Test: Request to purchase computer

Request to purchase computer

John, at our department meeting last week, I agreed to research the purchase of all the hardware for the new computer. The reason for the purchase is per our standard operating procedure of lifecycle replacement of our computers that are 5 years old. The research has yielded a clear preference, and I am ready to make the purchase.

Potential uses for the upgraded computer system

– Presentations
– Best graphic design for our clients

According to our specifications it is recommended that we purchase functional hardware to best suit our customer’s needs. The models and prices are listed in Table 1. Table 2 is the purchase for one of the vendors.

Component Specifications and importance

1) NAS
a. 4GB DDR3 RAM: expandable up to 16GB (8GB x2)
b. Hot Swappable: In the event a hard drive crashes you can swap it out without having to shut down the computer
c. External Ports: it supports 3.0, 2.0 and HDMI has the newest ports available and can backwards read older USB
d. PCIe Slots- able to add 2 more hardware cards
e. Compatible drive types- 4x 3.5 SATA 6Gb/s, SATA 3Gb/s hard drive, or 2.5-inch SATA, SSD hard drive

2) Hard drive
a. Capacity 2TB: holds a lot of data
b. Rational speed: speed is 5400RPM
c. Interface- SATA 6Gb/s: 64MB good transfer speed
d. drives are designed and extensively tested for compatibility in the unique 24×7 operating environment
e. buffer size is average latency between 5 and 60ms

3) Processor
a. 8 core processor 16 thread: This platform offers massive 16-thread performance and quad-channel memory for content creation, gaming and multitasking. The importance is performing complex tasks such as video editing or complicated science or math programs according to Mark Kyrnin.
b. Processor Base Frequency 3.60 GHz: The base frequency varies from model to model.
c. Max Turbo Frequency 4.30 GHz: The maximum base frequency is 4.7GHz on a single core being used the computer will not be running too slow.
d. Bus Speed 8 GT/s MB L3: It is important because it is it tells us how much data that can move across at once and how fast.
e. Thermal Design power 140W: The importance so we know how much TDP the component is drawing out. It will help us determine the correct cooling can we may need.

4) CPU Cooler
a. Heat Sink Material 4 Direct Contact Heat Pipes/Aluminum Fins: The importance is that the light weight of aluminum will put less stress on the motherboard.
b. Fan Life Expectancy 40,000hrs: The average life expectance is 30,000hrs, this will last longer than the average fan.
c. Bearing Type- Long Life Sleeve bearing-: A sleeve bearing fan is important because it is more economical; the temperature will not exceed 70 degrees in turn will have a lifetime expectancy.
d. Fan Noise Level (dB-A)- 9-36 dDA-: This fan is a quite fan we do not want a loud fan blowing that could cause one to be distracted.
e. CPU Socket- Intel Socket: LGA 2011/1366/1156/1155/775/1151; AMD Socket: FM1/FM2/ FM2+/ AM3+/ AM2+/ AM2; Intel: Core? I7 Extreme/ Core? I5/ Core? I3/ Core? 2 Extreme/Core?2 Quad/ core? Duo/ Pentium/ Celeron: If the CPU went out there are a variety of CPU that it could support.

5) Motherboard
a. Chipset- PRIME X299-DELUX: The importance of the chipset, according to Andrew Briggs, it is the backbone of the motherboard it is responsible for connecting every component to the motherboard.
b. Memory Speed- 4000(O.C.)/3600(O.C.)/2666/2400/2133 MHz Non-ECC, Un-buffered Memory. Memory speed is important because it determines how fast you receive or store data.
c. Memory Channel Supported- Quad Channel: This determines the memory bandwidth available on the CPU, which will help increase the performance.
Onboard LAN- Intel 1219V, Intel 1211-AT: The importance being able to connect to wired connection if you are only connecting with a wire.
e. Bluetooth- Bluetooth V4.1: The importance is it allows us to share data between paired devices.

6) RAM
a. Capacity- 16GB (8GB x2): The importance it is the physical hardware limitations.
b. Speed (MHz)- 3600 MHz: The speed is important it is dependent on bandwidth, total number of channels, and latency.
c. Cas Latency- 17: It is important because it is the time delay in the entered and executed command.
d. Voltage- 1.35V:
e. Multi-Channel kit- Dual Channel kit: It is important because it doubles the RAM access bandwidth on your computer.

7) Video Card
a. Core Clock-1556 MHz: it is important in that it is the speed of the cores on the GPU.
b. Boost Clock- 1670 MHz: The importance is that it is the maximum frequency the card will run at under nominal heat or power conditions, according to dangus explaining in a in tom’s hardware.
c. CUDA Cores- 3584: CUDA Core is important because the cores are responsible for processing all the data that goes into and out of the GPU.
d. DirectX- DirectX 12: It is important because it is an applications programming interfaces that is designed to handle tasks in 2D and 3D graphics on the Windows platform.
e. OpenGL- OpenGL 4.5: It doesn’t depend on a single programing language.

8) Power Supply
a. Wattage: You want to have enough power to may your new build functional, so it is best to go over rather than be under power.
b. Rail Specific Power: it is important because you need enough power to run all your components.
c. Dimensions; You want to make sure you power supply fits in your case and is compatible with your system.
d. Efficiency- 80 Plus Gold: This is important because you may want a system that reduces the operating costs.
e. Cables- fully modular cable sets: This is important because you need to know if you can install the power supply first or must have all the cable attached when installing.

9) Blu-ray
a. Performance- 14x;2x; 16x; 5x: The speed is important because you want to know the speed of how fast you can copy to a certain disc.
b. BDXL Disc
c. M-Disc
d. Interfaces types- SATA:
e. Compatible Writable Media- DVD-RAM; DVD+RW; DVD-RW; DVD+R DL; DVD+R SL; BD-R; BD-RE; BD-R DL; BD-R SL; Its import to know what kind of disc compatibility you can use with your disc drive.
