What Computer Do You Need for Photoshop? A Photographer’s Guide to CPU, GPU, RAM and Storage
Buying a computer for photography can be surprisingly complicated.
There are processors, graphics cards, RAM, SSDs, different generations of hardware and an almost endless choice of specifications. Then there is the question that matters most: how much computer do you actually need for photography?
It is tempting to assume that the most expensive workstation must also be the best choice. For photographers, that isn’t necessarily true.
Adobe Photoshop can run perfectly well on a relatively modest modern computer, but the demands increase considerably when you start working with large layered files, panoramas, hundreds of images, high-resolution displays or several applications at the same time.
So, rather than concentrating on individual models that will soon be out of date, let’s look at the components that actually matter.
Start with what you do
Before choosing specifications, think about the sort of photography work you actually do.
Someone editing JPEGs from a camera and making relatively small adjustments has very different requirements from a photographer working with:
- Large RAW files
- Multi-layer Photoshop documents
- High-resolution panoramas
- Focus-stacked images
- Large composites
- Hundreds of images in Lightroom
- 4K or higher-resolution displays
- Video alongside still photography
A computer that is unnecessarily powerful is an expensive way of solving a problem you don’t have.
On the other hand, buying a computer that is only just powerful enough can become frustrating if your files and workflow grow over the next few years.
The trick is to find the sensible middle ground.
The CPU: still one of the most important components
The CPU, or processor, performs much of the general-purpose processing required by Photoshop and other photographic software.
When comparing computers, you will see specifications such as the number of cores, clock speeds and processor generations. More cores do not automatically mean better Photoshop performance, however.
Photoshop can make good use of multiple processor cores for some tasks, but many operations don’t scale perfectly with additional cores. Current independent Photoshop testing continues to show that choosing the right CPU can be more important than simply buying the processor with the largest number of cores.
This is one reason why a sensibly specified desktop can outperform a much more expensive workstation in everyday photographic work.
Don’t buy a processor purely because the number is bigger
Processor names and specifications change constantly, so it is better to compare current benchmarks than rely on a particular model number.
A modern mid-to-high-range CPU is likely to be a much better investment for a photographer than an older flagship processor that was impressive several years ago.
If your computer will also be used for video editing, 3D work or other heavily multi-threaded applications, additional CPU performance may become more valuable.
How much RAM does Photoshop need?
RAM, or system memory, is particularly important when working with large images.
Adobe currently lists 8GB as the minimum for Photoshop and recommends 16GB or more.
For a photographer, however, the sensible amount can be higher depending on the workload.
A rough guide is:
| Photography workload | Sensible RAM |
|---|---|
| Basic photo editing | 16GB |
| Regular Photoshop and Lightroom work | 32GB |
| Large layered files and panoramas | 64GB |
| Very large professional files / multiple demanding applications | 64GB+ |
These aren’t hard rules. A 32GB computer won’t suddenly stop working because you open a particularly large file.
The issue is what happens when the computer runs out of physical memory and starts relying more heavily on storage. Everything can become noticeably slower.
If you regularly work with enormous panoramas or large Photoshop documents, spending some of your budget on additional RAM can make more sense than spending the same money on an unnecessarily powerful graphics card.
The graphics card: important, but don’t overspend
This is one area where computer buying advice for photographers has changed considerably.
Photoshop uses the graphics processor, or GPU, for a number of features and functions. Adobe recommends a compatible DirectX 12 GPU and notes that GPU functionality can be limited when using older or unsupported hardware.
However, that doesn’t mean you need the most expensive graphics card available.
Current Photoshop testing suggests that once you have a capable modern GPU, moving to a much more expensive model may produce surprisingly little additional performance for ordinary Photoshop work. Puget Systems’ current testing, for example, finds that a mid-range GeForce RTX 5070 can perform very close to a high-end RTX 5090 in Photoshop’s GPU-accelerated tasks.
That makes the GPU an area where photographers can potentially save a considerable amount of money.
When does a better GPU make sense?
A more powerful graphics card becomes more attractive if you:
- Work with several high-resolution displays
- Use GPU-intensive Photoshop features regularly
- Edit video
- Use 3D applications
- Work with other GPU-accelerated software
- Need additional graphics memory for particularly demanding projects
For Photoshop alone, though, don’t assume that the most expensive graphics card will automatically make the biggest difference.
Don’t forget graphics memory
Graphics cards have their own memory, known as VRAM.
Adobe currently recommends 4GB of GPU memory for systems driving 4K displays or larger.
For most photographers buying a modern dedicated graphics card, this shouldn’t be a major concern.
If you are buying a new computer today, choosing a current GPU with a sensible amount of VRAM gives you more headroom for future software updates and higher-resolution displays.
SSD storage makes a big difference
If you are still using a traditional hard disk as your main working drive, moving to an SSD can make a dramatic difference to how responsive the computer feels.
Modern computers commonly use NVMe SSDs, which are considerably faster than older SATA SSDs and traditional mechanical hard drives.
For a photographic workstation, a sensible arrangement is often:
Drive 1 – Operating system and applications
Your Windows installation, Photoshop, Lightroom and other software.
Drive 2 – Photographs and working files
Your current projects and other files that you work with regularly.
Drive 3 – Optional scratch/work drive
This can be useful for particularly demanding workflows, although it isn’t essential for everyone.
Adobe itself recommends a fast internal SSD and provides for additional high-speed storage for scratch-disk use.
