Understanding Software System Requirements: A Plain English Guide

You’ve found the software you want to buy, but then you hit the system requirements section and it’s full of jargon: processor speeds in GHz, RAM in GB, graphics cards with model numbers you’ve never heard of, and storage requirements that seem oddly specific. What does any of it actually mean — and how do you know if your computer can run the software?

This plain English guide breaks down the most common system requirement terms so you can make confident purchasing decisions.

How to Check Your Current Specs

Before comparing your machine to any requirements list, you need to know what you’re working with. On Windows 11, the quickest way is to right-click the Start button and select System. This shows your processor, installed RAM, and Windows version. For graphics card information, open Device Manager and expand the Display Adapters section.

Alternatively, press Windows + R, type dxdiag, and press Enter. The DirectX Diagnostic Tool gives you a comprehensive overview of your system in one place.

Processor (CPU)

The processor is your computer’s brain. Requirements lists will often specify a minimum processor model or speed, such as “1 GHz dual-core processor” or “Intel Core i5 8th generation or later.”

What the numbers mean: GHz (gigahertz) measures the clock speed — roughly how many operations per second the processor can perform. More GHz generally means faster processing for single-threaded tasks. Cores refer to the number of independent processing units within the chip — more cores mean better performance when running multiple tasks simultaneously.

In practice: Most software distinguishes between a minimum requirement (what you need to run the software at all) and a recommended requirement (what you need to run it comfortably). Always aim to meet the recommended spec if possible. Running on the absolute minimum will result in sluggish performance.

For reference, Windows 11 Pro requires a 1 GHz processor with at least 2 cores on a compatible 64-bit processor — a bar that any machine purchased in the last seven or eight years should comfortably clear.

RAM (Memory)

RAM (Random Access Memory) is your computer’s short-term working memory. When you open applications, the data they need is loaded into RAM for fast access. The more RAM you have, the more applications you can run simultaneously without slowdown.

What you need:

• 4 GB — Minimum for Windows 11 and basic Office use. Adequate for light tasks on a single application at a time.
• 8 GB — The recommended minimum for comfortable Office use, web browsing, and email simultaneously. This is the sweet spot for most business users.
• 16 GB — Recommended for professional applications. If you’re running AutoCAD, Revit, or other Autodesk products, 16 GB is the practical minimum.
• 32 GB or more — For complex 3D modelling, large BIM projects, animation work in Maya, or running multiple resource-intensive applications simultaneously.

Storage (Hard Drive or SSD)

Storage requirements tell you how much space the software will occupy on your drive. Modern software is increasingly large — full Office installations can run to several gigabytes, while Autodesk products with all components installed can consume 20–40 GB or more.

HDD vs SSD: Many system requirement lists now specify an SSD (Solid State Drive) as recommended rather than a traditional HDD (Hard Disk Drive). SSDs load applications and files dramatically faster than HDDs. If your machine has an HDD and you’re finding things slow, upgrading to an SSD is often the single most impactful hardware change you can make.

Available space vs total space: Requirements list the space needed for installation. Make sure you have that much free space — not just total storage. A drive that’s 90% full will also cause performance problems regardless of software requirements.

Graphics Card (GPU)

For most Office applications and general business software, the integrated graphics built into your processor is perfectly adequate. However, for 3D modelling, rendering, and animation software, a dedicated GPU makes a significant difference.

What to look for: VRAM (Video RAM) is the graphics card’s own memory. For Autodesk products like Revit, Inventor, and Maya, 4 GB of VRAM is a workable minimum, with 8 GB recommended for complex projects. OpenGL and DirectX version support are also commonly listed — modern GPUs from NVIDIA, AMD, and Intel all support current versions.

If you’re considering the Autodesk AEC Collection or PDMC Collection, investing in a workstation with a certified NVIDIA Quadro or AMD Radeon Pro card will deliver noticeably better performance and stability than a consumer gaming GPU.

Operating System Version

Software will often list supported operating systems explicitly — “Windows 10 (64-bit) or Windows 11” is a common example. Note the 64-bit requirement: most software sold today requires a 64-bit OS. Windows 11 is 64-bit only, so this is covered automatically if you’re on a modern machine.

Office 2024 Professional Plus requires Windows 10 or Windows 11. It does not support Windows 8.1 or Windows 7. If you’re on an older OS and want to run current Office, upgrading to Windows 11 Pro first is the right approach.

Internet Connection Requirements

Some software requires an internet connection for activation or ongoing use, while others work entirely offline after installation. Office 2024 and Office 2021 purchased as perpetual licences from GetRenewedTech activate once and then work offline. Autodesk products accessed via annual subscription require periodic online check-ins to validate the subscription.

A Quick Reference Summary

Understanding these terms takes away the uncertainty from software purchases. Before buying any software from GetRenewedTech, check your current specs using the dxdiag tool and compare them to the product’s listed requirements. Most modern machines will handle Office products without issue — and for Autodesk professional tools, a workstation-class machine will give you the best experience.
