What is the TGP of a Graphics Card and How is it Different from the TDP?

With the arrival of the AMD Radeon RX 5700, a new parameter was introduced in the graphics card specifications that has not even left NVIDIA indifferent, as they were quick to report it as well. This is the TGP , and in this article we will explain what it is, how it differs from the TDP and why you should take it into account.

Until now, the power consumption of graphics cards was a somewhat vague term because of NVIDIA, which started using acronyms like TDP to define it. However, luckily, now things have changed and both NVIDIA and AMD are much more specific about it, so let’s see what TGP has to do with all this.

TGP of a Graphics Card and How is it Different from the TDP?

What is the TGP of a graphics card?

TGP is the acronym in English for ” Total Graphics Power “, or “total graphic consumption” if we translate it into Spanish. It is, in fact, the power consumption that the GPU of the graphics card has, and it comes to replace the way in which we defined until now the TDP. It is also called TBP for “Total Board Power” or “Typical Board Power” in the case of AMD graphics, and defines the total consumption of the graphics including GPU, memory, VRMs, etc.

Therefore, when we are looking at which power supply is the most suitable for our system taking into account the graphics card, the parameter that we must take into account is the TGP and not the TDP, because it is the one that will tell us the total consumption of the device. And, as we were saying, now both manufacturers already indicate this in their product specifications, even in the professional range.

How is TDP different from TGP?

TDP comes from the English acronym Thermal Design Power (also known as Thermal Design Point and Thermal Design Parameter), and refers to the amount of heat the graphics card heatsink needs to be able to dissipate based on the heat generated by the GPU. For example, a 100 watt TDP means that the graphics sink must have been designed to dissipate that amount of heat, and does not reflect GPU consumption.

However, now both AMD and NVIDIA use it contrary to what happens in processor heatsinks, to express the consumption only of the GPU.

In summary, these are the terms that we can find:

  • TDP: Thermal Design Power, the amount of heat the heatsink must be able to dissipate. In graphics they use it to express the consumption of the GPU only, not of the graphics as a whole.
  • TGP: Total Graphics Power, the total power consumption of the graphics card.
  • TBP: Total Board Power, equivalent to the previous one.
  • GPC: Graphics Card Power, equivalent to the previous ones.
  • MPC: Max Power Consumption. In some cases we can see this term, and it refers to the peak power that it consumes at most.

All in all and with that, NVIDIA continues to reluctantly use it. For example, in the Whitepaper of the Turing architecture graphics it continues to express it in TDP but then indicates that it refers to the consumption of the GPU only.

So, from now on when you look at the specifications of a graphics card you should know that the TDP refers to the consumption of the GPU only, while if they indicate the TGP, then it is the total consumption of the graphics.
