As for prices, while the entry level, relatively more affordable 21.5-inch iMac will set you back by $1,299, you will need to pay $200 more for the 4K version of the model in the same screen size.

Apple also claims to have integrated solid-state storage (SSD) that's twice as fast, though only benchmarks will prove that promise. That includes adding some more ports, an additional USB-C port to be precise. Paired with Apple's new Metal 2 engine for graphics, the new Macs are Apple's most powerful yet.

iMac also comes with a new display that is 43% brighter at 500nits and with support for one billion colors. The good news, then, is that the standard iMac has been given a welcome update.

Yes, it's a powerful system - the baseline systems ship with a 27-inch 500-nit 5K display and eight-core Intel Xeon processors, and 18-core systems can be configured.

New smart speaker expected as Apple kicks off conference
It needs to be plugged in to a physical wall socket and it's able to do a litany of tasks if you ask it - through Siri, of course. The moves announced Monday escalate Apple's technological battle of wits with Google, Amazon , Microsoft and Facebook.

'King' of the road LeBron needs win at Golden State
Cleveland coach Tyronn Lue says it's good to have Golden State coach Steve Kerr back on the sideline for the NBA Finals. Expect a closer game Sunday, as the Warriors probably won't enjoy the same plus-16 turnover margin they had in Game 1.

Marlins' Volquez throwing no-hitter through 7 versus Arizona
Volquez finally notched his first win after holding the Phillies to one run and three hits over six innings on Monday. Whit Merrifield and Mike Moustakas had two-run doubles off Carlos Carrasco (5-3) during the Royals' big inning.

The iMac Pro will have AMD Radeon Vega graphics with up to 16GB of VRAM.

This likely means that these Core i5 and i7 chips are actually Core i5-Y and i7-Y CPUs that launched with the Kaby Lake generation, meant to succeed the previous Intel Core m parts while maintaining much of the same power profile as before. The 15-inch MacBook Pro will feature standard discrete graphics with more video memory.

"It is satisfying to see the capabilities of "Radeon Pro 500" series in elegant form factors and enabling awesome content creation, gaming and VR experiences", said Raja Koduri, Senior Vice President and Chief Architect, Radeon Technologies Group, AMD, in a statement. The Radeon Pro 560 ups this to 16 compute units for 1,024 stream processors and up to 1.9 T/FLOPS of compute. And for half-precision computation, ideal for machine learning, iMac Pro delivers up to a 22 Teraflops of performance. In terms of storage, the SSD storage options are now up to 50 percent faster than the previous versions, and users can be further customized with up to 2TB of storage, Ternus said. For the first time ever on a Mac, iMac Pro features 10Gb Ethernet for up to 10 times faster networking. The upgrades to better processors happened as expected, affecting the 12-, 13- and 15-inch MacBook Pro 2017 variants.

Just like its predecessor, the 2017 MacBook weighs 2.03 pounds (920g) and measures 0.52 inches (1.31cm) at its thickest point.
