As we read in Cowcotland and in the Twitter account of ReHWolution, AMD seems to have stopped manufacturing its Radeon VII for not being economically viable, first before the strong competition of the RTX 2080 from Nvidia, and second since the recent RX 5700 XT has a performance only 5 or 10% more moderate than that of the VII for half the price. It is likely that the network also plans that the modified models of the RX 5700 that should arrive in mid-August will shorten the distance even further.
The XT, on the other hand, has a cheaper list of materials for the simplicity of its ASIC, the more conventional GDDR6 memory configuration and the lighter electrical components. The Radeon VII, remember, is based on a complex multichip module formed not only by a 7 nm GPU, but also four 32 Gbit HBM2 batteries, apart from a silicon intermediator. It has a more demanding voltage regulator module, too. In addition, the Vega architecture is out of phase with respect to Navi in performance-voltage ratio.
Now it’s time to ask how the high-end panorama for AMD will look forward. Seeing how Navi approaches performance-voltage parity, it is possible that Red will consider designing a larger Navi GPU, with a subsystem based on GDDR6, to try to plant Nvidia’s face back in the high-end.
