10 Reasons For

Good Brand

HP many processor core personal computers have good reviews on average and across all desktop computers HP is one of the better rated brands.

Fairly Big Max Internal Memory Supported Processor

Many processor core personal computers that are a similar age to the 840 have max internal memory supported processors of between 64GB and 1.6TB, and the average max internal memory supported processor is 960GB. At 1,536 gigabyte, the HP 840 has a fairly big max internal memory supported processor compared to most of the other many processor core personal computers that were released around the same time as the 840.

Chart Edit

64-Bit Processor Operating Mode

This personal computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on comparable spec desktop computers that have been available for around the same time as it.

Chart Edit

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

Most of the other latest many processor core personal computers only have between two and seven USB 3.0 (3.1 Gen 1) Type-A ports, however the HP 840 has eight USB 3.0 (3.1 Gen 1) Type-A ports.

Chart Edit

Quite Fast Max Memory Bandwidth Supported Processor

At 68.3 gigabytes per second, the HP 840 has a quite fast max memory bandwidth supported processor compared to most of the other many processor core personal computers that have been available for a similar time to the 840. The average max memory bandwidth supported processor of latest comparable spec desktop computers is 67GB/s.

Chart Edit

Only Released Eight Months Ago

HP only released the 840 eight months ago. Newer PCs like this one are likely to use more advanced technology.

Fairly Big Total Storage Capacity

The total storage capacity of personal computers that have been around for around the same time as the 840 range from 250GB to 2.2TB, and the average total storage capacity is 770GB. At 1,000 gigabyte, the HP 840 has a quite big total storage capacity compared to most of the other latest comparable spec PCs.

There are a number of alternative 1TB total storage capacity personal computers currently available that you might also want to consider including cheaper desktop computers such as the HP 440[plb_3066153_price].

Fairly Big Maximum Internal Memory

The maximum internal memory of desktop computers that have been on the market for the last year range from 32GB to 520GB. At 512 gigabytes, the HP 840 has a quite big maximum internal memory compared to most of the other recently released many processor core personal computers.

Chart Edit

DDR4-SDRAM Internal Memory Type

This computer has a DDR4-SDRAM internal memory type, which is typical of many latest similar spec personal computers.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP 840 is more than most recently released many processor core personal computers. This PC has an 8x DIMM memory slot, which is the most commonly found memory slot found on many processor core personal computers that are a comparable age to the 840.

Chart Edit

4 Reasons Against

Very Slow Processor Clock Speed

At only 2.1 gigahertz, the HP 840 has a fairly slow processor clock speed compared to most of the other new similar spec computers. The processor clock speeds of many processor core personal computers that have been available for around the same time as the 840 range from 1.6GHz to 3.6GHz, and the average processor clock speed is 2.7GHz.

Chart Edit

Very Slow Maximum Turbo Frequency

At only 3 gigahertz, the HP 840 has a fairly slow maximum turbo frequency compared to most of the other many processor core personal computers that have been on the market for around the same time as the 840. The slowest maximum turbo frequency of many processor core personal computers that are a comparable age to the 840 is 2.8GHz and the fastest is 4GHz.

Chart Edit

Quite Low System Bus Data Transfer Rate

The average system bus data transfer rate of many processor core personal computers that came out around the same time as the 840 is 8.5GT/s, and the system bus data transfer rates range from 6.4GT/s to 9.6GT/s. At only 8 Gigatransfers per second, the HP 840 has a quite low system bus data transfer rate compared to most of the other recently released desktop computers.

Chart Edit

Heavy

The weights of recently released many processor core personal computers range from 250g to 28kg. The HP 840 is one of the heavier recently released comparable spec personal computers (21.1 kilograms) amongst PCs of this age.

Chart Edit

3 Other reasons to consider the HP 840

Average Internal Memory

At 16 gigabytes, the HP 840 has a fairly standard internal memory compared to most of the other desktop computers that are a similar age to the 840.

Chart Edit

Average Hard Drive Capacity

At 1,000 gigabyte, the HP 840 has a pretty average hard drive capacity compared to most of the other many processor core personal computers that were launched in the last year.

We think you might also be interested in some of the other 1TB hard drive capacity computers currently available including cheaper PCs such as the HP 440[plb_3066153_price].

Read more Less Chart Edit

HDD Storage Medium

The HP 840 has an HDD storage medium which is faster than the SSD storage medium found on most new many processor core personal computers. 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 this desktop computer to all the other HDD PCs and we think the HP 440[plb_3066153_price] which is cheaper is also worth considering.
