The average discrete graphics adapter memory of desktop computers of a similar spec and age to the Z420 is 4.3GB, and the discrete graphics adapter memory range from 510MB to 8.2GB.

Chart Edit

Quite Slow Memory Clock Speed

The average memory clock speed of many processor core personal computers that are a comparable age to the Z420 is 1,900MHz, and the memory clock speeds range from 1,300MHz to 2,200MHz. The HP Z420 has one of the slower memory clock speeds (only 1,866 megahertz) amongst many processor core personal computers of this age.

Chart Edit

Only Four USB 3.0 Ports

The HP Z420 is a four USB 3.0 port desktop computer. Most of the other PCs of a similar type and age to the Z420 have between two and eight USB 3.0 ports.

Chart Edit

Very Small L3 Cache

The HP Z420 has a fairly small L3 cache (only 12 megabytes) compared to most of the other PCs of a comparable age and type to the Z420. Across all the many processor core personal computers that are a comparable age to the Z420 the L3 caches range from 12MB to 30MB, and the average L3 cache is 20MB.

Chart Edit

Very Small Processor Cache

The HP Z420 has one of the smaller processor caches (only 12 megabytes) amongst many processor core personal computers of this age. The processor caches of similar spec desktop computers that have been around for more than two years range from 12MB to 30MB.

Chart Edit

Very Small Maximum Internal Memory

The average maximum internal memory of computers that were released around the same time as the Z420 is 140GB. The HP Z420 has one of the smaller maximum internal memory (only 64 gigabytes) amongst personal computers of this age.

Chart Edit
