Letters, numbers, even computer instructions might be positioned into memory with equal ease. Because the CPU doesn’t differentiate between several types of information, it’s the software’s duty to give significance to what the memory sees as nothing but a collection of numbers.

Testing carried out by Apple in February 2019 using preproduction 3.2GHz 6-core Intel Core i7-primarily based 21.5-inch iMac systems with Radeon Pro Vega 20 graphics with 4GB of VRAM and 32GB of RAM, as well as preproduction three.6GHz 8-core Intel Core i9-based mostly 27-inch iMac techniques with Radeon Pro Vega forty eight graphics with 8GB VRAM and 64GB of RAM; and delivery 3.6GHz quad-core Intel Core i7-based mostly 21.5-inch iMac methods with Radeon Pro 560 graphics with 4GB VRAM and 32GB of RAM, as well as delivery four.2GHz quad-core Intel Core i7-based mostly 27-inch iMac techniques with Radeon Pro 580 graphics with 8GB VRAM and 64GB of RAM. OsiriX MD v.10.zero.2 examined utilizing a CT scan dataset with 1300 slices of 512 x 512 voxels.
