Boost PC performance: How more available memory can improve productivity

Boost PC performance: How more available
memory can improve productivity
With more memory available, system performance of three Dell
devices increased, which can translate to a better user experience
Any computer system uses a mix of random access memory, or RAM, and secondary long-term storage such
as solid-state drives (SSDs) to store user and system data. RAM provides temporary storage for the operating
system and applications and other data the user is accessing at any given point. Having multiple applications
open at once taxes RAM. Complex programs, such as those designers rely on, place an obvious burden on RAM,
but browsers are also memory-hungry, especially when users keep many tabs open.
The more RAM in a PC, the greater its capacity to store temporary data, resulting in a smoother user experience.
The fast pace of modern business, where employees experience frequent interruptions and regularly switch
from one task to another, makes having adequate RAM more important than ever. Without it, users waste
valuable time waiting for their systems to retrieve information from slower storage, and productivity and
momentum can suffer.
At PT, we performed hands-on testing to quantify the impact of different amounts of RAM on PC performance,
which can in turn affect user productivity. Using the Procyon®
Office Productivity benchmark, which includes real-
world Microsoft 365 tasks,1
we examined the performance of three Dell™
PCs in two scenarios: first, with all of
each PC’s memory available to run the benchmark, and second, with each PC’s available RAM split between this
benchmark and a second one. With more memory available, all three PCs achieved better performance and took
less time to complete the benchmark. This indicates that equipping PCs with greater RAM capacity could enable
a smoother user experience, sustained focus, and greater productivity. It also suggests that upgrading the RAM
in existing PCs could be a sustainable alternative to purchasing new PCs.

A Principled Technologies report: Hands-on testing. Real-world results.

How we tested
We tested the following devices:
• Dell Latitude 5440 with two 16GB DDR4 SODIMM modules
• Dell Precision 3470 with two 32GB DDR5 SODIMM modules
• Dell OptiPlex Tower Plus 7010 with four 16GB DDR5 UDIMM modules
In our baseline scenario, we ran the Procyon Office Productivity benchmark with no simultaneous workload,
allowing the PCs to take full advantage of their memory while under load. This might reflect a typical workday
of editing documents, opening slide decks, and accessing spreadsheets without multitasking or intensive
applications running in the background.
In the multitasking scenario, we looked at how a system might perform with limited memory available—perhaps
while users jump between different apps, edit 3D graphics, compile code, or navigate multiple browser tabs—
while performing those same productivity tasks. In our tests, PassMark BurnInTest served as a stand-in for these
memory-hungry activities. We configured BurnInTest to utilize 50 percent of each system’s memory, leaving
the other 50 percent available for system processes and the Procyon Office Productivity benchmark. For more
details, see the science behind the report.
Get better everyday performance with more available memory
Procyon Office Productivity rewards faster system responsiveness. When a system achieves a higher overall
score, you could expect to load documents, export Excel sheets, edit PowerPoint decks, and search your inbox
faster.2
When the systems were able to utilize more RAM to run the benchmark—32 GB for the Latitude 5440 and
64 GB for the Precision 3470 and OptiPlex Tower Plus 7010—they consistently delivered higher Procyon Office
Productivity scores.
With insufficient available system memory, you might experience lengthy wait times or even program crashes.
Although you might be able to close some programs to help other processes run faster, this isn’t always a
desirable option for essential apps. Our test results indicate that with more memory available on your system,
you could expect better performance on these everyday productivity tasks. So, instead of letting memory
limitations interrupt your focus, you could improve performance by selecting a system with more RAM or making
the more sustainable choice of adding more RAM to existing systems.
About Dell Branded memory
The Dell Latitude 5440, Dell Precision 3470, and Dell OptiPlex Tower Plus 7010 systems used Dell Branded
memory. Dell Branded memory “has gone through rigorous quality assurance and quality control testing
to ensure it will work with your specific Dell System so it is fully compatible and supported by Dell. Getting
unqualified or generic products from other vendors can cause downtime that can seriously cost your business
and put your entire system at risk.”3

The Dell Latitude 5440
We saw the biggest boost in performance on the Dell Latitude 5440. We tested a system with 32 GB of RAM,
limiting available memory to 16 GB in the multitasking scenario. As Figure 1 shows, when the system could take
full advantage of its memory, it offered significantly better performance on office tasks. When you spend less
time waiting for your system to complete office tasks, you may be able to maintain focus longer and get more
done during the workday.

Figure 2 shows how the Dell Latitude 5440 with all its memory available was able to complete this benchmark
in 27.4 percent less time than it needed while other activities used half of the memory. This time savings could
improve productivity by allowing a user to complete their tasks faster under multitasking conditions.

The Dell Precision 3470
Testing the Dell Precision 3470 yielded similar results. As Figure 3 shows, leaving all 64 GB of memory available
while running the Procyon Office Productivity benchmark enabled the system to achieve a 28.3 percent higher
score on average than it did when we simulated multitasking with programs that took up 32 GB of memory.
With the ability to complete these tasks faster, you could enjoy a smoother user experience while you multitask
throughout the day.

The Dell OptiPlex Tower Plus 7010
As Figure 5 shows, the Dell OptiPlex Tower Plus 7010 achieved a higher overall score with its full memory
available than it did with half the memory available in the multitasking scenario. In other words, if your work
generally uses up 32 GB of memory on this PC, you could see diminished performance as you tackle emails,
spreadsheets, and slide decks on top of the work that takes up half the memory. But if you had 64 GB of memory
available, you could enjoy faster performance on these everyday tasks.

Figure 6 shows the amount of time it took for the Dell OptiPlex Tower Plus 7010 to execute the benchmark with
different amounts of memory available. With all its memory available, it needed 6.9 percent less time.

Conclusion
When your system has plenty of RAM to meet your needs, you can efficiently access the applications and
data you need to finish projects and to-do lists without sacrificing time and focus. Our test results show that
with more memory available, three Dell PCs delivered better performance and took less time to complete the
Procyon Office Productivity benchmark. These advantages translate to users being able to complete workflows
more quickly and multitask more easily. Whether you need the mobility of the Latitude 5440, the creative
capabilities of the Precision 3470, or the high performance of the OptiPlex Tower Plus 7010, configuring
your system with more RAM can help keep processes running smoothly, enabling you to do more without
compromising performance.
