If you dissect the installation file from the Catalyst 15.3 driver as released last week then you will find some new entries, all AMD Radeon Rx 300. There's good and bad news though.
The bad news is that most cards seem to be respin products, meaning an older GPU being reused onto a new PCB and BIOS, often with subtle clock frequency differences. If you couple the device ID's to previous generation products then you will see that older GPUs are in use for the following products up-to R9 370.
Catalyst 15.3 Beta shows:
- AMD665F.1 = “AMD Radeon R9 360″
- AMD6610.2 = “AMD Radeon(TM) R7 350X”
- AMD6610.3 = “AMD Radeon(TM) R5 340X”
- AMD6611.10 = “AMD Radeon R7 340″
- AMD665F.1 = “AMD Radeon R9 360″
- AMD6660.1 = “AMD Radeon(TM) R5 M330″
- AMD6660.2 = “AMD Radeon(TM) R5 M330″
- AMD6660.3 = “AMD Radeon(TM) R5 M330″
- AMD6778.8 = “AMD Radeon R5 310″
- AMD6811.1 = “AMD Radeon R9 370″
That means AMD Radeon R9 370 would be Trinidad (=Pitcairn) aka Radeon HD 7870 and 265/270/270X. The AMD Radeon R9 360: Tobago would be Bonaire with 896 shader processors. And then AMD Radeon R7 350X, R7 340 and R5 340X would use Oland with its 384 stream processors.
Missing entries are the AMD Radeon R9 380 and R9 390. Now if you allow me to speculate for a moment, given all these re-spins logic would dictate that the 380 could very well be a spin of Hawaii (290/290x). But again that is speculation.
If that is the case then the only new GPU would become the R9 390/390X series.
