price -vs- POWER 4 (with apologies for mammoth posts)
Quoting PC_Convert?:
The POWER4 series are used in IBM's top servers, these things are amazing.
POWER4 is v.nice but way too expensive.
This, unfortunately for us, is true <damn>. However, ther are a few reasons to keep it in the range of hopes and Christmas lists:
#1.) As you said, pc_convert? (can we call you Mr. _convert?..? ;-> j/k), the POWER 4 chip is being assigned to a number of IBM's top end servers. However, the G4 has been used in a number of other servers and Apple got a version of
it; specifically, the A-6000 was listed, at one time, as running the G4 processor. Obviously, the difference between the logic board for it -vs- a Power Mac is like comparing a Stealth Bomber -vs- a Volkswagen GTI. But, that
could hint at something. IBM/Motorola made more money, on the G4, once they started allowing sales of it by companies operating outside of the markets they, themselves, were aiming for. And in having done so, Apple got a much needed "big dog" processor while the Linux community gained a new best friend in
brute force processing ,
Total Impact. If IBM, truly, wants to increase the speed of their return profits on the POWER 4, they had
better consider a vendor from a market that doesn't directly compete with them. And, Apple is about as far away from competing with them as anyone is ever going to be.
#2.)Basic macro-economics! The more attainable the product, the greater the popularity; the greater the popularity, the greater the demand; the greater the demand, the greater the profits. Emphasis on the word "attainable", here. This is to imply, both, reasonable price and adequate supply. No matter what, IBM is going to
have look at the cost of having developed that lovely little demon and figure the fastest way to make their money back on it. If they keep it in their premium machines, and nowhere else, it won't make them any money for at least a year and a half.
#3.)A possible POWER 2! One of the links pc_convert kindly provided us with (thank you, of course) noted the possibility of scaling the design of the POWER 4 processor down to a 4 core system as opposed to the bombastic 8 that it's sporting, now. Here's what it said:
Perhaps the best part of IBM's design for the POWER4 is its Multi-Chip Module (MCM). This novel packaging technique carries four chips, each with two processor cores, which makes for highly efficient 8-way SMP systems. Not only does IBM stand to dominate the high-end server market with these 8-way SMP monsters, but also it would be even easier, hypothetically, to create "scaled down" versions with two or four processor cores.
My reason for pointing this out is that it's been a consistent component of every
reputable Macintosh rumor site's speculation that the next generation Power Mac is due to have an optional 2 or 4 core mother board and will hum along at about 2.? GHz. The POWER 4 already runs from 1.8 - 2.4 GHz... Hmmm. Considering the POWER 4 is a series of 4 chips wth 2 cores each, then, what about halving or quartering the core count [like the article said] into a simpler version of the same thing? One might be able to do it in the same factory, even. Each chip in the POWER 4 is supposed to be 64 bits. Granted, that would be dropping by 50%, in terms of bit depth, from the G4. But, you're gaining greater performance with the quad 64s in a single die, than, two separate 128s. This would also solve several current design/manufacturing hurdles for Apple. One socket size (for all mother boards) and one CPU type with variable core counts as opposed to two socket sizes and two very different CPUs. No scorching hot Velovity Engine to contend with either.
