16 Reasons For

HP Has Good Computer Reviews

We checked 242 expert and owner reviews for HP personal computers and found that on average HP has good reviews compared to other manufacturers. We also found that HP has good reviews specifically within its many processor core personal computers range.

Very Fast Max Memory Bandwidth Supported Processor

With a max memory bandwidth supported processor of 76.8 gigabytes per second, the HP 840 has one of the fastest max memory bandwidth supported processor amongst comparable spec desktop computers of this age. Latest PCs have max memory bandwidth supported processor of between 51GB/s and 77GB/s.

Chart Edit

Very Big Max Internal Memory Supported Processor

The HP 840 has one of the biggest max internal memory supported processors (1,536 gigabyte) amongst many processor core personal computers of this age. Latest computers have max internal memory supported processors of between 64GB and 1.6TB.

Chart Edit

64-Bit Processor Operating Mode

This desktop computer supports a 64-bit processor operating mode, which is typical of many PCs that came out in the last year.

Chart Edit

Two CPUs Configuration (max)

The HP 840 takes more CPUs configuration (max) than most of the latest computers. Most of the newly released many processor core personal computers only take one CPU configuration (max), however this computer takes two CPUs configuration (max).

Chart Edit

Only Released Eight Months Ago

As one of the newer personal computers, this personal computer is likely to use more advanced technology.

Very Fast Memory Clock Speed Supported by Processor

With a memory clock speed supported by processor of 1,600 megahertz, the HP 840 has a very fast memory clock speed supported by processor compared to most of the other many processor core personal computers that were launched in the last year. Comparable spec desktop computers that have been on the market for a similar time to the 840 have memory clock speeds supported by processors of between 1,300MHz and 1,600MHz.

Chart Edit

SSD Storage Medium

The storage speed of this computer is SSD, which is typical of many many processor core personal computers that were released in the last 12 months. 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

28 Processor Threads

The HP 840 is a 28 processor thread computer. Most of the other latest many processor core personal computers only have between 6 and 27 processor threads.

Chart Edit

Fairly High System Bus Data Transfer Rate

The HP 840 has one of the higher system bus data transfer rates (9.6 Gigatransfers per second) amongst many processor core personal computers of this age. Across all the comparable spec desktop computers that have been available for the last year the system bus data transfer rates range from 6.4GT/s to 9.6GT/s, and the average system bus data transfer rate is 8.5GT/s.

Chart Edit

Very Big Processor Cache

When compared to other comparable spec computers that are a similar age to the 840, the processor cache of the HP 840 of 35 megabytes is one of the biggest. Across all the many processor core personal computers that are a similar age to the 840 the processor caches range from 15MB to 35MB.

Chart Edit

Very Big Maximum Internal Memory

With a maximum internal memory of 512 gigabytes, the HP 840's maximum internal memory is one of the biggest amongst personal computers that came out around the same time as the 840. Recently released similar spec desktop computers have maximum internal memory of between 32GB and 520GB.

Chart Edit

DDR4-SDRAM Internal Memory Type

This desktop computer has a DDR4-SDRAM internal memory type, which is the most commonly found internal memory type on desktop computers that have been around for a comparable time to it.

Chart Edit

Quite Big Solid-State Drive Capacity

The average solid-state drive capacity of comparable spec desktop computers that are a similar age to the 840 is 380GB. With a solid-state drive capacity of 512 gigabytes, the HP 840 has a quite big solid-state drive capacity compared to most of the other many processor core personal computers that are a similar age to the 840.

Chart Edit

Four 3.5" Bays

The HP 840 is a four 3.5" bay personal computer. Most of the other recently released many processor core personal computers only have between two and three 3.5" bays.

Chart Edit

Has One Memory Slot

The number of memory slots found on the HP 840 is more than most many processor core personal computers that have been on the market for the last year. This HP desktop computer has an 8x DIMM memory slot, which is the most frequently found memory slot found on new comparable spec computers.

Chart Edit

3 Reasons Against

Only Two USB 2.0 Ports

The HP 840 is a two USB 2.0 port computer.

Chart Edit

Only One Ethernet LAN (RJ-45) Port

The HP 840 is a one Ethernet LAN (RJ-45) port computer. Most of the other many processor core personal computers that have been available for around the same time as the 840 have one Ethernet LAN (RJ-45) port.

Chart Edit

Heavy

The lightest many processor core personal computer that was launched around the same time as the 840 is 250g heavy and the heaviest is 28kg. At 21.1 kilograms, the HP 840 is fairly heavy compared to most of the other many processor core personal computers that were launched around the same time as the 840.

3 Other reasons to consider the HP 840

Average Internal Memory

With an internal memory of 32 gigabytes, the HP 840 has a relatively average internal memory compared to most of the other new comparable spec PCs.

If you would prefer a bigger internal memory then you might want to look at the DELL Precision T7810 (£1,798.80) (64GB).
