Information about the series and architecture of AMD A9-9420, as well as the release date of processor.
The processor series is marked with a number. The first digit indicates the processor generation. The following digits specify the device modification – the higher they are, the more powerful the CPU characteristics are.
A code name is typically chosen from the names of cities, rivers, lakes, and so on. For example, Intel traditionally gives its integrated circuit-based developments code names based on geographical names (since they cannot be registered as a trademark by anyone else): such as the names of cities, rivers, or mountains located next to Intel manufacturing facilities responsible for producing the corresponding circuit.
The main difference between a 64-bit system and a 32-bit system is that the latter is not capable of reading more than 4 GB of RAM. This applies not only to the main RAM, but to the one installed in the computer’s video card as well.
In the majority of cases, the later the release date, the more powerful and advanced the processor.
PCI Express (Peripheral Component Interconnect Express, abbreviated as PCIe or PCI-e) is a computer bus that utilizes a high-performance serial protocol. The main difference between its various versions is bandwidth capacity. The higher it is, the better.
The main technical characteristics of AMD A9-9420 processor.
A larger number of cores means that it is possible to distributed load between them. Due to this fact, your device is less likely to be overloaded.
When performing tasks, an operating system defines one physical CPU core as two logical ones. As it’s commonly known, multithreading makes it possible to increase the device operating speed. Which results in fact that it can receive more simultaneous commands. Moreover, if one logical core receives a task but fails to cope with it, with the second core being inactive, then the latter helps the first one with solving the task.
In general, the higher the clock speed, the faster the processor operates. But VsRank recommends paying attention to a number of other factors as well.
The maximum clock rate in Turbo mode means the maximum possible speed that can be reached when conditions make it possible for a processor to switch to Turbo mode. The speed of Intel Turbo Boost technology depends on workload, hardware and software, as well as the general system configuration.
L2 Cache (second-level cache of a processor) is slower if compared to L1, however it is larger in size. It can be from 256 kilobytes to 32 megabytes in volume. L2 cache contains data that a processor may need in future. The majority of up-to-date processors contain L1 and L2 caches directly on processor cores, with each core receiving its own cache.
Thermal design power (TDP) is a value that indicates an average thermal radiation of a processor when operating under load. The higher the processor power, the higher the requirements for its cooling system.
The smaller the technological process, which in other words means – the more perfect (more miniature) the technology, the more transistors fit in onto a chip of the same measure, which results in higher processor performance. At the same time, it reduces power consumption, as well as secures lower thermal radiation.
Characteristics of an integrated graphics processing unit. Support of 4K, clock speed, as well as video core memory capacity.
A video core is a model of an integrated graphics processing unit.
Radeon R5 (Stoney Ridge)
The boost technology promotes monitoring the graphics accelerator temperature and the consumed power, and should a critical load occur, it slightly increases the core speed and memory without breaking the safety limits.
A built-in video card doesn’t have its personal RAM, but uses the memory installed on the motherboard.
4K contains 3,840 pixels horizontally and 2,160 pixels vertically. 4K monitors resolution is generally specified as 3840 x 2160.
DirectX is a set of functions developed to provide easy and efficient solution of tasks related to multimedia, game and video programming for Windows operating systems by Microsoft.
Support by processors of such advanced technologies as multithreading, Turbo mode, AES cryptographic algorithm, and x86 AVX command system extension.
Virtualization technologies make it possible to create multiple logical systems on a single computer – in other words, isolated virtual machines with a complete set of functions of physical devices.
Turbo technology dynamically increases the processor frequency to the currently required level, using the difference between the nominal and the maximum values of the temperature and power consumption parameters, which makes it possible to increase power consumption efficiency or to “accelerate” processor should the need arise.
Multithreading is an ability of the central processing unit (CPU) or a single core within a multicore processor to execute multiple processes or threads simultaneously.
Advanced Encryption Standard, which is also known as Rijndael – a symmetric block encryption algorithm adopted as an encryption standard by the United States government based on the results of AES competition. This algorithm has been thoroughly analyzed and is widely used now, as it was the case with its predecessor DES.
Advanced Vector Extensions - x86 command system extension for Intel and AMD microprocessors, offered by Intel in March 2008. AVX provides various kinds of enhancements, new instructions and an advanced encoding scheme for machine codes.
Cinebench benchmark is a widely known and free computer performance test (testing a CPU and a video card). The program has been developed based upon MAXON Cinema 4D – a professional application for creating 3D animation.
A number of different tests including 3DMark06 CPU, SuperPI, Octane and many others.
