AMD themselfs lists an R9 M385X which is basically a souped up m380 and the list an M390x which is the same as a M395x probably slow clocked. It offers 1792 shader cores 28 compute cores clocked at 834. In 2012 used in the desktop 7870 graphics card and offers 1024 shader cores clocked at 958 MHz. AMD Radeon R9 M380 drivers available for Windows 10, Windows 8.1, Windows 7. The reason is that some software I'm using P3D constantly crashes due to a bug in the v15 driver and this is fixed in the latest driver.
It is completely ridiculous price to go from M395 to M395X.
