Canard PC tested an 8-core Ryzen processor with 3.15/3.4GHz base/boost. Canard PC tested an AMD '2D3151A2M88E4' processor. This is but one of four ES processors distributed by AMD to its hardware partners (there were 2x quad core and 2x octacore chips as detailed above). These ES processors seem to run at conservative clock speeds. For example the Canard PC sample was clocked at base/boost of 3.15/3.4GHz. Note that AMD announced that top-end shipping Ryzen chips would have a 3.4GHz base clock.
