AMD recently showed industry partners, likely add-in board partners a presentation on the upcoming Radeon R9 390X. The presentation was leaked to the web via photographs taken of the slides and they look quite legitimate. The first slide shows the official specifications of the card. The first thing that sticks out is that the R9 390X WCE (water-cooled edition) will have 4096 stream processors! That is quite a jump compared to the 2816 the R9 290X has.
Other specifications include an engine clock up to 1050 MHz and 8GB of HBM memory. AMD has always been an earlier adopter of new memory technology and it looks like that is what they are doing with the R9 390X. Here is the leaked slide on HBM memory.
The AMD Radeon R9 390X will be the first graphics card with full support for DirectX 12. Tier 3 in the slide below means full hardware support.
It looks like there will be different versions of the R9 390X. The R9 390X WCE will be a special enthusiast edition that will be sold along with typical custom coolers designed by AMD’s AIB partners. It seems like the WCE edition will not be the only version available.
Finally we have a performance graph that shows the difference in performance compared to a Readeon R9 290X. These are just estimate results, but we are looking at a huge bump in performance up to 1.5-1.65x the performance of the R9 290X. These are 4K UHD charts too!
This looks like a very promising card and something that could bring great competition to NVIDIA’s GeForce GTX Titan X.
