In Windows XP and 2000: Operating Systems "Minimal Power Management" profile must be active in "Power Schemes". A PPM driver was also released by AMD that facilitates this. [5] In Windows Vista and 7: "Minimum processor state" found in "Processor Power Management" of "Advanced Power Settings" should be lower than "100%".
CodeAnalyst by AMD: Linux, Windows C, C++, Objective C .NET, Java (works at the executable level) AMD uProf supersedes CodeAnalyst and CodeXL for CPU and Power profiling on AMD processors. GUI based code profiler; does only basic timer-based profiling on Intel processors. Based on OProfile. Free/open source (GPL) or proprietary AMD CodeXL by AMD
The power management for microprocessors can be done over the whole processor, or in specific components, such as cache memory and main memory. With dynamic voltage scaling and dynamic frequency scaling, the CPU core voltage, clock rate, or both, can be altered to decrease power consumption at the price of potentially lower performance. This is ...
ACPI 1.0 (1996) defines a way for a CPU to go to idle "C states", but defines no frequency-scaling system. ACPI 2.0 (2000) introduces a system of P states (power-performance states) that a processor can use to communicate its possible frequency–power settings to the OS. The operating system then sets the speed as needed by switching between ...
Overclocking BIOS setup on an ABIT NF7-S motherboard with an AMD Athlon XP processor. Front side bus (FSB) frequency (external clock) has been increased from 133 MHz to 148 MHz, and the CPU clock multiplier factor has been changed from 13.5 to 16.5. This corresponds to an overclocking of the FSB by 11.3 percent and of the CPU by 36 percent.
Set in 2011, the Guinness World Record for the highest CPU clock rate is 8.42938 GHz with an overclocked AMD FX-8150 Bulldozer-based chip in an LHe/LN2 cryobath, 5 GHz on air. [ 5 ] [ 6 ] This is surpassed by the CPU-Z overclocking record for the highest CPU clock rate at 8.79433 GHz with an AMD FX-8350 Piledriver -based chip bathed in LN2 ...

CodeXL's GPU profiler collects and visualizes hardware performance counters data, application trace, kernel occupancy, and offers hotspot analysis for AMD GPUs and APUs. . The profiler gathers data from the OpenCL runtime, and from the GPU/APU itself during the execution of the kernels, and can be used to discover performance bottlenecks and optimize kernel execut
