Very Small Maximum On-Board Graphics Adapter Memory
The average maximum on-board graphics adapter memory of medium processor core computers that have been on the market for around the same time as the OptiPlex 3020 is 1.5GB. With a maximum on-board graphics adapter memory of only 1.024 gigabytes, the OptiPlex 3020 has a quite small maximum on-board graphics adapter memory compared to most of the other personal computers that have been around for around the same time as the OptiPlex 3020.
Very Small Maximum Internal Memory
Across all the medium processor core computers that are a similar age to the OptiPlex 3020 the maximum internal memory range from 2GB to 260GB. The OptiPlex 3020 has one of the smaller maximum internal memory (only 16 gigabytes) amongst medium processor core computers of this age.
Only Four Processor Threads
The OptiPlex 3020 is a four processor thread PC. Most of the other personal computers that have been around for more than two years have between four and seven processor threads.
Only One PCI Express X16 Slot
Most computers of this age and type have between one and two PCI Express x16 slots, including the DELL OptiPlex 3020 which has one PCI Express x16 slot.
Quite Slow Maximum Turbo Frequency
The average maximum turbo frequency of computers of a comparable spec and age to the OptiPlex 3020 is 3.6GHz, and the maximum turbo frequencies range from 1.3GHz to 4.4GHz. At only 3 gigahertz, the DELL OptiPlex 3020 has a fairly slow maximum turbo frequency compared to most of the other similar spec computers that were released more than two years ago.
2 Other reasons to consider the DELL OptiPlex 3020
Released Over Two Years Ago
It was over two years ago when this desktop computer was released.
Average Hard Drive Capacity
The DELL OptiPlex 3020 has a relatively standard hard drive capacity (500 gigabytes) compared to most of the other medium processor core computers that have been on the market for more than two years.
If you are looking for a personal computer with a bigger hard drive capacity then you might also want to look at the HP EliteDesk 800 G1 (£295.17) (1TB) which is also higher rated.
