Apple rolls out first update to iMac desktop in almost two years

Apple Inc introduced the first update to its iMac all-in-one desktop computer since mid-2017, continuing a hardware blitz ahead of a highly anticipated event March 25 to unveil new media and entertainment services.

The latest iMac adds speedier processors from Intel Corp and new graphics engines from AMD. The new 4K 21.5-inch models are up to 60 percent faster with 8th-generation quad-core chips, while the 5K 27-inch versions are up to 2.4 times faster with 9th-generation eight-core Intel processors, Apple said Tuesday.

The new 21.5-inch iMac will still start at $1,299, while the larger-screened model will sell for $1,799. Apple is also still selling a 21.5-inch iMac without a 4K or 5K screen for $1,099.
