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

Radeon R7 240 2GB offers a core codenamed Oland PRO and thus features 320 Shader Processing Units, 20 TMUs and 8 ROPs, on a 128-bit bus width of standard DDR3. While the central unit runs at 730MHz and goes up to 780MHz, in Turbo Mode, the memory clock operates at 900MHz.
With a rated board TDP of 30W, it requires no extra power connectors.

Compared to Radeon R7 250, its performance is significantly lower (over 25% slower), especially at higher resolutions due to the limited memory bandwidth.
Still, the TDP is relatively low and so this card may be used on low end systems and offer a reasonable upgrade, when compared to integrated graphics.
