very unlikely to be "new" models, just a refresh of what we currently have that is instead of 14nm will be 12nm so maybe a few hundred Mhz more, or a slight reduction in power use idle/load/average, maybe default higher clock speeds and improved CoolNQuiet for those who overclock but want to retain the lower idle clock/voltage.
I wish they did this with graphics cards as well, would be very awesome to retain lowest clock/voltages not burn power pump heat for nothing..No reason why a gpu needs to run is memory at max clocks for anything but high load, they need to have more "steps" for the clock speeds i.e P1-5 type thing instead of only P0-P2, idle load, light load, mid load, performance load, extreme load or something along these lines.
anyways, I doubt they will be bringing completely new models out with just the nm change to accommodate a "refresh" might be why they have put some of the current Ryzen chips on sale cause they are planning on "bumping" some of them up in clock speed..example would be 1500x should be a few hundred mhz more than 1400, 1600x same, 1700 same, so maybe they are refreshing specific models in current Ryzen lineup to make more "range" so can justify the price differences a bit more clearly
IMO the "limit" of ~4-4.2Ghz is not a terrible thing as they still have LOTS of cores and great performance overall, if they could get them closer to 4.5Ghz would be excellent as long as power use and temperatures did not go through roof in the process, fact is Ryzen at 3.8-4.2Ghz is giving the same performance in nearly all cases as competing Intel models running 300-600Mhz more clock speed AND they give you more cores/more pci-e lanes and proper solder being used instead of cheaping out on paper thin dies and PASTE lol.
I wish Toms website page did not bounce around the page when viewing things for a few minutes each time, is like the graphics card is ramping up and down a few times throwing things off or something
