Apple also wants to become independent from the point of view of GPUs, as well as CPUs: if it is a foregone conclusion in the mobile field, in the desktop one, where the company has a very long-lasting partnership with AMD, no. And a Commercial Times article sheds some light on the matter.
Apparently the GPUs are codenamed Lifuka and will be made with TSMC's 5nm production process (which is able to handle the order "thanks" to the tightening of the US ban on Huawei). Apparently the chips will take advantage of TBDR technology, or Tile-Based Deferred Rendering: it is a solution developed by Imagination Technologies on which the PowerVR GPUs are based, and could have to do with the intellectual property exploitation agreement signed by the two company earlier this year.
The GPU should arrive on the market by mid-2021, and is designed for Macs. Apple has even removed support for AMD cards in the ARM64 version of macOS.
The article adds that Apple is also working on two variants of its next-generation SoC:
- A14 is codenamed Sicilian, and is also made with a 5 nm production process
- A14X, codenamed Tonga, will be found in the next iPad Pro. Also at 5nm
