It's always fascinating to see what Apple brings to the table with their new silicon, and the M4 chip is no exception. While the M4 iPad Air might not be a flashy redesign, the internal upgrades are where the real story lies, especially when we start comparing its performance.
For those keeping score, the M4 chip is built on a more modern 3-nanometer process compared to the M1 Max's 5-nanometer. This isn't just a technical detail; it translates directly into tangible benefits. In benchmarks, the M4 shows a significant lead, particularly in single-core performance. For instance, in Geekbench v6, the M4 (10-Core) boasts a 55% advantage over the M1 Max, hitting 3777 points compared to 2431. This means that for everyday tasks, apps that rely heavily on a single core, and general responsiveness, the M4 feels noticeably snappier.
When it comes to multi-core performance, the M4 also pulls ahead, though the gap narrows slightly. In Cinebench R23, the M4 (10-Core) scores 13471, a respectable 9% improvement over the M1 Max's 12411. This suggests that while the M4 is a powerhouse for demanding applications that can utilize all its cores, the M1 Max still holds its own in heavily threaded workloads.
But where the M4 truly shines is in its efficiency. The numbers here are quite striking. In Cinebench 2024, the M4 delivers 40.9 Performance Per Watt (PPW), dwarfing the M1 Max's 15.8 PPW. Similarly, in Geekbench 6 Multi-Core, the M4 achieves 617.4 PPW compared to the M1 Max's 253.5 PPW. This improved efficiency is crucial for portable devices like iPads, meaning longer battery life and less heat generation, even when pushing the chip hard.
It's worth noting that the M1 Max still holds an edge in integrated graphics, with its 32-core GPU offering a higher TFLOPS count and supporting more RAM. So, for the absolute most graphically intensive tasks, especially those that can leverage the M1 Max's broader memory bandwidth, it might still be the preferred choice. However, the M4's integrated graphics are still very capable, and its overall performance gains, coupled with its remarkable efficiency, make it a compelling upgrade. The M4's faster neural engine also hints at future AI capabilities, which will be interesting to see unfold.
Beyond raw processing power, the M4 iPad Air also sees an upgrade in its connectivity. The move away from Qualcomm modems to Apple's own N1 wireless and C1X 5G chips is a significant step. Early tests show the C1X delivering impressive speeds, even outperforming some flagship phones in 5G tests, reaching download speeds of up to 593 Mbps. This means faster downloads, smoother streaming, and a more reliable connection on the go.
Ultimately, the M4 chip represents a smart, iterative evolution for Apple's silicon. It's not about reinventing the wheel, but about refining it to be faster, more efficient, and better prepared for the future, especially in areas like on-device AI processing. For many users, this translates into a smoother, more responsive experience, whether they're using their device for productivity, creativity, or simply staying connected.
