The upcoming NVIDIA GeForce GTX 750 and GTX 750 Ti on the Maxwell architecture have prompted AMD to work on a new video card that is known as Radeon R7 250X and will be positioned against the two newcomers.
The Radeon R7 250X will probably be a faster version of the currently available Radeon R7 250 graphics card. Not much is known about the card as of now except that it will have 1 GB or 2 GB of GDDR5 memory and a 128-bit memory bus. Unfortunately there’s no information on the GPU or the frequencies the card will run at. As to pricing the card will sell for around EUR 100 and less.
The official release date of the Radeon R7 250X is still unknown.
