14 Reasons For
A Best Selling Computer
The X51 is a popular choice of personal computer according to sales data from Amazon.
64-Bit Processor Operating Mode
This desktop computer supports a 32-bit|64-bit processor operating mode, which is typical of many comparable spec computers that were launched more than a year ago.
Six USB 3.0 (3.1 Gen 1) Type-A Ports
The Alienware X51 is a six USB 3.0 (3.1 Gen 1) Type-A port personal computer. Most of the other personal computers that have been available for more than a year have between one and seven USB 3.0 (3.1 Gen 1) Type-A ports.
Alienware medium processor core PCs have good reviews on average and across all personal computers Alienware is one of the superior manufacturers.
Quite Big Internal Memory
The smallest internal memory of PCs that were launched more than a year ago is 2GB, the biggest is 64GB, and the average internal memory is 8GB. With an internal memory of 8 gigabytes, the Alienware X51 has one of the bigger internal memory amongst comparable spec PCs of this age.
We compared this personal computer to all the other 8GB memory computers and we think the HP ProDesk 600 G1 ($1,465.28) which is cheaper is also worth considering.
If you are looking for a bigger internal memory then you might also want to look at the K31AD (12GB and cheaper), or the M32AD (16GB and cheaper) both from Asus or the Acer Aspire X3-710 (12GB and cheaper).
3 PCI Express Slots Version
This personal computer supports a 3 PCI Express slots version, which is the most commonly supported PCI Express slots version on desktop computers of this age and spec.
+9 More reasons for
L3 Processor Cache Level
This PC has a L3 processor cache level, which is the most commonly found processor cache level on computers of this spec and age.
10/100/1000Base-T(X) Cabling Technology
This personal computer has a 10/100/1000Base-T(X) cabling technology, which is the most frequently found cabling technology on computers that are a comparable age to it.
Six USB 3.0 Ports
Most computers that have been around for more than a year have between one and seven USB 3.0 ports, including the Alienware X51 which has six USB 3.0 ports.
Quite Big Discrete Graphics Adapter Memory
Across all the computers that have been on the market for more than a year the discrete graphics adapter memory range from 4.9MB to 8.2GB, and the average discrete graphics adapter memory is 2.9GB. The Alienware X51 has a quite big discrete graphics adapter memory (4,096 megabytes) compared to most of the other personal computers that are a comparable age to the X51.
7.1 Audio Output Channel
The Alienware X51 has a 7.1 audio output channel which is better than the 5.1 audio output channel found on most PCs of this age and type. Across all computers that were launched more than a year ago the audio output ranges from 5.1 to 8.1.
GDDR Discrete Graphics Memory Type
This desktop computer supports a GDDR5 discrete graphics memory type, which is the most frequently supported discrete graphics memory type on personal computers of a similar age and spec to it.
The Alienware X51 is one of the lighter medium processor core PCs that have been available for more than a year (only 5.5 kilograms) amongst medium processor core PCs of this age. The lightest medium processor core personal computer that is a similar age to the X51 is 38g heavy, the heaviest is 100kg, and the average weight is 7.7kg.
The Alienware X51 is one of the narrower desktop computers of this type and age (only 95 millimeters) amongst medium processor core PCs of this age. The widths of medium processor core PCs that were released one year ago range from 33mm to 510mm, and the average width is 180mm.
5 Reasons Against
Only HDD Storage Medium
The storage speed of this personal computer is HDD, which is typical of many medium processor core PCs that have been on the market for around the same time as it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.
We think you might also be interested in some of the other HDD personal computers currently available including the HP ProDesk 400 Mini which is cheaper.
If the storage speed of this personal computer is not fast enough for you then you might want to look at the OptiPlex 7020 SFF (SSD), or the Precision T1700 (SSD) both from DELL which is also cheaper.
Only 11 On-Board Graphics Adapter DirectX Version
This personal computer supports a 11.1 on-board graphics adapter DirectX version, which is typical of many PCs of a comparable type and age to it.
Quite Slow Hard Drive Speed
At only 5,400 revolutions per minute, the Alienware X51 has a very slow hard drive speed compared to most of the other comparable spec PCs that were launched more than a year ago. Desktop computers of this age and type have hard drive speeds of between 5,400 RPM and 7,200 RPM.
Only Has One Memory Slot
The Alienware X51 has a greater number of memory slots than most personal computers of this type and age. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this personal computer. The memory slots 2x DIMM are also found on this desktop computer.
+2 More reasons against
Only Two USB 2.0 Ports
The Alienware X51 is a two USB 2.0 port desktop computer.
4 Other reasons to consider the Alienware X51
Released Over a Year Ago
Alienware released the X51 over a year ago.
Average Processor Clock Speed
At 3.2 gigahertz, the Alienware X51 has a fairly typical processor clock speed compared to most of the other desktop computers of a similar type and age to the X51.
If this medium processor core personal computer processor clock speed is not fast enough for you then you might want to consider the DELL OptiPlex 7020 SFF (3.3GHz and cheaper); or the HP 800 G1 ($320.00) (3.3GHz and higher rated).
Average Hard Drive Capacity
At 1,000 gigabyte, the Alienware X51 has a relatively average hard drive capacity compared to most of the other personal computers of a comparable type and age to the X51.
There are a number of other 1TB hard drive capacity personal computers currently available that you might want to look at including the HP Z230 which is cheaper.
If you want a desktop computer with a bigger hard drive capacity then you might want to consider the H50 (2TB), or the H50 (2TB) both from Lenovo or the Acer Predator G3-710 (2TB) which is also cheaper.
+2 Other reasons
Average Total Storage Capacity
The Alienware X51 has a fairly typical total storage capacity (1,000 gigabyte) compared to most of the other PCs of this type and age.
We compared all the other 1TB total storage capacity computers to this computer and we think the HP Z230 which is cheaper is also worth considering.
If you would prefer a PC with a bigger total storage capacity then you might want to look at the H50 (2TB and cheaper), or the H50 (2TB and cheaper) both from Lenovo.
