watercool gernal = overclocking. With it overclock by the user or the factor (with factor warrentis) it is still just an overclock G5. Show me a G5 that is not water cooled running at 2.5 Ghz. The 2.5 ghz is just pretty much an overclock G5. There is a reason it FSB speed is higher. take the front side bus x the chip mulitplier and you get clock speed. BTw the fee bus speed is something a lot less that 1.25 Ghz but there is a muliplier on the bus speed as well. the real speed is some closer to 200 mhz.
And btw the apple clock speed is higher than AMDs they past up AMD this year but yet AMD can still keep pass to out run them (just like they are doing to intel even though intel has a 3.4 ghz chip)
Um... you are so wrong. I suggest a spell checker as well before you post to make your post seem intelligible.
The 2.5GHz G5s, and the older 2.0GHz G5s are different. If you were able to remove the watercooled heatsink and the aircooled heatsink, you would be able to tell the difference. The difference being that the 2.5GHz would have a small die than the older 2.0GHz.
Okay, boys and girls, what do you get if you have a 1 square inch chip that is using 100Watts and you shrink the chip down to 1/2 square inch without reducing the power? If you retain the same cooling solution, you end up with a heat-stressed/dead chip, because you were not able to get the heat out as fast. Its kind of like a piece of metal pressing down on your skin with 1 pound of force. In the first case, the piece of metal touching your skin is a square inch in area, everything is fine. In the second case, the piece of metal touching your skin is 0.0001 of a square inch, you just got poked with a needle.
The bus speed increase also helps in the performance of the 2.5GHz, but as indicated in prior posts, its not a scaled increase. That means that something else is the bottleneck now. It could be I/O speed, it could be latency, it could be a whole lot of other things.
