The M5 is faster and more efficient, but the M4 handles most everyday tasks just fine

The M5 chip runs about 15 to 20 percent faster than the M4 in real work — opening files, editing photos, switching between apps. It also uses less power to do the same job, which means longer battery life on laptops. The M4 is still a capable chip that handles email, web browsing, video calls, and document editing without lag. The choice between them comes down to what you actually do with your computer and whether the speed gain is worth the cost difference.

Both chips are made by Apple and use the same basic design — they have a processor core (the part that does calculations), a graphics core (the part that draws images), and memory built in. The M5 has more of everything: more processor cores in some models, faster memory, and a more efficient design that wastes less energy as heat.

Key Takeaways

  • The M5 is 15 to 20 percent faster than the M4 in most real tasks, with the biggest gains in video editing, photo processing, and running multiple programs at once.
  • The M4 is still fast enough for everyday work like email, web browsing, writing, and video calls, and will not feel slow for these tasks.
  • M5 laptops have longer battery life because the chip uses less power to do the same work, often gaining 1 to 3 extra hours per charge.
  • The M4 costs less upfront and will remain useful for five or more years, so the speed difference may not justify the price for casual users.
  • The specific model matters as much as the chip generation — an M5 with fewer cores may perform similarly to an M4 with more cores in some tasks.

Where the M5 pulls ahead: speed and power use

The M5 has more processor cores in most configurations, meaning it can do more calculations at the same time. When you open a large photo file in Photoshop while running a web browser with ten tabs and a video call, the M5 distributes that work across more cores and finishes faster. The M4 can do all those things too, but it takes longer because it has fewer cores working in parallel.

The M5 also has a faster memory connection, which means data moves between the processor and memory quicker. This matters most when you work with large files — video editing, 3D rendering, or processing thousands of photos at once. For everyday tasks like typing a document or checking email, the difference is invisible.

Battery life improves with the M5 because Apple redesigned how the chip uses power. The M5 accomplishes the same work with less electrical current, so your laptop runs longer before needing to charge. On a MacBook Air, this often means 2 to 3 extra hours of real use per day.

When the M4 is the right choice

If you spend most of your time in a web browser, writing documents, or watching videos, the M4 will feel just as fast as the M5. These tasks do not push the processor hard — they are waiting for you to type or click more than they are waiting for the chip to finish work. The M4 handles them when ready on both chips.

The M4 costs less, which matters if you are buying a computer on a budget or replacing one that still works. A MacBook Air with an M4 chip is hundreds of dollars cheaper than the same model with an M5. If you keep your computer for five years, that savings is real money, and the M4 will still be fast enough for most work in 2029.

The M4 is also still new enough that software is optimized for it. You will not run into programs that are too demanding or too old to work. The M4 will not become obsolete quickly — it will remain a capable machine for at least five to seven years of normal use.

Speed differences in real tasks

In web browsing, the difference is barely noticeable. Both chips load pages when ready and handle dozens of tabs without stuttering. The M5 might load a very large page 1 or 2 seconds faster, but you will not feel the difference in daily use.

In photo editing with Lightroom or Photoshop, the M5 processes filters and exports faster. If you edit 100 photos in a session, the M5 might save you 10 to 15 minutes total. The M4 does the same work — it just takes longer.

In video editing, the gap widens. Exporting a 10-minute video takes noticeably longer on the M4, especially if the video is 4K resolution. The M5 handles this work more smoothly and finishes sooner. If video editing is a regular part of your work, the M5 saves real time.

In gaming, both chips run modern games well. The M5 maintains higher frame rates in demanding games, but the M4 is still playable. If you play casual games or older titles, you will not notice the difference.

How to decide between them

Ask yourself what you do most often. If your answer is email, web browsing, documents, and video calls, the M4 is the right choice. You will not feel the speed difference, and you will save money. If your answer includes video editing, photo processing, 3D work, or running many heavy programs at once, the M5 pays for itself in time saved.

Consider how long you plan to keep the computer. If you replace it every three years, the M4 is fine — it will be fast enough for that entire period. If you keep computers for five years or longer, the M5 is a better long-term investment because it starts faster and stays faster as software becomes more demanding.

Think about battery life if you use a laptop away from a desk. The M5's extra hours per charge matter if you travel, work in coffee shops, or move between rooms often. If your laptop stays plugged in most of the time, battery life is less important.

Check the price difference at the time you are buying. Sometimes the M5 costs only 10 or 15 percent more, which makes it a better value. Other times the difference is 25 or 30 percent, which tips the balance toward the M4 unless you do heavy work.

The core difference: efficiency, not just speed

The M5 is not just faster — it is more efficient. Apple redesigned the chip to do more work per unit of power, which is why it runs cooler and lasts longer on battery. This efficiency compounds over time. A computer that uses less power stays cooler, which means the fan runs less often, which means less noise and longer component life.

The M4 is also efficient compared to older Intel chips, so do not think of it as a power hog. It is just that the M5 takes efficiency further. For someone who works in a quiet office or library, the quieter operation of the M5 might matter. For someone who works at home with ambient noise, it probably does not.

Frequently Asked Questions

Will the M4 become obsolete soon?

No. The M4 will remain capable for five to seven years of normal use. Software will continue to support it, and it will not become slow for everyday tasks. You will not feel pressure to upgrade just because a newer chip exists.

Is the M5 worth the extra cost if I only use my computer for work email and documents?

Probably not. Email and document work do not push the processor hard, so you will not feel the speed difference. The M4 will handle these tasks when ready. Save the money unless you also do photo or video work.

Does the M5 have better graphics than the M4?

The M5 models with more graphics cores are faster at drawing images and rendering 3D. If you do graphic design or video work, this matters. For web browsing and everyday use, both are more than fast enough.

How much longer does the M5 battery last compared to the M4?

On a MacBook Air, the M5 typically adds 2 to 3 hours of real use per charge. The exact difference depends on what you are doing — video editing shows a bigger gap than web browsing. Both will last a full workday with normal use.

Can I upgrade from an M4 to an M5 later?

No. The chip is built into the computer and cannot be replaced. You would need to buy a new computer to get the M5. This is why thinking about your needs before you buy matters.
