AMD Radeon RX 6000 series Power Consumption and Memory Specs Leak
Starting with memory, AMD's reportedly using 16 Gbps GDDR6 memory modules for their flagship Navi21 XT GPU, likely using eight 16Gb (16GB total) K4ZAF325BM-HC16 DRAM chips from Samsung. AMD is likely to bundle their GPUs with GDDR6 memory when dealing with board partners. For their lower-end RDNA 2 Navi21 XL, AMD will likely use 14Gbps GDDR6 memory from Samsung with eight K4ZAF325BM-HC14 chips. AMD is also likely to source GDDR6 memory from other manufacturers.
According to Wallossek, availability for AMD's Navi 21 graphics cards will start in mid-November, only a few weeks after AMD's RDNA 2 launch on October 28th. Custom models from AMD's AIB partners should release in November, with AMD using PCB designs which are similar to existing Navi graphics cards to allow their AIB partners to reuse the design aspects of their existing Radeon offerings.
In terms of power consumption, AMD's Navi21 XT GPU is said to use 320W of total board power, making the GPU similar to Nvidia's RTX 3080. Custom Navi21 XL GPUs could consume as much as 355W, depending on how aggressive AMD's AIB partners are. Early reports of Navi21 XT consuming 235W of power are inaccurate, as this rating refers to GPU power, and not total board power.
For AMD's lower-end Navi21 XL silicon, total board power is expected to drop to 290W. This graphics is expected to use 203ish watts of GPU power.
AMD is due to reveal more about its Radeon RX 6000 series of graphics cards on October 28th, unveiling exact specifications for AMD's GPU lineup while also delivering true performance numbers for their RDNA 2 product line.

Would make more sense when manufacturers have 16Gb/2GB GDDR6X chips ready, but whether or not it will deliver enough gains for them tto consider the cost worthwhile for a refresh or something is still to be found out I guess.Quote
The 20 series does fine without it. It would just jack costs up even more and jack up the power use too.
Also I have a feeling that once again this should have been a low wattage card, but due to Nvidia's pre emptive strike and known performance AMD have cranked on the card again. Which they probably would have done regardless, as no one leaves anything in the tank now.
Hopefully they will be easier to get blocks for.Quote
It's looking more and more likely that AMD's top tier card from AIB partners will surpass a 3080, at least in some titles.Quote
