This notebook PC supports a 64-bit processor operating mode, which is the most commonly supported processor operating mode on similar spec notebook PCs that have been available for a comparable time to it.
Three USB 3.0 (3.1 Gen 1) Type-A Ports
Most many processor core laptops that were launched around the same time as the ZBook 15 have between one and four USB 3.0 (3.1 Gen 1) Type-A ports, including the HP ZBook 15 which has three USB 3.0 (3.1 Gen 1) Type-A ports.
1920 X 1080 Pixels Display Resolution
The ZBook 15 has a maximum display resolution of 1920 x 1080 pixels. That's 98% more display resolution than the most frequently found display resolution of 1366 x 768 pixels.
This laptop's display resolution (1920 x 1080 pixels) is in fact the best display resolution amongst all notebook PCs of a similar type and age to the ZBook 15.
A 1366 x 768 pixels display resolution is the worst display resolution amongst comparable types of laptop.
We compared all the other notebook PCs that have a display resolution of 1920 x 1080 pixels to this portable PC and we think the N56VJ, and the U500VZ (£649.99) both from Asus which has a better Rating is also worth considering.
Fairly Big Internal Memory
The ZBook 15 has one of the bigger internal memory (16 gigabytes) amongst many processor core laptops of this age. Many processor core laptops that came out around the same time as the ZBook 15 have internal memory of between 2GB and 32GB.
+17 More reasons for
Very Fast Processor Clock Speed
The processor clock speeds of similar spec laptops that are a comparable age to the ZBook 15 range from 1GHz to 3.1GHz, and the average processor clock speed is 2.2GHz. When compared to other many processor core laptops that have been available for a comparable time to the ZBook 15 that we have assessed, the processor clock speed of the ZBook 15 of 2.8 gigahertz is one of the fastest.
Intel Core I7 Processor Family
This portable PC has an Intel Core i7-4xxx processor family, which is the most frequently found processor family on many processor core laptops that were released more than two years ago.
Has a Front Camera
The HP ZBook 15 has a front camera, as do most of the other many processor core laptops that have been available for more than two years.
1,600MHz Processor Memory Clock Speed
The ZBook 15 supports a faster memory clock speeds supported by processor than most notebook PCs that have been available for a comparable time to it. This laptop supports a 1,600MHz processor memory clock speed, whereas most portable PCs of this spec and age support a 133MHz processor memory clock speed.
A 1,600MHz processor memory clock speed is in fact the best supported memory clock speeds supported by processor amongst all portable PCs of a comparable type and age to the ZBook 15.
A 133MHz processor memory clock speed is the worst supported memory clock speeds supported by processor across comparable types of laptop.
SSD Storage Medium
The ZBook 15 has an SSD storage medium which is better than the HDD storage medium found on most many processor core laptops that have been on the market for more than two years. 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.
This portable PC's storage medium (SSD) is actually the best storage medium amongst all many processor core laptops that have been available for a similar time to the ZBook 15.
Amongst similar types of portable PC the worst storage medium is HDD.
64-Bit Operating System Architecture
This notebook PC has a 64-bit operating system architecture, which is typical of many portable PCs of this spec and age.
4x SO-DIMM Memory Slot
The biggest memory slots of the ZBook 15 is 4x SO-DIMM. That's over two times the memory slots of the most common memory slot of 2x SO-DIMM.
A 4x SO-DIMM memory slot is in fact the best memory slots across all notebook PCs of this age and type.
Across similar types of laptop the worst memory slots is 1x SO-DIMM.
Very Big Processor Cache
Laptops of a similar age and spec to the ZBook 15 have processor caches of between 2MB and 8MB, and the average processor cache is 4.6MB. The ZBook 15 has a very big processor cache (8 megabytes) compared to most of the other laptops that have been available for a similar time to the ZBook 15.
L3 Processor Cache
This portable PC has a L3 processor cache, which is the most frequently found processor cache on many processor core laptops that have been available for more than two years.
Fairly Big Maximum Internal Memory
With a maximum internal memory of 32 gigabytes, the ZBook 15 has a fairly big maximum internal memory compared to most of the other notebook PCs of a similar age and type to the ZBook 15. Portable PCs that have been available for around the same time as the ZBook 15 have maximum internal memory of between 2GB and 32GB.
Eight Processor Threads
The ZBook 15 is a eight processor thread laptop. Most of the other notebook PCs of this age and type only have between four and seven processor threads.
Very Fast Maximum Turbo Frequency
The average maximum turbo frequency of many processor core laptops that are a comparable age to the ZBook 15 is 3.2GHz. When compared to other many processor core laptops that were released more than two years ago, the maximum turbo frequency of the HP ZBook 15 of 3.8 gigahertz is one of the fastest.
Eight Battery Cells
The HP ZBook 15 is a eight battery cell count laptop. Most of the other notebook PCs that have been available for more than two years have between two and eight battery cells.
Quite Big Battery Capacity
With a battery capacity of 83 watt-hours, the ZBook 15 has a quite big battery capacity compared to most of the other portable PCs of this age and spec. Portable PCs that are a comparable age to the ZBook 15 have battery capacities of between 30Wh and 100Wh.
802.11g WiFi Standard
The ZBook 15 has an 802.11g WiFi standard which is better than the 802.11b WiFi standard found on most notebook PCs of a similar age and type to it. The worst Wi-Fi standard of all laptops of this age and type is 802.11a and the best is 802.11n.
GDDR Discrete Graphics Memory Type
This portable PC has a GDDR5 discrete graphics memory type, which is typical of many notebook PCs of this type and age.
4 Reasons Against
Does Not Have a Full-Size Keyboard
The ZBook 15 does not have a full-size keyboard, unlike most of the other portable PCs of a similar age and type to the ZBook 15.
We compared this notebook PC to all the other portable PCs with a full-size keyboard and we think the Asus U500VZ (£649.99) which is also higher rated is also worth considering.
Very Small Total Storage Capacity
The ZBook 15 has a fairly small total storage capacity (only 256 gigabytes) compared to most of the other laptops of a comparable age and type to the ZBook 15. The average total storage capacity of portable PCs of a comparable type and age to the ZBook 15 is 660GB.
Does Not Have a Touch Sensitive Screen
Like most of the other portable PCs that are a comparable age to the ZBook 15, the HP ZBook 15 does not have a touch sensitive screen.
The average weight of portable PCs of this spec and age is 2.5kg. With a weight of 2.8 kilograms, the ZBook 15 is fairly heavy compared to most of the other laptops of this spec and age.
