7 Reasons For

HP Has Good PC Reviews

HP has good average reviews for its many processor core personal computers as well as across its entire desktop computer range.

64-Bit Processor Operating Mode

This computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on similar spec PCs that came out more than two years ago.

Chart Edit

Very Fast Processor Clock Speed

The HP Z420 has a very fast processor clock speed (3.7 gigahertz) compared to most of the other PCs that have been around for around the same time as the Z420. Across all the many processor core personal computers that came out around the same time as the Z420 the processor clock speeds range from 1.6GHz to 3.7GHz.

Chart Edit

Very Fast Maximum Turbo Frequency

At 4 gigahertz, the HP Z420 has a very fast maximum turbo frequency compared to most of the other personal computers that have been on the market for more than two years. Across all the many processor core personal computers that were released more than two years ago the maximum turbo frequencies range from 2.5GHz to 4GHz, and the average maximum turbo frequency is 3.5GHz.

Chart Edit

Three 5.25" Bays

The HP Z420 is a three 5.25" bay PC. Most of the other many processor core personal computers that came out more than two years ago only have between one and two 5.25" bays.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP Z420 is more than most many processor core personal computers that have been on the market for around the same time as it. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this personal computer. The memory slots 8x DIMM are also found on this desktop computer.

Chart Edit

DVD Super Multi Optical Drive Type

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

Chart Edit

11 Reasons Against

Very Slow Memory Clock Speed Supported by Processor

At only 800 megahertz, the HP Z420 has a quite slow memory clock speed supported by processor compared to most of the other many processor core personal computers that are a comparable age to the Z420. The slowest memory clock speed supported by processor of PCs that have been available for a comparable time to the Z420 is 800MHz and the fastest is 1,600MHz.

Chart Edit

Very Small Total Storage Capacity

The average total storage capacity of desktop computers of a similar type and age to the Z420 is 800GB. With a total storage capacity of only 256 gigabytes, the HP Z420 has a fairly small total storage capacity compared to most of the other computers that are a comparable age to the Z420.

If you would prefer a bigger total storage capacity then you might want to consider the DELL Precision T5610[plb_3364976_price] (500GB).

Only Four USB 3.0 (3.1 Gen 1) Type-A Ports

The HP Z420 is a four USB 3.0 (3.1 Gen 1) Type-A port PC.

Chart Edit

Very Small Max Internal Memory Supported Processor

The max internal memory supported processors of desktop computers that have been around for around the same time as the Z420 range from 64GB to 770GB, and the average max internal memory supported processor is 630GB. The HP Z420 has one of the smaller max internal memory supported processors (only 256 gigabytes) amongst many processor core personal computers of this age.

Chart Edit

Only One CPU Configuration (max)

Most comparable spec desktop computers that have been available 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

Across all the desktop computers of this spec and age the memory clock speeds range from 1,300MHz to 2,200MHz, and the average memory clock speed is 1,900MHz. With a memory clock speed of only 1,866 megahertz, the HP Z420 has a fairly slow memory clock speed compared to most of the other PCs of this age and spec.

Chart Edit

Only Four USB 3.0 Ports

The HP Z420 is a four USB 3.0 port desktop computer.

Chart Edit

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

The HP Z420 is a two PCI Express x16 (Gen 3.x) slot desktop computer.

Chart Edit

Quite Small Maximum Internal Memory

When compared to other PCs of this spec and age that we have assessed, the maximum internal memory of the HP Z420 of only 64 gigabytes is one of the smallest. The maximum internal memory of many processor core personal computers that were released more than two years ago range from 32GB to 520GB, and the average maximum internal memory is 140GB.

Chart Edit

Only One Ethernet LAN (RJ-45) Port

The HP Z420 is a one Ethernet LAN (RJ-45) port PC. Most of the other many processor core personal computers that were launched more than two years ago have one Ethernet LAN (RJ-45) port.

Chart Edit

Only 12 Processor Threads

The HP Z420 is a 12 processor thread personal computer. Most of the other many processor core personal computers that have been around for more than two years have between 6 and 23 processor threads.

Chart Edit

3 Other reasons to consider the HP Z420

Released Over Two Years Ago

This PC has been on the market for over two years.

Average Internal Memory

At 16 gigabytes, the HP Z420 has a relatively average internal memory compared to most of the other many processor core personal computers that came out around the same time as the Z420.

Chart Edit

SSD Storage Medium

The storage speed of this computer is SSD, which is the most frequently found storage medium on many processor core personal computers that have been available for around the same time as it. 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.
