8 Reasons For
HP Has Good Reviews for Its PCs
We checked the reviews from users and experts of hundreds of PCs to determine an average rating for each personal computer manufacturer. On average HP personal computers have good ratings from experts and owners.
64-Bit Processor Operating Mode
This computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on comparable spec personal computers that have been available for a similar time to it.
Two Ethernet LAN (RJ-45) Ports
The HP 840 is a two Ethernet LAN (RJ-45) port PC. Most of the other recently released many processor core PCs only have one Ethernet LAN (RJ-45) port.
Eight USB 3.0 Ports
The HP 840 has more USB 3.0 ports than most of the latest many processor core PCs. Most of the many processor core PCs that have been on the market for a comparable time to the 840 only have between four and seven USB 3.0 ports, however this computer has eight USB 3.0 ports.
DDR4-SDRAM Internal Memory Type
This personal computer has a DDR4-SDRAM internal memory type, which is typical of many latest many processor core PCs.
Quite Big Maximum Internal Memory
At 512 gigabytes, the HP 840 has a quite big maximum internal memory compared to most of the other personal computers that were released in the last 12 months. The average maximum internal memory of latest many processor core PCs is 160GB.
+3 More reasons for
Has One Memory Slot
The HP 840 has a greater number of memory slots than most desktop computers that are a similar age to it. The most commonly found memory slot is 4x DIMM, but this memory slot is not found on this HP personal computer. The memory slots 8x DIMM are also found on this desktop computer.
DVD Super Multi Optical Drive Type
The optical drive type of this PC is DVD Super Multi, which is typical of many many processor core PCs that were released in the last 12 months.
4 Reasons Against
Only 10 Mbit/s Ethernet LAN Data Rate
This computer supports 10, 100, 1000, 10, 100 and 1000 Mbit/s Ethernet LAN data transfer rates, which is the most commonly supported Ethernet LAN data rate on desktop computers that have been around for a comparable time to it.
Quite Slow Max Memory Bandwidth Supported Processor
The max memory bandwidth supported processor of personal computers that have been available for around the same time as the 840 range from 42GB/s to 77GB/s. With a max memory bandwidth supported processor of only 59 gigabytes per second, the HP 840 has one of the slower max memory bandwidth supported processor amongst many processor core PCs of this age.
With a weight of 21.1 kilograms, the HP 840 is quite heavy compared to most of the other desktop computers that are a comparable age to the 840. Across all the desktop computers that have been available for a similar time to the 840 the weights range from 250g to 30kg, and the average weight is 12kg.
With a depth of 525 millimeters, the HP 840 is quite deep compared to most of the other latest comparable spec desktop computers. Similar spec personal computers that are a comparable age to the 840 have depths of between 160mm and 620mm, and the average depth is 390mm.

6 Other reasons to consider the HP 840
Released Ten Months Ago
It was ten months ago when HP released the 840.
Average Internal Memory
With an internal memory of 16 gigabytes, the HP 840 has a relatively standard internal memory compared to most of the other many processor core PCs that came out in the last year.
Desktop computers with a bigger internal memory that might be worth considering include the 640 MT (£3,932.45) (32GB), or the 840 (£4,103.79) (32GB) both from HP.
Average Hard Drive Capacity
The HP 840 has a relatively typical hard drive capacity (1,000 gigabyte) compared to most of the other PCs that are a similar age to the 840.
If this many processor core desktop computer hard drive capacity is not big enough for you then you might want to look at the DELL Precision T7810 (£1,798.80) (2TB).
+4 Other reasons
Average Total Storage Capacity
The HP 840 has a fairly average total storage capacity (1,000 gigabyte) compared to most of the other recently released desktop computers.
If this personal computer total storage capacity is not big enough for you then you might also want to consider the DELL Precision T7810 (£1,798.80) (2TB).
HDD Storage Medium
The HP 840 has a faster storage speed than most similar spec desktop computers that were launched in the last 12 months. This HP personal computer has an HDD storage medium, whereas most newly released many processor core PCs have an SSD storage medium. 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.
Computers with a faster storage speed that might be worth looking at include the 840 (£4,103.79) (SSD), or the 640 MT (£3,115.21) (SSD) both from HP.
Average Processor Clock Speed
The HP 840 has a fairly average processor clock speed (2.4 gigahertz) compared to most of the other latest comparable spec computers.
If you are looking for a faster processor clock speed then you might also want to look at the 840 (£3,619.96) (2.5GHz), or the Z440 (£1,872.06) (3GHz) both from HP.
