I have a ATI 7750 that I mostly use with W7 x64 and it seems to perform equally well or better than a GTX 460 (same setup) even though the 460 scores much better in all benchmarks
I was looking for a direct replacement which seems to be the R7 250 but it's built upon different variants and this drives me crazy to find the right one. (it must be 2GB GDDR5 NOT DDR3)
...
the R7 350 doesn't have drivers for XP I wonder if older drivers may work with it....???????
surprinsingly the performance is the same or even worse than the R7 250 Cape Verde variant.... !!!!!!!

From what I see in the TechPowerUp spec sheets It is all practically the same or remarkably similar to the HD7750. All GCN 1.0 / 28nm. Only that some have 2GB where my HD7750 has 1GB memory.
GCN 1.0 is told quite different from the earlier Terascale architecture. Since it is the first version of a new architecture, it is bound to be a bit premature, and potentially prone to incompatibilities. Especially on Windows XP, because by then it was hardly worth the investment of their time.
What I have seen since with my HD7750, is some strange behaviour with VSync in OpenGL. Where it starts to stutter to various degrees. A reboot then fixes it for a good while, but I now have the habit of disabling VSync for OpenGL anywhere I can.
What I would be curious about, if there is any GCN 2.0 based card that can work in Windows XP x86. By the way, the AMD datasheets sometimes define GCN 2.0 as GCN 1.1.
For Linux, GCN cards are preferable, because they are supported by both the Radeon and AMDGPU driver. For a long time GCN 1.0 was not supported properly by the AMDGPU driver, because for GCN 1.0 it required an overly large firmware to make it work. If it wasn't for the Linux and Windows 7 multiboot, I would consider putting a HD6xxx back for Windows XP use.
