Radeon R9 270X
The Radeon R9 270X uses a graphics processor called Curacao XT. After reviewing the technical characteristics of the GPU, it is easy to see that this solution is based on the well-known Pitcairn XT chip, which is used for the Radeon HD 7870.
The processor includes 1280 compute units, 80 texture units and 32 rasterization units. In the case of the R9 270X, the operating clock frequency of the GPU has been increased from 1000 to 1050 MHz, i.e. by 5%. A 256-bit bus is still used to access the memory, but the operating frequency of the chips has been noticeably increased - from 4800 to 5600 MHz. Considering the constant width of the highway, the bandwidth of the memory subsystem in this case increased by 16.7% - from 153.6 to 179.2 GB / s. As befits a mid-range solution, the base version of the Radeon R9 270X is equipped with 2 GB of RAM, while modifications with double the amount of memory will also be offered.
