We have first gotten our hands on the LGA 775 Prescott/Tejas back in June and many people are curious how it looks like inside when the IHS is removed. The procedure of removing the IHS is similar to the current Pentium 4 as you would need a thin blade to slice through the rubber padding nicely and slowly.

We have first gotten our hands on the LGA 775
Prescott/Tejas back in June and many people are curious how it looks like inside
when the IHS is removed. The procedure of removing the IHS is similar to the
current Pentium 4 as you would need a thin blade to slice through the rubber
padding nicely and slowly. Though the usual procedure of removing the IHS from the P4
processor is easy but it is not the case for this LGA 775 Prescott. We find that
the die is firmly adhered to the IHS making it hard to remove as there is some
sort of solder-like thermal interface in between the surface of the die and the IHS. There are cases being reported where
even the newer batches of P4 processors use
this type of solder-like thermal interface too. Therefore those who like to rip
off their IHS for more efficient cooling will not be able to do so now.

For curiosity sake, we continue to rip out the
IHS to check out the inside and of course the die came off along with the IHS if
you do that.
There are some changes to the design of the IHS as the underneath is covered
with a layer of copper for faster heat spreading unlike the one on a P4. (Check
out the pics below)

It is always interesting to check
out the die size of the
Prescott and it works out to be approximately 110mm2. Prescott is
touted to have packed with 125M transistors on 90nm process technology so the
size of the die is pretty in line. In comparison, the current P4 Northwood with 512KB of
L2 cache has about 55M transistors. The more than doubling of transistors comes from
increase of caches (L1 and L2), enhanced HT with 13 new PNI, La Grande security
technology and possibly the 64-bit instruction set support. Other interesting
information on the Prescott is that it has 7 layers copper interconnect, Low-K
and on Strained Silicon.
