This personal computer received a score of 80 out of 100 from personal computer expert review site parentesis.com.
HP Desktop Computers Have Good Reviews
PCs produced by HP have an average rating of 83%, which is in the top 25% of all personal computer brands that we have analysed.
64-Bit Processor Operating Mode
This PC supports a 64-bit processor operating mode, which is typical of many PCs of this type and age.
Quite Fast Processor Clock Speed
The processor clock speeds of computers of a comparable age and type to the Z420 range from 2.1GHz to 3.5GHz. With a processor clock speed of 3.5 gigahertz, the HP Z420 has a fairly fast processor clock speed compared to most of the other desktop computers of a comparable type and age to the Z420.
The HP Z420 is a four DisplayPort desktop computer.
Three 5.25" Bays
The HP Z420 is a three 5.25" bay PC. Most of the other many processor core PCs that came out more than a year ago only have between one and two 5.25" bays.
+5 More reasons for
Quite Fast Maximum Turbo Frequency
Personal computers of a similar age and type to the Z420 have maximum turbo frequencies of between 2.6GHz and 3.9GHz. At 3.9 gigahertz, the HP Z420 has a fairly fast maximum turbo frequency compared to most of the other computers of this age and spec.
Has One Memory Slot
The number of memory slots found on the HP Z420 is more than most computers of a comparable type 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 8x DIMM are also found on this HP computer.
DVD Super Multi Optical Drive Type
The optical drive type of this desktop computer is DVD Super Multi, which is the most frequently found optical drive type on PCs that have been available for more than a year.
Supports One Case Placement
The number of placements supported by the HP Z420 is more than most desktop computers of this age and type. This computer supports a Vertical case placement, which is the most commonly supported case placement supported by desktop computers of this spec and age.
5 Reasons Against
Very Small Max Internal Memory Supported Processor
The HP Z420 has a quite small max internal memory supported processor (only 256 gigabytes) compared to most of the other PCs that are a comparable age to the Z420. The smallest max internal memory supported processor of PCs of a comparable type and age to the Z420 is 64GB and the biggest is 770GB.
Quite Small Internal Memory
Across all the computers that have been available for a comparable time to the Z420 the internal memory range from 4GB to 64GB. At only 8 gigabytes, the HP Z420 has a very small internal memory compared to most of the other desktop computers of a comparable age and type to the Z420.
It may also be worth considering one of the other 8GB memory computers currently available including cheaper personal computers such as the DELL Precision T5610 (£1,318.80).
If you are looking for a PC with a bigger internal memory then you might want to look at the HP Z640 (£1,954.84) (16GB) which is also cheaper.
Very Small L3 Cache
With a L3 cache of only 12 megabytes, the HP Z420 has one of the smaller L3 caches amongst PCs of this age. Comparable spec desktop computers that have been on the market for a similar time to the Z420 have L3 caches of between 10MB and 30MB, and the average L3 cache is 23MB.
Very Small Processor Cache
With a processor cache of only 12 megabytes, the HP Z420 has one of the smaller processor caches amongst many processor core PCs of this age. The smallest processor cache of many processor core PCs that were released around the same time as the Z420 is 12MB, the biggest is 30MB, and the average processor cache is 20MB.
+2 More reasons against
Very Small Maximum Internal Memory
At only 64 gigabytes, the HP Z420 has a fairly small maximum internal memory compared to most of the other comparable spec PCs that have been on the market for more than a year. Across all the desktop computers that were released one year ago the maximum internal memory range from 32GB to 520GB.
3 Other reasons to consider the HP Z420
Average Hard Drive Capacity
The HP Z420 has a fairly typical hard drive capacity (1,000 gigabyte) compared to most of the other comparable spec PCs that were released around the same time as the Z420.
Average Total Storage Capacity
At 1,000 gigabyte, the HP Z420 has a fairly average total storage capacity compared to most of the other many processor core PCs that were launched more than a year ago.
HDD Storage Medium
The HP Z420 has an HDD storage medium which is faster than most personal computers of this type and age. Most comparable spec personal computers that have been available for a similar time to it have an SSD storage medium. 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.
Other HDD personal computers currently available that you might also want to consider include cheaper computers such as the DELL Precision T5610 (£1,318.80).
If you want a personal computer with a faster storage speed then you might also want to look at the Lenovo P700 (£1,638.97) (SSD) which also has a higher rating.
