6 Reasons For

HP Has Good PC Reviews

Many processor core personal computers produced by HP have good ratings on average compared to other brands. We also checked the reviews for all PCs (not just many processor core personal computers) and found that HP also has good ratings across its entire 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 many processor core personal computers that have been available for more than two years.

Chart Edit

Quite Fast Processor Clock Speed

At 3.5 gigahertz, the HP Z420 has a quite fast processor clock speed compared to most of the other computers of a similar type and age to the Z420. The slowest processor clock speed of many processor core personal computers that have been around for a similar time to the Z420 is 1.6GHz and the fastest is 3.7GHz.

Chart Edit

Quite Fast Maximum Turbo Frequency

The HP Z420 has one of the faster maximum turbo frequencies (3.9 gigahertz) amongst PCs of this age. Personal computers that have been around for more than two years have maximum turbo frequencies of between 2.5GHz and 4GHz.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP Z420 is more than most desktop computers of a similar type and age to it. The most frequently found memory slot is 4x DIMM, but this memory slot is not found on this HP 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 personal computer is DVD Super Multi, which is typical of many computers that have been available for more than two years.

14 Reasons Against

Very Slow Memory Clock Speed Supported by Processor

Across all the comparable spec personal computers that were launched more than two years ago the memory clock speeds supported by processors range from 800MHz to 1,600MHz, and the average memory clock speed supported by processor is 1,100MHz. At only 800 megahertz, the HP Z420 has a fairly slow memory clock speed supported by processor compared to most of the other computers of a comparable spec and age to the Z420.

Chart Edit

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 personal computer.

Chart Edit

Quite Small Internal Memory

At only 4 gigabytes, the HP Z420 has a quite small internal memory compared to most of the other PCs of this age and type. Across all the desktop computers of this spec and age the internal memory range from 4GB to 64GB, and the average internal memory is 22GB.

Personal computers with a bigger internal memory that might also be worth looking at include the HP Z440 (8GB).

Quite Small Hard Drive Capacity

At only 500 gigabytes, the HP Z420 has a quite small hard drive capacity compared to most of the other computers of this age and spec. Many processor core personal computers that were released more than two years ago have hard drive capacity of between 500GB and 2TB, and the average hard drive capacity is 1.1TB.

PCs with a bigger hard drive capacity that might be worth considering include the Z440 (1TB), or the Z440 (1TB) both from HP.

Very Small Max Internal Memory Supported Processor

Across all the many processor core personal computers that were launched around the same time as the Z420 the max internal memory supported processors range from 64GB to 770GB, and the average max internal memory supported processor is 630GB. At only 256 gigabytes, the HP Z420 has a fairly small max internal memory supported processor compared to most of the other similar spec computers that have been on the market for a comparable time to the Z420.

Chart Edit

Only One CPU Configuration (max)

The HP Z420 is a PC that takes one CPUs configuration (max).

Chart Edit

Quite Slow Memory Clock Speed

Across all the personal computers that have been available for a similar time to the Z420 the memory clock speeds range from 1,300MHz to 2,200MHz. The HP Z420 has one of the slower memory clock speeds (only 1,866 megahertz) amongst many processor core personal computers of this age.

Chart Edit

Only Four USB 3.0 Ports

The HP Z420 is a four USB 3.0 port PC. Most of the other personal computers of this age and spec have between two and eight USB 3.0 ports.

Chart Edit

Only Three 3.5" Bays

Most many processor core personal computers that have been available for around the same time as the Z420 have between two and five 3.5" bays, including the HP Z420 which has three 3.5" bays.

Chart Edit

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

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

Chart Edit

Quite Small Processor Cache

Across all the PCs of a comparable age and spec to the Z420 the processor caches range from 12MB to 30MB, and the average processor cache is 20MB. When compared to other similar spec PCs that were released more than two years ago that we have checked the processor cache of, the HP Z420's processor cache of only 12 megabytes is one of the smallest.

Chart Edit

Very Small Maximum Internal Memory

The HP Z420 has one of the smaller maximum internal memory (only 64 gigabytes) amongst many processor core personal computers of this age. Desktop computers of a comparable spec and age to the Z420 have maximum internal memory of between 32GB and 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 computer. Most of the other PCs of this age and spec have one Ethernet LAN (RJ-45) port.

Chart Edit

Only 12 Processor Threads

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

3 Other reasons to consider the HP Z420

Released Over Two Years Ago

This computer was released over two years ago.

Average Total Storage Capacity

At 500 gigabytes, the HP Z420 has a fairly standard total storage capacity compared to most of the other desktop computers that are a similar age to the Z420.

Chart Edit

HDD Storage Medium

The HP Z420 has a faster storage speed than most PCs of this age and spec. This PC has an HDD storage medium, whereas most personal computers that have been on the market for around the same time as it have a Flash 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.
