PIII 450 or PIII 600 consume more power?

I've just received a slot 1 PIII 650 CPU. Before i replace the PIII
450, i want to know whether PIII 650 will put more stress on the
motherboard. I know PIII 650 is obsolete now , but i only use my PC for
surfing the net.

Question: which one consume more power?PIII 450 or PIII
650(coppermine)?
Will PIII 650 put more stress on the motherboard?

What voltage is the P3/650?

The specifications published by Intel include power requirements. I'm sure
the specs for PIII chips are no longer on the Intel website but googling
would probably come up with it.

Don't be so sure about them no longer being on Intel's website, Intel
keeps very good documentation. You can find the processor power
consumption through the following page:

http://processorfinder.intel.com/scripts/default.asp?

Just select the Pentium III processor line and find the sSpec of the
processors.

FWIW a PIII "Katmai" 450MHz consumes 25.3W of power at 2.0V. A PIII
"Coppermine" 650MHz chip consumes 17.0W at 1.7V. The 650MHz chip
should actually be putting less "stress" on the motherboard than the
450MHz chip, not more.

Hios PIII 650 is slot one. Did the Coppermine come in a slot package?

Yes. For some of the P3 models, they had both Coppermine ( < 2V) and Katmai
(2V) models at the given speeds, but for the 650mhz and above.

650mhz - 1ghz Slot 1 processors were available. I don't think they ever did
Slot 1 processors over 1ghz, but I may be mistaken (and the later S370 ones
up to 1.4ghz could be used in some Slot 1 boards with the right adapter.)

Yes, up to about 1 GHz as I recall. I think they were all 100 MHz FSB,
as the 133 MHz bus required the 810 or 815 chip set and was usually
used with Socket 370. I had a Pentium III 800 MHz Coppermine in a Slot
1 package (100 MHz FSB) some years back.

Slot 1 processors were made with both the 100mhz and 133mhz FSB.
Depending on what you mean by stress ? If you are worried about the
physical strain , stop worrying. The major thing to worry about is
making sure the motherboard you have has a BIOS that recognises and
supports
the 650mhz chip. Many slot 1 boards did not support much more than
450mhz. The Intel 440 BX boards were popular for the slightly faster
chips.By the way the slot one chip has twice the L2 cache of it’s 370
socket son and many thought it took a while for the faster 370 socket
chips to arrive before there was any benefit at all.
If you can find a slot 1 board to support the 1G slot 1 processor is
the challenge..the 1G slot one were more common in servers etc.
Anyway often there are BIOS updates for early boards to help with them
supporting the 650mhz...

The 650/Coppermine will need lower voltages from the motherboard,
which it MAY or MAY NOT be able to provide (early and/or cheap
motherboards couldn't handle this). It'll use both less power and
amps, so it should be easier on the MB IF it supports 1.65V (for
PIII-650, Slot 1)...

In addition to this the motherboard might need a new BIOS, which may
not be available, though *usually* it will only look weird and protest
a bit during BIOS startup...

The bus-speed must also be supported, but both P-III 450 and 650 was
only available as 100 MHz versions, so that one isn't a problem.


Voltage is the big question here, I don't think I've ever seen a
voltage-converters for slot 1 -> slot 1 (many socket 370 adapters for
slot 1 motherboard had them, but that doesn't help you).

From the spec it looks like the CPU MIGHT be able to run on the
PIII-450's 2.0V (abs max core voltage 2.1V), but it certainly would
stress things considerably. I've never had any luck running Coppermine
processor on motherboards that didn't provide the ~1.7V they want, so
I doubt it's a practical solution

Since you didn't mention what motherboard you're using we can't help
you to check if it's compatible, but it's usually possible to find out
by digging on the manufacturers website.

Most non-overclocker boards will simply refuse to power up if the
processor's VID is one the board doesn't support.

Most BX-based OC boards even from way back when will support to lower (and
higher) voltages... I'm pretty sure the early Abit BH6 revs predated any
P-IIIs, Coppermine or not, and yet mine ran fine with a P3/800mhz.
