AMD APU GPU i have a question

[rainbowpirate]

hello all i'm new this is my first post, i'm studying game design and i am making a game advertising amd for the course. 

the game will have a "realistic" upgrade system  you will upgrade yore units with real AMD hardware APUs GPUs and then oc them and then stress test them my question is 

 

can i just line up the GPUs like  R7 250 [1]  R7 260x [1.5] R9 270x [2] R9 280X [2.5] R9 290X [3]      [ ] this is the power of them in the games eg real world performance

 

and line up the APUs    A4-5300[1]    A6-5400[1.5]   A8-5500[2]   A8-5600K[2.5]  A10-570[3] A10-5800K [3.5]

 

can i rank them by 0.5 increases like this Is this at least semi accurate and if not what should i change

i wouldn't but, you can if you want, but its really not too accurate tough, also what if they release new mid range cards? oh yeah and you're missing quite a few apus there

Your also missing the R9 270, and 290 along with the 7000 series of gpu's. Also are you going to incorporate cpus such as the FX series or Athalons?
