Fairly Fast Memory Clock Speed

The average memory clock speed of PCs of this age and type is 1,900MHz, and the memory clock speeds range from 1,300MHz to 2,200MHz. The HP Z840 has one of the faster memory clock speeds (2,133 megahertz) amongst many processor cores desktop computers of this age.

Chart Edit

Very Big Maximum Internal Memory

When compared to other comparable spec personal computers that were launched more than two years ago that we have assessed, the maximum internal memory of the HP Z840 of 512 gigabytes is one of the biggest. Across all the comparable spec computers that were released more than two years ago the maximum internal memorys range from 32GB to 520GB, and the average maximum internal memory is 120GB.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z840 has a DDR4-SDRAM internal memory type which is newer than the DDR3-SDRAM internal memory type found on most many processor cores desktop computers that came out around the same time as it.

This desktop computer's internal memory type (DDR4-SDRAM) is in fact the best internal memory type amongst all many processor cores desktop computers that have been around for more than two years.

Amongst similar types of desktop computer the worst internal memory type is DDR3-SDRAM.

Only HDD Storage Media

The HP Z840 has an HDD storage media which is faster than most many processor cores desktop computers that have been around for around the same time as it. Most many processor cores desktop computers that have been on the market for a comparable time to it have a Flash storage media. 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.

An HDD storage media is in fact the worst storage speed amongst all many processor cores desktop computers that have been around for more than two years.

Amongst comparable types of personal computer the best storage speed is SSD.
