3600x tdp question

[alxne]

The 3600 TDP is 65, but the 3600x TDP is 95. I've been reading that the only thing that makes the TDP 95 is the cooler it comes with. So if I replace the cooler with something else, what is the TDP of the 3600x does it remain the same or is it lower?

Remains the same.

TDP has nothing to do with the cooler. You can change your cooler but it will remain the same.

The TDP of the 3600x is always 95W 

( unless you undervolt it )

same, does not change by changing  the cooler.

The TDP is a design value use to scale cooling. As long as you use something no worse than the given TDP, you will get at least the minimum performance from the CPU. A better cooler than minimally required can allow it to boost higher/longer than with the stock cooler.

 

Also note TDP is NOT maximum power consumption. From memory on Zen 2, 65W TDP CPUs actually have a limit of 88W (PPT) at stock. I don't recall the values for higher TDP CPUs, but again it is higher than the TDP value.

TDP of a CPU and TDP of a cooler have no relation whatsoever. There's no industry standard for measuring TDP, so everyone does it differently. For AMD it's mostly a measure of power consumption while boosting (though it's still arbitrary) and for Intel, it's mostly a measure of running at the base clock (though it's still arbitrary). This is why you'll actually find AMD CPUs with higher TDPs than Intel CPUs running both cooler and with less power than those Intel CPUs.

 

When it comes to cooler manufacturers, it's even more arbitrary, especially if they're selling a cooler for both Intel and AMD CPUs. In general, you just buy a cooler with a TDP higher than your chip, and that should be good enough.

 

Mostly about AMD, but same principles apply to Intel.

While there may be differences in their respective TDP definitions, I don't think that is the main factor that Intel CPUs can run higher power (but not necessarily hotter). The big difference is that Intel do not enforce a power limit when CPUs are running non-overclocked. Unlimited power budget is not an overclock, and an allowable "stock" condition. AMD however do enforce a power limit on Zen 2, known as PPT. This is 88W for 65W TDP CPUs. So at stock operating condition, Zen 2 CPUs will have a power limit. To remove that power limit is considered overclocking by AMD.

Very untrue.

 

The Thermal  design point is all about cooler selection.

 

Generally the stock cooler covers the cpu TDP and nothing more = no overclock head room.

cpu tdp is kinda meaningless marketing jargon, 3600 actual power draw is closer to 95w, the 95w tdp cpus are closer to 130w

 

The tdp rating for coolers are a better indication of how much power can a cpu draw with said cooler, but that also differs with different gens of cpus.

So you are saying that changing the cooler will change the tdp...? Cause I'm pretty much sure it will remain the same.

This is a classic example of the problem we have. TDP in modern usage is NOT CPU power consumption.

ya, i don't even look at the tdp given by intel and amd anymore lol, i have a ballpark estimate of how much each cpu draws. I had a fun guess of 220w b4 the 10900k released, i had a nice laugh when the reviews came out lol.

It's not that simple. For example, AMD's calculation for TDP includes the thermal resistance of the heatsink, which is chosen based on their stock cooler obviously. As such, and since it's inversely proportional, a better cooler effectively results in a higher TDP. However, practically, that then just shifts the numbers such that things like the junction temp or ambient temp can be higher, resulting in the same TDP. In other words, TDP doesn't change, but thermal headroom does because of a better cooler, which is pretty much just obvious.

What is the purpose of TDP?

The purpose of defining TDP is to provide system designers/integrators with a power target in order to help with proper thermal solution selection

 

 

Neither Intel or AMD include boost or turbo clocks in reference to TDP.

 

It is in fact (for AMD), and I'll use my 2700x for example, TDP is the rating for max p-state clocks and voltage, in my case 3.7ghz at 1.210v according to CPU-z txt report. 

Intel is similar, but TDP is the average BTU dissipation at load when not in boosted or turbo state.

 

That's why when you look at full turbo load, the TDP wattage consumption is higher than advertised. 

 

Then you convert that wattage to BTU to get an idea of how big a space heater you have.

 

Been going round and round with this conversation for years and years.

 

Back in 2005, the TDP accuracy became an average when Intel introduced "turbo" clocks.

 

Do some research, you'll see what I'm talking about.
