AMD Cripples Older GCN GPUs of Async-Compute Support?
AMD allegedly disabled asynchronous-compute technology support on older generations of Graphics CoreNext (GCN) architecture, since Radeon Software 16.9.2. With the newer drivers, "Ashes of the Singularity" no longer supports asynchronous-compute, a feature that improves performance in the game, on GPUs based on the first-generation GCN architecture, such as the Radeon R9 280X.
"Ashes of the Singularity" benchmarks run by Beyond3D forum members on GCN 1.0 hardware, comparing older drivers to version 16.9.2 shows that the game supports async-compute on the older drivers, and returns improved performance. AMD, on its part, is pointing users to a patch change-list from the developers of "Ashes..." which reads that the game supports DirectX 12 async-compute only on GCN 1.1 (eg: Radeon R9 290) and above.

As in, you know:
Edit: also, where's the post that claims support was dropped, it's not linked in the article...
Edit: If memory serves, GCN 1.0 only had 2 ACEs where GCN 1.1 and newer have 8 ACEs. That likely hampered their ability to do async compute hugely.
even if the issue lies solely on developer side and not AMD this is the after effect by pushing low level API. this is one of the thing that surely going to happen when looking at current game development trend.
C'mon guys, TPU is better then WCCFtrash, lets not stoop down to clickbait trying to bash one company or another. This is very true. When AMD has no real competitor to the 1070, 1080, titanXP, and no card that can match the 1050ti for low power consumption, there isnt much to say. It's already been established that there are only 2-3 480s and 470s worth buying, and that info is easy to scratch up. Until AMD brings vega or a 490, there isnt much to say.
nVidia:
GTX 1050 - 1
GTX 1050 Ti - 3
GTX 1060 - 8
GTX 1070 - 4
GTX 1080 - 2
GTX TPX - 1
AMD:
RX 460 - 1
RX 470 - 1
RX 480 - 4 (one of them is crossfire)
You do the math ...
Last month we had this one.
AMD Radeon GPUs Limit HDR Color Depth to 8bpc Over HDMI 2.0
Buyers should really be careful about buying "recycled" old GPUs.
Now where's that Report button...
"the specific thread you refer to actually had won "report of the month" just by the sheer quantity"
I can imagine the facepalms by the mods going on. :D
