Apple has demonstrated impressive graphical performance brand ARM-based chipsets that will be used in Macs in the example of the game Shadow of the Tomb Raider during WWDC 2020. Many were shocked by how smoothly the game worked in the Rosetta 2. During a session for developers, the company explained how to port applications with a proprietary Metal API to work on the chips Apple A-series.
The developers have presented something called “deferred rendering tile-based” (TBDR). According to experts from Gizmodo, this technology is vastly superior to what currently offer for its graphics chips, Intel, NVIDIA and AMD. TBDR captures the entire scene before the GPU starts to render, thus splitting it up into several small fragments, which are processed in parallel, so the chipset does not need high memory bandwidth.
The use of IMR technology used in modern GPUs from other manufacturers, immediately handles the whole scene, which as you might guess, is much less effective and requires high memory bandwidth. In addition to the advantages in speed, Apple’s solution more and significantly more energy-efficient.
It is not known whether Apple to offer its customers a discrete video adapters third party when you purchase a Mac after a full transition to their own ARM chips. In developer documentation, the company said: “do Not think that a discrete graphics processor means better performance”, which can be interpreted as a hint of coming rejection of the adapters from other manufacturers.
