RX Vega Predictions

There is one thing worth remembering:

 

If Polaris can achieve 1,300MHz in the 580/70 and Vega's architecture is designed to achieve higher clock speeds, then that 1.2GHz from the engeenering sample used in the leaked benchmarks is not representative of the final performandce of the card.

Also, there's the idea (I don't remember where it comes from) that Vega will be a 12.5TFlops chip, which would put the end card at 1.5GHz.

The RX 580 tapped into those "Higher clocks" as well.

I am basing the Vega clock entirely on the 3D Mark leak. 1.2ghz isn't entirely unreasonable.

 

How so? Maybe not entirely... but there is still a fair amount of unreasonability going on there. The Fury X clocked at 1050 MHz on a 28 nm architecture. The jump to 14/16 nm alone increased clocks by some 30% on both AMD and Nvidia GPUs. And unlike Nvidia, for some reason the bigger AMD GPUs are the ones with the highest clocks. No reason for it to be below even the RX 460,  a first generation GPU held back by the desire to make it work on a PCI-e without extra power connections.
