  • TGP (Total Graphics Power) is to be taken as guidance for thermal and power delivery for customers using Intel® Arc™ A-Series notebook SKUs.
  • TBP (Total Board Power) is to be taken as guidance for thermal and power delivery for customers using Intel® Arc™ A-Series desktop/add-in card SKUs.
  • On Intel® Arc™ A-Series graphics processors, we cannot measure the TGP/TBP using software tools provided by Intel or through 3rd parties.
  • Power metrics reported through software tools only provide GPU Power; this is a subset of TGP/TBP.

 

Term GPU Form Factor Description
TGP
(Total Graphics Power)
Notebook

TGP represents a GPU's total graphics power when computing a typical workload.

TGP includes GPU Power + Power Losses + Graphics Memory Power.

Each GPU has a defined TGP range that can operate when computing; for example, A570M has a TGP range of 75-95W.

TBP
(Total Board Power)
AIC (add-in card)

When computing a typical workload, TBP represents the total power draw of an AIC (add-in card) GPU.

TBP includes TGP + Non-Graphics Power (Fans, LEDS).

Each AIC GPU has a maximum TBP to operate up to; for example, A770 has a TBP of 225W.

GPU Power Notebook/AIC GPU Power is the power given to GT to compute workloads. GPU Power will be equal to the defined PL1/PL2 when computing a typical workload. 
Power Losses Notebook/AIC Power lost through efficiency, including voltage regulator, RPath, and PCB losses. 
Graphics Memory Power (VRAM) Notebook/AIC Power consumed by the VRAM on the GPU. Power consumption will vary by 3D workload and number of memory units.
PL1 & PL2
(Power Limit)
Notebook/AIC Power Limits define the maximum GPU SoC Power; in some cases, it may also include Graphics Memory Power depending on board design.


Intel will be working to enable reporting of additional power metrics in future product and software releases.
