10 Reasons For

Good Brand

We checked 242 user and expert reviews for HP PCs and found that on average HP has good ratings. We also found that HP has good ratings specifically within its many processor core personal computers 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 personal computers of this spec and age.

Chart Edit

Two CPUs Configuration (max)

The HP Z640 is a desktop computer that takes two CPUs configuration (max).

Chart Edit

Fairly Fast Max Memory Bandwidth Supported Processor

The HP Z640 has a quite fast max memory bandwidth supported processor (68 gigabytes per second) compared to most of the other desktop computers of a comparable type and age to the Z640. The slowest max memory bandwidth supported processor of desktop computers of this age and type is 32GB/s and the fastest is 68GB/s.

Chart Edit

Quite Fast Memory Clock Speed Supported by Processor

Across all the PCs that have been on the market for a similar time to the Z640 the memory clock speeds supported by processors range from 800MHz to 1,600MHz. At 1,600 megahertz, the HP Z640 has a fairly fast memory clock speed supported by processor compared to most of the other PCs of a comparable age and type to the Z640.

Chart Edit

Fairly High System Bus Data Transfer Rate

The HP Z640 has one of the higher system bus data transfer rates (9.6 Gigatransfers per second) amongst many processor core personal computers of this age. Many processor core personal computers that were released around the same time as the Z640 have system bus data transfer rates of between 5GT/s and 9.6GT/s, and the average system bus data transfer rate is 8GT/s.

Chart Edit

DDR4-SDRAM Internal Memory Type

The HP Z640 has a newer internal memory type than most many processor core personal computers that have been available for a similar time to it. This computer has a DDR4-SDRAM internal memory type, whereas most many processor core personal computers that were released more than two years ago have a DDR3-SDRAM internal memory type.

This personal computer's internal memory type (DDR4-SDRAM) is actually the best internal memory type across all many processor core personal computers that were launched around the same time as the Z640.

Across comparable types of personal computer the worst internal memory type is DDR3-SDRAM.

20 Processor Threads

The HP Z640 is a 20 processor thread computer. Most of the other computers of this spec and age have between 6 and 23 processor threads.

Chart Edit

Fairly Big Processor Cache

The HP Z640 has one of the bigger processor caches (25 megabytes) amongst many processor core personal computers of this age. Across all the computers that have been available for more than two years the processor caches range from 12MB to 30MB, and the average processor cache is 20MB.

Chart Edit

Blu-Ray RW Optical Drive Type

The HP Z640 has a Blu-Ray RW optical drive type which is better than most computers of this age and spec. Most PCs that have been around for around the same time as it have a DVD Super Multi optical drive type.

A Blu-Ray RW optical drive type is actually the best optical drive type amongst all similar spec desktop computers that are a comparable age to the Z640.

A DVD+RW optical drive type is the worst optical drive type amongst comparable types of personal computer.

3 Reasons Against

Very Small Total Storage Capacity

The HP Z640 has a fairly small total storage capacity (only 256 gigabytes) compared to most of the other PCs of a similar age and spec to the Z640. The average total storage capacity of comparable spec computers that were released more than two years ago is 800GB.

If you want a bigger total storage capacity then you might want to look at the DELL Precision T5610 (£1,318.80) (500GB).

Read more Less Chart Edit

Quite Slow Processor Clock Speed

With a processor clock speed of only 2.3 gigahertz, the HP Z640 has one of the slower processor clock speeds amongst many processor core personal computers of this age. The slowest processor clock speed of many processor core personal computers that are a comparable age to the Z640 is 1.6GHz, the fastest is 3.7GHz, and the average processor clock speed is 2.9GHz.

If this personal computer processor clock speed is too slow for you then you might want to look at the Lenovo P700 (£1,851.60) (2.4GHz).

Quite Slow Maximum Turbo Frequency

The HP Z640 has one of the slower maximum turbo frequencies (only 3 gigahertz) amongst many processor core personal computers of this age. PCs of a comparable age and type to the Z640 have maximum turbo frequencies of between 2.5GHz and 4GHz, and the average maximum turbo frequency is 3.5GHz.

Chart Edit

2 Other reasons to consider the HP Z640

Average Internal Memory

The HP Z640 has a pretty standard internal memory (16 gigabytes) compared to most of the other PCs of a comparable age and type to the Z640.

Chart Edit

SSD Storage Medium

The storage speed of this PC is SSD, which is typical of many many processor core personal computers that were released around the same time as 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.
