![]() In this case, you’d be able to feel powerful speakers in the desk. Big traditional speakers are made of wood because wood is good at absorbing these vibrations. The concept of force-opposing speakers is that, because speakers need to move lots of air, and Newton’s Third Law exists, when you vibrate your driver in one direction to move air, there’s a resulting vibration that escapes into whatever holds the speaker. Force-opposing drivers are used to cancel out residual vibrations from powerful speakers, so you can put loud and impactful sound into something where you don’t want shaking to happen – they’re used in high-end subwoofers for home cinema, and in Apple’s 16-inch MacBook Pro, as well as here. The really clever part is the use of two woofers in each side, positioned exactly to oppose each other (one facing forward, one back). ![]() There are six drivers in total, with three in each of the bottom corners. The speakers are one of the most interesting upgrades. There’s also now a better array of mics that Apple describes as ‘studio-quality’, which will always remain as slightly wishful thinking when the average home office is lacking several other crucial qualities that studios have, but should still help to pick your voice and avoid other sounds around you. It also includes a ‘Neural Engine’, which can be used by apps that include machine learning tools to massively speed up tasks – this is niche, but some Mac apps are starting to make good use of it.Īt the top is a 1080p Full HD webcam, which uses the M1 chip for image processing, though doesn’t include the useful ‘Center Stage’ feature that the iPad Pro (2021) does, disappointingly, which keeps you in the middle of frame even if you move around – Apple pushes this iMac as being as much for the kitchen or living room as an office desk, and this would be a really useful feature. The M1 also provides graphics, with seven or eight cores of GPU power depending on the model you choose. You can get it with 8GB or 16GB of RAM – a drop from the 32GB max that the older model offered, which will be annoying for some pro users, though isn’t a problem for the average buyer. That’s an eight-core processor, with four high-power performance cores and four lower-speed 'efficiency' cores. The screen has always been one of the big draws for iMacs, because you don’t find a huge number of 21- to 24-inch 4K displays at all, let alone at this level of quality… and if you do, they cost most of what this entire machine costs, without adding all the actual computer parts.įor power, you’ve got the Apple M1 chip in an iMac for the first time, replacing the Intel processors and graphics used in the previous model. ![]() You also get Apple’s True Tone system, which adjusts the colours based on the lighting in your room, and makes a big, big difference for eye comfort, in our experience. The screen offers 500 nits of typical brightness, and P3 wide colour gamut support both of which are big improvements on your average monitor, which is likely to be about half as bright, and without such wide colour support. Easy! Apple has done 24-inch screens before, but not since 2009, so this is a blast from the past. ![]() Let’s start with the screen, which is a 23.5-inch, 4480x2520 display – Apple is calling this ‘4.5K’, which makes sense if you know that 4K just means ‘any screen around 4000 pixels wide’. Not a single aspect remains unchanged in some way. What’s new in the 24-inch iMac compared to the 21.5-inch model it replaces? Literally everything.
