We checked 265 user and expert reviews for HP desktop computers and found that on average HP has good reviews compared to other brands. We also found that HP has good reviews specifically for its medium processor core computers.
64-Bit Processor Operating Mode
This personal computer supports a 64-bit processor operating mode, which is the most commonly supported processor operating mode on recently released similar spec personal computers.
Supports One Case Placement
The HP 400 G2 has a greater number of placements than most personal computers that were launched around the same time as it. The most frequently supported case placement is Vertical, but this case placement is not supported by this desktop computer. The case placements Horizontal are also supported by this personal computer.
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 medium processor core computers that came out around the same time as it.
3 PCI Express Slots Version
This personal computer supports a 3 PCI Express slots version, which is typical of many medium processor core computers that were released in the last year.
The HP 400 G2 is fairly shallow (only 177 millimeters) compared to most of the other comparable spec personal computers that are a similar age to the 400 G2. Medium processor core computers that have been on the market for around the same time as the 400 G2 have depths of between 34mm and 600mm.
+3 More reasons for
Across all the medium processor core computers that came out in the last 12 months the weights range from 38g to 23kg. With a weight of only 1.3 kilograms, the HP 400 G2 is quite light compared to most of the other similar spec PCs that were released around the same time as the 400 G2.
When compared to other medium processor core computers that have been around for around the same time as the 400 G2 that we have assessed, the HP 400 G2's height of only 34 millimeters is one of the shortest. The shortest computer that came out around the same time as the 400 G2 is 10mm high, the tallest is 530mm, and the average height is 300mm.
8 Reasons Against
Quite Slow Processor Clock Speed
At only 2.5 gigahertz, the HP 400 G2 has a fairly slow processor clock speed compared to most of the other new comparable spec personal computers. New medium processor core computers have processor clock speeds of between 1.3GHz and 4GHz.
It may also be worth considering one of the other 2.5GHz processor clock speed desktop computers currently available including the Lenovo ThinkCentre M900 Tiny which is cheaper.
If you would prefer a faster processor clock speed then you might want to look at the 400 G3 MT (3.2GHz and cheaper), or the 400 G3 SFF (3.2GHz and cheaper) both from HP.
Very Small Internal Memory
With an internal memory of only 4 gigabytes, the HP 400 G2 has a fairly small internal memory compared to most of the other PCs that were launched in the last year. The internal memory of comparable spec computers that have been available for around the same time as the 400 G2 range from 2GB to 32GB, and the average internal memory is 8.1GB.
We compared this desktop computer to all the other 4GB memory PCs and we think the M700 ($639.95), and the M700 both from Lenovo or the HP Z230 SFF which is cheaper is also worth considering.
If you would prefer a desktop computer with a bigger internal memory then you might want to consider the 600 G2 (8GB and cheaper), the 600 G2 ($425.00) (8GB and cheaper), or the 400 G3 ($642.99) (8GB and cheaper) all from HP.
Only 10 Mbit/s Ethernet LAN Data Rate
This desktop computer supports a 10|100|1000 Mbit/s Ethernet LAN data rate, which is the most frequently supported Ethernet LAN data rate on latest comparable spec desktop computers.
Quite Small Hybrid Hard Drive (H-HDD) Capacity
The HP 400 G2 has a quite small hybrid hard drive (H-HDD) capacity (only 500 gigabytes) compared to most of the other medium processor core computers that are a comparable age to the 400 G2. Medium processor core computers that are a comparable age to the 400 G2 have hybrid hard drive (H-HDD) capacities of between 8GB and 2TB, and the average hybrid hard drive (H-HDD) capacity is 810GB.
+5 More reasons against
Very Small Maximum On-Board Graphics Adapter Memory
At only 1.7 gigabytes, the HP 400 G2 has a quite small maximum on-board graphics adapter memory compared to most of the other comparable spec desktop computers that have been around for a similar time to the 400 G2. Across all the newly released PCs the maximum on-board graphics adapter memories range from 1GB to 64GB, and the average maximum on-board graphics adapter memory is 7.8GB.
Quite Small Processor Cache
The HP 400 G2 has one of the smaller processor caches (only 6 megabytes) amongst computers of this age. The average processor cache of recently released medium processor core computers is 6.8MB, and the processor caches range from 2MB to 10MB.
Only Four Processor Threads
Most PCs that were launched in the last year have between four and seven processor threads, including the HP 400 G2 which has four processor threads.
Quite Slow Maximum Turbo Frequency
Across all the similar spec desktop computers that have been on the market for the last year the maximum turbo frequencies range from 1.8GHz to 4.2GHz. The HP 400 G2 has one of the slower maximum turbo frequencies (only 3.1 gigahertz) amongst similar spec PCs of this age.
2 Other reasons to consider the HP 400 G2
Average Total Storage Capacity
With a total storage capacity of 500 gigabytes, the HP 400 G2 has a fairly typical total storage capacity compared to most of the other new comparable spec desktop computers.
It may also be worth also looking at one of the other 500GB total storage capacity computers currently available including cheaper personal computers such as the DELL OptiPlex 3040 ($598.15).
PCs with a bigger total storage capacity that might be worth looking at include the HP 400 G3 ($642.99) (1TB) which is also cheaper.
HDD Storage Medium
The storage speed of this personal computer is Hybrid-HDD, which is typical of many medium processor core computers that were launched in the last year. 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.
