1. Performance of the Desktop Processor :
The Performance of the Desktop depends on the processing power of the CPU. Besides others, the Processor Core Frequency, number of cores, number of threads, the cache size, the Input/Output frequency and the RAM size defines the Processing Power. The nanometer size has been shrinking and the processor generations usually gets upgraded with the need to
accomadate more functionality in a single IC with the same or a smaller package size. The fully loaded running applications contributes to a good amount of heat and noise generation and an optimal design takes care of dissipating the heat and maintaining the decibel noise levels to satisfactory levels.
2. Desktop Connectivity :
It's all miniaturized and serial now a days. What does this mean? The ports that connect the Desktop to the outer world are decreasing in size and increasing in data transfer speeds. The serial Port standards on your Desktop has been constantly increasing the transfer speeds with the next generation of standard transferring data at a much faster speed probably with the same footprint or smaller. Take USB for example, the same sized port can be used to connect a keyboard at 1.5Mbps, Mouse at 12 Mbps, USB2.0 Pen drive at 480Mbps, USB 3.0 Pen drive at 5Gbps and USB3.1 Pen drive at 10Gbps. Even the Wireless standards are set for higher speeds. This is essentially driven by the consumer need of accomplishing tasks faster in relatively lesser time. Standards like HDMI, Display Port, Thunder Bolt, 802.11 Wireless have been constantly evolving with higher next generations transfer speeds compared to the previous ones. It's important to select the connectivity options matching them with the already existing accessories the ports need to connect with.
3. Desktop Display in All In One Desktop(AIO) :
Clarity of picture is the key. A 18.5 inch display with same clarity as a 23.5 inch Desktop display is better. Clarity depends on the Pixel count and the proximity of the pixels from each other for a given display size. PPI or Pixel per Inch would provide this information. In general a 4K UHD ( 4096 X 2160 pixels ) is better resolution than QUHD (3840×2160 pixels ), 2K( 2048 X 1080 pixels ) and FHD ( 1920x1080 pixels ) displays. Colour combinations and quality can play their role in selection. Higher colour combinations essentially means higher digital RGB combinations a display can support.
4. Desktop Dynamic Storage :
Dynamic Storage like Dual Data Rate Memory (DDR) plays it's part in improving the performance of the Desktop. The standards have evolved from DDR,DDR2,DDR3 to DDR4 ( DDR4 being the fastest) that essentially increases the read and write data speeds from/to the memory contributing to the increased performance.However, the maximum transfer speeds associated with the different memories needs to be looked at.
5. Desktop Static Storage :
Hard Disk Drive ( HDD ) and Solid State Drive ( SSD ) makes the static storage. HDDs comes in Terabytes now a days that is more than a 1024 Gigabytes and SSDs in Gigabytes usually. The higher the GB capacity, the more the storage option. Points to note are while HDDs comes with more capacity, SSDs are more reliable and faster because of their overall structure of not having any mechnical components like HDDs.
6. Desktop Form Factor :
Desktops come in different form factors ranging from All in One Desktop that is all electronics included in the Display structure, Tower, Small Form factor Tower,
Ultra Small Form Factor Tower, Mini and Micro Tower, Rack Desktops and Pocket PCs. Choose the one that suits your requirement the most.
