Ok, I may be the only one to care, but I can't understand the "why's" of the names of the Ryzen CPUs. Especially the R5 line (but not only).

Actually we have this :

The RX marks the position in the line-up : R7 is high-end, R5 is mid-tier, and R3 will be entry-level.
This makes complete sense (and uses the numbers already used by Intel, so it's already acknowledged by consumers. Smart).

But bear with me still.

• R5 1600X : 6C/12T (high clock speeds)
  
• R5 1600 : 6C/12T (low clock speeds)

So far, this still makes sense : both CPUs share the same architecture and number of cores, so they have the same number = 1600. The only difference is in the clock speed (and the "auto-OC" capabilities). That is correctly marked by the "X", like in "PerforXmance".

But then it gets ugly :

• R5 1500X : 4C/8T (high clock speeds)
  
• R5 1400 : 4C/8T (low clock speeds)

We're still on mid-tier CPUs ($170-250), so those are still R5s. Okay.
But why, oh WHY go from 1400 to 1500X, when the step up is the same as from the 1600 to the 1600X : same architecture better performance. Either keep 1500/1500X, or 1400/1400X (to better differentiate from the 1600's), but don't mix them!

Then there's R7 that also does not completely make sense in that regard. :

• R7 1800X : 8C/16T (very high clock speeds)
• R7 1700X : 8C/16T (high clock speeds)
  
• R7 1700 : 8C/16T (low clock speeds)
  

Again, 1700 => 1700X is logical, but why the 1800 (and gratuitous X) when they are all the same chips !

For all the line, they should have kept strictly the first two digits to indicate the number of cores/threads. So a R5 can be either a R5 14 (4c/8t) or a R5 16 (6c/12). It's logical.
Then there are two other digits that can still be used to express the range inside of that architecture (and that's not even counting all the letters you can add).

(While we're here, and for mnemotechnic reasons, why not have those first two digits be the number of threads of the CPU ? We would have R7 16xx, R5 12xx, R5 8xx, etc... But I'm diverging.)

Right now, I find their line of CPUs hard to read in a glance. As a matter of fact, it's hard to remember which R5's will have which number of cores without resorting to the tables every time.
Am I crazy ? Am I the only one ? Is there anything else I'm not seeing ? PLZ SEND HALP !

EDITs : corrections on the R7 line-up

TL ; DR : the first two digits (after the RX) in the Ryzen naming scheme should always refer to the same architecture (number of cores/threads), which is not the case right now, and it makes no sense for me.
