AMD Radeon RX 6000 with RTX 3000 power consumption.

IN BRIEF:

  • youtuber Igor Wallosek calculated that the total power consumption factor (TBP) of the Radeon RX 6900 XT card is 320 W;
  • non-reference models can draw up to 355 W from the socket;
  • the weaker Radeon RX 6900 will need about 290 W;
  • both cards are reported to have 16 GB of VRAM.
  • The well-known youtuber Igor Wallosek reports that Radeon RX 6000 graphics cards have a great appetite for electricity. In his analysis, the expert indicates that in the case of AMD, the TGP index revealed in recent leaks cannot be compared with the TGP used by Nvidia. The first stat takes into account only the current consumed by the GPU and VRAM, while the second one takes into account the entire graphics card (with cooling and all other components needed for operation). In the case of “red” Nvidia’s equivalent to TGP is TBP.

    Igor used the calculation method previously used for the GeForce RTX 3090 (in that case he managed to calculate the power consumption with almost perfect accuracy – he was only wrong by two watts) to determine the likely real power demand of the Radeon RX 6000. the fact that the TBP factor of the most powerful graphics chip from AMD – Radeon RX 6900 XT (Navi 21 XT) – will be 320 W. This means that the card will require roughly as much power as the GeForce RTX 3080 it is going to compete with.

    As with Nvidia cards, non-reference designs can feature even greater demand for electricity, reaching even 355 W.

    On the other hand, Navi 21 XL, i.e. the weaker Radeon RX 6900 (without the XT suffix) most likely it will pull about 290W from the socket.

    Reports also suggest that both GPUs will have 16 gigabytes of VRAM. In the case of the more powerful Radeon, it will have a speed of 16 Gbps, which translates into 512 GB / s of throughput. The weaker card will be equipped with slower chips (14 Gbps), guaranteeing 448 GB / s of throughput.
