The smallest internal memory of similar spec personal computers that have been around for more than a year is 2GB and the biggest is 64GB. The Alienware X51 has one of the bigger internal memory (16 gigabytes) amongst computers of this age.
3 PCI Express Slots Version
This desktop computer supports a 3 PCI Express slots version, which is typical of many computers that have been available for more than a year.
L3 Processor Cache Level
This computer has a L3 processor cache level, which is the most commonly found processor cache level on PCs of a comparable age and type to it.
Very Fast Maximum Turbo Frequency
Across all the medium processor core PCs that have been available for a comparable time to the X51 the maximum turbo frequencies range from 1.8GHz to 4.4GHz, and the average maximum turbo frequency is 3.6GHz. The Alienware X51 has one of the fastest maximum turbo frequencies (4.4 gigahertz) amongst medium processor core PCs of this age.
10/100/1000Base-T(X) Cabling Technology
This PC has a 10/100/1000Base-T(X) cabling technology, which is typical of many PCs that have been available for around the same time as it.
Six USB 3.0 Ports
The Alienware X51 is a six USB 3.0 port computer. Most of the other medium processor core PCs that have been available for a comparable time to the X51 have between one and seven USB 3.0 ports.
Eight Processor Threads
Most of the other comparable spec PCs that have been around for a similar time to the X51 only have between four and seven processor threads, however the Alienware X51 has eight processor threads.
Fairly Big Processor Cache
Medium processor core PCs that have been available for more than a year have processor caches of between 2MB and 10MB, and the average processor cache is 6.6MB. The Alienware X51 has a fairly big processor cache (8 megabytes) compared to most of the other PCs 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 most comparable spec desktop computers that have been around for around the same time as it. Most comparable spec personal computers that were released one year ago have a 5.1 audio output channel. Across all computers of this type and age the best audio output is 8.1 and the worst is 5.1.
GDDR Discrete Graphics Memory Type
This desktop computer supports a GDDR5 discrete graphics memory type, which is typical of many PCs that were released around the same time as it.
The lightest desktop computer of a comparable age and type to the X51 is 38g heavy, the heaviest is 100kg, and the average weight is 7.7kg. The Alienware X51 is fairly light (only 5.5 kilograms) compared to most of the other similar spec computers that have been around for around the same time as the X51.
The Alienware X51 is quite narrow (only 95 millimeters) compared to most of the other desktop computers of a comparable type and age to the X51. Personal computers that came out around the same time as the X51 have widths of between 33mm and 510mm.
8 Reasons Against
Quite Slow Max Memory Bandwidth Supported Processor
The slowest max memory bandwidth supported processor of medium processor core PCs that have been around for more than a year is 10GB/s, the fastest is 68GB/s, and the average max memory bandwidth supported processor is 29GB/s. The Alienware X51 has one of the slower max memory bandwidth supported processor (only 25.6 gigabytes per second) amongst computers of this age.
Very Small Max Internal Memory Supported Processor
The max internal memory supported processors of similar spec computers that have been on the market for a comparable time to the X51 range from 2GB to 770GB. The Alienware X51 has a quite small max internal memory supported processor (only 32 gigabytes) compared to most of the other PCs of a comparable age and type to the X51.
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 around 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 compared this PC to all the other HDD desktop computers and we think the HP Z230, and the DELL Precision T1700 which is cheaper is also worth considering.
This computer supports a 11.2 on-board graphics adapter DirectX version, which is typical of many desktop computers that have been available for a similar time to it.
+5 More reasons against
Only Has One Memory Slot
The Alienware X51 has a greater number of memory slots than most computers of this age and spec. 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 personal computer.
Only Two USB 2.0 Ports
Most similar spec desktop computers that have been around for a comparable time to the X51 have between one and nine USB 2.0 ports, including the Alienware X51 which has two USB 2.0 ports.
Very Small Maximum Internal Memory
With a maximum internal memory of only 16 gigabytes, the Alienware X51 has one of the smaller maximum internal memory amongst medium processor core PCs of this age. The average maximum internal memory of computers that have been available for a comparable time to the X51 is 32GB.
Quite Slow Memory Clock Speed
The Alienware X51 has one of the slower memory clock speeds (only 1,600 megahertz) amongst similar spec PCs of this age. Across all the comparable spec PCs that are a similar age to the X51 the memory clock speeds range from 1,000MHz to 2,400MHz.
