Does More Cores Mean More Heat

[tranzitbusbeast]

Lets say you have 2 AMD 8350's side by side. One CPU with 8 Cores and another with 4 Cores, and each core in both CPU is running at the same voltage and clock-speed; Which CPU will get hotter faster and which cpu will have a higher max temp presuming the cooler is the same on each CPU.

Seeing as the 8350 only comes in an 8 core version:

That comparison cannot be made.

In the spirit of what you are asking, I think that the proc with more cores enabled will still get hotter than the one without all cores, same clock. On an abstract of that though, it would also be a function of utilization within the loading program.

the 8700K runs a bit warmer than the 7700K, so,....

Yes,

more cores at similar clock speeds w/ similar core voltage inputs on same basic die /manufacturing process equals more heat.....

In AMD FX series all cores get power all the time as they are not physically disconnected. FX 4350, 6350 and 8350 are actually all same except some cores are disabled from normal use but still get power.
One can say that all of those processors start as FX 8350 but in production some cores may not meet standards and are disabled giving us anything between 4300 and 8350 with 8370 being better binned 8350. Only under full load disabled cores receive and use less power but that's very small percentage of total power so it doesn't help much in terms of power and heat.
