Spotted on Samsung's official Chinese site by Techpowerup.com, the Samsung 850 SSD, model MZ-7LN120, features Samsung's well-known MGX controller paired up with 3-bit MLC V-NAND and 256MB of LPDDR3 cache. Its sequential performance peaks at 540MB/s for read and 520MB/s for write, with a random 4K performance set at up to 88,000 IOPS for read and 70,000 IOPS for write.

Samsung also included a three year warranty or 75TBW, whichever comes first, and a reliability of 1.5 million hours.

Unfortunately, this is currently the only model listed without Pro/Evo suffix but others should probably follow soon.
