21.5-inch iMac with Retina 4K display: 3.0GHz quad-core Intel Core i5
A desktop experience that draws you in and keeps you there. This is the idea behind today's iMac. Faster and more powerful than ever, iMac is now equipped with seventh-generation Intel Core i5 and i7 processors and the latest high-performance graphics. 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 8GB of dedicated VRAM. Storage is about space. But it's also about speed. A Fusion Drive gives you the best of both worlds. The Retina display shines even more vividly on the new iMac. With one billion colours and 500 nits of brightness, graphics leap off the screen in a whole new light. The world is full of spectacular colours, and iMac brings more of them to your screen. The Retina display uses P3 colour that shifts away from standard white LEDs to advanced red/green phosphor LEDs. Two Thunderbolt 3 (USB-C) ports come standard on all iMac models, each delivering up to 40 Gbps data transfer for external drives and cameras and twice the bandwidth for video and display connectivity.
