You can get a top-notch 5K Retina iMac right now, but if you wait until December, you could get the iMac Pro with all its advanced pro-y-ness. What to do?
The 2017 iMac is brighter, faster, and more powerful than any iMac previously available. It's powered by the fastest Kaby Lake processor, has USB-C ports, and faster storage than ever before. But, is this the Mac for you, or do you need something with even better graphics, even more memory, and even faster processing? Because if you do, the iMac Pro is coming this December and might be worth the wait.
Better graphics vs. advanced graphics
The 21.5-inch iMac comes standard with Intel Iris Plus Graphics 640. You can upgrade to Radeon Pro 555 with 2GB of VRAM or Radeon Pro 560 with 4GB of VR Ram. At its base level, the graphics in the 2017 21.5-inch iMac are ... fine. You're not going to be able to render 3D graphics or play graphics heavy games. It's perfect if you're just using your Mac to browse the internet, watch YouTube videos, or play decent graphics games. It'll take care of most people's everyday computing needs.
The 27-inch iMac comes standard with Radeon Pro 570 with 4GB of VRAM. You can upgrade to Radeon Pro 575 with 4GB of VRAM or Radeon Pro 580 with 8 GB of VRAM. It's bigger and better with VR gaming support, faster processing, and the ability to handle some fairly heavy gaming. Latency and lag are much improved and you can successfully get your MMORPG on with very little issues. It's great for complex music and video editing project, app building, and 3D graphic rendering.
The iMac Pro sports the fastest Radeon Pro Vega graphics processor (3X faster than any previous iMac GPU). It also supports double-wide graphics cards. It has higher frame rates for the most power hungry graphics activities, like VR gaming, 3D editing, and much more. The Vega can fetch data up to 4000GB per second. It's powerful enough to allow you to create VR from scratch.
If your computing needs involve standard internet activities, plus some basic, but not too extreme video, photo, or music editing, you should take the plunge and buy the current model iMac (if you do a lot of graphics editing, might I suggest the 27-inch iMac).
If you spend most of your waking hours building 3D models, developing graphics heavy games, or rendering VR maps, you should wait until December to invest in the iMac Pro Read more..
