So does the XP64 Run alot cooler than the 32 bit

Not sure what's normal but I can easily hit 63C when my Athlon52 3200+
is set to 1.7v in just a few minutes of gameplay.<!-- ~MESSAGE_AFTER~ -->

The core is a similar size on the P4 to that of the 32 bit Athlon.....it's
just Intel stick a metal cover over it.
The point is metal cover or no...the contact area to the core is limited by
the core size itself, sticking a metal 'heatspreader' cover over it just
makes heat transfer worse because it increased the 'junctions' that the heat
has to go through.
The main purpose of the metal cover is to protect the chip from physical
damage.

The cap (heat spreader) on a chip is likely to change soon.

o Athlon - bare die, but 4 outer pads for heatsink support
---- heatsink clamping force lower re socket-based originally
o Pentium4 - die under heatspreader for heatsink support
---- suspect higher heatsink clamping force than Athlon

The heatspreader or any cap on a die has a problem in
that it must be joined by adhesive of a finite thickness.

Some designs propose standoffs under the cap:
o A heatspreader is basically a cap
o Imagine the underside has standoffs created by machining
o Thus 5 or 9 standoffs precisely sit on the CPU die
o So the area of adhesive under those is vastly less than usual

Hence they create a lower thermal gradient in comparison to
the relatively thicker adhesive thermal compound. It uses the
basis that two flat plates only contact at 3 points. More than
9 standoffs end up back in the problem of heatsink plate.

It creates 1) fewer hotspots and 2) better thermal conductivity.

Unfortunately I see this like many recent developments as mainly
allowing more watts to be expended rather than fewer watts.

Shows how tight we are getting on density/thermal-issues re tricks.

It might already be in use - I suspect the G5 or higher PPC chips.

This is for everyone talking about this line of AMD Chips..
Of which, I know for sure that a AMD 3400+ FX53 is what I want next.
From what I know so far, the Graphic's are supposed to be as close as they
get to a Mac /and as sharp, without
Really having one.
But I really cant say before having one myself.

I don't understand that statement. The graphics/sharpness don't have
anything to do with the CPU.

Agp 64Bit running on a 32Bit cpu.
Agp 64Bit running on a 64Bit cpu, beats the heck out of me why it wouldn't
be sharper.

AGP is more direct to the CPU
It's been this way for so long, it's getting to be old school.
A high enough Overclock on the CPU, how high you have to figure out for your
self.
If you go high enough, you will have to Overclock the AGP.
You may not need a very high Overclock, (70, 71, 72, 73 MHz) this has to
be played
with a bit to find out where. And no system is the same.
This one goes with all systems, AMD & INTEL alike.
I'm studying for A+, so some of, if not all, I need to know, or get to know
if I missed anything.
If I'm wrong somewhere. (Tell me)

Because 'sharpness' (clarity) is a virtue of the video DAC on the display
card, not the AGP port.
