HDMI
The HDMI specification defines the protocols, signals, electrical interfaces, and mechanical requirements of the standard.[39] The maximum pixel clock rate for HDMI 1.0 was 165 MHz, which was sufficient for supporting 1080p and WUXGA (1920×1200) at 60 Hz. HDMI 1.3 increased that to 340 MHz, which allows for higher resolution (such as WQXGA, 2560×1600) across a single digital link.[40] An HDMI connection can either be single-link (Type A/C) or dual-link (Type B) and can have a video pixel rate of 25 MHz to 340 MHz (for a single-link connection) or 25 MHz to 680 MHz (for a dual-link connection). Video formats with rates below 25 MHz (e.g., 13.5 MHz for 480i/NTSC) are transmitted using a pixel-repetition scheme.
memoria DDR3
The primary benefit of DDR3 SDRAM over its predecessor, DDR2 SDRAM, is the ability to transfer at twice the data rate (8× the speed of its internal memory arrays), enabling higher bandwidth or peak data rates. In addition, the DDR3 standard allows for chip capacities of up to 8 gigabits, thus enabling a memory module size of 16 gigabytes (using 16 chips).
With two transfers per cycle of a quadrupled clock, a 64-bit wide DDR3 module may achieve a transfer rate of up to 64 times the memory clock in MB/s.
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2 modules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V. The 1.5 V supply voltage works well with the 90 nanometer fabrication technology used in the original DDR3 chips. Some manufacturers further propose using "dual-gate" transistors to reduce leakage of current.
Intel HD Graphics
Intel HD Graphics with dynamic frequency up to 1GHz delivers smooth HD video playback and mainstream 3D gaming without the need for add-in video cards or decoders. It also supports a wide range of display connectivity options and is dual display capable.
USB 3.0 and SATA III
The USB 3.0 technology is natively built into the chipset to provide up to 5Gbps bandwidth for blazing fast data transfer. The SATA III interface enables up to 6Gbps link speed - twice the speed of SATA revision II to take full advantage of the latest SSD storage technology.
