TechPowerUp GPU-Z (or just GPU-Z) is a lightweight utility designed to provide information about video cards and GPUs. [2] The program displays the specifications of Graphics Processing Unit (often shortened to GPU) and its memory; also displays temperature, core frequency, memory frequency, GPU load and fan speeds.
Memory diagnostic software programs (e.g., memtest86) are low-cost or free tools used to check for memory failures on a PC. They are usually in the form of a bootable software distribution on a floppy disk or CD-ROM. The diagnostic tools provide memory test patterns which are able to test all system memory in a computer.
After MemTest86 remained at version 3.0 (2002 release) for two years, Samuel Demeulemeester created the Memtest86+ fork to add support for newer CPUs and chipsets. From version 1.60, the program can output a list of bad RAM regions in the format expected by the BadRAM patch for the Linux kernel [13] (similar to MemTest86 2.3).
The Tegra APX 2500 was announced on February 12, 2008. The Tegra 6xx product line was revealed on June 2, 2008, [1] and the APX 2600 was announced in February 2009. The APX chips were designed for smartphones, while the Tegra 600 and 650 chips were intended for smartbooks and mobile Internet devices (MID).
These sensors, after being calibrated at the factory, are able to provide digital data concerning processor temperature information. The PECI bus , allowing access to this data from chipset components, is a proprietary single-wire interface with a variable data transfer speed (from 2 kbit/s to 2 Mbit/s).
GPU performance data, an extension to expose information about the GPU hardware such as temperature, fan speed, clock speeds for engines and memory, memory bandwidth, power draw, and voltages. SupportContextlessPresent , a driver cap to help IHVs onboard new driver.
In-depth device info about battery temperature, battery level, and CPU load changes. 8 [18] 17-10-2019 Introduces new Vulkan test scene-Terracotta Warriors. Updates all the test items in Memory test. Includes the display of hardware details in benchmark results page. Includes CPU architecture info in My device section. Fully supports Android Q.
Landauer's principle is a physical principle pertaining to the lower theoretical limit of energy consumption of computation.It holds that an irreversible change in information stored in a computer, such as merging two computational paths, dissipates a minimum amount of heat to its surroundings.
