12 Reasons For

HP Has Good Personal Computer Reviews

On average HP many processor core personal computers have good ratings compared to other manufacturers as do all desktop computers produced by HP.

64-Bit Processor Operating Mode

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

Chart Edit

Very Fast Max Memory Bandwidth Supported Processor

The average max memory bandwidth supported processor of PCs that came out more than two years ago is 60GB/s, and the max memory bandwidth supported processor range from 32GB/s to 68GB/s. When compared to other comparable spec PCs that were released more than two years ago that we have assessed, the max memory bandwidth supported processor of the HP Z840 of 68 gigabytes per second is one of the fastest.

Chart Edit

Quite Fast Memory Clock Speed Supported by Processor

With a memory clock speed supported by processor of 1,600 megahertz, the HP Z840 has a fairly fast memory clock speed supported by processor compared to most of the other many processor core personal computers that have been on the market for a similar time to the Z840. The average memory clock speed supported by processor of comparable spec desktop computers that were launched 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

Quite Big Internal Memory

With an internal memory of 32 gigabytes, the HP Z840 has one of the bigger internal memory amongst personal computers of this age. The average internal memory of desktop computers of a similar age and type to the Z840 is 22GB.

Chart Edit

Quite High System Bus Data Transfer Rate

The system bus data transfer rates of personal computers of this age and type range from 5GT/s to 9.6GT/s, and the average system bus data transfer rate is 8GT/s. At 9.6 Gigatransfers per second, the HP Z840 has a quite high system bus data transfer rate compared to most of the other PCs of a comparable age and spec 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 have been available for around the same time as it. Most computers of a similar spec and age to it have a DDR3-SDRAM internal memory type.

A DDR4-SDRAM internal memory type is in fact the best internal memory type amongst all many processor core personal computers that were released around the same time as the Z840.

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

20 Processor Threads

The HP Z840 is a 20 processor thread desktop computer.

Chart Edit

Fairly Big Processor Cache

With a processor cache of 25 megabytes, the HP Z840 has one of the bigger processor caches amongst many processor core personal computers of this age. The processor caches of comparable spec computers that are a similar age to the Z840 range from 12MB to 30MB.

Chart Edit

Fairly Big Solid-State Drive Capacity

Similar spec personal computers that were launched more than two years ago have solid-state drive capacities of between 120GB and 1TB, and the average solid-state drive capacity is 320GB. At 512 gigabytes, the HP Z840 has a fairly big solid-state drive capacity compared to most of the other personal computers that have been around for a similar time to the Z840.

Chart Edit

Blu-Ray RW Optical Drive Type

The HP Z840 has a Blu-Ray RW optical drive type which is better than the DVD Super Multi optical drive type found on most personal computers of a similar type and age to it.

A Blu-Ray RW optical drive type is actually the best optical drive type amongst all many processor core personal computers that have been on the market for more than two years.

Amongst similar types of desktop computer the worst optical drive type is DVD+RW.

Read more Less Chart Edit

Has One Memory Slot

The HP Z840 has a greater number of memory slots than most personal computers of a similar type and age to it. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this HP computer. The memory slots 8x DIMM are also found on this personal computer.

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, the fastest is 3.7GHz, and the average processor clock speed is 2.9GHz. At only 2.3 gigahertz, the HP Z840 has a quite slow processor clock speed compared to most of the other personal computers of a comparable type and age to the Z840.

If you would prefer a faster processor clock speed then you might also want to look at the Lenovo P700 (2.4GHz).

Read more Less Chart Edit

Quite Slow Maximum Turbo Frequency

The maximum turbo frequencies of many processor core personal computers that were released around the same time as the Z840 range from 2.5GHz to 4GHz. The HP Z840 has a quite slow maximum turbo frequency (only 3 gigahertz) compared to most of the other similar spec computers that have been around for around the same time as the Z840.

Chart Edit

Heavy

The HP Z840 is one of the heavier comparable spec PCs that have been around for around the same time as the Z840 (21.1 kilograms) amongst many processor core personal computers of this age. Many processor core personal computers that were released more than two years ago have weights of between 250g and 30kg.

Chart Edit

3 Other reasons to consider the HP Z840

Released Over Two Years Ago

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

SSD Storage Medium

The storage speed of this PC is SSD, which is the most frequently found storage medium on comparable spec desktop computers that are a similar 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 relatively typical total storage capacity compared to most of the other computers of this age and type.

If this desktop computer total storage capacity is too small for you then you might want to consider the HP Z420 (1TB).
