Which CPU run Hotter EE or Prescott

[Mir96TA]

Which CPU dispade more heat under same load with Same MHZ

Prescott is just the name of a core revision of the P4.

Some P4 EEs are Prescotts.

So P4 EE suppose to be Gallatin core; which them Makes Prescott same as Gallatin ?
I thought Gallatin core is Xeon Base
So Prescott Core and Gallatin core are same thing

 

[A554SS1N]

If both are P4, then they will most likely both have similar thermal characteristics.

 

[Auric]

Thermal Design Power: The maximum amount of heat which a thermal solution must be able to dissipate from the processor so that the processor will operate under normal operating conditions.

3.4EE Gallatin: 102.9W

3.4E Prescott: 89W

Some Pentium 4 EE processors are Gallatin, and some are Prescott. It would help if you could identify the actual models you are talking about.

And you'd better be getting a great price if you're even considering one of the Extreme Edition parts.

I can get the CPU for $120
Shipped to me for $130
Simple Chip swap.......

PEE I am talking about is
Intel Pentium 4 Extreme Edition
Clock Speed 3.4GHz
FSB 800MHz
L2=51K
L3 2MB
SOcket S478 CPU
========
I need to find out How much I can sell my Prescott 3Gig for With non User Intel HSF (Retail Box)

 

[Auric]

S478 was assumed otherwise with S775 there would be little reason to consider an EE with completely disparate pricing. Such later Prescott are definitively better than the previous Gallatin as well since they have equivalent cache plus all the added features.

3.0E sell for about $70 new OEM. The retail HSF isn't worth much and the more important factors for a buyer would be revision and warranty. Check past transactions on eBay.

i *have* a 3.4EE ... the Gallatin core is a Northwood via Xeon with the 2MB of added L3 cache

i know the Prescotts [1MB L2cache vs the NW's 512KB] run hotter than the NWs

my P4EE 3.4Ghz runs in the 50s [80F "room temeperature"] up to the low/mid-60s under extreme load and O/C'd to 3.71Ghz [1.55v Vcore]
[using an all copper - cheapie - TT "prescott" cooler -TR2-M12]

 

[Stumps]

P4EE's based on the Gallatin core tend to run cooler than those that are a variant of the Prescott...much like the Northwood P4's run cooler than the Prescott based P4's.

Gallatin's run barely warmer than Northwoods at the same clockspeed.

in the Thermal Specification, the Gallatin at 67C is 2.1 degrees less than the Prescott ...

now could someone please *translate* the following"

Thermal Specification: The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor?s automatic mode is used to indicate that the maximum TJ has been reached.

huh?
[is it talking about a maximum temp where CPU 'throttling' occurs?]

--and it looks like i have been *under-volting* my EE :Q


1.575v ... quite a bit more than the Prescotts and more than my last 2.80c [NW]

:Q

i always found it strange that the Prescotts are on a smaller process [90 nm] than NW's 0.13 micron and yet run hotter at the same clock ...
--with even less efficiency

i guess that was intel, '05

Leakage was the culprit for that I believe.

i don't think so

leakage may have been the reason for the extreme heat initially [and melted MBs from the first few Prescotts] .... but intel never bothered to 'fix' it completely, i guess

there seemed to be more than that ... the reason intel just *dumped* P4 and NetBurst in the trash and fell back on Plan B ... further development of the M which was an extension the P3 architecture ... and finally conroe and onward

i thought it had to do more with increasing pipelines and the near impossibility of prediction and debugging that stopped intel dead in its "10 Ghz P4" plans