The important point is that you don’t necessarily need the fastest SSD available.
A modern NVMe drive is already extremely quick for most photographic work. Spending considerably more money for a drive that benchmarks twice as fast doesn’t necessarily make Photoshop twice as fast.
What is a Photoshop scratch disk?
Photoshop uses a scratch disk when it needs additional temporary working space.
If you work with large files and Photoshop frequently reports that the scratch disk is full, adding more storage or ensuring that your existing drive has plenty of free space can help.
A separate fast drive can also be useful for demanding workflows.
But don’t confuse a scratch disk with a backup.
A scratch disk is working space.
It is not a backup of your photographs.
What about Lightroom?
If your workflow involves both Lightroom Classic and Photoshop, the computer needs to cope with both applications.
That makes RAM particularly useful because you may have Lightroom, Photoshop, your browser and other applications open simultaneously.
Storage is also important. Your Lightroom catalogue, previews and working photographs all benefit from a responsive storage setup.
The same principle applies here: don’t simply buy the most expensive components available. Build a balanced system around your actual workflow.
PC or Mac?
For photographers, both Windows PCs and Macs can make excellent editing machines.
The choice often comes down to personal preference, existing equipment, software requirements and budget.
A Windows desktop has the advantage of offering an enormous range of components and the ability to upgrade individual parts later.
A Mac can offer a very integrated hardware and software experience, with Apple Silicon providing excellent performance for photographic applications.
If you already have a computer, monitor, storage and other peripherals that you are happy with, replacing the entire setup may not always be necessary.
Desktop or laptop?
A desktop will generally give you more performance for your money and makes upgrading easier.
It is also easier to build a system with:
- More RAM
- Multiple internal drives
- A larger graphics card
- Better cooling
- Multiple monitors
A laptop wins on portability.
If you regularly work on location, travel for assignments or need to edit photographs away from your studio, portability may be worth paying for.
Just remember that you are often paying more for a laptop to provide similar performance to a desktop.
Don’t forget the monitor
A powerful computer connected to a poor monitor isn’t a particularly useful photography workstation.
For photographers, the display is one of the most important parts of the system because it is where you actually judge your photographs.
Consider:
- Resolution
- Colour accuracy
- Panel quality
- Viewing angle
- Brightness
- Screen size
- Hardware calibration
- Colour gamut
A photographer spending thousands on a computer but very little on the monitor may have the priorities the wrong way around.
How much should you spend?
There is no universal figure.
The right budget depends on the type of photography you do.
A photographer editing straightforward RAW files doesn’t need the same machine as someone producing enormous commercial composites or editing 8K video.
It is also worth considering how long you expect the computer to last.
A computer that costs more initially may make sense if it gives you several years of comfortable use. But paying for specifications that have little effect on your workflow is simply wasting money.
Think about where your current computer slows down.
Is it:
- Opening applications?
- Applying complex filters?
- Running out of RAM?
- Working with enormous Photoshop documents?
- Importing and browsing photographs?
- Exporting large batches?
- Running several applications together?
- Running out of storage?
The answer should influence where you spend your upgrade budget.
A balanced computer is better than an extreme one
One of the easiest mistakes when buying a photography PC is to create an unbalanced specification.
For example, you could spend a huge amount on a graphics card while using relatively little RAM.
Or buy a very powerful processor but install a small, slow storage drive.
Or build a workstation with enormous amounts of RAM that your workflow never comes close to using.
A better approach is to build a balanced system.
For a serious photographer, that might mean a modern mid-to-high-range processor, 32GB of RAM, a capable dedicated GPU, fast NVMe storage and enough capacity for current projects.
Photographers working with exceptionally large files may want 64GB or more.
The exact component models will change. The principles don’t.
Don’t forget your backups
There is one part of your computer system that is considerably more important than whether your processor is a little faster than somebody else’s.
Your backup system.
A £4,000 computer won’t help if the drive containing ten years of photographs fails.
Your photographs should exist in more than one location, with at least one backup kept separately from the computer.
Consider using a combination of:
- Local backup drives
- Automated backup software
- External drives
- Network storage
- Cloud or off-site backup
The computer is replaceable.
Your photographs may not be.
How long should a photography computer last?
Technology moves quickly, but that doesn’t mean you need to replace your computer every year.
If your existing system runs Photoshop comfortably and isn’t holding you back, there may be little reason to replace it simply because a newer processor or graphics card has appeared.
On the other hand, if you’re constantly waiting for Photoshop, running out of RAM or watching large files grind your system to a halt, an upgrade can make a genuine difference to your working day.
The best time to replace a computer is usually when it is limiting your photography — not simply because a newer model exists.
The best computer is the one that suits your photography
Computer specifications will continue to change.
Today’s flagship processor will eventually become yesterday’s technology, and today’s expensive graphics card will eventually be replaced by something faster and cheaper.
That is why it is better to understand what each component does rather than trying to follow a list of recommended models.
For most photographers, the priorities are straightforward:
A capable modern CPU.
Enough RAM for the size of your files.
A supported, sensible GPU rather than necessarily the most expensive one.
Fast SSD storage.
A good-quality monitor.
And, above all, a reliable backup system.
You don’t need to spend thousands of pounds to use Photoshop effectively.
You need a computer that is balanced, reliable and suited to the way you actually work.
And when the next generation of processors and graphics cards arrives, that advice will still be useful.
