The average max internal memory supported processor of comparable spec computers that are a similar age to the Z840 is 620GB, and the max internal memory supported processors range from 64GB to 770GB.

Chart Edit

Very Fast Memory Clock Speed Supported by Processor

When compared to other personal computers of this spec and age, the HP Z840's memory clock speed supported by processor of 1,600 megahertz is one of the fastest. The average memory clock speed supported by processor of computers that have been available for around the same time as the Z840 is 1,100MHz, and the memory clock speeds supported by processors range from 800MHz to 1,600MHz.

Chart Edit

Fairly Big Total Storage Capacity

Quite Fast Memory Clock Speed

Many processor core computers that have been on the market for more than two years have memory clock speeds of between 1,300MHz and 2,200MHz. With a memory clock speed of 2,133 megahertz, the HP Z840 has a fairly fast memory clock speed compared to most of the other desktop computers that were released more than two years ago.

Chart Edit

Very Big Maximum Internal Memory

The maximum internal memory of the HP Z840 of 512 gigabytes is one of the biggest amongst personal computers of a comparable type and age to the Z840. The smallest maximum internal memory of many processor core computers that are a comparable age to the Z840 is 32GB, the biggest is 520GB, and the average maximum internal memory is 140GB.

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 desktop computers of this type and age.

This desktop computer's internal memory type (DDR4-SDRAM) is in fact the best internal memory type across all comparable spec personal computers that have been available for more than two years.

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

Eight USB 3.0 Ports

Most PCs of a similar age and type to the Z840 have between two and eight USB 3.0 ports, including the HP Z840 which has eight USB 3.0 ports.

Chart Edit

Fairly High System Bus Data Transfer Rate

The average system bus data transfer rate of many processor core computers that came out more than two years ago is 7.9GT/s, and the system bus data transfer rates range from 5GT/s to 9.6GT/s. With a system bus data transfer rate of 8 Gigatransfers per second, the HP Z840 has one of the higher system bus data transfer rates amongst many processor core computers of this age.

The HP Z840 has a greater number of memory slots than most PCs that came out more than two years ago. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this PC. 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 desktop computer is DVD Super Multi, which is typical of many comparable spec computers that have been around for more than two years.

Chart Edit

3 Reasons Against

Quite Slow Processor Clock Speed

The slowest processor clock speed of computers of this age and type is 1.6GHz and the fastest is 3.7GHz. With a processor clock speed of only 2.4 gigahertz, the HP Z840 has a quite slow processor clock speed compared to most of the other many processor core computers that have been around for around the same time as the Z840.

Desktop computers with a faster processor clock speed that might also be worth looking at include the Lenovo Thinkstation P500 (3.5GHz), or the HP Z440 ($1,400.73) (3.5GHz).

4 Other reasons to consider the HP Z840

Released Over Two Years Ago

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

Average Internal Memory

With an internal memory of 16 gigabytes, the HP Z840 has a fairly standard internal memory compared to most of the other personal computers of a comparable spec and age to the Z840.

Chart Edit

Average Hard Drive Capacity

At 1,000 gigabyte, the HP Z840 has a pretty typical hard drive capacity compared to most of the other PCs that have been on the market for a similar time to the Z840.

Desktop computers with a bigger hard drive capacity that might be worth considering include the Lenovo P700 (2TB) which is also cheaper.

Read more Less Chart Edit

HDD Storage Medium

The HP Z840 has an HDD storage medium which is faster than the Flash storage medium found on most desktop computers of a comparable age and type to it. 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.

We compared all the other HDD desktop computers to this desktop computer and we think cheaper desktop computers such as the Lenovo P900 is also worth considering.

If the storage speed of this many processor core computer is too slow for you then you might also want to consider the Thinkstation P500 (SSD), or the P900 ($3,232.33) (SSD) both from Lenovo or the HP Z640 (SSD).
