Cray GX

Cray GX is the successor architecture to Cray EX that was launched alongside the OLCF Discovery system.¹

It is 100% liquid cooled.

Cabinets are only 900 mm wide instead of 1,200 mm of Cray EX4000¹ and will use “25 percent less data center space per rack.” This implies that the rack depth remains comparable and the power per rack is comparable to Cray EX4000 (400 kW/rack).
