With the fabrication process of 7 nm, the chips become very small. The size of the new Navi GPU cores in RX 5700 and 5700 XT is only 251 mm while the 14 nm Vega GPUs were 495 mm in size. Almost double. The Navi GPU is more efficient, but still, the thermal density is increased. Which is why these small chips benefit a lot from a more efficient way of cooling via our water blocks.
