X1950XTX house the same GPU as X1900XTX, more precise the transistor-giant R580. Even if X1950XTX is code-named R580Plus which implies a change of the architecture this is not the case, if you neglect the GDDR4 updated memory controller. R580 is big but also a very powerful GPU which together with the improved bandwidth makes X1950XTX the most powerful single-GPU graphics card available on the market.

Below we've listed the most important specifications for X1950XTX. It's worth mentioning that the RAMDAC supports 10-bit colors all the way through the pipe, something ATI is the sole company to offer and results in a dramatic improvement of the color ratios when e.g. watching movies with the right TV.
