A new AMD presentation slide hit the Internet a couple of hours ago, leaking some new interesting information about AMD’s upcoming high-end GPU, the R9 390X. According to the slide, AMD’s R9 390X will pack 4096 shader units, will support DX12 up to Tier 3 (in other words, DX12_3) and will feature up to 8GB of VRAM (basically meaning that we might get an initial 4GB version and afterwards a new updated 8GB version).
Here are the major features of AMD’s R9 390X:
- Next iteration of the highly successful GCN design * Up to 4096 shader units
- Full DirectX 12_Tier 3 implementation
- Optimized for 4K gaming & beyond
- First ever GPU designed for VR immersion
- Special enthusiast water-cooled edition
- Up to 8GB of ultra-high bandwidth HBM video memory
- Hardware H.265 decoding and over 4x the previous H.264 encoding speed, enabling smooth live streaming
- Enhanced ZeroCore functionallity (yes there’s a typo)
Regarding DX12’s Tiers:
“Tier 3 hardware such as AMD GCN has no limitations, allowing fully bindless resources managed through dynamic memory heap, while Tier 1 (Nvidia Fermi, Intel Haswell/Broadwell) and Tier 2 (Nvidia Kepler/Maxwell-1/Maxwell-2, Intel Skylake) hardware impose some limits on the number of these resources.”
AMD has not confirmed yet the specs of its upcoming high-end GPU, so take everything with a grain of salt.
