prescott

[borntosoul]

hey all i thought id just delve into this for a tic since we got these chips just around the corner, personaly i think intel will be hard to stop and the prescott with the springdale chipset looks cool .
here is the link but ill paste most of it here

Summary:
"In the keynote speech from Louis Burns today, we found about 13 new instructions that will be added to Prescott. This isn't all we found out about Prescott - many of the blanks were filled in on what we can expect from it."

Prescott Paves The Way For Tejas

"Louis Burns is the Vice President and General Manager of the Desktop Platform group at Intel. Today he gave us the low down on Prescott. From our attendance at previous IDF events we knew little more than the code name Prescott and the fact that this processor would be built on the 90nm process. In our experience, the keynote addresses from Louis at previous IDF events have been some of the most important highlights of the events."


"Louis Burns gets the ball rolling with his look at the platform solutions."

"After this keynote, the talk of the day was the news about the new next-generation processor from Intel codenamed "Prescott." The Prescott processor will be developed on 300mm wafers using the 90nm process. The Prescott will feature the use of sub-100nm strained silicon technology and include seven layers of low-K metal interconnects."

"In addition to the process changes, Intel will be adding additional enhancements to the NetBurst Microarchitecture as well as to the HyperThreading (HT) technology that is already available for the Pentium 4. Since power continues to be an important issue, Intel will add additional Advanced Power Management support to the Prescott processors."

"The Prescott will include a larger, 16KB L1 cache, which is up from the 8K included in the Willamette and Northwood cores. The Prescott will feature an 800MHz front side bus and an incredible 1MB L2 cache. These additions will make up the over 100 million transistors that will make up the Prescott."

"The processor itself will feature 13 new instructions that will be added to the base instruction set. Two of these will feature instructions specific to improving the performance of the HyperThreading technology that is found in Prescott. The other instructions include FP to Integer conversions, Complex arithmetic, video encoding, SIMD FP using AOS format, and Thread Synchronization. The majority of the rest of these instructions are targeted at media and gaming applications."

"A great deal of emphasis was placed on the new improved pre-fetching algorithm that will be contained with in the Prescott score, which should help avoid very costly pipeline stalls and enhance the performance of Prescott as well."

"Okay, now for the big answer that you have been waiting for... the Prescott should scale to the 4GHz-5.5GHz range until it is replaced by Tejas. Tejas should feature at least 1.2GHz FSB. Yes, that's right, a 1.2GHz front side bus - but that is all we know about it at the moment. Springdale and Canterwood (865 and 875) will be the chipsets for the Prescott, as you most likely know by now."



this cpu should rock !

[tazdevl]

Yup, that's what I'm holding out for before I upgrade.

Not to mention we should be seeing it end of Q2 early Q3, 90nm and a lot of OC'ing potential.

It'd be nice if we saw a hammer around the same time, but no such luck. It's gotten some intersting press lately.

OMFG 1mb L2

dude, screw my p4 im gettin that.

[borntosoul]

yeh it really looks good to me and those 13 new intructions should be even better than the sse2

[silence]

me waiting for hammer.......also 1mb L2.

what you all think,which one will be better?

[borntosoul]

i think the prescott will be hard to beat . they had all that time to fix what was weak on the p4 ! ht will be better used this time round ,new intructions and .90nm ,i cant see hammer keeping up until maybe half way past 2004

programs still won't be optimized for HT this year. HT is definitely a non-factor except with multi-tasking, where it does show some benefits.

the main benefit of Prescott is that it will be stronger than Northwood clock for clock thanks to its increased FSB and cache. although i wonder how much improvement the 1MB cache will provide. i do have to credit Intel, it's cache is very efficient, better implementation than what AMD has with Athlon.

[borntosoul]

ht will be much improved with the prescott ,and from what ive read ht on the p4 was just the start of it all, there will be heaps headroom with this new chip . HT is definitely a non-factor except with multi-tasking, where it does show some benefits. you might be surprised hehe :)

Depends on what i can affoard.

If i can affoard a Quad Hammer setup, ill go witht he hammer. OOOOO Quad :D

If i cant, and i doubt I will, ill go Intel, because it will be faster on games.


You cant deny the Quad Hammer's they are so 1337.

[tazdevl]

Only problem is that to truly get things rolling with the hammer you need 64bit optimized apps and drivers. There's going to be a lag, kind of like when Win2K came out.

