Quote from Vans Hardware article on the AthlonXP vs. P4;
"The current Athlon XP, also called “Palomino,” is 59% as large as Willamette, while Thoroughbred will only be about 55% as large as Northwood.
In fact, the Thoroughbred’s die size is so small that it is beginning to approach a condition known as “pad limited.” When a chip is pad limited, its die size is determined by the number of pads needed to connect the chip to its pins. Therefore, a pad limited chip is wasteful because some of its die will be empty.
Under such conditions, it is very compelling to throw more cache onto the die, or, better yet, install another core for on chip SMP (Symmetric Multi-Processing), as discussed above. AMD’s chips are evolving brilliantly towards this goal."
Now there's an interesting bit of speculation....dualies with one socket. Sounds like someone's been reading up on the HP PA-8800.
