Sure. My comment was predicated on the idea that the clocks on the chips with lower core count could be somewhat indicative of the overclocking potential (since total power consumption shouldn't be as limiting a factor with 4 cores as it is with 8 or 6). With Intel, you get 6 cores at significantly higher base clocks than 8, and 4 cores at significantly higher base clocks again than 6, while in that table it looks pretty flat.
It's possible that they're just being conservative with stock TDPs as an attempt to win points on power consumption after years of power-hogging Bulldozer designs. We know that at least one of their 8-core chips is a 95W TDP part (where Intel's 8-core i7s have all been rated at 140W). They may want to clock their 4-core chips relatively low in order to bring their TDP in under the 7700/6700's 65W at stock clocks, knowing that enthusiasts will overclock anyway.
Alternatively it could be a binning thing. Unlike Intel, whose 4 core and 6/8 core models are different dies, AMD is binning a single die from 4 to 8 cores, and as the 8 core chips would likely be the best performing parts, and the 4 core models the worst, the performance variation across the bins may be large enough to cancel out the typically increased clock scope of lower core count parts.
Early March, but that doesn't mean shit when we're in early February. AMD probably won't reveal any new info before the middle of the month, just to make sure Intel can't fuck them over.
That said, the so-called full Ryzen lineup seems super absurd to me, unless it's their entire lineup for the next 4 years or something. That said, AMD really needs to get more official info out there, because there's so many fucking rumors out there right now.
Keep in mind that Intel's desktop Kaby Lake lineup currently consists of 23 different models:
5 x Pentium
8 x Core i3
7 x Core i5
3 x Core i7
AMD releasing 17 models is actually somewhat modest in comparison (particularly as AMD are also competing with Intel's HEDT chips).
I'd also be willing to bet that a lot of these are duplicates with and without their Wraith cooler. At a guess, the "Pro" models come with the Wraith cooler, the X models with no cooler at all (matching Intel's K models) and the rest come with AMD's cheaper stock cooler. That leaves just two clock steppings per core/thread count. By comparison, Intel is currently shipping dual-core, quad-thread Kaby Lake chips at
10 different clock speeds.
I do think it's a bit foolish to use R5 for both their 4C/8T products and their 6C/12T models, though. It would have perhaps made a bit more sense to use R7 for the 6C and R9 for the 8C models, or just lumped all the quad-core chips together as R3, to keep the performance jumps clear to customers as you go up the line.
