GIGABYTE kicked off its Radeon R7 300 and Radeon R9 300 graphics card lines, by leveraging its latest generation of in-house design WindForce cooling solutions, and custom PCBs. All the cards launched by GIGABYTE today, are factory-overclocked; some even bear the company's flagship G1.Gaming branding. The series begins with the GV-R736OC-2GD, based on the R7 360, with factory overclocked speeds of 1200 MHz core (vs. 1050 MHz reference); and a single 90 mm fan based heatsink cooling solution. Next up, is the GV-R737WF2OC-2GD/4GD, which comes in 2 GB and 4 GB variants, factory OC of 1015 MHz (vs. 975 MHz reference), and GIGABYTE's compact rendition of its WindForce 2X cooling solution.

Next up, is the Radeon R9 380 G1.Gaming SOC (GV-R938G1 GAMING-4GD), featuring 4 GB of memory, a minor OC of 990 MHz (vs. 970 MHz reference), and a surprisingly compact mid-tier WindForce 2X cooler in charge of taming this 190W chip. We then move on to the big boys, the R9 390 G1.Gaming and R9 390X G1.Gaming, with which GIGABYTE again surprises us with 2-slot, 2-fan WindForce 2X cooling solutions, handling the 275W cards. The R9 390 G1.Gaming ticks at 1025 MHz (vs. 1000 MHz reference); while the R9 390X G1.Gaming runs its core at 1060 MHz (vs. 1050 MHz reference).
