This computer supports a 32-bit|64-bit processor operating mode, which is typical of many similar spec computers that have been around for around the same time as it.
Six USB 3.0 (3.1 Gen 1) Type-A Ports
The Alienware X51 R2 is a six USB 3.0 (3.1 Gen 1) Type-A port PC.
Quite Big Hard Drive Capacity
The smallest hard drive capacity of similar spec PCs that have been on the market for around the same time as the X51 R2 is 1GB and the biggest is 3TB. With a hard drive capacity of 2,000 gigabytes, the Alienware X51 R2 has one of the bigger hard drive capacity amongst medium processor core computers of this age.
Quite Big Total Storage Capacity
The Alienware X51 R2 has a fairly big total storage capacity (2,000 gigabytes) compared to most of the other comparable spec computers that have been around for a similar time to the X51 R2. Computers that are a comparable age to the X51 R2 have total storage capacity of between 4GB and 3.6TB.
Fairly Big Internal Memory
Across all the medium processor core computers that came out around the same time as the X51 R2 the internal memory range from 2GB to 64GB. The Alienware X51 R2 has a quite big internal memory (8 gigabytes) compared to most of the other desktop computers that have been available for around the same time as the X51 R2.
We compared this computer to all the other 8GB memory personal computers and we think cheaper personal computers such as the Zoostorm Intel Core i5 Delta (£521.82) is also worth considering.
If this personal computer internal memory is not big enough for you then you might want to look at the Asus K31AD (£722.38) (12GB and cheaper).
On average Alienware medium processor core computers have good reviews as do all computers produced by Alienware.
+10 More reasons for
10/100/1000Base-T(X) Cabling Technology
This desktop computer has a 10/100/1000Base-T(X) cabling technology, which is the most commonly found cabling technology on comparable spec desktop computers that have been on the market for more than a year.
L3 Processor Cache Level
This PC has a L3 processor cache level, which is the most commonly found processor cache level on similar spec PCs that have been available for a comparable time to it.
3 PCI Express Slots Version
This computer supports a 3 PCI Express slots version, which is the most commonly supported PCI Express slots version on medium processor core computers that have been around for around the same time as it.
Six USB 3.0 Ports
The Alienware X51 R2 is a six USB 3.0 port computer. Most of the other comparable spec personal computers that were launched more than a year ago have between one and eight USB 3.0 ports.
Quite Big Discrete Graphics Adapter Memory
The discrete graphics adapter memory of medium processor core computers that have been around for more than a year range from 4.9MB to 8.2GB. The Alienware X51 R2 has one of the bigger discrete graphics adapter memory (4,096 megabytes) amongst similar spec PCs of this age.
Three Storage Drives
The Alienware X51 R2 is a three storage drive desktop computer. Most of the other medium processor core computers that have been available for more than a year have between one and five storage drives.
GDDR Discrete Graphics Memory Type
This personal computer supports a GDDR5 discrete graphics memory type, which is typical of many PCs of a comparable age and spec to it.
The average weight of personal computers that have been available for more than a year is 7.6kg, and the weights range from 38g to 23kg. The Alienware X51 R2 is one of the lighter medium processor core computers that have been available for around the same time as the X51 R2 (only 5.5 kilograms) amongst personal computers of this age.
The Alienware X51 R2 is fairly narrow (only 95 millimeters) compared to most of the other medium processor core computers that have been around for more than a year. Across all the PCs that were launched around the same time as the X51 R2 the widths range from 33mm to 510mm, and the average width is 190mm.
8 Reasons Against
Only HDD Storage Medium
The storage speed of this personal computer is HDD, which is the most commonly found storage medium on medium processor core computers that are a comparable age to 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.
If you would prefer a desktop computer with a faster storage speed then you might want to consider the HP EliteDesk 800 G1 (SSD and cheaper), or the Fujitsu D556 (£459.78) (SSD and 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 computers of this spec and age.
Only Two USB 2.0 Ports
Most comparable spec desktop computers that have been available for around the same time as the X51 R2 have between one and nine USB 2.0 ports, including the Alienware X51 R2 which has two USB 2.0 ports.
Only Has One Memory Slot
The Alienware X51 R2 has a greater number of memory slots than most PCs of this type and age. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this Alienware computer. The memory slots 2x DIMM are also found on this personal computer.
+5 More reasons against
Very Small Maximum On-Board Graphics Adapter Memory
Across all the medium processor core computers that have been available for a similar time to the X51 R2 the maximum on-board graphics adapter memories range from 1GB to 64GB, and the average maximum on-board graphics adapter memory is 2.8GB. The Alienware X51 R2 has one of the smaller maximum on-board graphics adapter memories (only 1.024 gigabytes) amongst computers of this age.
Very Small Maximum Internal Memory
The smallest maximum internal memory of computers of this type and age is 2GB, the biggest is 520GB, and the average maximum internal memory is 33GB. With a maximum internal memory of only 16 gigabytes, the Alienware X51 R2 has a fairly small maximum internal memory compared to most of the other medium processor core computers that were released around the same time as the X51 R2.
Quite Small Processor Cache
The Alienware X51 R2 has a fairly small processor cache (only 6 megabytes) compared to most of the other similar spec computers that have been available for a comparable time to the X51 R2. Across all the computers of this age and type the processor caches range from 2MB to 10MB, and the average processor cache is 6.6MB.
Only Four Processor Threads
The Alienware X51 R2 is a four processor thread personal computer.
2 Other reasons to consider the Alienware X51 R2
Released Over a Year Ago
Alienware released the X51 R2 over a year ago.
Average Processor Clock Speed
At 3.2 gigahertz, the Alienware X51 R2 has a relatively typical processor clock speed compared to most of the other personal computers of this age and spec.
If this Alienware desktop computer processor clock speed is not fast enough for you then you might also want to consider the OptiPlex 9020 (£419.39) (3.3GHz and cheaper), or the OptiPlex 3020 SFF (3.3GHz and cheaper) both from DELL or the HP ProDesk 400 SFF (£490.40) (3.3GHz and cheaper).
