New retail PIII looks like a P4??? What's the deal?

[Butros]

I just recieved a new shipment of Intel PIII (133 Mhz Bus) Retail Box CPU's, and when installing them I noticed something strange... the actual core is not the blue small square I am used to, instead it is a big silver metal core with the little hole in the corner (just like the P4 core).

Does anyone know anything about this? Would these babies be better for O/C'ing, should I keep 'em for myself and order more? What's the deal?

Those are probably the Tualitin P3s. They have larger slugs so as to make it harder to crack the core, and to dissipate the heat easily over a wider area than the small blue ones. Very smart move IMO. If I wasn't so budget-minded, I'd get one myself.

edit- also make sure you have motherboards that support Tualitins (are they called P3-M or something like that?), cause they don't work on the motherboards meant for the FC-PGA Coppermines. However, the FC-PGA Coppermines will work on motherboards meant for Tualitins.

You sure that's not the heat spreader.

Is that what it actually is? Is the tiny .13u core under a "heat spreader"? Whatever it is, I wish AMD would implement it too

 

[Athlon4all]

I too wish AMD would 2 go to .13um+Heat Spreader.

It is running fine in a Shuttle AV18e motherboard. I'm not sure what it is, the last shipment of 1 Ghz PIII's had the blue core, I get a new shipment the other day and it has a big silver metal core similar to the P4. I initially thought it was just a heat spreader/protection for the core, but then I started thinking about it and was wondering if this will help or hinder the O/C'ing of these CPU's (I know 1Ghz aren't the best subjects anyhow).

The heat sink is not touching the core directly so I was wondering if this will limit them further, or actually be better? I was unaware of this change to the PIII line, and I was just looking for any info I can get on it.

Thx,

if properly assembled in a tight sandwhich (core/paste/spreader/arctic silver/heatsink), it should work just fine, and it is a good way to prevent cracked cores.

Does .13 micron PIII's(Tualatin) comes in 1Ghz? Last time I read about Tualatin, the desktop version are >1Ghz. Could this be a "CDO" stepping of .18u PIIIs? I lost interest in PIII long time ago. With all this talk about Athlon 4, and P4 ( especially the P4 with SMT)...droooool?

I'm just as confused as you are. I read that Tualitins were only to be made at 1.13GHz and 1.2GHz. I'd like to get my hands on a Coppermine with the heat spreader, could make for an overclock into Tually's region :Q

It's a heat spreader. The Tualatin's are available @ 1.13GHz and 1.2GHz w/256K L2.
They are also available at 1.13GHz and 1.26GHz w/512K L2.

There are 1GHz Copperine variants with the Heatspreader @ 1GHz.

I wouldnt bet on it.
Though the cD0 stepping commonly manages 1.1-1.2GHz.
My own cD0 866 does 1157MHz.

The 1Ghz P3 with a heat spreader is the Coppermine-T.

Yes, but but besides the heat spreader it is identical to the classic Coppermine.
Contrary to popular rumours, the Coppermine-T is not .13umicron nor is it a .18u Tualatin.

 

[Wingznut]

As far as I know, there's no such thing as a CuMine-T. I know it garnered some rumors on the 'net, but I've never heard of such a thing at work.

There is definitely no such thing as a .13um Coppermine or a .18um Tualatin.

So, I'm really not sure what a Cumine-T is supposed to be.

 

[DClark]

The Coppermine-T is just a normal Coppermine with a Heat Spreader on top.

The "SL5FQ" 1Ghz processor in this link is a Coppermine-T. Using the numerical specs on the far right column, the Coppermine-T:
-This processor is a die shrink to .18 micron process technology
-This processor's system bus operates at 133 MHz only
-Vcc Core Voltage - 1.75 V
-This processor is in the FC-PGA2 form factor with an Integrated Heat Spreader.

It also uses cD0 stepping, 256kb of level 2 cache, and uses the same CPUID as the 1Ghz D-stepped P3 without the heat spreader.

I would have mentioned this in my first post, but I figured that most people knew that a Coppermine-T is not a Tualatin.

Definitely not a safe assumption, I've seen some pretty wild claims regarding it.
