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 personal computers of a comparable spec and age to it.
Two PCI Express X1 (Gen 2.x) Slots
The ThinkCentre E73 is a two PCI Express x1 (Gen 2.x) slot personal computer. Most of the other computers that came out more than two years ago have between one and two PCI Express x1 (Gen 2.x) slots.
At only 160 millimeters, the ThinkCentre E73 is fairly narrow compared to most of the other comparable spec computers that were launched more than two years ago. The average width of comparable spec computers that have been on the market for a similar time to the ThinkCentre E73 is 200mm.
9 Reasons Against
Only Two USB 3.0 (3.1 Gen 1) Type-A Ports
The ThinkCentre E73 is a two USB 3.0 (3.1 Gen 1) Type-A port PC.
Quite Slow On-Board Graphics Adapter Dynamic Frequency
With an on-board graphics adapter dynamic frequency of only 1,100 megahertz, the ThinkCentre E73 has a fairly slow on-board graphics adapter dynamic frequency compared to most of the other similar spec computers that came out more than two years ago. The slowest on-board graphics adapter dynamic frequency of PCs of a comparable type and age to the ThinkCentre E73 is 850MHz and the fastest is 1,300MHz.
Quite Slow Processor Clock Speed
Across all the medium processor core computers that came out more than two years ago the processor clock speeds range from 1GHz to 4.1GHz, and the average processor clock speed is 3.1GHz. The ThinkCentre E73 has a quite slow processor clock speed (only 2.7 gigahertz) compared to most of the other medium processor core computers that were released more than two years ago.
If you are looking for a faster processor clock speed then you might want to consider the DELL OptiPlex 9020 (2.9GHz and cheaper).
Only HDD Storage Medium
The storage speed of this computer is HDD, which is typical of many personal computers of a comparable age and spec 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.
Alternative HDD PCs currently available which you might also want to consider include the HP ProDesk 400 G2 which is cheaper.
The ThinkCentre E73 has a greater number of memory slots than most personal computers of a comparable spec and age to it. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this computer. The memory slots 2x DIMM are also found on this personal computer.
Only One 3.5" Bay
The Lenovo ThinkCentre E73 is a one 3.5" bay desktop computer.
Only Two USB 3.0 Ports
The Lenovo ThinkCentre E73 is a two USB 3.0 port computer. Most of the other personal computers of this age and spec have between one and seven USB 3.0 ports.
Quite Small L3 Cache
With a L3 cache of only 6 megabytes, the ThinkCentre E73 has a quite small L3 cache compared to most of the other desktop computers of a similar age and spec to the ThinkCentre E73. Across all the desktop computers of this age and type the L3 caches range from 2MB to 10MB, and the average L3 cache is 7MB.
Quite Slow Maximum Turbo Frequency
Medium processor core computers that were released more than two years ago have maximum turbo frequencies of between 1.3GHz and 4.4GHz, and the average maximum turbo frequency is 3.6GHz. The Lenovo ThinkCentre E73 has one of the slower maximum turbo frequencies (only 3.2 gigahertz) amongst medium processor core computers of this age.
4 Other reasons to consider the Lenovo ThinkCentre E73
Released Over Three Years Ago
It was over three years ago when this Lenovo PC was released.
Average Total Storage Capacity
With a total storage capacity of 500 gigabytes, the Lenovo ThinkCentre E73 has a pretty typical total storage capacity compared to most of the other desktop computers of a comparable age and type to the ThinkCentre E73.
We compared this PC to all the other 500GB total storage capacity PCs and we think the HP EliteDesk 800 G1 which is cheaper is also worth considering.
If this medium processor core computer total storage capacity is not big enough for you then you might also want to consider the Alienware X51 (2TB).
Average Hard Drive Capacity
At 500 gigabytes, the ThinkCentre E73 has a fairly standard hard drive capacity compared to most of the other PCs that are a comparable age to the ThinkCentre E73.
We think you might also be interested in some of the other 500GB hard drive capacity desktop computers currently available including cheaper PCs such as the HP EliteDesk 800 G1.
If this medium processor core computer hard drive capacity is too small for you then you might want to look at the Alienware X51 (2TB).
+2 Other reasons
Average Internal Memory
At 4 gigabytes, the ThinkCentre E73 has a fairly typical internal memory compared to most of the other medium processor core computers that came out around the same time as the ThinkCentre E73.
There are a number of alternative 4GB memory computers currently available which you might want to look at including the HP EliteDesk 800 G1 which is cheaper.
PCs with a bigger internal memory that might also be worth looking at include the OptiPlex 9020 (8GB), or the OptiPlex 9020 Micro (£390.00) (8GB) both from DELL which is also cheaper.
