64-Bit Processor Operating Mode

This PC supports a 64-bit processor operating mode, which is typical of many computers of this type and age.

Chart Edit

Two CPUs Configuration (max)

The HP Z640 takes more CPUs configuration (max) than most of the many processor core personal computers that were launched around the same time as the Z640. Most of the computers of this age and type only take one CPU configuration (max), however this personal computer takes two CPUs configuration (max).

Chart Edit

Eight USB 3.0 (3.1 Gen 1) Type-A Ports

The HP Z640 is a eight USB 3.0 (3.1 Gen 1) Type-A port PC. Most of the other many processor core personal computers that came out around the same time as the Z640 have between two and eight USB 3.0 (3.1 Gen 1) Type-A ports.

Chart Edit

Fairly Big Max Internal Memory Supported Processor

The HP Z640 has one of the bigger max internal memory supported processors (768 gigabytes) amongst many processor core personal computers of this age. Many processor core personal computers that are a comparable age to the Z640 have max internal memory supported processors of between 64GB and 770GB.

Chart Edit

Fairly Fast Memory Clock Speed Supported by Processor

Across all the similar spec PCs that were launched more than two years ago the memory clock speeds supported by processors range from 800MHz to 1,600MHz, and the average memory clock speed supported by processor is 1,100MHz. The HP Z640 has a quite fast memory clock speed supported by processor (1,600 megahertz) compared to most of the other comparable spec desktop computers that are a similar age to the Z640.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z640 has a DDR4-SDRAM internal memory type which is newer than the DDR3-SDRAM internal memory type found on most many processor core personal computers that are a comparable age to it.

This computer's internal memory type (DDR4-SDRAM) is in fact the best internal memory type across all many processor core personal computers that have been available for a similar time to the Z640.

The worst internal memory type amongst similar types of computer is DDR3-SDRAM.

Two Ethernet LAN (RJ-45) Ports

The HP Z640 is a two Ethernet LAN (RJ-45) port PC.

Chart Edit

Four PS/2 Ports

The HP Z640 is a four PS/2 port computer. Most of the other desktop computers that have been on the market for more than two years only have between one and three PS/2 ports.

Chart Edit

Eight USB 3.0 Ports

The HP Z640 is a eight USB 3.0 port personal computer. Most of the other many processor core personal computers that are a similar age to the Z640 have between two and eight USB 3.0 ports.

Chart Edit

Fairly High System Bus Data Transfer Rate

At 8 Gigatransfers per second, the HP Z640 has a fairly high system bus data transfer rate compared to most of the other desktop computers of a comparable age and type to the Z640. Many processor core personal computers that were released more than two years ago have system bus data transfer rates of between 5GT/s and 9.6GT/s.

Chart Edit

Seven USB 2.0 Ports

Most similar spec computers that were launched around the same time as the Z640 have between two and nine USB 2.0 ports, including the HP Z640 which has seven USB 2.0 ports.

Chart Edit

DVD Super Multi Optical Drive Type

The optical drive type of this computer is DVD Super Multi, which is the most commonly found optical drive type on personal computers of this age and type.

Chart Edit

7 Reasons Against

Very Small Total Storage Capacity

With a total storage capacity of only 256 gigabytes, the HP Z640 has one of the smaller total storage capacity amongst comparable spec desktop computers of this age. Across all the PCs of a similar age and type to the Z640 the total storage capacity range from 180GB to 8.3TB, and the average total storage capacity is 800GB.

If you want a bigger total storage capacity then you might also want to look at the P900[pl_2535695_price] (1TB), or the P900[pl_2535706_price] (1TB) both from Lenovo or the HP Z840[plb_2520399_price] (1TB) which is also cheaper.

Quite Slow Processor Clock Speed

At only 2.4 gigahertz, the HP Z640 has a quite slow processor clock speed compared to most of the other PCs of this age and type. The average processor clock speed of personal computers that came out around the same time as the Z640 is 2.9GHz.

We compared this PC to all the other 2.4GHz processor clock speed personal computers and we think the HP Z840[plb_2520399_price] which is cheaper is also worth considering.

If this HP computer processor clock speed is not fast enough for you then you might want to consider the Lenovo P700[plb_2552838_price] (2.6GHz) which is also cheaper.

Quite Slow Max Memory Bandwidth Supported Processor

The HP Z640 has a quite slow max memory bandwidth supported processor (only 59 gigabytes per second) compared to most of the other personal computers of this spec and age. Across all the many processor core personal computers that have been around for around the same time as the Z640 the max memory bandwidth supported processor range from 32GB/s to 68GB/s, and the average max memory bandwidth supported processor is 60GB/s.

Chart Edit

Only Two 3.5" Bays

The HP Z640 is a two 3.5" bay personal computer. Most of the other desktop computers of a similar age and spec to the Z640 have between two and five 3.5" bays.

Chart Edit

Quite Slow Maximum Turbo Frequency

With a maximum turbo frequency of only 3.2 gigahertz, the HP Z640 has a fairly slow maximum turbo frequency compared to most of the other PCs that are a comparable age to the Z640. Across all the many processor core personal computers that were released around the same time as the Z640 the maximum turbo frequencies range from 2.5GHz to 4GHz, and the average maximum turbo frequency is 3.5GHz.

Chart Edit

Quite Small Maximum Internal Memory

The smallest maximum internal memory of PCs that are a similar age to the Z640 is 32GB and the biggest is 520GB. With a maximum internal memory of only 32 gigabytes, the HP Z640 has a very small maximum internal memory compared to most of the other PCs that were released more than two years ago.

Chart Edit

Only Two PCI Express X16 (Gen 3.x) Slots

Most computers of a similar spec and age to the Z640 have between two and three PCI Express x16 (Gen 3.x) slots, including the HP Z640 which has two PCI Express x16 (Gen 3.x) slots.

3 Other reasons to consider the HP Z640

Released Over Two Years Ago

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

Average Internal Memory

With an internal memory of 16 gigabytes, the HP Z640 has a pretty average internal memory compared to most of the other similar spec personal computers that have been available for around the same time as the Z640.

We think you might also be interested in some of the other 16GB memory PCs currently available including the HP Z840[plb_2520399_price] which is cheaper.

SSD Storage Medium

The storage speed of this personal computer is SSD, which is the most commonly found storage medium on desktop computers of a similar age and type to it. 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.

We compared this desktop computer to all the other SSD personal computers and we think cheaper desktop computers such as the P900[pl_2535697_price], and the P700[pl_2552838_price] both from Lenovo is also worth considering.
