Gigabyte joined the growing list of AMD Radeon add-in board partners to launch Radeon R9 270X graphics cards with double the standard memory amount. The GV-R927XOC-4GD, available in a standard edition and one with a Battlefield 4 Origin key, features 4 GB of GDDR5 memory across a 256-bit wide memory interface, clocked at 5.60 GHz, at which the GPU has 179 GB/s of memory bandwidth at its disposal. The card features a long, non-reference design PCB, and the company's new generation WindForce 3X cooler, which together give the card a high-end look when installed. 4 GB of memory makes the R9 270X meet the recommended system requirements of Battlefield 4. The factory-overclocked card offers 1050 MHz base GPU clock, and 1100 MHz PowerTune Boost frequency. The card draws power from a pair of 6-pin PCIe power connectors, display outputs include a pair of dual-link DVI, and one each of HDMI 1.4a and DisplayPort 1.2. Based on the 28 nm "Curacao" silicon, the Radeon R9 270X features 1,280 GCN2 stream processors, 80 TMUs, and 32 ROPs. It features a 256-bit wide GDDR5 memory interface. Its API support includes DirectX 11.2, OpenGL 4.3, and Mantle. Gigabyte didn't reveal pricing of the two.
