With a maximum internal memory supported by processor of 768 gigabytes, the HP Z840 has one of the bigger maximum internal memory supported by processors amongst computers of this age.

Chart Edit

HP PCs Have Good Reviews

We checked 322 user and expert reviews for HP computers and found that on average HP has good ratings compared to other brands. We also found that HP has good ratings specifically within its many processor cores desktop computers range.

Chart

Fairly Fast Memory Clock Speeds Supported by Processor

The average memory clock speeds supported by processor of comparable spec desktop computers that are a similar age to the Z840 is 1,100MHz. The HP Z840 has one of the faster memory clock speeds supported by processors (1,600 megahertz) amongst many processor cores desktop computers of this age.

Chart Edit

Quite Big Total Storage Capacity

At 1,000 gigabyte, the HP Z840 has a fairly big total storage capacity compared to most of the other personal computers of a similar age and type to the Z840. The smallest total storage capacity of personal computers that were released more than two years ago is 180GB and the biggest is 8.3TB.

If you are looking for a desktop computer with a bigger total storage capacity then you might also want to consider the Lenovo P700 (£1,851.60) (2TB).

Quite High System Bus Rate

The system bus rates of personal computers of this type and age range from 5GT/s to 9.6GT/s. The HP Z840 has a fairly high system bus rate (9.6 Gigatransfers per second) compared to most of the other personal computers that are a similar age to the Z840.

Chart Edit

Fairly Fast Memory Clock Speed

The slowest memory clock speed of PCs of this spec and age is 1,300MHz, the fastest is 2,200MHz, and the average memory clock speed is 1,900MHz. With a memory clock speed of 2,133 megahertz, the HP Z840 has one of the faster memory clock speeds amongst personal computers of this age.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z840 has a DDR4-SDRAM internal memory type which is newer than most PCs that were released around the same time as it. Most many processor cores desktop computers that have been on the market for around the same time as it have a DDR3-SDRAM internal memory type.

A DDR4-SDRAM internal memory type is actually the best internal memory type amongst all desktop computers of a similar spec and age to the Z840.

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

5 Reasons Against

Quite Slow Processor Frequency

The average processor frequency of many processor cores desktop computers that have been around for more than two years is 2.9GHz, and the processor frequencys range from 1.6GHz to 3.7GHz. At only 2.3 gigahertz, the HP Z840 has a quite slow processor frequency compared to most of the other desktop computers of this age and type.

Chart Edit

Only HDD Storage Media

The HP Z840 has an HDD storage media which is faster than most PCs of a comparable age and spec to it. Most similar spec PCs that were released more than two years ago have a Flash storage media. 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.

An HDD storage media is actually the worst storage speed across all many processor cores desktop computers that are a comparable age to the Z840.

Across similar types of personal computer the best storage speed is SSD.
