Processor Heat Spreaders - OLD

Correct my if i am wrong and this isnt an issue or anything but whats the big deal with them (and related to P4)? in the Semperon 3400+ article they mention the P4 as the first to use it (as in "Like a P4" ) - correct me if im wrong but dont Pentium MMX's (~1995!!!!), Pentium 2's, Celerons, and the later tualatin P3/celerons all use them (all Bar Coppermine Intels)? and as for AMD - the K6, K6-2 and 3 aswell - why do all articles say P4 used them first?

im just really sus cause its such an old thing now but yeah - maybe THG is trying to make intel look good.

all coppermines/180nm versions never had em but ALL tualatin/130nm did - perhaps cause the die was alot smaller, the coppermines were the first from intel not to use em as a desktop variant.

i stand corrected

and yeah - cyrix too

but THG and heaps of other sites always mention P4 as the first to use em - blah, anyhow...

the anual THG cpu charts have pics of them all:

This page says it all - the K6(2) and Pentium MMX processors both with heatspreader designs well before the Pentium 4, and even these cpu's wernt the first, looking back to the previous pages and pics of the first pentium 1's and the K5 both with the classic Gold HS.

Followed by the intel celeron / pentium 2 for slot 1 both with HS

take note the coppermine cpu with integrated cache on die - the coppermines were just about the only series without heatspreaders (and as crashman pointed out the later ones even did)

mendocino and coppermine processors AND THEY EVEN MENTION THE HEAT SPREADER (see the bottom)

AND FINALLY THE P3 TUALATIN WITH THE P4 STYLE HS:
