Differences between Intel-based Macs vs Apple Silicon (M1/M2/M3): what to choose?

Are you considering buying a Mac computer but not sure whether to choose an Intel-based or Apple Silicon model? Apple's transition to its own chips has raised many questions about performance, compatibility, and practical differences. Let's explore in detail how these platforms differ and when to prefer one over the other.

Performance: Apple Silicon's big win

Apple Silicon chips brought a remarkable performance leap to the market. The M1 was already more powerful than most Intel processors, but the newer M-series chips are even more impressive.

Processor (CPU) performance:

• M4 shows 34-48% better performance in single-core tests compared to competing x86 processors, with single-core performance 48-66% better than Intel/AMD flagships
• M4 cores feature a completely new architecture and are significantly faster than those of the original M1 – CPU core performance has increased by 62% between generations
• M-series chips uniquely feature efficiency cores (for example, M4 uses 4 performance cores + 6 efficiency cores), which handle routine work in a battery-efficient manner, while performance cores activate for more demanding tasks

Graphics processor (GPU) performance:

• M4 Max can show a 541% better result in Blender rendering than M1 Max
• M1 Max offers 10 TFLOPS of GPU power, while M4 Max reaches 16 TFLOPS
• M3 Ultra even exceeds AMD Radeon 6900XT performance in Geekbench Metal tests and is 85% more powerful than the M2 Ultra in GPU performance

The comparison is especially impressive considering that Apple's chips achieve all this with significantly lower energy consumption.

Compatibility: does everything work?

Apple Silicon uses ARM architecture, which differs from Intel's x86 architecture. This means that not all applications may work right away.

Application compatibility:

• Most popular applications have already been optimized for Apple Silicon
• Rosetta 2 translation technology allows most Intel-based applications to run on Apple Silicon computers, though some performance loss may occur
• Photoshop, Final Cut Pro, Logic Pro, and other professional creative applications are now optimized for Apple Silicon

Creative work plugin compatibility:

• Compatibility with older audio plugins and VSTs may be an issue, especially for more specific or less frequently updated tools
• Specific video applications and add-ons may need updating or may not work at all
• Fortunately, compatibility issues have decreased year by year, but it's worth checking the compatibility of your essential plugins before purchasing

Specific limitations:

• Apple Silicon GPUs lack native FP64 (double-precision floating-point) support, which may be important in scientific computing and specific scientific applications
• Virtualization solutions have improved, but running Windows through Boot Camp is no longer possible – Windows must be run through a virtual machine

Battery life and heat: revolutionary change

Apple Silicon brings a significant advantage in battery life and heat dissipation, which is especially noticeable in everyday use.

Battery life:

• Apple Silicon laptops offer up to twice the battery life compared to Intel models
• M-series chips use energy much more efficiently, consuming only 2-20W of power even in high-performance computing tasks
• M4 can achieve 2.9 TFLOPS at 20W, while NVIDIA RTX 4090, for example, needs 174W for tensor tasks

Heat and cooling:

• Apple Silicon laptops run remarkably cooler, and many models don't even need a fan
• Intel models tend to heat up significantly during demanding tasks, and fan noise is common
• Measurements show that M-series chips demonstrate 0.46 TFLOPS/W efficiency, which means much less heat dissipation compared to Intel solutions

Longevity: which is the smarter investment?

Apple is clearly committed to developing Apple Silicon, which raises questions about the longevity of Intel-based Macs.

Software support:

• Intel-based Macs are gradually losing software support as Apple focuses increasingly on its own chips
• Apple Silicon currently receives priority for new features and optimizations
• macOS updates increasingly focus on leveraging Apple Silicon capabilities, gradually leaving Intel models behind

Investment value:

• The aftermarket value of Intel-based Macs has declined more rapidly since the introduction of Apple Silicon
• Apple Silicon models currently retain their value better as they are technologically more current and represent Apple's future direction

When is buying an Intel Mac worth it?

Despite the advantages of Apple Silicon, there are situations where an Intel Mac might be a sensible choice:

1. Need for specific applications: If you use applications that aren't optimized for Apple Silicon and they are critical to you (such as older professional tools)
2. Boot Camp necessity: If you need the ability to run Windows directly (not virtualized) and this is essential in your workflow
3. Budget: Used Intel Macs are often more affordable, especially older models that may be perfectly adequate for everyday tasks

When is buying an Apple Silicon Mac worth it?

Apple Silicon is clearly the better choice when:

1. Battery life is important: Long workdays without a charger or frequent movement between different workplaces
2. Performance is a priority: M-series chips offer the best performance in most applications, especially considering energy efficiency
3. Future-proofing: Apple's development clearly focuses on the Apple Silicon platform, so you'll get the latest features and software updates for longer
4. Quiet work environment: Minimal heat dissipation and fan noise make the work experience much more pleasant

Transition: what to consider?

If you're considering transitioning from Intel Mac to Apple Silicon, it's worth considering the following aspects:

1. Check compatibility of essential applications – most are already adapted, but exceptions exist, especially with older software or niche products
2. Consider memory specifics – Apple Silicon uses a unified memory architecture that works differently from traditional solutions but is generally more efficient
3. Consider a used Apple Silicon Mac – you get newer technology but save compared to a brand new device

From UPGREAT's selection, you can find quality used Intel and Apple Silicon Macs that have been thoroughly checked and come with a 2-year warranty. If you already prefer Apple Silicon, our selection includes various M1 and M2 series models that offer excellent performance at a reasonable price.

Additionally, it's worth thinking about getting a suitable monitor and keyboard-mouse to maximize your Mac computer's potential. It's also important to have the necessary adapters and cables, especially when transitioning from one platform to another.

Summary

Apple Silicon offers significant advantages in performance, battery life, and future-proofing. However, Intel-based Macs may be sensible choices in certain special cases or if you find a good deal. If you're looking for the best value for money, it's worth considering used devices that are professionally checked and come with a warranty.
