More leaks about AMD’s Big Navi 21 XT … it appears it uses more power than previously mentioned. A whopping 320W TBP. Now’s pretty scary to say the least. Let’s hope they won’t have the same problems plagued by Nvidia.
Taken from Videocardz … Igor Wallossek published his first ‘big leak’ on Big Navi. According to his data, AMD Navi 21 XT will feature TGP at around 320W, not 255W as reported earlier. The difference comes from the wrong use of TGP nomenclature (Total Graphics Power) for both AMD and NVIDIA in an earlier report. Those values are not equal and do not represent the same thing (at least in that context), as Igor explains.
The values reported earlier were only representing the GPU socket power (GFX, SOC, and VDDCI). This is totally opposite to NVIDIA’s TGP, which represents the power consumption of the whole graphics card. That said, the value of 255W was only illustrating the socket power for the AIB card, not the power of the whole custom graphics card.
Taking that into the account, Navi 21 XT would have a stock GPU power of 235W. Thus the TBP (total board power) of AMD Radeon RX 6000 graphics card based on Navi 21 XT would be at around 320W. This number will increase to 355W for custom boards.
Igor also included the first GPU power values for Navi 21 XL, the cut-down variant. This model is allegedly featuring a TGP (or GPU power if you will prefer) of 203W with TBP expected at 290W.
