Possible Big Navi leak:
256-bit
128 ROP
WTF
Most likely Navi 22 but that is one hell of a ROP count. Or it's Navi 21 but the Engineering Sample might be old which could result in a low speed bus. Some more discussions if yall want to have a look:
AMD ES with 256 bit interface:@CapFrameX noted that *maybe* big caches can be helpful. @Locuza answered that this will not close the gap. Others believe, that we seeing a Navi 22 board here. @scottiefour4 noted that the GPU on that ES is 320-360mm² big, so probably not Navi 21. https://t.co/bidavi5ueC

If the die size(505mm2) and bandwidth(256bits) of Navi21 is true, someone said Navi21 will have a huge cache to explain the number. How do you explain it? There is a lot of discussion @3DCenter_org .
