Specifications are requirements of computers for technical details of components and functionality of the computer. These include information concerning speed, power, memory, graphics, and others. When you will purchase a printer, for example, it needs either Windows XP or Mac OS X 10.3 or higher. This requires a USB port and 80 MB of hard drive space available. If the device has no USB port you won't be able to connect the printer. The printer drivers may be incompatible with your operating system if your computer does not have Windows XP or Mac OS X 10.3 or higher. This means your computer will not recognize the printer. Correct Specifications from Relevant Sources Memory The RAM is measured in both Megabytes (MB) and Gigabytes (GB). The amount of RAM a computer requires depends on the software it needs to run efficiently. A computer running Windows XP will work with 1 GB of RAM, whereas for computers running Windows 7, a minimum of 2 GB will do. For the performance requirements of memory, look for the following: (1) Speed, typically expressed in megahertz (mhz) (2) Timing, generally known as CAS (Column Access Strobe) and (3) voltage. For most DDR4 modules the memory speed ranges from 2133MHz to 3200MHz. Example of Technical Specification: JEDEC Standard DDR3 Speed Grade : 1333Mbps Unbuffered DIMM : 240-pin https://www.mustangbols.com/animation-2d/perform Memory Organization : x8 FBGA DRAM chip DDR3 DRAM interface : SSTL_15 CAS latency : 9-9-9 Bandwidth : 10660MB/s Processor The Central Processing Unit (CPU) or processor is an integrated electronic circuit which carries out the calculations running a computer. A processor executes arithmetic, mathematics, input/output (I/O), and other simple instructions passed from an operating system. The speed of the processor chip of a computer is known as "clock speed" in gigahertz (GHz) units, with the latest modern processors operating at 4.7GHz currently. The following are the features to consider in selecting a processor: 1. Cores- since the functionality of multi-core processors have become more popular, and software has developed to use multi-core technology. There are some options to choose, from dual-core to 8-core processors. The "Core" family of processors includes Core 2, Core i3, Core i5, and Core i7, the last of which is the most powerful. 2. Cache-is a form of very fast memory channels that is inserted into the processor chip and used to store instructions to slow down as little as possible between tasks. A cache measures in Megabytes (MB), with low- end Celeron processors having as little as 0.25 MB of cache (256 KB), and high-end Itaniums with up to 24 MB. 3. Socket compatibility-enables the interface between the motherboard and its CPU. After you have already purchased a motherboard, confirm the processor mounted if it is compatible with its socket. 4. Integrated Graphics Processing Units (GPUs) -is designed to perform graphics-related calculations. If the processor does not have an integrated GPU, the computer can still display the graphics if there is a separate graphics card or if the motherboard offers an on-board video. 5. Frequency- the CPU frequency is measured in hertz (Hz). It is the speed the CPU that runs while working. If the CPU architecture operates at a lower frequency, it will potentially work better than a processor running at a higher frequency. 6. Front Side Bus (FSB) is a communication interface that acts as the major link between the CPU and system memory with the other parts of the chipset and motherboard. FSB speed is measured in hertz (Hz) and is also expressed as a ratio to CPU speed. It can range from 66 MHz to over 800 MHz. For example, a processor running at 2.4 GHz with an FSB of 400 MHz would have a CPU to FSB ratio of 6:1. Example Technical Specification: Essentials Product Collection : 7th Generation Intel® Core™ i5 Processors Processor Number : i5-7400 Performance # of Cores : 4 Max Turbo Frequency : 3.50 GHz Cache : 6 MB SmartCache TDP: 65 W # of Threads : 4 Bus Speed : 8 GT/s DMI3 https://www.mustangbols.com/animation-2d/perform Processor Base Frequency : 3.00 GHz Video Card Also known as graphics card, display adapter, video adapter, video board, or video controller, a video card is an expansion card that connects to a computer motherboard. It is a piece of hardware inside the computer that processes images and videos. The more efficient the GPU (Graphic Processing Unit), the faster information will be shown and better overall visual experience will be displayed. An overall indicator of the card's efficiency is its frame rate, expressed in frames per second (FPS). It shows how many full images a card can display per second. The human eye can process about 25 frames per second, but fast-acting games require a frame rate of at least 60 FPS to produce smooth animation and scrolling. The elements of frame rate are as follows: The triangles or verticals per second: 3-D pictures are composed of triangles or polygons. This measures how fast the GPU can measure the complete polygon or the vertexes. In general, it describes how quickly a wireframe image is constructed by the card. Pixel fill rate: This measures the pixels that the GPU can process in a second, which converts to how quickly the image could be scanned. The graphics card’s hardware directly affects its speed. Below are the hardware specifications that affects the speed of the card and the units in which it is measured: GPU clock speed (MHz) Size of the memory bus (bits) Amount of available memory (MB) Memory clock rate (MHz) Memory bandwidth (GB/s) RAMDAC speed (MHz Example Technical Specification Asus GeForce GTX 750 TI 2GB 128-bit GDDR5 performance graphics (GTX750TI- OC-2GD5) Graphics Engine NVIDIA GeForce GTX 750 Ti Bus Standard PCI Express 3.0 Video Memory GDDR5 2GB Engine Clock GPU Boost Clock : 1150 MHz GPU Base Clock : 1072 MHz CUDA Core https://www.mustangbols.com/animation-2d/perform 640 Memory Clock 1350 MHz ( 5400 MHz GDDR5 ) Memory Interface 128-bit Resolution DVI Max Resolution : 2560x1600 Interface D-Sub Output : Yes x 1 DVI Output : Yes x 2 (DVI-D) HDMI Output : Yes x 1 HDCP Support : Yes Power Consumption up to 150W1 additional 6 pin PCIe power required Software ASUS GPU Tweak & Driver ASUS Features OC Series Super Alloy Power Dimensions 8.58 " x 4.527 " x 1.53 " Inch 21.8 x 11.5 x3.9 Centimeter Data storage Data storage capacity is measured in bits (b) and bytes (B).
