![]() ![]() The definition of the TGP from Quadro-Power-Guidelines.pdf: Looks like Radeon cards have less power loss than GeForce ones (30W for the RX 5700 against 45W for the RTX 2060)… This is interesting because we have a new information: the difference between the TGP and TDP which represents the power consumption of graphics memory sub-system + the power consumption of the power circuitry (VRM) itself. The power consumption of the whole graphics card is defined by the TGP or Total Graphics Power (or TBP for Total Board Power or Typical Board Power in AMD’s GPU specs…). Are “Thermal Design Parameter” and “Thermal Design Power” the same thing? The TDP does not reflect the total power consumption of a graphics card.Īt the same time, the TDP acronym is widely used to define the (total) graphics card power… But now, it seems it has a new meaning: according to the slide, TDP is the GPU power only (that could explain why NVIDIA calls it Thermal Design Parameter and not Thermal Design Power). For example, a TDP of 100W means the VGA cooler must be designed to dissipate heat equivalent to 100W. The TDP is the maximum amount of heat generated by the graphics card that a cooling system has to dissipate (the power is dissipated in the form of heat) under normal conditions (?). TBP: Total Board Power (or Typical Board Power, used by AMD).TDP: Thermal Design Power (or Thermal Design Point or Thermal Design Parameter).Power consumption is a term a bit vague because NVIDIA uses acronyms like TDP (widely used in the world of graphics cards) and TGP to talk about the power required by the graphics card. ![]() Looks like upcoming Radeon RX 5700 graphics cards do not leave the creator of GeForce GPUs indifferent, because NVIDIA has reacted by publishing this slide showing the power consumption of some GeForce vs Radeon cards: ![]()
