Random question about cpu

EPPHO · July 12, 2016

So my question is: should old cpus (like ones on 775 socket) be more warm than new ones or is it number of cores which makes cpu warmer? Or is it all about architecture?

Architecture. Depends on many things. Mostly TDP.

im no EXPERT, but i would give my thought.

the heat produced by cpu is mostly cause of voltage applied to the cpu. that causes it to heat up. also the number of physical cores makes it even more widespread on cpu. i.e, more voltage has to be used to power more cores.

also the architecture should be a big factor in this. modern cpus have complex micro structure resulting in more thermal out put.

(pls some one correct me its a very good question btw, i also thought about it before)

i have old cpu, it is intel pentium dual core e6500 and today i cleaned the cooler and obviously changed thermal paste. So i am wondering is 59 degrees celsius under full load for 10 minutes good enough with stock cooler? I wonder because i bought some little bit cheaper thermal paste and now i wonder would it be good enough if i put it on some skylake cpu...

Check the TDPs of both chips.

There's a lot that goes into this. Yes, in theory, newer CPUs are built using more and more efficient architectures which could make them run a lot cooler. But they're also getting smaller, not just in terms of die area but also an increasing number of transistors packed into tighter spaces. Some features that were (at least in some architectures) part of the chipset have been relocated to the CPU die itself. All of that can affect heat generation as well.
