Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
They introduced innovations such as modularized RAM chips, DVD (MPEG2) acceleration, notebook GPU card sockets, and "PowerPlay" power management technology. AMD recently announced DirectX 11-compatible versions of its mobile processors. [16] ATI CrossFire – This technology was ATI's response to NVIDIA's SLI platform. It allowed, by using a ...
In 2004, Intel released Intel High Definition Audio (HD Audio) which is a successor that is not backward compatible with AC'97. [2] HD Audio has the capability to define up to 15 output channels, but in practice most motherboards provide no more than 8 channels ( 7.1 surround sound ).
However, these features were dropped when AC'97 was superseded by Intel's HD Audio standard, which was released in 2004, again specified the use of a codec chip, and slowly gained acceptance. As of 2011, most motherboards have returned to using a codec chip, albeit an HD Audio compatible one, and the requirement for Sound Blaster compatibility ...
In 2017, Intel hired AMD’s graphics chip engineer, Raja Koduri, to lead a second effort toward a homegrown GPU. Three former executives say Koduri had a strong vision but was weak on execution.
In older Intel/AMD architectures the southbridge is usually linked to the northbridge, which in turn connected to the CPU. Circa 2004 and onward Intel architectures started to link southbridge directly to the CPU (e.g. via Direct Media Interface). Through the use of controller-integrated channel circuitry, the northbridge (or CPU itself) can ...
The chip company's stock price is up 72% in the last 12 months, beating out the broader S&P 500 , which is up 41%, and clobbering struggling Intel , whose stock price is down a staggering 35%.
High-resolution audio (high-definition audio or HD audio) is a term for audio files with greater than 44.1 kHz sample rate or higher than 16-bit audio bit depth. It commonly refers to 96 or 192 kHz sample rates. However, 44.1 kHz/24-bit, 48 kHz/24-bit and 88.2 kHz/24-bit recordings also exist that are labeled HD audio.
