22 Reasons For

HP Personal Computers Have Good Reviews

HP has good average ratings for its medium processor core personal computers as well as across its entire personal computer range.

64-Bit Processor Operating Mode

This desktop computer supports a 64-bit processor operating mode, which is the most commonly supported processor operating mode on medium processor core personal computers that have been around for around the same time as it.

Chart Edit

Quite Fast Max Memory Bandwidth Supported Processor

Computers of a similar age and type to the Z420 have max memory bandwidth supported processor of between 10GB/s and 68GB/s, and the average max memory bandwidth supported processor is 30GB/s. The HP Z420 has a fairly fast max memory bandwidth supported processor (59.7 gigabytes per second) compared to most of the other desktop computers of a similar spec and age to the Z420.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

The average max internal memory supported processor of medium processor core personal computers that are a similar age to the Z420 is 88GB, and the max internal memory supported processors range from 2GB to 770GB. At 256 gigabytes, the HP Z420 has a quite big max internal memory supported processor compared to most of the other medium processor core personal computers that are a comparable age to the Z420.

Chart Edit

Quite Big Discrete Graphics Adapter Memory

The HP Z420 has a quite big discrete graphics adapter memory (3,072 gigabytes) compared to most of the other personal computers of this spec and age. Across all the medium processor core personal computers that were released more than two years ago the discrete graphics adapter memory capacities range from 1GB to 6.2TB, and the average discrete graphics adapter memory is 2TB.

Chart Edit

Very Fast Processor Clock Speed

When compared to other medium processor core personal computers that came out more than two years ago that we have assessed, the HP Z420's processor clock speed of 3.7 gigahertz is one of the fastest. PCs of a similar type and age to the Z420 have processor clock speeds of between 1GHz and 4.1GHz, and the average processor clock speed is 3.1GHz.

Chart Edit

Quite Big Internal Memory

Computers that have been available for around the same time as the Z420 have internal memory of between 2GB and 64GB, and the average internal memory is 7.5GB. The HP Z420 has a fairly big internal memory (16 gigabytes) compared to most of the other personal computers that were released more than two years ago.

Chart Edit

SSD Storage Medium

The HP Z420 has a faster storage speed than most medium processor core personal computers that came out more than two years ago. This computer has an SSD storage medium, whereas most PCs that have been on the market for a similar time to it have an HDD storage medium. Solid State Drives (SSD) store information in transistors on a circuit board rather than on optical or magnetic media. This has the advantage of being much faster than a traditional HDD drive.

An SSD storage medium is in fact the best storage speed across all medium processor core personal computers that were launched around the same time as the Z420.

Across similar types of desktop computer the worst storage speed is HDD.
