Interesting it seemed here are more than 3 GP104 chips I knew GP104-400-A1 is GTX 1080, GP104-200-A1 is GTX 1070 and GP104-150-A1 is GTX 1080M for laptop:
GP104-200-A1 / GP104-PS-NB – ASUS’ teaser?
GP104-200-A1 / GP104-PR-DT / GeForce GTX 1070 / dev_id 1B81
GP104-200-A1 / GP104-PS-DT
GP104-400-A1 / GP104-PR-DT/ GeForce GTX 1080 / dev_id 1B80
GP104-400-A1 / GP104-PS-DT
GP104-725-A1 / GP104-PS-DT
GP104-950-KD-A1 / GP104-PR-DT
GP104-975-A1 / GP104-QS-9XX
GP104-985-A1 / GP104-QS-9XX
Hmmm I wonder what these mysterious GP104-725-A1, GP104-975-A1, GP104-985-A1 and GP104-950-KD-A1 all numbers higher than GTX 1080 are?
Something Nvida hide it from us, it could be that GTX 1080 is not the full chip and these 4 higher chips could contain more than 2560 CUDA cores? Higher clock speed? 384 and 512 bit bus? It possible Nvidia will launch these chips in case if AMD launch RX 490 soon.
GP106-300-A1 / GP106-QS-V0-F0-300-V1
GP106-400-A1 / GP106-QS-400-V1
GP106-750-A1 / GP106-QS-750
Interesting there are 3 GP106 chips, I think GP106-750-A1 will be GTX 1060 Ti with 256 bit bus confirmed on Zauba export data, GP106-400-A1 could be GTX 1060 with 192 bit bus and GP106-300-A1 could be GTX 1050 with 192 bit bus.
