Very Fast Max Memory Bandwidth Supported Processor

When compared to other PCs of this type and age, the HP Z420's max memory bandwidth supported processor of 68 gigabytes per second is one of the fastest. The max memory bandwidth supported processor of medium processor core personal computers that have been available for around the same time as the Z420 range from 10GB/s to 68GB/s.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

With a max internal memory supported processor of 768 gigabytes, the HP Z420 has a fairly big max internal memory supported processor compared to most of the other medium processor core personal computers that have been around for around the same time as the Z420. Desktop computers that have been around for a similar time to the Z420 have max internal memory supported processors of between 2GB and 770GB.

Chart Edit

Fairly Big Internal Memory

When compared to other computers that have been around for around the same time as the Z420 that we have checked, the internal memory of the HP Z420 of 16 gigabytes is one of the biggest. The average internal memory of similar spec PCs that have been on the market for around the same time as the Z420 is 7.5GB, and the internal memory range from 2GB to 64GB.

Fairly Big Hard Drive Capacity

With a hard drive capacity of 1,000 gigabyte, the HP Z420 has a fairly big hard drive capacity compared to most of the other computers of this type and age. The smallest hard drive capacity of medium processor core personal computers that have been on the market for around the same time as the Z420 is 320GB, the biggest is 3TB, and the average hard drive capacity is 800GB.

Chart Edit

Quite Big Total Storage Capacity

With a total storage capacity of 1,000 gigabyte, the HP Z420 has one of the bigger total storage capacity amongst medium processor core personal computers of this age. The smallest total storage capacity of desktop computers that have been on the market for a comparable time to the Z420 is 32GB, the biggest is 3TB, and the average total storage capacity is 710GB.

Chart Edit

3 PCI Express Slots Version

This computer supports a 3 PCI Express slots version, which is the most commonly supported PCI Express slots version on computers of this spec and age.
