+11 More reasons for
Has a Full-Size Keyboard
Like most of the other portable PCs of this type and age, the Lenovo ThinkPad E540 has a full-size keyboard.
Intel Core I7 Processor Family
This portable PC has an Intel Core i7-4xxx processor family, which is typical of many comparable spec portable PCs that have been on the market for a similar time to it.
Has a Front Camera
The ThinkPad E540 has a front camera, as do most of the other similar spec laptops that have been around for a comparable time to the ThinkPad E540.
We compared all the other laptops with a front camera to this laptop and we think because of it's better review score, the Toshiba Satellite L50-C (£279.00) is also worth considering.
1,600MHz Processor Memory Clock Speed
The ThinkPad E540 supports a 1,600MHz processor memory clock speed which is faster than the 133MHz processor memory clock speed supported by most laptops that came out around the same time as it. This portable PC also supports 1 and 333MHz processor memory clock speeds. The best memory clock speeds supported by processor of all notebook PCs of a similar age and type to the ThinkPad E540 is 1,866MHz and the worst is 133MHz.
Eight Processor Threads
The Lenovo ThinkPad E540 is a eight processor thread notebook PC. Most of the other portable PCs of this age and spec only have between four and seven processor threads.
Fairly Big Processor Cache
At 6 megabytes, the ThinkPad E540 has a quite big processor cache compared to most of the other portable PCs of this age and spec. The smallest processor cache of similar spec portable PCs that were released one year ago is 2MB, the biggest is 8MB, and the average processor cache is 4.2MB.
L3 Processor Cache
The Lenovo ThinkPad E540 has a L3 processor cache which is better than most notebook PCs that were launched more than a year ago. Most many processor core portable PCs that have been on the market for a comparable time to it have a L2 processor cache.
A L3 processor cache is actually the best processor cache level across all similar spec notebook PCs that have been on the market for a comparable time to the ThinkPad E540.
A L2 processor cache is the worst processor cache level amongst similar types of portable PC.
802.11n WiFi Standard
This laptop has an 802.11a|802.11b|802.11g|802.11n WiFi standard, which is typical of many notebook PCs of a similar type and age to it.
Fairly Big Hybrid Hard Drive (H-HDD) Cache Memory
The smallest hybrid hard drive (H-HDD) cache memory of portable PCs of this type and age is 8GB and the biggest is 32GB. With a hybrid hard drive (H-HDD) cache memory of 16 gigabytes, the ThinkPad E540 has a very big hybrid hard drive (H-HDD) cache memory compared to most of the other many processor core portable PCs that have been available for a similar time to the ThinkPad E540.
10 Mbit/s Ethernet LAN Data Rate
This notebook PC Ethernet LAN data rate, which is the most frequently found Ethernet LAN data rate on many processor core portable PCs that were released around the same time as it.
3 Reasons Against
Only HDD Storage Medium
This laptop has a Hybrid-HDD storage medium, which is typical of many many processor core portable PCs that have been on the market for a similar time to it. HDD is a traditional storage drive which stores the information on magnetic disks. HDD drives are slower than other forms of storage such as solid state drives (SSD) and flash drives.
Does Not Have a Touch Sensitive Screen
The ThinkPad E540 does not have a touch sensitive screen, although this is within the context that most of the other many processor core portable PCs that have been available for a comparable time to the ThinkPad E540 also do not have a touch sensitive screen.
Quite Small Hybrid Hard Drive (H-HDD) Capacity
At only 500 gigabytes, the ThinkPad E540 has a quite small hybrid hard drive (H-HDD) capacity compared to most of the other portable PCs of this age and type. Portable PCs of a comparable type and age to the ThinkPad E540 have hybrid hard drive (H-HDD) capacities of between 8GB and 1TB.
6 Other reasons to consider the Lenovo ThinkPad E540
