Note: This Graphics Card has 2 variants: one with DDR3 and another with GDDR5. This is the GDDR5 Version.

Radeon R7 240 v2 2GB offers a core codenamed Oland PRO and and thus features 320 Shader Processing Units, 20 TMUs and 8 ROPs, on a 128-bit bus width of fast GDDR5. While the central unit runs at 730MHz and goes up to 780MHz, in Turbo Mode, the memory clock operates at 1125MHz.
Also, it offers a frame buffer of 2GB though this will not boost its performance and can be addressed as a gimmick - marketing to lure consumers into paying more for the same product.
With a rated board TDP of 30W, it requires no extra power connectors.

Its performance is somewhat comparable to GDDR5 variant of Radeon HD 7730.
