Igor Wallossek, from Igors Lab, today revealed information about TGP (Total Graphics Power) consumption that will have a graphics card based on AMD Navi21 XT silicon, which will be between 320 and 355W, and not the 255W that we already put in doubt a couple of days ago and we said that it could be around 350W of consumption. The difference comes from the incorrect use of the TGP (Total Graphic Power) nomenclature. For both AMD and Nvidia, these values are not the same and do not represent the same for both companies.
The 255W mentioned are the sum of 235W for the GPU together with the 20W consumption of the 16 GB of GDDR6 memory, but adding the rest of the components that give life to the GPU, we are talking about a TBP (Total Board Power) consumption in around 320W, or about 355W if we talk about a Custom model. The AMD Radeon RX 6000 that has the cut silicon, the Navi21 XL, will be around 290W of consumption.
On the other hand, it is revealed that the high-end AMD Radeon RX 6000 uses Samsung K4ZAF325BM-HC16 memory chips, which would reach a frequency of 16 GHz, at least in the reference models, not knowing if the partners will develop Custom models with memories of some other manufacturer and with other frequencies. We are 8 days away from the AMD Radeon RX 6000 Series launch event, so the leaks will start to intensify.
