The slowest on-board graphics adapter dynamic frequency of portable PCs of a comparable type and age to the BU401LA is 750MHz and the fastest is 1,300MHz.
+12 More reasons for
Intel Core I7 Processor Family
The BU401LA has an Intel Core i7 processor family which is better than most laptops that have been around for a comparable time to it. Most comparable spec notebook PCs that have been on the market for a similar time to it have an Intel Core i5-5xxx processor family. Medium processor core laptops that came out around the same time as the BU401LA processor families range from AMD E to Intel Core i7-3xxx.
It may also be worth considering one of the alternative laptops that have an Intel Core i7-4xxx processor family currently available including because of it's better review score, the DELL XPS 13, the Samsung ATIV Book 9, or the Asus BU201LA.
If you would prefer a notebook PC with a better processor family then you might also want to consider the Lenovo IdeaPad Z580 (£1,399.98) (Intel Core i7-3xxx).
1,600MHz Processor Memory Clock Speed
The Asus BU401LA supports a 1,600MHz processor memory clock speed which is faster than most laptops that were released more than a year ago. Most medium processor core laptops that were released one year ago support a 133MHz processor memory clock speed.
This portable PC's memory clock speeds supported by processor (1,600MHz) is actually the best supported memory clock speeds supported by processor across all similar spec notebook PCs that came out more than a year ago.
The worst supported memory clock speeds supported by processor amongst similar types of portable PC is 133MHz.
SSD Storage Medium
The Asus BU401LA has a better storage medium than most medium processor core laptops that came out around the same time as it. This notebook PC has an SSD storage medium, whereas most comparable spec portable PCs that are a similar age to it have an HDD storage medium. Solid State Drives (SSD) store data in semiconductors on a circuit board rather than using magnetic or optical media. Solid State Drives have no moving parts which makes them very fast and reliable.
An SSD storage medium is actually the best storage medium amongst all similar spec notebook PCs that have been around for more than a year.
An HDD storage medium is the worst storage medium across similar types of laptop.
We compared all the other laptops that have an SSD storage media to this notebook PC and we think the DELL XPS 13 9343 which has a better Rating is also worth considering.
Has a Front Camera
The BU401LA has a front camera, as do most of the other medium processor core laptops that are a similar age to the BU401LA.
We compared this laptop to all the other notebook PCs with a front camera and we think the XPS 13 9343, and the Latitude 14 E7450 both from DELL which has a better Rating is also worth considering.
Fairly Fast Maximum Turbo Frequency
The average maximum turbo frequency of portable PCs of a similar type and age to the BU401LA is 2.9GHz. At 3.3 gigahertz, the Asus BU401LA has a quite fast maximum turbo frequency compared to most of the other comparable spec notebook PCs that have been on the market for around the same time as the BU401LA.
L3 Processor Cache
This laptop has a L3 processor cache, which is the most commonly found processor cache on portable PCs of a similar age and spec to it.
Fairly Big Battery Capacity
The Asus BU401LA has one of the bigger battery capacities (6,840 milliamperes * hour) amongst comparable spec laptops of this age. The smallest battery capacity of medium processor core laptops that are a similar age to the BU401LA is 37mAh and the biggest is 9,300mAh.
256 Solid-State Drive Capacity
The BU401LA is a 256 gigabytes solid-state drive capacity notebook PC.
802.11g WiFi Standard
The BU401LA has a better Wi-Fi standard than most laptops that were launched more than a year ago. This laptop has an 802.11g WiFi standard, whereas most laptops that were launched around the same time as it have an 802.11n WiFi standard. Across all medium processor core laptops that came out around the same time as the BU401LA the best Wi-Fi standard is 802.11n and the worst is 802.11ad.
Quite Big Processor Cache
Across all the portable PCs of this age and spec the processor caches range from 1MB to 6MB. At 4 megabytes, the BU401LA has a quite big processor cache compared to most of the other portable PCs of a comparable age and spec to the BU401LA.
Quite Big Battery Capacity
The smallest battery capacity of laptops that were launched around the same time as the BU401LA is 23Wh, the biggest is 120Wh, and the average battery capacity is 47Wh. The Asus BU401LA has one of the bigger battery capacities (53 watt-hours) amongst medium processor core laptops of this age.
8 Reasons Against
Quite Slow On-Board Graphics Adapter Base Frequency
With an on-board graphics adapter base frequency of only 200 megahertz, the Asus BU401LA has a quite slow on-board graphics adapter base frequency compared to most of the other medium processor core laptops that have been available for more than a year. The on-board graphics adapter base frequencies of laptops that were released around the same time as the BU401LA range from 100MHz to 650MHz, and the average on-board graphics adapter base frequency is 280MHz.
Does Not Have a Full-Size Keyboard
The Asus BU401LA does not have a full-size keyboard. Most of the other notebook PCs of a similar age and type to the BU401LA do have a full-size keyboard.
The Asus BU401LA has one of the smaller total storage capacity (only 256 gigabytes) amongst comparable spec notebook PCs of this age. Portable PCs of a similar type and age to the BU401LA have total storage capacity of between 32GB and 2TB.
There are a number of other 256GB total storage capacity laptops currently available that you might want to consider including the Samsung ATIV Book 9 which has a better Rating.
If this portable PC total storage capacity is too small for you then you might also want to consider the DELL Latitude 14 E7450 (500GB and higher rated).
Quite Slow Processor Clock Speed
The slowest processor clock speed of similar spec notebook PCs that were launched around the same time as the BU401LA is 0.8GHz and the fastest is 3.3GHz. With a processor clock speed of only 1.7 gigahertz, the Asus BU401LA has one of the slower processor clock speeds amongst medium processor core laptops of this age.
We compared this portable PC to all the other 1.7GHz processor clock speed notebook PCs and we think the DELL XPS 13 which has a better Rating is also worth considering.
If you would prefer a faster processor clock speed then you might want to look at the Fujitsu Lifebook U745 (£1,064.40) (2.2GHz) which also has a higher rating.
