Thanx but a few ??:GMI and xGMI are basically the same link, but with different type of configuration (width), speed and error tolerance.
GMI is the internal form (inter-die) and has bandwidth of 42.6GB/s per direction at 2666MHz MEMCLK.
xGMI is the external form (inter-node, i.e. EPYC only), has the same bandwidth at the same MEMCLK but different speed, width and error tolerance.
Isnt threadripper using xgmi then as well as epyc?
How can xgmi have same bandwith as gmi? And what is meant with "speed"? And how is "width" defined physical?
