered ram.

Then you have the 3200 that is overpriced for the amount of l2 cache it has so i think both intel and amd are on a par with there pricing at the moment no one is a winner ;)
 
One of our online vendors is offering prescotts 3.0ghz. Which will start shipping 21.01 the price is sligtly smaller than 3.0Ghz PIVC box but it's sold as oem which is really weird.

Oh did I mentioned that site is in polish:D so if you wanna take a look feel warned;)

I'm worried about that too. I don't want a S478 Prescott if they are going to stop making S478 stuff in a couple months. I bet they will make someway that you can put a S478 chip on LGA775. If they do that, it would be good, for me at least.

When are Alderwood and Grantsdale coming out? Are they coming out with the S478 Prescotts?

MHZ never had anything to do with Moore's Law. He made a statement nearly 40 years ago how the # of transistors (he explains as components) on a CPU (he explains as intergreted circuit) will double every 18 months.
It has been pretty much been revised to 2 years for awhile now and will probably hold true till at least 2008. I think thats a pretty good prediction being stated back in 1965!

Wouldnt this be a good thing? That way you get to keep your existing board. In 6 months you can sell the s478 Prescott to someone wanting to upgrade their Northwood system.
 
It could be, I'm not into selling stuff too much I don't have paypal or a VISA card yet. Anyways...

I think some of you are missing the point. You can't say that A64 3000 vs A64 3200 is the same thing as (for example) P4C 2.8ghz vs Prescott 2.8ghz. There is more that has changed in the Prescott core besides just the cache. Intel has added more instructions, and the die size has changed. The core itself will allow for WAY better overclocks than a P4C could ever hope for. Not to mention, I think the Prescott core will be significantly better then the Northwood "C" core and it will be worth the cost increase. I heard the Prescott 2.8's are going to be around $200 USD anyway, the 2.8 C's are what, $196 on Newegg last time I checked.
 
they had better be faster otherwise Intel will look silly, people are going to be asking themselves if its worth the performance increase and Intel has AMD to contend with
