M4 vs M3 in India: the upgrade math at a glance
Short answer: The M4 chip (Apple’s 3 nm second-generation — a tick on Apple’s silicon cadence) delivers a meaningful 20% CPU and 30–40% GPU uplift over M3. At Indian prices, the gap between equivalent M3 and M4 configurations typically runs ₹5,000–₹15,000. For most users — students, developers doing everyday coding, professionals running productivity apps — the M3 still handles everything thrown at it without breaking a sweat. The M4 pays back its premium only if your workload is compute-heavy: 4K/6K video editing in DaVinci Resolve or Final Cut Pro, large LLM (large language model) inferencing locally, or 3D rendering. If you are just browsing, running Zoom calls, writing in Notion, or editing photos occasionally, the M3 is the smarter buy.
What is actually different between M4 and M3
CPU and GPU performance
The M4 uses Apple’s second-generation 3 nm process (TSMC N3E) while M3 used the first-generation 3 nm (TSMC N3B). The main gains are in the neural engine (the dedicated chip that accelerates machine learning tasks), the GPU core throughput, and single-core CPU speed. In Geekbench 6 single-core, M4 scores roughly 3,800–3,900 versus M3’s ~3,000–3,100. In GPU-heavy workloads like ProRes video encoding, the gap is more pronounced — M4’s 10-core GPU handles export pipelines measurably faster.
For typical Indian professional workflows — Excel models, presentations, Zoom, VS Code, light Figma — neither chip is the bottleneck. The app opens, the export finishes, and you move on. The delta becomes visible only when the task genuinely saturates the processor for minutes at a time.
Unified memory ceiling
The M4 base model starts at 16 GB unified memory (shared RAM between CPU and GPU — Apple’s architecture that avoids the speed penalty of discrete graphics memory transfers). The M3 base started at 8 GB. This alone is a reason to prefer M4 for anyone considering future-proofing — 8 GB on an M3 MacBook Air can feel constrained with multiple heavy browser tabs, Slack, and a design tool running simultaneously. M4’s 16 GB base changes that calculus.
The India price and channel context
Indian Apple Store pricing includes 18% GST embedded in the MRP. Authorised resellers (Imagine, iStore, Croma, Reliance Digital) frequently offer ₹3,000–₹8,000 off on M3 stock as it phases out, and Flipkart/Amazon sales have historically knocked 5–8% off MacBook prices around major sale events. Grey market pricing on M3 post-M4 launch can be ₹8,000–₹15,000 below MRP, though with no Apple India warranty. The effective price differential between a new M4 and a discounted M3 from an authorised channel is typically ₹10,000–₹20,000 — real money that changes the upgrade calculus for value-conscious buyers.
GST-registered businesses purchasing a MacBook as a business asset can claim 18% GST as Input Tax Credit (ITC) — the mechanism by which registered businesses offset their GST liability. At a MacBook price of ₹1,20,000, that is approximately ₹18,300 in claimable credit. Combined with MacBook’s strong resale value (typically 60–70% of purchase price after three years), the total cost of ownership comparison versus equivalent-spec Windows laptops is closer than sticker prices suggest.

India recommendation: who should buy which
Buy M3 if
Your primary uses are college work, office productivity, light photo editing, or software development in standard languages. At a lower price, M3 gives you Apple’s build quality, macOS reliability, excellent battery life (14–16 hours real-world), and at least five more years of OS support. If you are upgrading from an Intel MacBook (2019 or earlier) or a Windows laptop, even the M3 will feel dramatically faster — the jump from Intel to Apple silicon is a larger leap than M3 to M4. Also consider reading our guide on MacBook battery cycles before buying a used M3.
Buy M4 if
You regularly edit 4K or 6K footage in Final Cut Pro or DaVinci Resolve, run large LLM models locally (Llama 3 70B, Mistral 7B inference), work in 3D tools (Blender, Cinema 4D), or need the 24 GB or 32 GB unified memory options. The M4’s neural engine improvements also make Apple Intelligence (Apple’s on-device AI features in macOS) run faster and more reliably — relevant if that feature set matters to your workflow.
A note from the LRW Engineer Team
On the repair and servicing side, newer Apple silicon generation means newer board components — M4 board repairs, when needed, typically cost 10–15% more than M3 equivalents simply due to part availability timing. This is not a reason to avoid M4, but it is worth factoring into a 4–5 year ownership cost model. We service both M3 and M4 MacBooks — battery replacement, keyboard, liquid damage, and screen repair across all current models.
