It's a specification measured in watts that is found on pretty much any processor. It's meant to tell us the maximum amount of heat that component is expected to output in a realistic but heavy use scenario. Okay, but Lionus, hold on a second. I'm a bit confused. Isn't watts a measure of power consumption? I was planning out my new build and my friends told me that because the TDP and my graphics cards are 250 watts each that I need at least a 500 watt power supply. Hold on a second there, Charlie. Contrary to what you may have heard around the world's largest water cooler, TDP is not directly a measure of power consumption. But honestly, it's not your fault if you're a bit confused right now. A watt is a unit of measurement for energy over time. So that can refer to electrical power being consumed or the thermal power being output. And both uses are correct. To further complicate matters, even though TDP isn't a measure of power consumption, it's actually pretty directly related. So that is to say, a processor using the same manufacturing process and design architecture, but with a higher TDP will also consume more power. And besides, even if TDP was a power consumption rating, every manufacturer handles it slightly differently anyway. Often entire families of processors with significant differences in power characteristics and even thermal output can be assigned one blanket rating for convenience. Not to mention that while some manufacturers are basing it on a worst case scenario like prolonged heavy video editing, others are using it as more of a guideline for what a typical user should see in the real world. And then on top of that, no one accounts for the use of power viruses like Fermark, pieces of torture test software that are specifically designed to cause processors to exceed their TDP. Okay, Lionus. So, now that I understand what TDP is, why exactly should I even care about this if it doesn't help me choose my power supply? And all the manufacturers are basically making it up as they go. Anyway, great question. TDP is all about choosing an appropriate cooling solution. Processors need to be kept below a maximum operating temperature called Tjunction, at which point they will either stop working suddenly or engage advanced protection mechanisms to turn down their own performance to save themselves from being overheated and damaged. Not to mention that newer, more advanced processors can do more than just turn themselves down to prevent damage if you don't cool them adequately. Intel's Turbo Boost is an example of something that does just the opposite. If you've got more than adequate cooling and some power and thermal headroom to spare, this fascinating technology will actually allow the processor to temporarily exceed its normal TDP to give a small boost in performance on demand. I've actually done a full video about this. Check it out here. So, that is why aftermarket coolers for hot chips like CPUs and graphics processors are such a hot commodity. In the old days, they could make our computers run cooler and quieter and last longer. Well, now they can actually even improve performance in some cases, particularly when you're overclocking. And that specified TDP starts to go through the roof, which I guess leads us pretty well into our sponsor spot for today. Cooler Master has been making cooling solutions for processors since basically the dawn of time. So, if you're looking for all that stuff I just mentioned before, especially if you're an overclocker, a great way of saying thanks to them for sponsoring Techquicky would be to check out their extensive lineup of air and liquid cooling solutions.
