Review  HP Workstation Z420

4 Reasons For

64-Bit Processor Operating Modes

This PC supports a 64-bit processor operating modes, which is typical of many many processor cores desktop computers that have been around for around the same time as it.

Chart Edit

Good Brand

Based on 322 user and expert reviews, HP has good ratings for its desktop computers. HP also has good ratings specifically for its many processor cores desktop computers.

Three Number of 5.25" Bayss

The HP Z420 is a three number of 5.25" bays PC. Most of the other many processor cores desktop computers that were released more than a year ago have between one and three number of 5.25" bayss.

Chart Edit

Has One Memory Slots

The HP Z420 has a greater number of memory slots than most desktop computers of this spec and age. This personal computer has an 8x DIMM memory slots, which is the most frequently found memory slots found on computers of this type and age.

Chart Edit

10 Reasons Against

Very Slow Memory Clock Speeds Supported by Processor

The memory clock speeds supported by processors of PCs that are a comparable age to the Z420 range from 800MHz to 1,600MHz, and the average memory clock speeds supported by processor is 1,400MHz. With a memory clock speeds supported by processor of only 800 megahertz, the HP Z420 has one of the slower memory clock speeds supported by processors amongst many processor cores desktop computers of this age.

Chart Edit

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

The HP Z420 is a four USB 3.0 (3.1 Gen 1) Type-A ports quantity personal computer. Most of the other PCs of this type and age have between two and seven USB 3.0 (3.1 Gen 1) Type-A ports quantitys.

Chart Edit

Very Slow Memory Bandwidth Supported by Processor (max)

The HP Z420 has one of the slower memory bandwidth supported by processor (max)s (only 51.2 gigabytes per second) amongst comparable spec personal computers of this age. The slowest memory bandwidth supported by processor (max) of many processor cores desktop computers that came out more than a year ago is 51GB/s and the fastest is 68GB/s.

Chart Edit

Quite Small Maximum Internal Memory Supported by Processor

With a maximum internal memory supported by processor of only 375 gigabytes, the HP Z420 has one of the smaller maximum internal memory supported by processors amongst many processor cores desktop computers of this age. Across all the computers of this age and type the maximum internal memory supported by processors range from 64GB to 770GB.

Chart Edit

Very Small Internal Memory

Desktop computers of this age and type have internal memorys of between 4GB and 64GB, and the average internal memory is 16GB. With an internal memory of only 8 gigabytes, the HP Z420 has one of the smaller internal memorys amongst PCs of this age.

If this computer internal memory is not big enough for you then you might also want to look at the HP 840[plb_3096344_price] (16GB) which is also higher rated.

Only One CPU Configuration (max)

The HP Z420 is a personal computer that takes one CPU configuration (max)s.

Chart Edit

Quite Slow Memory Clock Speed

With a memory clock speed of only 1,600 megahertz, the HP Z420's memory clock speed is one of the slowest amongst many processor cores desktop computers that have been available for around the same time as the Z420. The average memory clock speed of many processor cores desktop computers that were launched around the same time as the Z420 is 2,100MHz.

Chart Edit

Very Small Processor Cache

The smallest processor cache of many processor cores desktop computers that have been available for a similar time to the Z420 is 12MB, the biggest is 30MB, and the average processor cache is 16MB. At only 12 megabytes, the HP Z420 has a quite small processor cache compared to most of the other personal computers that were released one year ago.

Chart Edit

Only One Ethernet LAN (RJ-45) Ports

The HP Z420 is a one ethernet LAN (RJ-45) ports desktop computer.

Chart Edit

Very Small Maximum Internal Memory

The average maximum internal memory of many processor cores desktop computers that have been around for more than a year is 200GB. The HP Z420 has one of the smaller maximum internal memorys (only 64 gigabytes) amongst comparable spec computers of this age.

Chart Edit

2 Other reasons to consider the HP Z420

Average Processor Frequency

The HP Z420 has a relatively standard processor frequency (3.2 gigahertz) compared to most of the other many processor cores desktop computers that have been around for a similar time to the Z420.

Personal computers with a faster processor frequency that might also be worth looking at include the HP 440[plb_3066153_price] (3.5GHz) which also has a higher rating.
