Yesterday, we covered how the PlayStation 4, along with unified memory access, would use hUMA which would give it a leg-up in terms of performance. It was noted that because the Xbox One didn’t have hUMA, it would see lesser performance.
However, according to a confirmed Xbox One dev on Reddit- who cited an Ars Technica article which defined hUMA as a coherent cache system and that the “CPU and GPU will always see a consistent view of data in memory. If one processor makes a change then the other processor will see that changed data, even if the old value was being cached” – the Xbox One will feature something similar to hUMA.
On receiving his first alpha kit, he look at internal white papers that and confirmed that the Xbox One implements memory in exactly the same way. He also noted that he couldn’t find a source where AMD’s senior product marketing manager Marc Diana stated that the PS4 would have hUMA and the Xbox One wouldn’t.
Considering that the technology powering both the Xbox One and PS4, at least in terms of CPU and GPU tech, is more or less the same, it would be odd if one sported such an essential feature and the other didn’t. What are your thoughts on the matter? Tell us below.
