HP Z840 Workstation UNBOXING Windows 7 Professional
Review of the HP Z840 Workstation, Z27s Display & Quadro M6000

10 Reasons For

HP Has Good PC Reviews

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

64-Bit Processor Operating Mode

This PC supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on similar spec computers that have been on the market for around the same time as it.

Chart Edit

Two CPUs Configuration (max)

Most of the other desktop computers that have been on the market for a comparable time to the Z840 only take one CPU configuration (max), however the HP Z840 takes two CPUs configuration (max).

Chart Edit

Very Fast Memory Clock Speed Supported by Processor

Across all the many processor core personal computers that came out around the same time as the Z840 the memory clock speeds supported by processors range from 800MHz to 1,600MHz. With a memory clock speed supported by processor of 1,600 megahertz, the HP Z840 has a very fast memory clock speed supported by processor compared to most of the other PCs that have been available for around the same time as the Z840.

Chart Edit

Quite Big Total Storage Capacity

Many processor core personal computers that have been on the market for a similar time to the Z840 have total storage capacity of between 120GB and 2.3TB. At 2,000 gigabytes, the HP Z840 has a fairly big total storage capacity compared to most of the other many processor core personal computers that have been available for around the same time as the Z840.

Chart Edit

Very Fast Memory Clock Speed

When compared to other comparable spec personal computers that were launched more than a year ago, the HP Z840's memory clock speed of 2,133 megahertz is one of the fastest. The slowest memory clock speed of many processor core personal computers that were launched around the same time as the Z840 is 1,600MHz, the fastest is 2,200MHz, and the average memory clock speed is 2,000MHz.

Chart Edit

Very Big Maximum Internal Memory

With a maximum internal memory of 512 gigabytes, the HP Z840's maximum internal memory is one of the biggest amongst desktop computers of this age and type. The maximum internal memory of desktop computers of this age and spec range from 32GB to 520GB.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z840 has a DDR4-SDRAM internal memory type which is newer than most desktop computers of this spec and age. Most similar spec PCs that were released around the same time as it have a DDR3-SDRAM internal memory type.

This desktop computer's internal memory type (DDR4-SDRAM) is actually the best internal memory type across all comparable spec PCs that have been around for around the same time as the Z840.

The worst internal memory type amongst similar types of desktop computer is DDR3-SDRAM.

Four 3.5" Bays

Most many processor core personal computers that are a comparable age to the Z840 have between two and nine 3.5" bays, including the HP Z840 which has four 3.5" bays.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP Z840 is more than most many processor core personal computers that have been available for around the same time as it. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this computer. The memory slots 8x DIMM are also found on this personal computer.

Chart Edit

8 Reasons Against

Quite Slow Processor Clock Speed

At only 2.4 gigahertz, the HP Z840 has a fairly slow processor clock speed compared to most of the other similar spec PCs that were launched around the same time as the Z840. Many processor core personal computers that were released around the same time as the Z840 have processor clock speeds of between 1.6GHz and 3.5GHz.

Chart Edit

Only HDD Storage Medium

The HP Z840 has an HDD storage medium which is faster than most many processor core personal computers that were launched more than a year ago. Most personal computers that have been available 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.

This personal computer's storage speed (HDD) is actually the worst storage speed amongst all many processor core personal computers that were released around the same time as the Z840.

The best storage speed amongst comparable types of personal computer is SSD.

Read more Less Chart Edit

Only Two USB 2.0 Ports

The HP Z840 is a two USB 2.0 port computer.

Chart Edit

Very Small Internal Memory

The internal memory of personal computers of a comparable age and spec to the Z840 range from 8GB to 64GB, and the average internal memory is 24GB. The HP Z840 has a fairly small internal memory (only 8 gigabytes) compared to most of the other computers of this spec and age.

Chart Edit

Quite Slow Max Memory Bandwidth Supported Processor

The HP Z840 has one of the slower max memory bandwidth supported processor (only 59 gigabytes per second) amongst similar spec desktop computers of this age. Many processor core personal computers that came out more than a year ago have max memory bandwidth supported processor of between 51GB/s and 68GB/s.

Chart Edit

Quite Slow Maximum Turbo Frequency

The HP Z840 has a fairly slow maximum turbo frequency (only 3.2 gigahertz) compared to most of the other PCs of a similar spec and age to the Z840. The slowest maximum turbo frequency of personal computers that have been available for a similar time to the Z840 is 2.6GHz, the fastest is 3.9GHz, and the average maximum turbo frequency is 3.6GHz.

Chart Edit

Only One Ethernet LAN (RJ-45) Port

The HP Z840 is a one Ethernet LAN (RJ-45) port desktop computer. Most of the other computers of this type and age have one Ethernet LAN (RJ-45) port.

Chart Edit

Heavy

The lightest many processor core personal computer that is a similar age to the Z840 is 5kg heavy, the heaviest is 30kg, and the average weight is 11kg. The HP Z840 is fairly heavy (21.1 kilograms) compared to most of the other PCs that have been on the market for more than a year.
