Can you you expand your thoughts regarding these sentences? Adjustments that impart sub-cooling attributes sounds pretty neat.
Also elaborate where, if any, the things that AMD
could do in your view cannot be done by Intel as well.
I'm a tad baffled by the P4 comment. What wasn't scaling despite its awesome mhz? I thought everything did scale, and that was the problem because power consumption scaled right along with everything else.
(BTW you'll note these 125W TDP chips from both companies are approximately as power hungry as those unacceptably power-hungry preschotts of 2005)
We have seen over the course of a year AMD doing subtle tweaks to the Phenom platform to get where we are. There are still plenty of areas AMD can go into to sqeeze more oomph out of the Phenom line.
More efficient metal gate technology, they were going to do what Intel does in the i7 but it was too early and probably cost too much at .65nm and money tight AMD of 2008 couldn't do it for the .45 PII. Phenom can be transitioned to this at .45 if they can be that elastic of a company in late 2009/early 2010.
Cache latency is still pretty high compared to i7. This can be addressed on a new core revision.
Now I am not saying its going to hit 5ghz on air as it would on LHe, with ease I might add, but it can probably churn 4.2ghz on air and low voltage with some more tweaks to the platform. Surely those tweaks would make it more than comparable to the high end 1400 dollar Core 2 HardOCP pitted it against but we 'might' see it start being comparable to i7's.
And no, the P4's performance didn't truely scale as well as as every other part of it, like heat, did. The numbers of the PII at 6.1ghz screenshotted in the link are more than double the numbers of the PII at 3.0ghz.
Can Intel do the improvements AMD can do with the Phenom line? Isn't that exactly what the i7 is to the Core 2 I would ask. Intel will most likely do enhancements to the chip that are more on line with what they will have to do with the .32 process when they go .32nm. Nehalem is pretty optimized from the get go, classic Intel post Core 2. AMD haven't had that luxury being on the ropes for over a year. Will the AM3 sans DDRII IMT have more evolutionary changes to it? Time will tell.
