AMD TrueAudio is a kind of audio co-processor. Block diagram of HiFi Audio Engine DSP, which TrueAudio is based on. Shows the 56-bit wide MAC unit.. TrueAudio is AMD ' s application-specific integrated circuit (ASIC) intended to serve as dedicated co-processor for the calculations of computationally expensive advanced audio signal processing, such as convolution reverberation effects and 3D ...
AMD PowerNow! is AMD's dynamic frequency scaling and power saving technology for laptop processors. The CPU 's clock speed and VCore are automatically decreased when the computer is under low load or idle, to save battery power, reduce heat and noise .
3DNow! was developed at a time when 3D graphics were becoming mainstream in PC multimedia and games. Realtime display of 3D graphics depended heavily on the host CPU's floating-point unit (FPU) to perform floating-point calculations, a task in which AMD's K6 processor was easily outperformed by its competitor, the Intel Pentium II.
AMD PowerPlay is also implemented into ATI/AMD chipsets which integrated graphics and into AMD's Imageon handheld chipset, that was sold to Qualcomm in 2008. Besides the desirable goal to reduce energy consumption, AMD PowerPlay helps to lower the noise levels created by the cooling in desktop computers and extend battery life in mobile devices.
AMD K6-2 – an improved K6 with the addition of the 3DNow! SIMD instructions. AMD K6-III Sharptooth – a further improved K6 with three levels of cache – 64 KB L1, 256 KB full-speed on-die L2, and a variable (up to 2 MB) L3. AMD K7 Athlon – microarchitecture of the AMD Athlon classic and Athlon XP microprocessors. Was a very advanced ...
User control over Windows Updates is removed (except in enterprise versions). In earlier versions, users could opt for updates to be installed automatically, or to be notified so they could update as and when they wished, or not to be notified; and they could choose which updates to install, using information about the updates.
In addition to the CPU drivers offered by AMD, several motherboard manufacturers have released software to give the end user more control over the Cool 'n' Quiet feature, as well as the other new features of AMD processors and chipsets. Using these applications, one can even control the CPU voltage explicitly. PhenomMsrTweaker (SourceForge link)
AMD added a subset of SSE, 19 of them, called new MMX instructions, [3] and known as several variants and combinations of SSE and MMX, shortly after with the release of the original Athlon in August 1999, see 3DNow! extensions. AMD eventually added full support for SSE instructions, starting with its Athlon XP and Duron (Morgan core) processors.
