Would have been interesting for Ars to have asked them how their GPU differs from the IMGTec/PVR IP they acquired besides adding more cores, what did they change?
They give the impression by saying it’s a custom GPU that it’s a from scatch in-house design but it’s unlikely to be the case.
- sweden 8y agoThe GPU they were licensing from Imagination was already very tailored to their needs. Apple already had a strong saying in the architecture, in the driver, in the compiler and in the implementation details of the GPU they were buying from them. Moving to a "custom GPU" was basically Apple saying "Ok, thanks, we are taking over from here".
- microcolonel 8y agoIdunno, the PVR-based products were pretty awful, drivers were full of system crashing bugs which could be triggered by reasonable shaders (On two separate occasions, I accidentally wrote shaders which would crash iOS and cause it to restart). I haven't touched their recent products, but I suspect they have been working on this stuff for a long time, because I think it'd be pretty hard to put up with that crap for any longer.
