This computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on personal computers of a comparable age and type to it.

Chart Edit

Two CPUs Configuration (max)

Most of the other many processor core personal computers that have been available for a comparable time to the Z840 only take one CPU configuration (max), however the HP Z840 takes two CPUs configuration (max).

Chart Edit

Eight USB 3.0 (3.1 Gen 1) Type-A Ports

The HP Z840 is a eight USB 3.0 (3.1 Gen 1) Type-A port computer.

Chart Edit

Fairly Fast Max Memory Bandwidth Supported Processor

The HP Z840 has one of the faster max memory bandwidth supported processor (68 gigabytes per second) amongst comparable spec PCs of this age. The average max memory bandwidth supported processor of many processor core personal computers that are a similar age to the Z840 is 60GB/s.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

At 768 gigabytes, the HP Z840 has a quite big max internal memory supported processor compared to most of the other computers that came out around the same time as the Z840. The smallest max internal memory supported processor of desktop computers that have been around for around the same time as the Z840 is 64GB and the biggest is 770GB.

Chart Edit

Fairly Fast Memory Clock Speed Supported by Processor

The HP Z840 has one of the faster memory clock speeds supported by processors (1,600 megahertz) amongst many processor core personal computers of this age. Desktop computers of a comparable spec and age to the Z840 have memory clock speeds supported by processors of between 800MHz and 1,600MHz.

Chart Edit

24 Processor Threads

The HP Z840 has more processor threads than most of the PCs of a comparable age and spec to the Z840. Most of the many processor core personal computers that were released around the same time as the Z840 only have between 6 and 23 processor threads, however this computer has 24 processor threads.

Chart Edit

Very High System Bus Data Transfer Rate

At 9.6 Gigatransfers per second, the HP Z840 has a very high system bus data transfer rate compared to most of the other many processor core personal computers that are a similar age to the Z840. The average system bus data transfer rate of similar spec computers that have been on the market for around the same time as the Z840 is 8GT/s.

Chart Edit

Quite Big Processor Cache

Across all the personal computers that came out more than two years ago the processor caches range from 12MB to 30MB. At 30 megabytes, the HP Z840 has a fairly big processor cache compared to most of the other comparable spec PCs that have been on the market for around the same time as the Z840.

Chart Edit

Fairly Fast Memory Clock Speed

The average memory clock speed of desktop computers of a similar spec and age to the Z840 is 1,900MHz, and the memory clock speeds range from 1,300MHz to 2,200MHz. With a memory clock speed of 2,133 megahertz, the HP Z840 has a quite fast memory clock speed compared to most of the other comparable spec PCs that were released more than two years ago.

Chart Edit

Quite Big Maximum Internal Memory

Many processor core personal computers that are a similar age to the Z840 have maximum internal memory of between 32GB and 520GB, and the average maximum internal memory is 140GB. At 512 gigabytes, the HP Z840 has a fairly big maximum internal memory compared to most of the other many processor core personal computers that have been around for a similar time to the Z840.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z840 has a DDR4-SDRAM internal memory type which is newer than most many processor core personal computers that were launched around the same time as it. Most many processor core personal computers that were released more than two years ago have a DDR3-SDRAM internal memory type.

This desktop computer's internal memory type (DDR4-SDRAM) is actually the best internal memory type amongst all computers of a similar spec and age to the Z840.

A DDR3-SDRAM internal memory type is the worst internal memory type across comparable types of desktop computer.

Quite Big Solid-State Drive Capacity

The average solid-state drive capacity of desktop computers of a comparable age and type to the Z840 is 320GB, and the solid-state drive capacities range from 120GB to 1TB. At 512 gigabytes, the HP Z840 has a quite big solid-state drive capacity compared to most of the other comparable spec desktop computers that came out around the same time as the Z840.

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 more than two years. 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

DVD Super Multi Optical Drive Type

The optical drive type of this personal computer is DVD Super Multi, which is the most frequently found optical drive type on similar spec desktop computers that have been available for a comparable time to it.

Chart Edit

2 Reasons Against

Only One Ethernet LAN (RJ-45) Port

Most desktop computers that are a similar age to the Z840 have one Ethernet LAN (RJ-45) port, including the HP Z840 which has one Ethernet LAN (RJ-45) port.

Chart Edit

At 21.1 kilograms, the HP Z840 is quite heavy compared to most of the other PCs of this type and age. The weights of similar spec desktop computers that were released more than two years ago range from 250g to 30kg.

Chart Edit

5 Other reasons to consider the HP Z840

Released Over Two Years Ago

It was over two years ago when this personal computer was released.

Average Internal Memory

At 16 gigabytes, the HP Z840 has a pretty average internal memory compared to most of the other comparable spec desktop computers that have been around for a similar time to the Z840.

Chart Edit

SSD Storage Medium

The storage speed of this computer is SSD, which is the most commonly found storage medium on personal computers that are a comparable age to 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.

Chart Edit

Average Total Storage Capacity

At 512 gigabytes, the HP Z840 has a pretty average total storage capacity compared to most of the other PCs that were launched more than two years ago.

Chart Edit

Average Processor Clock Speed

At 2.5 gigahertz, the HP Z840 has a fairly standard processor clock speed compared to most of the other many processor core personal computers that came out more than two years ago.

If you want a faster processor clock speed then you might also want to consider the P900 (£3,366.71) (2.6GHz), or the P700 (2.6GHz) both from Lenovo.
