Review  HP Workstation Z420

6 Reasons For

64-Bit Processor Operating Modes

This computer supports a 64-bit processor operating modes, which is typical of many PCs of this type and age.

Chart Edit

Good Brand

Many processor cores desktop computers manufactured by HP have good reviews on average compared to other brands. We also checked the reviews for all desktop computers (not just many processor cores desktop computers) and found that HP also has good reviews across its entire range.

Fairly Fast Processor Frequency

The average processor frequency of many processor cores desktop computers that have been available for around the same time as the Z420 is 2.9GHz, and the processor frequencys range from 1.6GHz to 3.7GHz. At 3.5 gigahertz, the HP Z420 has a fairly fast processor frequency compared to most of the other desktop computers of this spec and age.

Chart Edit

Very Fast Processor Boost Frequency

With a processor boost frequency of 3.9 gigahertz, the HP Z420 has one of the fastest processor boost frequencys amongst comparable spec PCs of this age. The average processor boost frequency of many processor cores desktop computers that were released more than two years ago is 3.5GHz.

Chart Edit

Has One Memory Slots

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

Chart Edit

DVD Super Multi Optical Drive Type

The optical drive type of this computer is DVD Super Multi, which is the most commonly found optical drive type on personal computers that have been on the market for around the same time as it.

Chart Edit

12 Reasons Against

Quite Slow Memory Clock Speeds Supported by Processor

When compared to other many processor cores desktop computers that have been available for a comparable time to the Z420, the memory clock speeds supported by processor of the HP Z420 of only 800 megahertz is one of the slowest. The memory clock speeds supported by processors of desktop computers that were released more than two years ago range from 800MHz to 1,600MHz, and the average memory clock speeds supported by processor is 1,100MHz.

Chart Edit

Only HDD Storage Media

The HP Z420 has an HDD storage media which is faster than the Flash storage media found on most many processor cores desktop computers that are a comparable age to it. 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.

An HDD storage media is actually the worst storage speed amongst all desktop computers of a similar age and spec to the Z420.

Amongst similar types of personal computer the best storage speed is SSD.

Quite Small Internal Memory

The smallest internal memory of desktop computers of a similar type and age to the Z420 is 4GB, the biggest is 64GB, and the average internal memory is 25GB. With an internal memory of only 4 gigabytes, the HP Z420 has one of the smallest internal memorys amongst many processor cores desktop computers of this age.

Chart Edit

Very Small Hard Drive Capacity

At only 500 gigabytes, the HP Z420 has a quite small hard drive capacity compared to most of the other many processor cores desktop computers that came out around the same time as the Z420. The hard drive capacitys of many processor cores desktop computers that have been available for a comparable time to the Z420 range from 500GB to 2TB.

Chart Edit

Very Small Maximum Internal Memory Supported by Processor

The HP Z420 has a quite small maximum internal memory supported by processor (only 256 gigabytes) compared to most of the other comparable spec PCs that were launched around the same time as the Z420. The average maximum internal memory supported by processor of many processor cores desktop computers that are a similar age to the Z420 is 610GB.

Chart Edit

Only One CPU Configuration (max)

Most many processor cores desktop computers that have been around for a similar time to the Z420 take one CPU configuration (max), including the HP Z420 which takes one CPU configuration (max).

Chart Edit

Quite Slow Memory Clock Speed

The HP Z420 has a fairly slow memory clock speed (only 1,866 megahertz) compared to most of the other comparable spec desktop computers that were launched more than two years ago. Many processor cores desktop computers that are a comparable age to the Z420 have memory clock speeds of between 1,300MHz and 2,200MHz, and the average memory clock speed is 1,900MHz.

Chart Edit

Only Two PCI Express X16 (Gen 3.x) Slotss

The HP Z420 is a two PCI Express x16 (Gen 3.x) slots PC.

Chart Edit

Very Small Processor Cache

The processor caches of comparable spec personal computers that have been around for a similar time to the Z420 range from 12MB to 30MB. The HP Z420 has one of the smaller processor caches (only 12 megabytes) amongst comparable spec computers of this age.

Chart Edit

Only One Ethernet LAN (RJ-45) Ports

Most many processor cores desktop computers that have been available for more than two years have between one and two ethernet LAN (RJ-45) portss, including the HP Z420 which has one ethernet LAN (RJ-45) ports.

Chart Edit

Very Small Maximum Internal Memory

The HP Z420 has one of the smaller maximum internal memorys (only 64 gigabytes) amongst many processor cores desktop computers of this age. PCs of a comparable spec and age to the Z420 have maximum internal memorys of between 32GB and 520GB, and the average maximum internal memory is 120GB.

Chart Edit

Only 12 Processor Threadss

Most personal computers of a similar spec and age to the Z420 have between 6 and 23 processor threadss, including the HP Z420 which has 12 processor threadss.

Chart Edit

2 Other reasons to consider the HP Z420

Released Over Two Years Ago

It was over two years ago when HP released the Z420.

Average Total Storage Capacity

At 500 gigabytes, the HP Z420 has a fairly typical total storage capacity compared to most of the other similar spec PCs that have been on the market for a comparable time to the Z420.

Computers with a bigger total storage capacity that might be worth looking at include the Apple ME253[plb_3040913_price] (512GB).
