13 Reasons For

HP Has Good Reviews for Its Desktop Computers

Based on 242 expert and user reviews, HP has good ratings for its personal computers. HP also has good ratings specifically for its many processor core personal computers.

64-Bit Processor Operating Mode

This personal computer supports a 64-bit processor operating mode, which is the most commonly supported processor operating mode on many processor core personal computers that have been on the market for a similar time to it.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

With a max internal memory supported processor of 768 gigabytes, the HP Z820 has one of the bigger max internal memory supported processors amongst many processor core personal computers of this age. Across all the many processor core personal computers that have been around for a comparable time to the Z820 the max internal memory supported processors range from 64GB to 770GB.

Chart Edit

Quite Big Internal Memory

The smallest internal memory of desktop computers of this type and age is 4GB and the biggest is 64GB. The HP Z820 has one of the bigger internal memory (32 gigabytes) amongst many processor core personal computers of this age.

Chart Edit

Quite Big Total Storage Capacity

The HP Z820 has one of the bigger total storage capacity (1,000 gigabyte) amongst many processor core personal computers of this age. Many processor core personal computers that have been around for a similar time to the Z820 have total storage capacity of between 180GB and 8.3TB, and the average total storage capacity is 800GB.

If this desktop computer total storage capacity is not big enough for you then you might also want to look at the Lenovo P700 (£1,851.60) (2TB).

24 Processor Threads

The HP Z820 is a 24 processor thread computer.

Chart Edit

Fairly Big Processor Cache

Across all the many processor core personal computers that have been around for a comparable time to the Z820 the processor caches range from 12MB to 30MB. With a processor cache of 30 megabytes, the HP Z820 has a quite big processor cache compared to most of the other PCs of a similar age and spec to the Z820.

Chart Edit

Very Big Maximum Internal Memory

The average maximum internal memory of desktop computers of this type and age is 140GB. When compared to other comparable spec personal computers that were released more than two years ago, the maximum internal memory of the HP Z820 of 512 gigabytes is one of the biggest.

Chart Edit

Two Ethernet LAN (RJ-45) Ports

The HP Z820 is a two Ethernet LAN (RJ-45) port personal computer. Most of the other personal computers that have been available for a similar time to the Z820 only have one Ethernet LAN (RJ-45) port.

Chart Edit

Three 5.25" Bays

The HP Z820 is a three 5.25" bay personal computer. Most of the other PCs of this spec and age only have between one and two 5.25" bays.

Chart Edit

Three PCI Express X16 (Gen 3.x) Slots

The HP Z820 is a three PCI Express x16 (Gen 3.x) slot computer. Most of the other similar spec computers that are a comparable age to the Z820 have between two and three PCI Express x16 (Gen 3.x) slots.

Chart Edit

Supports One Case Placement

The number of placements supported by the HP Z820 is more than most PCs of this spec and age. This HP desktop computer supports a Vertical case placement, which is the most commonly supported case placement supported by computers that have been around for around the same time as the Z820.

Chart Edit

DVD Super Multi Optical Drive Type

The optical drive type of this computer is DVD Super Multi, which is typical of many similar spec desktop computers that are a comparable age to it.

Chart Edit

5 Reasons Against

Very Slow Memory Clock Speed Supported by Processor

The memory clock speeds supported by processors of computers of a similar type and age to the Z820 range from 800MHz to 1,600MHz, and the average memory clock speed supported by processor is 1,100MHz. The HP Z820 has one of the slower memory clock speeds supported by processors (only 800 megahertz) amongst many processor core personal computers of this age.

Chart Edit

Quite Slow Processor Clock Speed

At only 2.4 gigahertz, the HP Z820 has a quite slow processor clock speed compared to most of the other desktop computers that were launched around the same time as the Z820. The slowest processor clock speed of personal computers that were launched around the same time as the Z820 is 1.6GHz, the fastest is 3.7GHz, and the average processor clock speed is 2.9GHz.

If this many processor core personal computer processor clock speed is not fast enough for you then you might want to look at the P900 (£1,845.46) (2.6GHz), or the P700 (£1,672.40) (2.6GHz) both from Lenovo.

Quite Slow Memory Clock Speed

Comparable spec personal computers that have been around for around the same time as the Z820 have memory clock speeds of between 1,300MHz and 2,200MHz. The HP Z820 has a quite slow memory clock speed (only 1,866 megahertz) compared to most of the other similar spec computers that were released more than two years ago.

Chart Edit

Quite Slow Maximum Turbo Frequency

Personal computers of a comparable spec and age to the Z820 have maximum turbo frequencies of between 2.5GHz and 4GHz. At only 3.2 gigahertz, the HP Z820 has a fairly slow maximum turbo frequency compared to most of the other personal computers of this age and spec.

Chart Edit

Heavy

At 21.1 kilograms, the HP Z820 is quite heavy compared to most of the other many processor core personal computers that have been on the market for around the same time as the Z820. The lightest similar spec personal computer that has been on the market for around the same time as the Z820 is 250g heavy and the heaviest is 30kg.

3 Other reasons to consider the HP Z820

Released Over Two Years Ago

This desktop computer has been on the market for over two years.

Average Hard Drive Capacity

The HP Z820 has a fairly standard hard drive capacity (1,000 gigabyte) compared to most of the other personal computers that came out around the same time as the Z820.

If you are looking for a bigger hard drive capacity then you might want to consider the Lenovo P700 (£1,851.60) (2TB).

HDD Storage Medium

The HP Z820 has a faster storage speed than most many processor core personal computers that are a comparable age to it. This personal computer has an HDD storage medium, whereas most PCs that were launched around the same time as it have a Flash storage medium. 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.
