i dont get the argument. faster cpus are faster?
sure they are, its not like i am arguing there is no performance increase. but the reason we dont have the performance increases we had befrore 2005, neither multi nor single threaded is not because intels greed. sure they are greedy, but they would have made more money if they could go on doubling frequency instead of cores. but they cant because of RC-delay.

while you might get twice the performance with double the cores, you are guarenteed it with double frequency. and all diminishing returns of multithreading get worse the more cores you have.

that problem was even well understood before 2005 thats why intel was ready to go multicore when they hit the 4 ghz barrier in their pentium 4s.
if you want check "The end of Dennard Scaling" "Beyond CMOS" "MOSFET"
"RC time constant"

with this technology we wont see a 100 or 1000 fold increase in performance per watt anymore. of course you can add thousends of cores but in the end you just keep using increasing amounts of power to gain decreasing amounts of acceleration.
of course something else will come, but its unclear right now what that will be.

my argument is similar to yours, I agree with "post 2005" argument in particular.
My point was, with parallelization more cores and threads were the way to go, they still are. People expecting 100% perf. jump are unrealistic, unless they mean twice more cores. In that case, HEDT is there, intel had 16/32 thread cpu long before AMD conceived Ryzen.

You guys know that there are transistors out there with way higher switching times, right?
Think 50-60GHz and beyond.
IBM made 210Ghz, see?
This one is 604Ghz and it's from 2005!
So don't come mumbling about any barrier at a measly 5Ghz.
There is a vast amount to headroom to grow into.

those are singular units, one switch, one transistor. Now put several billion of them, supply them with power, and cool them.

Besides, IBM said that they will have 100GHz operational in 2 years. that was supposed to be in 2007.

You could have said "there is quantum CPU working right now" instead.

So, you can either postpone the upgrade until nanotubes become a thing, or just upgrade already

I was going to tell Intel back in 1999 about cooling the shit out of CPUs.
They did not want to talk to me, they were "not interested" in the design.
They still struggling with heat, to date.
Fuck Intel, I hope they go bankrupt over their greed.
