HP personal computers have an average rating of 83%, which is in the top 25% of all computer manufacturers that we have looked at.
64-Bit Processor Operating Mode
This desktop computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on many processor core PCs that have been available for more than a year.
Three 5.25" Bays
The HP Z420 has more 5.25" bays than most of the many processor core PCs that came out more than a year ago. This computer is a three 5.25" bay desktop computer compared to most of the desktop computers that have been around for around the same time as the Z420 which only have between one and two 5.25" bays.
Has One Memory Slot
The HP Z420 has a greater number of memory slots than most desktop computers of this spec and age. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this desktop computer. The memory slots 8x DIMM are also found on this personal computer.
Supports One Case Placement
The HP Z420 has a greater number of placements than most comparable spec PCs that were launched around the same time as it. This personal computer supports a Vertical case placement, which is the most commonly supported case placement supported by similar spec computers that are a comparable age to the Z420.
8 Reasons Against
Quite Slow Processor Clock Speed
The slowest processor clock speed of computers of a comparable type and age to the Z420 is 2.1GHz and the fastest is 3.5GHz. When compared to other desktop computers of this spec and age that we have checked, the processor clock speed of the HP Z420 of only 2.1 gigahertz is one of the slowest.
Quite Small Discrete Graphics Adapter Memory
The HP Z420 has a fairly small discrete graphics adapter memory (only 2,048 gigabytes) compared to most of the other desktop computers of this age and spec. The discrete graphics adapter memory capacities of desktop computers of a similar spec and age to the Z420 range from 2GB to 8.2TB, and the average discrete graphics adapter memory is 3.7TB.
Quite Slow Max Memory Bandwidth Supported Processor
The slowest max memory bandwidth supported processor of many processor core PCs that have been available for a similar time to the Z420 is 51GB/s, the fastest is 68GB/s, and the average max memory bandwidth supported processor is 61GB/s. At only 51.2 gigabytes per second, the HP Z420 has a quite slow max memory bandwidth supported processor compared to most of the other personal computers that were released around the same time as the Z420.
Quite Slow Maximum Turbo Frequency
Across all the many processor core PCs that were released around the same time as the Z420 the maximum turbo frequencies range from 2.6GHz to 3.9GHz, and the average maximum turbo frequency is 3.5GHz. At only 2.6 gigahertz, the HP Z420 has a very slow maximum turbo frequency compared to most of the other desktop computers that were released one year ago.
+5 More reasons against
Very Small Internal Memory
The average internal memory of similar spec PCs that have been around for around the same time as the Z420 is 23GB, and the internal memory range from 4GB to 64GB. With an internal memory of only 8 gigabytes, the HP Z420 has one of the smaller internal memory amongst PCs of this age.
If you are looking for a desktop computer with a bigger internal memory then you might want to consider the ME253 (£2,289.06) (12GB), or the ME253 (£2,046.55) (12GB) both from Apple.
Quite Small Discrete Graphics Adapter Memory
The average discrete graphics adapter memory of PCs that were released more than a year ago is 5.2GB, and the discrete graphics adapter memory range from 2GB to 8.2GB. At only 2,048 megabytes, the HP Z420 has a very small discrete graphics adapter memory compared to most of the other PCs that were released one year ago.
Very Low System Bus Data Transfer Rate
With a system bus data transfer rate of only 7.2 Gigatransfers per second, the HP Z420 has a quite low system bus data transfer rate compared to most of the other desktop computers that have been on the market for a comparable time to the Z420. Many processor core PCs that have been on the market for a similar time to the Z420 have system bus data transfer rates of between 7.2GT/s and 9.6GT/s, and the average system bus data transfer rate is 8.1GT/s.
Very Small L3 Cache
The L3 caches of desktop computers that are a similar age to the Z420 range from 10MB to 30MB. The HP Z420 has a fairly small L3 cache (only 10 megabytes) compared to most of the other many processor core PCs that have been on the market for around the same time as the Z420.
4 Other reasons to consider the HP Z420
Released Over a Year Ago
It was over a year ago when HP released the Z420.
Average Hard Drive Capacity
With a hard drive capacity of 1,000 gigabyte, the HP Z420 has a fairly typical hard drive capacity compared to most of the other desktop computers of this type and age.
Average Total Storage Capacity
With a total storage capacity of 1,000 gigabyte, the HP Z420 has a fairly average total storage capacity compared to most of the other many processor core PCs that have been available for more than a year.
It may also be worth also looking at one of the alternative 1TB total storage capacity computers currently available including because of it's better review score, the HP Z420 (£1,506.93).
+2 Other reasons
HDD Storage Medium
The HP Z420 has a faster storage speed than most PCs of this age and type. This personal computer has an HDD storage medium, whereas most many processor core PCs that have been available for a comparable 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.
