9 Reasons For

Two CPU Configuration (max)s

The HP Z840 takes more CPU configuration (max)s than most of the many processor cores PCs that have been on the market for around the same time as the Z840. Most of the similar spec personal computers that were released more than two years ago only take one CPU configuration (max), however this computer takes two CPU configuration (max)s.

HP Has Good Reviews for Its PCs

HP is one of the better rated desktop computer brands according to average reviews from experts and users, and HP also has good ratings for its many processor cores PCs.

Fairly Fast Memory Bandwidth Supported by Processor (max)

With a memory bandwidth supported by processor (max) of 68 gigabytes per second, the HP Z840 has a fairly fast memory bandwidth supported by processor (max) compared to most of the other PCs that have been around for a similar time to the Z840. Across all the PCs that have been on the market for around the same time as the Z840 the memory bandwidth supported by processor (max)s range from 32GB/s to 68GB/s.

Chart Edit

Very Fast Memory Clock Speeds Supported by Processor

PCs of a comparable age and spec to the Z840 have memory clock speeds supported by processors of between 800MHz and 1,600MHz. The HP Z840 has one of the fastest memory clock speeds supported by processors (1,600 megahertz) amongst PCs of this age.

Chart Edit

Quite Big Internal Memory

At 32 gigabytes, the HP Z840 has a quite big internal memory compared to most of the other many processor cores PCs that have been around for around the same time as the Z840. The smallest internal memory of personal computers that were released more than two years ago is 4GB, the biggest is 64GB, and the average internal memory is 24GB.

Chart Edit

Quite High System Bus Rate

The average system bus rate of PCs of this age and type is 8GT/s, and the system bus rates range from 5GT/s to 9.6GT/s. At 9.6 Gigatransfers per second, the HP Z840 has a quite high system bus rate compared to most of the other similar spec computers that were released more than two years ago.

Chart Edit

Quite Fast Memory Clock Speed

The memory clock speeds of desktop computers of this spec and age range from 1,300MHz to 2,200MHz, and the average memory clock speed is 1,900MHz. The HP Z840 has one of the faster memory clock speeds (2,133 megahertz) amongst personal computers of this age.

Chart Edit

Quite Big Solid-State Drive Capacity

The solid-state drive capacitys of PCs that are a comparable age to the Z840 range from 120GB to 1TB. With a solid-state drive capacity of 512 gigabytes, the HP Z840 has one of the bigger solid-state drive capacitys amongst many processor cores PCs of this age.

Chart Edit

Has One Memory Slots

The HP Z840 has a greater number of memory slots than most computers that have been available for around the same time as it. The most commonly found memory slots is 4x DIMM, but this memory slots is not found on this personal computer. The memory slotss 8x DIMM are also found on this desktop computer.

Chart Edit

4 Reasons Against

Quite Slow Processor Frequency

The processor frequencys of many processor cores PCs that came out around the same time as the Z840 range from 1.6GHz to 3.7GHz, and the average processor frequency is 2.9GHz. At only 2.3 gigahertz, the HP Z840 has a fairly slow processor frequency compared to most of the other many processor cores PCs that were released more than two years ago.

If this personal computer processor frequency is not fast enough for you then you might also want to look at the Lenovo P700[plb_2552850_price] (2.4GHz).

Very Slow Processor Boost Frequency

With a processor boost frequency of only 3 gigahertz, the HP Z840 has one of the slower processor boost frequencys amongst PCs of this age. The average processor boost frequency of similar spec desktop computers that are a comparable age to the Z840 is 3.5GHz, and the processor boost frequencys range from 2.5GHz to 4GHz.

Chart Edit

Only One Ethernet LAN (RJ-45) Ports

The HP Z840 is a one ethernet LAN (RJ-45) ports PC. Most of the other many processor cores PCs that have been around for a comparable time to the Z840 have between one and two ethernet LAN (RJ-45) portss.

Chart Edit

Heavy

The average weight of desktop computers of this spec and age is 11kg. At 21.1 kilograms, the HP Z840 is fairly heavy compared to most of the other desktop computers that are a comparable age to the Z840.

3 Other reasons to consider the HP Z840

Released Over Two Years Ago

This computer has been on the market for over two years.

SSD Storage Media

The storage speed of this personal computer is SSD, which is the most commonly found storage media on personal computers of this type and age. 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 relatively average total storage capacity compared to most of the other many processor cores PCs that have been available for a similar time to the Z840.
