Photoshop refused to work with a custom brush. One smear worked, and the next one got an error: there is not enough memory .
It happened because there were a lot of layers, and in the background, a browser with 20+ tabs and Facebook messenger worked in parallel. I used it all, so I couldn’t close anything.
My PC has 8 GB of RAM. At that moment I decided that this was not enough and it was time to update.
Below I figured out what RAM does on your Mac and why its choice is so important.
What is RAM
In any computer, you can independently choose two types of storage. For Mac, this is:
• HDD / SSD from 128 GB, where you store your files;
• 8–32 GB RAM, which transfers data between the processor and the permanent storage.
The 15 and 16-inch MacBook Pros integrate graphics processing units (GPUs). Added to them is a third view, VRAM. The manufacturer sets its volume himself.
RAM is called RAM because it stores current operations . It depends on its volume how many tasks and how quickly your MacBook can pull them.
It is as if the hard drive was a bookshelf, and the RAM – the holder of all the necessary papers on your desktop.
RAM affects everything
Mac power is made up of four components:
processor performs tasks
• Random access memory (RAM) provides quick access to them
• Permanent storage serves as a bank for information
• The graphics processor and its RAM form and display an image.
The first three affect the speed of execution and the volume of processes, the fourth is responsible for the quality of the “picture” in real time.
Through the RAM passes all the information during system operation.
For example, when rendering a photo or video, data is taken both from the permanent storage and from RAM, but it is always sent through it to the processor, which does all the work.
Or, if there is not enough memory, then open tabs in Safari will significantly slow down the process.
And the memory simply cannot stand the huge Excel spreadsheet, because it may not fit the entire file when working in parallel with other programs.
Therefore, choose the size of RAM depending on the size of the files you are going to work with. Moreover, since 2012, the RAM in the MacBook is soldered to the board and it is impossible to change it after the purchase.
The redundancy of RAM during operation will be almost negligible. But productivity will plummet if it is missed.
4 GB is enough for text only
The operating system will already eat up half the memory, so RAM will be enough only for text editors and simple web browsing. Considering that Apple hasn’t put so much memory on a Mac for a long time, it makes no sense to consider it.
8 GB became a necessary minimum
There are enough of them for front-end programming, because the processor is more important in it. The same goes for making music .
But already at an average load, like processing in Photoshop with 10-15 layers or editing in Full HD, you have to close the rest of the program. Moreover, the render will take longer because the whole process will not fit in the allocated memory.
16 GB will be a balanced solution
Mac will cope with large tables and will not hang from them. Composers and music groups also have enough.
Drawing and photo take a lot of resources if the files are large, and the batch return in Lightroom will definitely occupy most of these 16 GB.
32 GB needed for the most demanding tasks
For example, they will be needed in editing soundtracks with dozens of layered effects, large projects with 8K materials, and anyone who uses browsers, photoshop, drawing programs at the same time and is generally engaged in the continuous production of media.
In a 4K video render, the difference between 16 and 32 GB will not be as dramatic as between 8 and 16.
When working with video and 3D-graphics, both RAM and GPU power will be equally important.
More than 32 GB solve hardcore problems
Yes, there is now a Mac Pro where you can install 1.5 TB of RAM. It is needed by a minority of people for, for example, genomics (gene simulations) or complex models in machine learning. Giant calculations that require serious investment outside the consumer 100-500 thousand rubles.
To whom much RAM is needed. Quick list
If you haven’t figured it out yet, then just choose the main task and choose a Mac based on it:
📝 Text Processing: 4 GB
Browsers: 8-∞ GB
🎼 Writing music and tracks: 8 GB
💻 Front-end programming: 8-16 GB
graphics: 16 GB
📸 Photo processing: 16 GB
🪁 Animation design: 16 GB
🎬 Video editing: 16 GB
🎮 Creating 3D graphics: 16 GB
📊 Working with tables: 16 GB
16-32 GB back-end
programming 🤹♀️ Serious 32 GB multitasking
As a result, the majority is ideally 16 GB, but 8 GB is enough for many
Almost all manufacturers, including Apple, put 8 GB each, because less is no longer possible, and more buyers do not require a total.
But another two or three years, and so much memory will limit almost everyone: the resolution of displays is growing, the quality of the content too. Along with it is the temporary weight of the files that swap RAM.
Anyone who works with the “visual”, now I advise you to switch to 16 GB.
The main thing to remember is that the browser first eats the memory. Therefore, before deciding on a purchase, decide what is more expensive for you: spend on RAM or spend time every day to find and close unnecessary tabs.
