二、外观：与RX 6800 XT几乎一模一样

赠送一个RADEON鼠标垫，鼠标垫里面包着的是RX 6900 XT显卡。

外形与RX 6800 XT一模一样，正面有3个风扇，53mm 2.5槽厚度。

散热底座是大面积的均热板，理论上效率要强于热管，不过均热板挡同时住了散热器的风道，使得风扇难以吹透散热片，实际散热效能还是不及堆料的非公版。

14层PCB板设计，12+4相供电电路，理论上应付500W的功耗都没问题。

供电电路的钽电容在PCB板背面。

Navi 21 GPU核心，芯片面积519mm2，268亿个晶体管。

旁边是三星GDDR6显存颗粒，频率16GHz，单颗容量2GB，一共8颗组成256Bit 16GB，显存带宽达到了512GB/s。

纯铜均热板底座。
