The Alienware X51 has one of the fastest on-board graphics adapter dynamic frequencies (1,250 megahertz) amongst personal computers of this age.
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 medium processor core personal computers that have been available for a comparable time to the X51 have between one and seven USB 3.0 (3.1 Gen 1) Type-A ports.
Very Fast Processor Clock Speed
The slowest processor clock speed of computers that have been on the market for a comparable time to the X51 is 1.3GHz, the fastest is 4GHz, and the average processor clock speed is 3.1GHz. When compared to other medium processor core personal computers that came out around the same time as the X51 that we have checked, the Alienware X51's processor clock speed of 4 gigahertz is one of the fastest.
Quite Big Hard Drive Capacity
The hard drive capacity of medium processor core personal computers that came out more than a year ago range from 1GB to 3TB. At 2,000 gigabytes, the Alienware X51 has a quite big hard drive capacity compared to most of the other medium processor core personal computers that have been around for around the same time as the X51.
Fairly Big Total Storage Capacity
At 2,000 gigabytes, the Alienware X51 has a fairly big total storage capacity compared to most of the other medium processor core personal computers that were launched more than a year ago. The average total storage capacity of similar spec desktop computers that are a comparable age to the X51 is 840GB, and the total storage capacity range from 4GB to 3.6TB.
+13 More reasons for
Fairly Big Internal Memory
At 16 gigabytes, the Alienware X51 has a fairly big internal memory compared to most of the other similar spec computers that are a comparable age to the X51. The internal memory of similar spec PCs that have been available for a comparable time to the X51 range from 2GB to 64GB, and the average internal memory is 8.3GB.
There are a number of other 16GB memory desktop computers currently available that you might also want to look at including the DELL Precision T5810[plb_2518973_price] which is cheaper.
L3 Processor Cache Level
This PC has a L3 processor cache level, which is the most frequently found processor cache level on personal computers that are a similar age to it.
Very Fast Maximum Turbo Frequency
Comparable spec personal computers that have been available for a similar time to the X51 have maximum turbo frequencies of between 1.8GHz and 4.4GHz, and the average maximum turbo frequency is 3.6GHz. With a maximum turbo frequency of 4.4 gigahertz, the Alienware X51's maximum turbo frequency is one of the fastest amongst medium processor core personal computers that are a comparable age to the X51.
3 PCI Express Slots Version
This PC supports a 3 PCI Express slots version, which is the most commonly supported PCI Express slots version on desktop computers of this age and type.
10/100/1000Base-T(X) Cabling Technology
This desktop computer has a 10/100/1000Base-T(X) cabling technology, which is typical of many similar spec PCs that were launched more than a year ago.
Six USB 3.0 Ports
Most comparable spec computers that were launched around the same time as the X51 have between one and seven USB 3.0 ports, including the Alienware X51 which has six USB 3.0 ports.
Eight Processor Threads
The Alienware X51 has more processor threads than most of the PCs that have been available for more than a year. This desktop computer is a eight processor thread personal computer compared to most of the comparable spec computers that were released one year ago which only have between four and seven processor threads.
Quite Big Processor Cache
The processor caches of desktop computers of a similar age and type to the X51 range from 2MB to 10MB. The Alienware X51 has one of the bigger processor caches (8 megabytes) amongst medium processor core personal computers of this age.
7.1 Audio Output Channel
This desktop computer has a 7.1 audio output channel, which is the most frequently found audio output channel on computers of a comparable age and type to it.
GDDR Discrete Graphics Memory Type
This PC supports a GDDR5 discrete graphics memory type, which is typical of many similar spec desktop computers that were released more than a year ago.
The Alienware X51 is one of the lighter similar spec desktop computers that are a comparable age to the X51 (only 5.5 kilograms) amongst similar spec PCs of this age. The lightest desktop computer of a similar age and type to the X51 is 38g heavy, the heaviest is 100kg, and the average weight is 7.5kg.
Across all the medium processor core personal computers that were released around the same time as the X51 the widths range from 33mm to 510mm, and the average width is 180mm. The Alienware X51 is one of the narrower PCs of this spec and age (only 95 millimeters) amongst medium processor core personal computers of this age.
7 Reasons Against
Alienware has good ratings for its medium processor core personal computers, however it has unexceptional average ratings when measured across its entire computer range.
Only HDD Storage Medium
The storage speed of this personal computer is HDD, which is the most frequently found storage medium on medium processor core personal computers that have been available 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.
Alternative HDD computers currently available that you might also want to look at include cheaper desktop computers such as the Lenovo P310[plb_3192626_price], or the HP 600 G2[plb_3765201_price].
If the storage speed of this Alienware PC is not fast enough for you then you might also want to look at the HP ProDesk 600 G2 MT[plb_3068722_price] (SSD), or the DELL 7040 Micro[plb_3139663_price] (SSD) which is also cheaper.
PCs of this age and spec range in price from £139 to £2,468. We think that this desktop computer looks expensive compared to other PCs of this age and spec.
Very Small Maximum On-Board Graphics Adapter Memory
PCs that have been available for around the same time as the X51 have maximum on-board graphics adapter memories of between 1GB and 64GB. The Alienware X51 has one of the smaller maximum on-board graphics adapter memories (only 1.024 gigabytes) amongst similar spec PCs of this age.
+4 More reasons against
Only Has One Memory Slot
The Alienware X51 has a greater number of memory slots than most computers of a comparable age and type to it. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this desktop computer. The memory slots 2x DIMM are also found on this computer.
Only Two USB 2.0 Ports
Most personal computers of this type and age have between one and nine USB 2.0 ports, including the Alienware X51 which has two USB 2.0 ports.
Quite Small Discrete Graphics Adapter Memory
With a discrete graphics adapter memory of only 2,048 megabytes, the Alienware X51 has a quite small discrete graphics adapter memory compared to most of the other computers of this age and type. The smallest discrete graphics adapter memory of computers that have been available for around the same time as the X51 is 4.9MB and the biggest is 8.2GB.
