This computer supports a 64-bit processor operating mode, which is typical of many personal computers of a comparable age and spec to it.

Chart Edit

Two CPUs Configuration (max)

The HP Z840 takes more CPUs configuration (max) than most of the many processor core computers that were released around the same time as the Z840. This personal computer is a computer that takes two CPUs configuration (max) compared to most of the personal computers that were released more than two years ago which only take one CPU configuration (max).

Chart Edit

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

Most desktop computers of a comparable age and spec to the Z840 have between two and eight USB 3.0 (3.1 Gen 1) Type-A ports, including the HP Z840 which has eight USB 3.0 (3.1 Gen 1) Type-A ports.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

The HP Z840 has one of the bigger max internal memory supported processors (768 gigabytes) amongst many processor core computers of this age. Across all the personal computers of this age and type the max internal memory supported processors range from 64GB to 770GB.

Chart Edit

Quite Fast Memory Clock Speed Supported by Processor

At 1,600 megahertz, the HP Z840 has a fairly fast memory clock speed supported by processor compared to most of the other comparable spec personal computers that have been available for a similar time to the Z840. The memory clock speeds supported by processors of desktop computers that were released around the same time as the Z840 range from 800MHz to 1,600MHz, and the average memory clock speed supported by processor is 1,100MHz.

Chart Edit

Quite Big Total Storage Capacity

The HP Z840 has one of the bigger total storage capacity (1,000 gigabyte) amongst PCs of this age. Across all the comparable spec personal computers that have been around for more than two years the total storage capacity range from 180GB to 8.3TB.

Chart Edit

Very Fast Memory Clock Speed

The average memory clock speed of similar spec desktop computers that are a comparable age to the Z840 is 1,900MHz, and the memory clock speeds range from 1,300MHz to 2,200MHz. When compared to other PCs that have been available for around the same time as the Z840 that we have assessed, the memory clock speed of the HP Z840 of 2,133 megahertz is one of the fastest.

Chart Edit

Very Big Maximum Internal Memory

The maximum internal memory of computers of this age and spec range from 32GB to 520GB, and the average maximum internal memory is 140GB. When compared to other comparable spec desktop computers that came out around the same time as the Z840, the HP Z840's maximum internal memory of 512 gigabytes is one of the biggest.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z840 has a DDR4-SDRAM internal memory type which is newer than the DDR3-SDRAM internal memory type found on most computers of a comparable age and type to it.

This PC's internal memory type (DDR4-SDRAM) is actually the best internal memory type across all many processor core computers that were launched around the same time as the Z840.

A DDR3-SDRAM internal memory type is the worst internal memory type across similar types of PC.

Four 3.5" Bays

The HP Z840 is a four 3.5" bay desktop computer. Most of the other many processor core computers that are a similar age to the Z840 have between two and five 3.5" bays.

Chart Edit

Three PCI Express X16 (Gen 3.x) Slots

The HP Z840 is a three PCI Express x16 (Gen 3.x) slot PC.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP Z840 is more than most many processor core computers that are a similar age to 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 computer.

Chart Edit

DVD Super Multi Optical Drive Type

The optical drive type of this computer is DVD Super Multi, which is the most frequently found optical drive type on computers that are a comparable age to it.

Chart Edit

4 Reasons Against

Quite Slow Processor Clock Speed

With a processor clock speed of only 2.4 gigahertz, the HP Z840 has a fairly slow processor clock speed compared to most of the other many processor core computers that are a similar age to the Z840. The average processor clock speed of desktop computers of this age and type is 2.9GHz, and the processor clock speeds range from 1.6GHz to 3.7GHz.

Chart Edit

Only Two USB 2.0 Ports

Most PCs of this type and age have between two and nine USB 2.0 ports, including the HP Z840 which has two USB 2.0 ports.

Chart Edit

Very Small Internal Memory

The average internal memory of many processor core computers that are a comparable age to the Z840 is 22GB. At only 8 gigabytes, the HP Z840 has a fairly small internal memory compared to most of the other many processor core computers that have been available for around the same time as the Z840.

Chart Edit

Quite Slow Max Memory Bandwidth Supported Processor

The max memory bandwidth supported processor of many processor core computers that were launched around the same time as the Z840 range from 32GB/s to 68GB/s, and the average max memory bandwidth supported processor is 60GB/s. With a max memory bandwidth supported processor of only 59 gigabytes per second, the HP Z840 has a fairly slow max memory bandwidth supported processor compared to most of the other comparable spec desktop computers that have been available for around the same time as the Z840.

3 Other reasons to consider the HP Z840

Released Over Two Years Ago

It was over two years ago when this many processor core computer was released.

Average Hard Drive Capacity

At 1,000 gigabyte, the HP Z840 has a pretty average hard drive capacity compared to most of the other many processor core computers that have been around for more than two years.

Chart Edit

HDD Storage Medium

The HP Z840 has an HDD storage medium which is faster than most personal computers of this spec and age. Most many processor core computers that are a similar age to 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.
