AMD Radeon RX 6000 series Power Consumption and Memory Specs Leak

Some fresh information about Big Navi’s power consumption has dropped thanks to the efforts of Igor Wallossek, revealing the power consumption and memory specifications of AMD’s upcoming RDNA 2 powered Navi21 XT and Navi21 XL graphics cards. 

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.
