Another sign that CMOS industry has hit the clockspeed wall.

Intel Tejas and Jayhawk have been canned and replaced by Jonah based device instead. Intel's transition from 3.6 Ghz Pentium4 to 2 Ghz P6 architecture is sooner than expected.

With the death of Pentium4, the CPU industry is stuck in the 2~2.5 Ghz range for a while, this includes both CELL and XCPU2...

I read somewhere that R420 burns 76 watts, nV40 a lot more(100 watts???)

Average Power Consumption under load - 65 - 76 Watts quoted*
*Average power draw while looping 3DMark 2001 and 2003

This power consumption thing is out of control, Xbox Next and CELL are going to burn 200 watts and double as room heaters...

R420 uses less power than r360.

nVidia documentation claims a maximum of 110 watts for nv40.
 
You don't need high mhz or new tech for that though.

I used my Spectrum48 as a room heater all the time.
Amiga worked pretty well as one too when you put it on a soft surface that prevented heat from dissipating normally.

My points exactly, nVIDIA was forced to lower nV40 clockspeed to keep its power consumption under control.

Now, imagine CELL with its Power4 core and 8 APUs clocking at 2 Ghz, sucking up power like the world has never seen before....

I didn´t know that Cell cores are based on the Power4 core, any source to that?

Intel has struggled alot with it´s 90nm tech but that is in my opinion more a result of bad implention of their process.

We will see for certain if it´s a "trend" when AMD get´s out their 90nm CPU´s, but this far they seem to have a pretty solid 90nm process going on.
 
Clockspeed is really his last argument about Broadband Engine, seeing as how everything else has fallen through.

That and programming, which won't be known for another 18 months.
 
Programmability is the only argument one would need against an architecture, assuming legitimate concerns.
 
Remember Pentium III was stuck at 1Ghz for quite a while...It is about time that Intel needs fresh new architecture. I don't think it is problem with CMOS process itself..but problem with P4 architecture..it just doesn't scale up anymore..
 
When IBM's CTO says CMOS is dead it's good enough for me. That said, the industry has found a way to innovate when needed in the past so there's no reason to think they can't going forward.
