Apple updates the 27-inch iMac for 2020 with 10th-gen chips and a new screen

This new iMac looks like the old iMac, until you turn it on in a bright room.

Apple may be moving away from Intel chips, but it's not done with them yet. This year's iMac upgrade has just been announced, which adds Intel's latest line of processors, more RAM, improved graphics and a screen option that borrows from the Pro XDR display announced alongside the Mac Pro.

The screen has the same 5K (5,120 x 2,880) resolution and P3 colour gamut as the previous model, what's different – if you're prepared to pay £500/US$500 more – is its texture. The optional nano-texture glass option uses a process that Apple describes as 'etching the glass itself at the nanometre level' to reduce reflections and glare.

The display also now supports Apple's True Tone technology, which adjusts the colour temperature of its output to match the lighting of the room it's in.

There are Core i5, i7 and i9 options, topping out a 3.6GHz i9 that can 'Turbo Boost' up to 5GHz when not all of its cores are being used.

The max RAM has doubled to 128GB, and storage by four times to 8TB. The GPU options are an AMD Radeon Pro 5500XT or 5700 – both with 8GB of their own memory – or a 5700XT with 16GB.

Apple says that a top-spec model delivers up to 35% faster rendering in Maya using the Arnold renderer, and up to 55% faster ProRender in Cinema 4D (top) – compared to an 8-core previous-generation model with a Radeon Pro Vega 48 GPU.

Pricing begins at £1,799/$1,799 – rising to £4,899 for a model with a 10-core i9 processor, 32GB of RAM, 2TB of storage and a Radeon Pro 5700XT. Pushing the spec beyond this point gets you into money's-no-object territory – £8,799/$8,799 for an iMac with 10-core i9 processor, 128GB of RAM, 8TB of storage, a Radeon Pro 5700XT and 10 Gigabit ethernet.
