The average CPU power (ACP) is the power consumption of central processing units, especially server processors, under "average" daily usage as defined by Advanced Micro Devices (AMD) for use in its line of processors based on the K10 microarchitecture (Opteron 8300 and 2300 series processors). Intel's thermal design power (TDP), used for ...
When the CPU uses power management features to reduce energy use, other components, such as the motherboard and chipset, take up a larger proportion of the computer's energy. In applications where the computer is often heavily loaded, such as scientific computing, performance per watt (how much computing the CPU does per unit of energy) becomes ...
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)
On AMD processors, from 180nm Athlon onwards (AuthenticAMD Family 6 Model 2 and later), it is possible to modify the processor brand string returned by CPUID leaves 80000002h-80000004h by using the WRMSR instruction to write a 48-byte replacement string to MSRs C0010030h-C0010035h.
The AMD Jaguar Family 16h is a low-power microarchitecture designed by AMD. It is used in APUs succeeding the Bobcat Family microarchitecture in 2013 and being succeeded by AMD's Puma architecture in 2014. It is two-way superscalar and capable of out-of-order execution.
The AMD Bulldozer Family 15h is a microprocessor microarchitecture for the FX and Opteron line of processors, developed by AMD for the desktop and server markets. [1] [2] Bulldozer is the codename for this family of microarchitectures. It was released on October 12, 2011, as the successor to the K10 microarchitecture.
On June 11, 2013, AMD announced two additional FX-series eight Piledriver core CPUs, the FX-9590 and FX-9370, running at a maximum turbo speed of 5.0 GHz and 4.7 GHz respectively, making AMD the first company to ever release a 5 GHz CPU commercially. [19] AMD specify that the 9xxx series processors require "robust liquid cooling" due to their ...
In each socket resides an AMD Athlon 64 FX CPU. Each socket is connected using AMD's Direct Chip Module, this dual-processor architecture was dubbed by AMD as the "Dual Socket Direct Connect Architecture" (DSDC Architecture), [5] providing a dedicated channel between the CPU cores and from each CPU out to the system memory. Due to the nature of ...
