PS4 Boasts "hUMA" And Has The 3D Edge Over Xbox One
Update: We've received the following clarification from an AMD spokesperson on this story-
"During a recent gamescom 2013 interview, an AMD spokesperson made inaccurate statements regarding the details of our semi-custom APU architectures. AMD will not comment on the Microsoft Xbox One and Sony PS4 memory architectures and will not speak for Microsoft, Sony or other AMD customers."
So, make the appropriate alterations in your head. :)
If you're interested in all sorts of technology, and you have a special interest in 3D tech, check this out-
According to a German publication (as translated by PSU), the PlayStation 4 utilizes hUMA (Heterogeneous Uniform Memory Access), and that supposedly gives Sony's system a significant edge over Xbox One when it comes to 3D.
This came from AMD Senior Product Marketing Manager Marc Diana. It's just a tad intricate:
"Xbox360 and older APUs have a unified RAM. This means that the RAM is no longer physically separated, but even though it's the same RAM chips, the system still distinct between memory partition for the different processors. You still need to copy the data between CPU partition and GPU partition, but this will be much more efficient than copying it between physically separated pools. But it's still too much latency for a CPU, GPU, CPU roundtrip.
PS4 will have hUMA wich means that you no longer need a distinction between CPU partition and GPU partition. Both processors can use the same pieces of data at the same time. You don't need to copy stuff and this allows for completely new algorithms that utilize CPU and GPU at the same time. This is interesting since a GPU is very strong, but extremely dumb. A CPU is extremely smart, but very weak. Since you can utilize both processors at the same time for a single task you have a system that is extremely smart and extremely strong at the same time.
I have no idea what any of that means, but Diana adds that all of this is a "game changer," so Sony is going in the right direction. The only question is whether or not 3D will be an oft-used feature on the PS4; one would assume it would be, what with all technology getting better over time, but 3D-enabled games haven't exactly exploded on the PS3.
What do you think?