[ReDeeMeR]

I'll just buy wich one is gonna be more preformance/price efficient.

people were saying that HT would surprise us when it was introduced into the consumer space on Northwood. keep in mind HT existed already on Xeons.

i still stand by my original expectation, software needs to be optimized to take advantage of HT, just like software had to be optimized to get any type of good performance with P4s. it's the same old story.

maybe i'm wrong, and maybe software will start being optimized for HT this year. but i still don't believe that Prescott's HT will improve my current software experience when single tasking.

HT is more marketing than anything else. i mean honestly. how many people need to encode audio or video while they play games. would it be nice to be able to do it? yeah. is it will necessary or practical? no.

[GlowStick]

WEll, i dbout stuff will ever be optmized for HT. because SMP has been around forever.

But if they do start makeing program multithreaded, then the cheeper Dualie AMD systems will rip all over the single p4's.

As demonstrated with Windows XP SP1, Adobe Photoshop with their SMP patch for Xeons EG 4 logical processors.

That was shown in a Quad Operton system ;D

[StealthHawk]

SMP is not mainstream, which is one reason it's not optimized. not many consumers own SMP systems, but with all new P4s having HT capability, things could change. it will be a good move forward for the whole industry.

of course there are almost no HT capable CPUs out on the market right now, only the most expensive P4 has it. which is one reason i don't see industry acceptance for at least a year after more CPUs with HT get released to the public.

Another reason why most programs arent SMP enabled is because unless they are constantly useing 100% of the processor they arent 'power hungry'

Such as, my email client, it dosent use 100% of the time so if it was smp it woudlnt do didely squad.

So not all programs need to be smp enabled, only things like MP3 encoders etc... and all development software. witch most of it is.

obviously when we are playing games we wont be multi tasking but have a read of this and tell me what you think
http://www6.tomshardware.com/cpu/20021227/index.html
and
http://www6.tomshardware.com/game/20021228/index.html
this is from THG "In real world situations the feel of Hyper-Threading is much better that our benchmarks actually show; this is why we also produced the video, which demonstrates this. Hyper-Threading is particularly beneficial when at least two applications are making heavy demands on the processor simultaneously. This can easily occur when you are archiving large amounts of data in the background, while working with your standard office applications in the foreground. Similarly, MPEG-4 encoding of a DVD film can be carried out, while at the same time e-mails can be edited with several browser windows open. One important conclusion for all hardware test magazines is that everyone must re-think test methodologies. Running just a single-threaded benchmark on its own does not represent real-world behavior anymore. THG has started working on this issue already, and our video gives you a little taste of what's to come."

i still think if its programed right there could be as much as 20% , remember what they said about sse2 look how much that has improved the performance of the p4 . im not saying that ht will make a huge difference by it self but it will be just one of many features that will make a lot of difference

i like to use win mx for d/l music and playing it through my computer ,playing sim city while i got that in the back ground HT would help i think thats just one example

[StealthHawk]

i listen to mp3s while playing games sometimes and notice no slowdown.

[borntosoul]

you got the same cpu as me too ,it might be my ram ,+ my video card sucks :(

As dualie enthusiast, dont go for SMT, go for the full thing SMP!

Yes you can do all those but better with 2 cpus.

WHy dont ya guys take a Gander at http://www.2cpu.com for more info, rember, you can never have too many CPU's

muhahahahahaha

[borntosoul]

too much money to run a duel system ! sorry im not that power hungry

muhahahahahaha Of course you could do "better" with a dual CPU system over a HT'ed one, but one is almost no more expensive than a single processor system, and one would be WAY more expensive for the same CPU speed, or drastically reduced CPU speed to keep the price competitive. A HT'ed processor system gives you a lot of the benefits of a true dual CPU system for almost no extra money.

Maybe in the future, but right now u can build an Athalon MP system cheeper than a 3.06ghz p4...........

Infact my 2x 1.4 athlon MP system was cheepr than my 2.53ghz p4 sytem i have now :O

[Dazz]

Me i have gone off Intel due to them keep on changing their socket layout :mad: but i will be looking into either a Presott or a Athlon 64 as either way i would need to upgrade my board & HSF memory etc lol :( Prescott is now a Socket T processor, so if you have an current board it won't work, i belive it has something like 7xx pins.
