Based on 242 expert and owner reviews, HP has good ratings for its personal computers. HP also has good ratings specifically within its few processor core computers range compared to other manufacturers.
Only Released Four Months Ago
This computer is one of the latest desktop computers to be released.
64-Bit Processor Operating Mode
This computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on recently released similar spec desktop computers.
4.4 On-Board Graphics Adapter OpenGL Version
This PC supports a 4.4 on-board graphics adapter OpenGL version, which is typical of many latest few processor core computers.
HDD Storage Medium
The storage speed of this computer is HDD, which is the most commonly found storage medium on comparable spec desktop computers that have been available for 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.
If the storage speed of this computer is not fast enough for you then you might want to look at the Chromebox 3010 (SSD), or the OptiPlex 3040 (£386.98) (SSD) both from DELL or the HP 400 G2 (£610.65) (SSD).
3 PCI Express Slots Version
This desktop computer supports a 3 PCI Express slots version, which is typical of many new comparable spec PCs.
+5 More reasons for
DDR4-SDRAM Internal Memory Type
The 400 G2 Mini has a DDR4-SDRAM internal memory type which is newer than most few processor core computers that were released around the same time as it. Most latest comparable spec computers have a DDR3L-SDRAM internal memory type.
This computer's internal memory type (DDR4-SDRAM) is actually the best internal memory type amongst all few processor core computers that were launched in the last year.
A DDR3-SDRAM internal memory type is the worst internal memory type across comparable types of computer.
Has One Memory Slot
The 400 G2 Mini has a greater number of memory slots than most PCs that have been available for a comparable time to it. The most frequently found memory slot is 2x DIMM, but this memory slot is not found on this personal computer. The memory slots 2x SO-DIMM are also found on this desktop computer.
The average weight of few processor core computers that have been on the market for the last year is 4.8kg. The 400 G2 Mini is fairly light (only 1.3 kilograms) compared to most of the other newly released comparable spec desktop computers.
Across all the comparable spec computers that were launched in the last 12 months the heights range from 33mm to 500mm, and the average height is 230mm. At only 34 millimeters, the 400 G2 Mini is very short compared to most of the other newly released few processor core computers.
3 Reasons Against
Quite Slow On-Board Graphics Adapter Dynamic Frequency
At only 950 megahertz, the HP 400 G2 Mini has a fairly slow on-board graphics adapter dynamic frequency compared to most of the other comparable spec PCs that have been around for a similar time to the 400 G2 Mini. The slowest on-board graphics adapter dynamic frequency of recently released computers is 790MHz and the fastest is 1,200MHz.
Very Slow Memory Clock Speed Supported by Processor
With a memory clock speed supported by processor of only 1,333 megahertz, the 400 G2 Mini has one of the slower memory clock speeds supported by processors amongst personal computers of this age. Across all the new few processor core computers the memory clock speeds supported by processors range from 1,300MHz to 1,900MHz.
Only Two USB 2.0 Ports
Most new desktop computers have between one and five USB 2.0 ports, including the HP 400 G2 Mini which has two USB 2.0 ports.
4 Other reasons to consider the HP 400 G2 Mini
Average Processor Clock Speed
At 3.2 gigahertz, the 400 G2 Mini has a fairly average processor clock speed compared to most of the other comparable spec computers that are a similar age to the 400 G2 Mini.
Desktop computers with a faster processor clock speed that might be worth considering include the 550-230na (£384.98) (3.7GHz), the 550-231na (£382.97) (3.7GHz), or the 550-232na (£382.97) (3.7GHz) all from HP.
Average Total Storage Capacity
At 500 gigabytes, the 400 G2 Mini has a fairly standard total storage capacity compared to most of the other few processor core computers that have been around for a similar time to the 400 G2 Mini.
Computers with a bigger total storage capacity that might also be worth looking at include the 550-230na (£384.98) (1TB), the 550-231na (£382.97) (1TB), or the 550-232na (£382.97) (1TB) all from HP.
Average Hard Drive Capacity
At 500 gigabytes, the 400 G2 Mini has a relatively average hard drive capacity compared to most of the other latest few processor core computers.
If this desktop computer hard drive capacity is not big enough for you then you might want to consider the 550-230na (£384.98) (1TB), the 550-231na (£382.97) (1TB), or the 550-232na (£382.97) (1TB) all from HP.
+2 Other reasons
Average Internal Memory
At 4 gigabytes, the 400 G2 Mini has a relatively typical internal memory compared to most of the other few processor core computers that have been around for around the same time as the 400 G2 Mini.
If this HP personal computer internal memory is too small for you then you might also want to look at the 550-230na (£384.98) (8GB), the 550-231na (£382.97) (8GB), or the 550-232na (£382.97) (8GB) all from HP.
