The consumption of the AMD RX 6000 based on Navi 21 XT would be between 320W and 355W

There is very little left for AMD to introduce us to its RX 6000 graphics cards based on the RDNA2 architecture. While this is happening, there are a lot of leaks regarding these graphics cards. Igor Wallossek, from Igor's Lab has indicated what would be the total consumption of a graph based on Navi 21 XT silicon, the basis for the hypothetical RX 6900 XT.

A few days ago it was leaked that the top-of-the-range AMD Radeon RX 6000 GPU would have a consumption of about 255W. Finally, the data are different and it is that consumption could be more than expected. The TGP (Total Graphics Power) of the Navi 21 XT would be 320W for the assembler model and 355W for the custom models.

The AMD RX 6000 based on Navi 21 XT would have a high consumption

According to rumors, the Navi 21 XT silicon could reach 2.4GHz, which is a very high power. Initially, there was talk of a 255W TGP, but finally this consumption would be the sum of the GPU and VRAM. Silicon consumes 230W and the 16GB VRAM would have a consumption of 20W. The 65W of additional consumption suppose the consumption of other elements and of the losses by heat and other losses.

The TBP (Total Board Power) of the assembler model has a consumption of 320W and for the custom models it would be 355W. That the custom models have higher consumption is because the Navi 21 XT silicon would arrive with factory overclocking.

Perhaps the most interesting data is the model of the GDDR6 memories that the RX 6000 will use. The Samsung K4ZAF325BM-HC16 chips will arrive with a frequency of 16GHz, in the case of the reference models. Each of the chips has 2GB of capacity, so if they finally have 16GB of VRAM, they will have 8 memory chips.
