Powercolor is one of the first partners which has announced its own Radeon R7 250X graphics card.
Although all official AMD slides suggest that the upcoming Radeon R7 250X should pack 640 Stream Processors and be based on Cape Verde GPU and pretty much be a rebrand of the previously released HD 7770 GHz Edition, Powercolor's R7 250X packs 512 Stream Processors, which slightly less than expected. It also packs 1GB of GDDR5 memory paired up with a 128-bit memory interface.
According to details from Powercolor, the new R7 250X works at 1000MHz for the GPU while memory ended up clocked at 1125MHz (4.5GHz effective).
It is still unclear if it was a mere typo on Powercolor's side or there will actually be some R7 250X graphics cards with 512 Stream Processors, which should further complicate things.
Unfortunately, Powercolor did not shed any light regarding the actual price or the availability date.
