Following the launch of two factory-overclocked, WindForce-equipped Radeon R9 200 graphics cards, Gigabyte rolled out its entry-level Radeon R7 200 series, with five models based on the Radeon R7 260X, Radeon R7 250, and Radeon R7 240. To begin with, the company launched three kinds of R7 260X graphics cards, by reusing two of its PCB designs for the "Bonaire" silicon, the GV-R726XWF2-2GD revisions 1 and 2 (pictured in that order). A third variant is based on a simpler fan-heatsink cooler. The three cards come with identical factory-overclocked speeds of 1188 MHz core (vs. 1100 MHz reference), while leaving the memory untouched, at 6.50 GHz. The cards feature 2 GB of GDDR5 memory, across a 128-bit wide memory interface.

Moving on, the company launched a Radeon R7 250 graphics card, the GV-R725OC-1GI. Based on the 28 nm "Oland" silicon, the chip integrates 384 stream processors, 24 TMUs, 8 ROPs, and a 128-bit wide GDDR5 memory interface, holding 1 GB of memory. The card comes with factory-overclocked GPU core clock speed of 1100 MHz (vs. 1050 MHz reference), and 4.60 GHz memory. Lastly, there's its toned down version the Radeon R7 240, based on the same chip, and board design, the GV-R724OC-2GI, featuring factory-overclocked 900 MHz core (vs. 780 MHz reference), and 2 GB of DDR3 memory clocked at 1.80 GHz.
