  • AMD A-Series APU Support  GIGABYTE A75 series boards feature an AMD A75 'Hudson' chipset supporting the latest 32 nm AMD A-Series APUs (Accelerated Processor Units). These processors are the first ever to combine a DX11-capable, high performance graphics processor with a choice of a dual or quad core CPU in one silicon die, offering a 3D gaming and multimedia experience similar to a discrete graphics configuration. The AMD A75 series platform showcases AMD Dual Graphics technology, allowing users to further boost 3D graphics performance by adding an additional discrete AMD Radeon HD 6000 series graphics card to the system.
  • AMD CrossFireX Supported Flexible graphics capabilities - Up to 2 VGA cards are supported for 2 way AMD CrossFireX (running at x8, x8 bandwidth), delivering the ultimate in graphics performance for gaming enthusiasts who demand the highest frame rates without compromising on resolution.
  • Super Safe All GIGABYTE Super4 motherboards boast specific features that guard against system malfunction and ensure extended system longevity, including GIGABYTE DualBIOS to ensure that you never experience system failure due to BIOS corruption. Additionally, each USB port has its own dedicated power fuse that prevents unwanted USB port failure, helping to safe guard your important data during transfer. All Super4 motherboards also use Solid Capacitors design that guarantee system longevity with a minimum 50,000 hrs lifespan.
  • Super Speed GIGABYTE Super Speed ensures that you’re always on the cusp of PC performance, data transfer and device charging speeds. GIGABYTE’s unique Ultra Durable series technology makes sure that your AMD processor is running at optimal performance levels, while GIGABYTE 3x USB power means better device compatibility and also allows iPad, iPhone and iPod devices to charge up to 40% faster. AMD A-series motherboards come with new generation APU able to provide ultimate DX11 graphics performance and additional up to 45% enhanced by AMD Dual Graphics technology.
  • Super Savings All GIGABYTE Super4 motherboards are equipped with the very best quality components that ensure that you PC is running at maximum power efficiency. Lower RDS(on) MOSFETs reduce energy wastage through unnecessary residual heat dissipation. This all amounts to tangible energy savings which are beneficial for both end-users and the environment without impacting system performance.
  • Super Sound As the HD multimedia revolution continues to gain momentum, so too must hardware standards in audio quality. All GIGABYTE Super4 motherboards offer excellent 7.1 surround sound audio backed by a proprietary converter that is able to achieve 108dB noise ratio (SNR) playback quality. This means that users will enjoy a better audio experience with lower levels of noise and hiss when enjoying the latest HD content.
