Quad SPI (QSPI; different to but has same abbreviation as Queued-SPI described in § Intelligent SPI controllers) goes beyond dual SPI, adding two more I/O lines (SIO2 and SIO3) and sends 4 data bits per clock cycle. Again, it is requested by special commands, which enable quad mode after the command itself is sent in single mode.
Thus, Intel describes a 20-lane QPI link pair (send and receive) with a 3.2 GHz clock as having a data rate of 25.6 GB/s. A clock rate of 2.4 GHz yields a data rate of 19.2 GB/s. More generally, by this definition a two-link 20-lane QPI transfers eight bytes per clock cycle, four in each direction. The rate is computed as follows: 3.2 GHz
Cooling air temperature can be improved with these guidelines: Supply cool air to the hot components as directly as possible. Examples are air snorkels and tunnels that feed outside air directly and exclusively to the CPU or GPU cooler. For example, the BTX case design prescribes a CPU air tunnel. Expel warm air as directly as possible.
AMD Wraith is a family of downdraft type CPU coolers designed by AMD. The Wraith was introduced as a heatpipe-equipped stock cooler for certain AMD FX CPUs and AMD A-series APUs. With the launch of AMD Ryzen, the Wraith lineup has been
Noctua is an Austrian computer hardware manufacturer of CPU coolers and computer fans with a primary focus on the enthusiast market. The company's inception occurred in 2005 through a joint venture partnership between the Austrian company Rascom Computer distribution Ges.m.b.H., established in August 2000, [2] and the Taiwanese cooling specialist Kolink International Corporation.
When the CPU is idle, it will draw far less than the typical thermal power. Datasheets normally contain the thermal design power (TDP), which is the maximum amount of heat generated by the CPU, which the cooling system in a computer is required to dissipate.
This heatsink is designed with the cooling capacity matching the CPU’s TDP. Thermal Design Power ( TDP ), also known as thermal design point , is the maximum amount of heat that a computer component (like a CPU , GPU or system on a chip ) can generate and that its cooling system is designed to dissipate during normal operation at a non-turbo ...
Peltier cooling plates / ˈ p ɛ l t i. eɪ / take advantage of the Peltier effect to create a heat flux between the junction of two different conductors of electricity by applying an electric current. [9] This effect is commonly used for cooling electronic components and small instruments.
