A desktop experience that draws you in and keeps you there. This is the idea behind today’s iMac, and now that idea is more powerful than ever. The new iMac is packed with all-new processors, the latest graphics technologies, innovative storage and higher-bandwidth connectivity. And it all comes to life on the brightest and most colourful Retina display iMac has ever seen. So you get an even more immersive experience — and a scintillating new way to take it all in.
Powerful processor Intel’s 7th-generation i5 processor, codename Kaby Lake, is designed to make your machine faster and more efficient. Overall productivity will show improvement for flawless multi-tasking and playback of 4K Ultra-HD video will occur without delay or interruption. The processor also feature a 'Turbo Boost' that will unleash more power when you need it, so you can handle more programs and intensive tasks without your laptop slowing down.
iMac features powerful new Radeon Pro 500 series graphics that make a spectacle of everything you see. The 27-inch iMac with Retina 5K display is loaded with up to 4GB of dedicated VRAM, delivering visual effects and 3D graphics that exhibit raw power in its most polished form.
Stunning ultra-thin design
iMac's premium aluminium casing and glass display make for a stunning, modern looking machine, that looks as good as it performs. It's incredibly thin but still manages to pack a remarkable amount of high performance technology into the same amazingly thin enclosure.
The Retina display shines even more vividly on the new iMac. With 1 billion colours and 500 nits of brightness, graphics leap off the screen in a whole new light. And the pixel density is so high that you won’t detect a single one. Text is so clear and sharp, your email and documents will look smarter than ever. It’s simply the best Mac Retina display yet.
Sleeker wireless accessories
An extra sprinkle of fairy dust has been added to the wireless accessories to give them all a more spellbinding shape. The Magic Keyboard has had the cylindrical battery section removed, allowing it to lie completely flat. The Magic Mouse 2 is lighter yet sturdier and designed with an optimised base for a smoother glide.
