Lisa Su says " Our Ryzen processors at launch will have base clock speeds of 3.4 Ghz or higher" . The slide says 8C/16T and 3.4 Ghz+ , not 3.4 Ghz - . My interpretation is that the lowest base clock of 8C/16T Ryzen processors will be 3.4 Ghz. If there is a single 8C/16T SKU it could be base clock of 3.4 Ghz or higher. Alternatively we could have two 8C/16T SKUs with the slower 8C/16T at 3.4 Ghz and a faster flagship SKU at 3.6 Ghz. I am pretty sure the 6C/12T and 4C/8T SKUs will have even higher base clock speeds.
