7 Reasons For

HP Desktop Computers Have Good Reviews

Many processor core personal computers manufactured by HP have good ratings on average compared to other brands. We also checked the reviews for all PCs (not just many processor core personal computers) and found that HP also has good ratings across its entire range.

64-Bit Processor Operating Mode

This desktop computer supports a 64-bit processor operating mode, which is the most frequently supported processor operating mode on many processor core personal computers that are a comparable age to it.

Chart Edit

Two CPUs Configuration (max)

The HP 640 takes more CPUs configuration (max) than most of the many processor core personal computers that have been around for a similar time to the 640. This desktop computer is a computer that takes two CPUs configuration (max) compared to most of the recently released PCs which only take one CPU configuration (max).

Chart Edit

Quite Fast Memory Clock Speed Supported by Processor

Across all the latest many processor core personal computers the memory clock speeds supported by processors range from 1,300MHz to 1,600MHz. With a memory clock speed supported by processor of 1,600 megahertz, the HP 640 has one of the faster memory clock speeds supported by processors amongst comparable spec PCs of this age.

Chart Edit

Fairly Big Total Storage Capacity

The average total storage capacity of many processor core personal computers that have been available for around the same time as the 640 is 770GB, and the total storage capacity range from 250GB to 2.2TB. At 1,000 gigabyte, the HP 640 has a quite big total storage capacity compared to most of the other newly released computers.

If this many processor core personal computer total storage capacity is not big enough for you then you might want to look at the DELL Precision T7810 (£1,798.80) (2TB).

Fairly Big Maximum Internal Memory

The smallest maximum internal memory of many processor core personal computers that were released around the same time as the 640 is 32GB and the biggest is 520GB. With a maximum internal memory of 256 gigabytes, the HP 640 has a quite big maximum internal memory compared to most of the other comparable spec computers that were launched around the same time as the 640.

Chart Edit

DDR4-SDRAM Internal Memory Type

This computer has a DDR4-SDRAM internal memory type, which is typical of many latest many processor core personal computers.

Chart Edit

4 Reasons Against

Quite Slow Max Memory Bandwidth Supported Processor

The average max memory bandwidth supported processor of many processor core personal computers that are a comparable age to the 640 is 67GB/s, and the max memory bandwidth supported processor range from 51GB/s to 77GB/s. The HP 640 has a fairly slow max memory bandwidth supported processor (only 59 gigabytes per second) compared to most of the other many processor core personal computers that have been on the market for around the same time as the 640.

Chart Edit

Only 12 Processor Threads

The HP 640 is a 12 processor thread personal computer. Most of the other similar spec personal computers that were released around the same time as the 640 have between 6 and 27 processor threads.

Chart Edit

Very Small Processor Cache

The HP 640 has a quite small processor cache (only 15 megabytes) compared to most of the other similar spec desktop computers that have been on the market for a comparable time to the 640. The smallest processor cache of latest similar spec personal computers is 15MB and the biggest is 35MB.

Chart Edit

Quite Low System Bus Data Transfer Rate

With a system bus data transfer rate of only 8 Gigatransfers per second, the HP 640 has a quite low system bus data transfer rate compared to most of the other PCs that are a comparable age to the 640. Across all the PCs that were released around the same time as the 640 the system bus data transfer rates range from 6.4GT/s to 9.6GT/s, and the average system bus data transfer rate is 8.5GT/s.

5 Other reasons to consider the HP 640

Released Eleven Months Ago

It was eleven months ago when this personal computer was released.

Average Internal Memory

The HP 640 has a relatively average internal memory (16 gigabytes) compared to most of the other many processor core personal computers that have been on the market for around the same time as the 640.

If this many processor core personal computer internal memory is not big enough for you then you might want to consider the HP 840 (£3,847.56) (32GB).

Average Hard Drive Capacity

With a hard drive capacity of 1,000 gigabyte, the HP 640 has a fairly typical hard drive capacity compared to most of the other many processor core personal computers that have been around for around the same time as the 640.

If you are looking for a bigger hard drive capacity then you might also want to look at the DELL Precision T7810 (£1,798.80) (2TB).

Read more Less Chart Edit

HDD Storage Medium

The HP 640 has an HDD storage medium which is faster than the SSD storage medium found on most many processor core personal computers that came out in the last 12 months. 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.

If the storage speed of this many processor core personal computer is too slow for you then you might want to consider the HP Z440 (£2,514.00) (SSD).

Average Processor Clock Speed

The HP 640 has a relatively typical processor clock speed (2.4 gigahertz) compared to most of the other recently released PCs.

If you would prefer a faster processor clock speed then you might also want to consider the HP 840 (£3,847.56) (2.5GHz).
