XBOX One APU, cannot understand Microsoft decision on making the GPU. (rant)

ShaunCabrera · Mar 24, 2015

Why does the APU feature using 12 of 14 CUs of the GCN. In any case it is said that will improve yield. Would it be better if it went with the total 14CUs and go for 1Ghz of the GCN in the APU for better Memory Bandwidth. I think in my opinion that it was
a dumb move to pull of a 6.6% frequency boost to the GPU of 12CUs. Way-to-go Microsoft.

I am still a BIG FAN of Microsoft Operating systems and their gaming consoles, good costumer service and gaming.

XBOX One APU, cannot understand Microsoft decision on making the Graphics (Rant)

The GPU has 14 CU but only 12 are used. The other 2 are redundant because enabling them would mean that they cant be guaranteed to work on every chip produced, due to manufacturing faults on the chip.

Why does the APU of XBOX One feature using 12 of 14 Compute Units? In any case what does it mean to improve yield? Would it have been a better decision than a 6.6% frequency boost to the GPU by using all the Compute Units clocked a 1Ghz? Way-to-go Microsoft.

No need to make duplicate threads about the same subject.

There's already one in the xbox one discussion forums.

This is a very complex issue.... Especially when you factor in the upcoming directx 12...

You can always add more power, the question is can you use it with the bandwidth you have. The PS4 has more power and is optimised to use it. And it shows mostly.

I'd argue that the xbox one hardware is optimised to use direct x12 and has been patched up to deliver with the current software. DX 12 is a new approach to how graphics are processed so it's hard to judge where the xbox one sits in terms of real capabilites.
I'm sure that's where all this talk of a balanced system comes from. Phil himself has said that they were well aware of direct x12 when they designed the xbox one and the xbox one offers full support for dx12.

I'm excited.....

This probably comes as close to an answer pre directx12 as you will get.

It can be seen as a safety net or less thought in compatibility of components by design, Either a bad decision or a safe decision.
