Review  HP Workstation Z420

12 Reasons For

HP Has Good PC Reviews

HP has good average ratings for its medium processor cores personal computers as well as across its entire personal computer range.

Fairly Fast Memory Bandwidth Supported by Processor (max)

The HP Z420 has one of the faster memory bandwidth supported by processor (max)s (59.7 gigabytes per second) amongst desktop computers of this age. Across all the PCs that have been on the market for around the same time as the Z420 the memory bandwidth supported by processor (max)s range from 10GB/s to 68GB/s.

Chart Edit

Quite Big Maximum Internal Memory Supported by Processor

The HP Z420 has one of the bigger maximum internal memory supported by processors (256 gigabytes) amongst similar spec PCs of this age. The average maximum internal memory supported by processor of medium processor cores personal computers that have been on the market for a comparable time to the Z420 is 90GB, and the maximum internal memory supported by processors range from 2GB to 770GB.

Chart Edit

Very Fast Processor Frequency

The processor frequency of the HP Z420 of 3.7 gigahertz is one of the fastest amongst PCs of this type and age. The average processor frequency of comparable spec computers that were released more than two years ago is 3.1GHz, and the processor frequencys range from 1GHz to 4.1GHz.

Chart Edit

SSD Storage Media

The HP Z420 has an SSD storage media which is faster than most medium processor cores personal computers that have been on the market for a similar time to it. Most comparable spec PCs that were released around the same time as it have an HDD storage media. Solid State Drives (SSD) store information in transistors on a circuit board rather than on optical or magnetic media. This has the advantage of being much faster than a traditional HDD drive.

An SSD storage media is actually the best storage speed amongst all medium processor cores personal computers that have been around for more than two years.

Amongst similar types of PC the worst storage speed is HDD.

3 PCI Express Slots Version

This personal computer supports a 3 PCI Express slots version, which is the most frequently supported PCI Express slots version on medium processor cores personal computers that were launched around the same time as it.

Chart Edit

Two PCI Express X16 Slotss

Most medium processor cores personal computers that have been available for a similar time to the Z420 have between one and two PCI Express x16 slotss, including the HP Z420 which has two PCI Express x16 slotss.

Chart Edit

Two Firewire (IEEE 1394) Portss

The HP Z420 is a two firewire (IEEE 1394) ports desktop computer. Most of the other similar spec computers that were released around the same time as the Z420 only have one firewire (IEEE 1394) ports.

Chart Edit

Very Big Processor Cache

The smallest processor cache of personal computers of this age and spec is 0.51MB, the biggest is 10MB, and the average processor cache is 6.9MB. When compared to other desktop computers of a comparable age and spec to the Z420, the processor cache of the HP Z420 of 10 megabytes is one of the biggest.

Chart Edit

Fairly Fast Processor Boost Frequency

Across all the medium processor cores personal computers that are a comparable age to the Z420 the processor boost frequencys range from 1.3GHz to 4.4GHz. The HP Z420 has one of the faster processor boost frequencys (3.9 gigahertz) amongst medium processor cores personal computers of this age.

Chart Edit

Has One Memory Slots

The number of memory slots found on the HP Z420 is more than most computers of a similar spec and age to it. The most commonly found memory slots is 4x DIMM, but this memory slots is not found on this desktop computer. The memory slotss 8x DIMM are also found on this HP desktop computer.

Chart Edit

Fairly Fast Memory Clock Speed

The memory clock speeds of personal computers of a similar age and spec to the Z420 range from 1,000MHz to 2,200MHz. The HP Z420 has a fairly fast memory clock speed (1,866 megahertz) compared to most of the other medium processor cores personal computers that have been available for a comparable time to the Z420.

Chart Edit

4 Reasons Against

Quite Slow Memory Clock Speeds Supported by Processor

The average memory clock speeds supported by processor of medium processor cores personal computers that have been available for a comparable time to the Z420 is 1,300MHz, and the memory clock speeds supported by processors range from 800MHz to 1,600MHz. With a memory clock speeds supported by processor of only 800 megahertz, the HP Z420 has a very slow memory clock speeds supported by processor compared to most of the other desktop computers of this age and spec.

Chart Edit

Very Small Total Storage Capacity

With a total storage capacity of only 240 gigabytes, the HP Z420 has a fairly small total storage capacity compared to most of the other computers that have been around for a comparable time to the Z420. The total storage capacitys of personal computers that were released more than two years ago range from 32GB to 3.3TB, and the average total storage capacity is 720GB.

Chart Edit

Only DVD Super Multi Optical Drive Type

The optical drive type of this desktop computer is DVD Super Multi, which is typical of many comparable spec personal computers that have been around for more than two years.

Chart Edit

Heavy

Across all the medium processor cores personal computers that have been on the market for a similar time to the Z420 the weights range from 250g to 24kg, and the average weight is 7.8kg. With a weight of 12.5 kilograms, the HP Z420 is quite heavy compared to most of the other comparable spec desktop computers that were released more than two years ago.

Chart Edit

2 Other reasons to consider the HP Z420

Released Over Two Years Ago

This desktop computer was released over two years ago.

Average Internal Memory

The HP Z420 has a pretty standard internal memory (8 gigabytes) compared to most of the other medium processor cores personal computers that have been available for a comparable time to the Z420.
