Tech site WCCFTech uncovered the above slide and did a bit of maths based upon the graphs. It came to the conclusion that the upcoming Zen CPU, as performance charted above, will be direct competition for the octa-core Intel Core i7 5960X. There's quite a lot of assumptions in there, considering the sketchy graphs, with the one on the right probably (but not necessarily) sharing the same axes/scale as the other graph.

On the topic of the upcoming Zen processors, a wafer shot of AMD's octa-core Summit die is thought to have been 'accidentally' revealed by AMD at its shareholder's meeting earlier this month. Tech commentators over at SemiAccurate are largely of the opinion that the wafer shot reveals that each Zen module will comprise of; four cores, an L3 cache in the centre and a DDR4 interface on top, with a South Bridge to the top right. Furthermore some suggest that on the bottom right of the chip is a Global Memory Interconnect (GMI) for chip-to-chip communication.
