TBDR APU for desktop

Thu Jul 09, 2020 8:15 am

https://9to5mac.com/2020/07/08/arm-mac-graphics/

The track record for apples marketing regarding Mac gaming is abysmal, so spread the salt thick.

HOWEVER.... this sounds really interesting. I’ve been skeptical of the APU concept, but maybe AMD just hasn’t had the resources to implement it well.

If anybody has the resources and stack control to make this work, it’s Apple.

I’m really curious to see what the Apple Silicon that ends up in a Mac Pro looks like.

nvidia does TBR while AMD does not. I dunno if this will change with RDNA2 or not.

I used to have a Kyro II video card that works this way and it could punch above its weight class very often.
And btw, the company that made the chipset used in the Kyro II is the grand daddy of the chips used in Adreno and other ARM mobile chips video system.
In the end this is nothing new.

Adreno was ATI. Kyro was PowerVR/Imagination.

Some background:

https://www.anandtech.com/show/4686/sam ... defined/15

TL;DR -- there are other approaches that involve tiles and early rejection, but they aren't TBDR.

TBDR is really an Imagination technology, and Apple's GPUs are either based on, or heavily influenced by, Imagination tech (https://www.anandtech.com/show/15272/im ... -agreement).

Found very good information about ARM Mac graphics performance.
