Intel's Pentium 4 E: Prescott Arrives with Luggage

Availability, Yields and Overclocking
Intel’s 90nm fabs are working hard at cranking out Prescotts as fast as possible, but as is the case at the start of any ramp there will be supply issues. We are hearing that widespread availability of chips in the channel for people like us to order won’t be until March 1st, although you should be able to find OEMs with systems available immediately.
We are also hearing from reliable sources that the current steppings of Prescotts coming out of the fabs are performing very well. To get an idea for what sort of headroom to expect we conducted some informal overclocking tests on our Pentium 4 3.20E that we had for testing.
We conducted all tests using just air cooling and we kept the CPU voltage at its default of 1.385V:
An effortless overclock gave us 3.72GHz; we could POST at 4GHz but we didn’t want to showcase what was ultimately possible with Prescott, rather what was easily attainable without increasing voltages.
Intel could have launched Prescott at higher clock speeds than they did, however it seems that their desire to produce as many mainstream Prescotts as possible (2.80E in particular) won out in this case.
Update: Intel has released the official thermal data on Prescott:
| Thermal Design Power | |
|---|---|
Northwood (2.8 - 3.4GHz) |
69 - 89W |
Prescott (2.8 - 3.4GHz) |
89 - 103W |
As we mentioned before, if you thought Prescott was going to be cooler running you'd be wrong. Prescott is one hot running CPU, now keep in mind that these aren't actual production thermals rather Intel's guidelines to manufacturers as to what thermals they should design cooling for. Needless to say, Prescott at 2.8GHz will be about as hot as a 3.4GHz Northwood. When Intel ramps up beyond 3.6GHz we'll definitely see some larger heatsinks being used on Pentium 4 platforms; some of the preliminary cooling setups we've seen for Tejas were insane.

I can't imagine how HOT that sucker will be when up to 5ghz!!!! 150oC??? LOLFor the heat issues alone, im thinking about going AMD in my next rig.

Ace's Hardware summed it up well: Prescott is a DOG, or to be exact a HOT DOG ! See the picture in the review of the dog warming it's toes next to the Prescott powered PC. Talk about one sad CPU piece of crap...Here is the FLAME THROWER reality check:
"Currently there is no reason to upgrade to Prescott, as the gaming performance is more or less ok, but many applications report pretty poor results. On top of that, the new Intel CPU gets hot very quickly and requires a well ventilated case. The Athlon 64 3200+ is not always the clear winner in games compared to 3.2 GHz Prescott, but the 3400+ will have little trouble beating the 3.4 GHz Prescott in most benchmarks. Prescott will have to scale incredibly quickly to outperform the Athlon 64, because the latter scales excellently with clockspeed, and we definitely prefer Cool'n'Quiet over Hot'n Prescott! "
As shown this FLAME THROWER don't scale well, especially when it runs 15-20C hotter than an equal speed Northwood. Intel really fugged up this time. Ya gotta love seeing the Satan eat shit and choke! When every hardware review site on the planet, including THG's tells ya Prescott is a piece of crap, then you might as well resign to reality. DENIAL is futile!
Dell will be selling FLAME THROWING PC Heaters to any gullible sheep foolish enough to buy a Prescott. A fool and his money are soon parted !

"Ummmm yea, kinda reminds me of cooking an egg on an Athlon XP"Yeah, kinda, except the Prescott can do the same work in about half the time. Sounds like something they should advertise that as a feature...

What happened to CRAM's post???INTC - Monday, February 2, 2004 - link
#43 cliffa3 - http://www.x86-secret.com/articles/cpu/prescott/p4...It doesn't look good for P4G8X with either the 2.8/533 or the 800 MHz FSB flavors.

For those who missed it, X-bit gave a temperature comparison, for the all the chip.http://www.xbitlabs.com/articles/cpu/display/presc...
Processor; Idle, Burn
Pentium 4 (Prescott) 3.2GHz; 45oC, 61oC
Pentium 4 (Northwood) 3.2GHz; 30oC, 48oC
Pentium 4 Extreme Edition 3.2GHz; 32oC, 51oC
This does not bode well for Intel unless they are going to make water cooling a standard.
But this Quote sums it up nicely IMHO “I am scared to imagine what happens to Prescott when we close the system case…”

what??? no talk about heat on this chip? Come on anand this is vital info about prescott. Other sites are reporting temps up around 80c with the stock cooler. I understand that as it gets faster in mhz it will be a better performing chip but what kinda heat are we looking at at 4ghz? No way is a 80c chip going in any of my boxes. If keeping an intel badge on the front of my case means i have to have a delta fan in my box then you can forget about it.Stlr22 - Monday, February 2, 2004 - link

Stlr22 ....Re post # 31 Hahahahahahahahahahahahahahahahahahahahahaaha!!!!That one had me cracking up for 5 minutes!
It is good to laugh!!! :-)
