Chart Edit

Two CPUs Configuration (max)

The HP Z840 takes more CPUs configuration (max) than most of the many processor core personal computers that have been on the market for around the same time as the Z840. This HP desktop computer is a personal computer that takes two CPUs configuration (max) compared to most of the similar spec desktop computers that are a comparable age to the Z840 which only take one CPU configuration (max).

Chart Edit

Very Fast Max Memory Bandwidth Supported Processor

The max memory bandwidth supported processor of personal computers of this spec and age range from 32GB/s to 68GB/s, and the average max memory bandwidth supported processor is 60GB/s. With a max memory bandwidth supported processor of 68 gigabytes per second, the HP Z840 has one of the fastest max memory bandwidth supported processor amongst personal computers of this age.

Chart Edit

Quite Big Max Internal Memory Supported Processor

The smallest max internal memory supported processor of computers that are a comparable age to the Z840 is 64GB and the biggest is 770GB. With a max internal memory supported processor of 768 gigabytes, the HP Z840 has one of the bigger max internal memory supported processors amongst similar spec PCs of this age.

Chart Edit

Fairly Fast Memory Clock Speed Supported by Processor

Across all the PCs of a comparable age and spec to the Z840 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. With a memory clock speed supported by processor of 1,600 megahertz, the HP Z840 has a fairly fast memory clock speed supported by processor compared to most of the other many processor core personal computers that have been on the market for around the same time as the Z840.

Chart Edit

Fairly Big Total Storage Capacity

The total storage capacity of similar spec personal computers that have been available for a comparable time to the Z840 range from 180GB to 8.3TB, and the average total storage capacity is 800GB. At 1,000 gigabyte, the HP Z840 has a fairly big total storage capacity compared to most of the other desktop computers of a similar spec and age to the Z840.

If this computer total storage capacity is too small for you then you might want to consider the Lenovo P700[plb_2552850_price] (2TB).
