14 Reasons For

64-Bit Processor Operating Modes

This PC supports a 64-bit processor operating modes, which is typical of many personal computers of a similar age and type to it.

Chart Edit

Very Fast Memory Bandwidth Supported by Processor (max)

With a memory bandwidth supported by processor (max) of 59.7 gigabytes per second, the HP Z420 has a very fast memory bandwidth supported by processor (max) compared to most of the other medium processor cores computers that were launched around the same time as the Z420. Across all the comparable spec desktop computers that have been available for a similar time to the Z420 the memory bandwidth supported by processor (max)s range from 10GB/s to 68GB/s, and the average memory bandwidth supported by processor (max) is 30GB/s.

Chart Edit

HP Has Good PC Reviews

Based on 322 expert and user reviews, HP has good ratings for its PCs. HP also has good ratings specifically within its medium processor cores computers range.

Quite Big Maximum Internal Memory Supported by Processor

The maximum internal memory supported by processors of medium processor cores computers that were launched more than a year ago range from 2GB to 770GB. With a maximum internal memory supported by processor of 256 gigabytes, the HP Z420's maximum internal memory supported by processor is one of the biggest amongst personal computers of a comparable age and spec to the Z420.

Chart Edit

Very Fast Processor Frequency

The average processor frequency of personal computers of a comparable spec and age to the Z420 is 3.1GHz. At 3.7 gigahertz, the HP Z420 has a very fast processor frequency compared to most of the other medium processor cores computers that were released one year ago.

If this personal computer processor frequency is not fast enough for you then you might also want to consider the MSI Nightblade Z97[plb_2788717_price] (4GHz) which is also higher rated.

SSD Storage Media

The HP Z420 has a faster storage speed than most similar spec PCs that are a comparable age to it. This desktop computer has an SSD storage media, whereas most medium processor cores computers that are a similar age to it have an HDD storage media. 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 media is actually the best storage speed amongst all medium processor cores computers that were released more than a year ago.

An HDD storage media is the worst storage speed across similar types of PC.

3 PCI Express Slots Version

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

Chart Edit

10/100/1000Base-T(X) Cabling Technology

This computer has a 10/100/1000Base-T(X) cabling technology, which is typical of many medium processor cores computers that are a comparable age to it.

Chart Edit

Three Number of 5.25" Bayss

Most PCs of a comparable age and spec to the Z420 have between one and three number of 5.25" bayss, including the HP Z420 which has three number of 5.25" bayss.

Chart Edit

Quite Big Maximum Internal Memory

The HP Z420 has one of the bigger maximum internal memorys (64 gigabytes) amongst similar spec desktop computers of this age. The smallest maximum internal memory of computers that have been on the market for a similar time to the Z420 is 2GB, the biggest is 260GB, and the average maximum internal memory is 32GB.

Chart Edit

Very Big Processor Cache

The smallest processor cache of medium processor cores computers that were released around the same time as the Z420 is 2MB, the biggest is 10MB, and the average processor cache is 6.5MB. The processor cache of the HP Z420 of 10 megabytes is one of the biggest amongst personal computers of a comparable age and spec to the Z420.

Chart Edit

Three Number of 3.5" Bayss

Most computers of this age and type have between one and six number of 3.5" bayss, including the HP Z420 which has three number of 3.5" bayss.

Chart Edit

Two PCI Express X16 (Gen 3.x) Slotss

The HP Z420 is a two PCI Express x16 (Gen 3.x) slots computer.

Chart Edit

Has One Memory Slots

The number of memory slots found on the HP Z420 is more than most personal computers of this age and spec. The most frequently found memory slots is 4x DIMM, but this memory slots is not found on this HP personal computer. The memory slotss 8x DIMM are also found on this desktop computer.

Chart Edit

3 Reasons Against

Quite Slow Memory Clock Speeds Supported by Processor

The memory clock speeds supported by processors of medium processor cores computers that came out more than a year ago range from 800MHz to 2,200MHz, and the average memory clock speeds supported by processor is 1,500MHz. The HP Z420 has one of the slowest memory clock speeds supported by processors (only 800 megahertz) amongst medium processor cores computers of this age.

Chart Edit

Very Small Total Storage Capacity

Similar spec desktop computers that have been available for more than a year have total storage capacitys of between 4GB and 3.6TB. At only 256 gigabytes, the HP Z420 has a quite small total storage capacity compared to most of the other medium processor cores computers that have been on the market for around the same time as the Z420.

It may also be worth also looking at one of the other 256GB total storage capacity PCs currently available including the Lenovo M93p Tower[plb_2433249_price] which has better reviews.
