I think he means on RAM issues. The PS3 only had 256 shared DDR3 Ram, but the PS4 has 8GB of GDDR5 memory. The GPU cand CPU are the only bottlenecks that could hurt the PS4..... in 2018

The CPU/GPU aren't exactly bottlenecks. Will they be weak in 5 years? Yes, but they won't be bottlenecks unless you are trying to port a game made for $5000 uber-PCs to the PS4.

It's not about how weak/strong something is down the line. A weaker CPU to a, relatively, stronger GPU can bottleneck a set-up. This can happen out of the gate. I just don't imagine that it will and this guy is mainly speaking about the balanced architecture of the system. Bottlenecks can still ahppen, no matter, though.

Are you saying the CPU inside the PS4 is too weak to handle the GPU? It's not a high-end CPU but I'm sure they went with it for a reason. If the CPU was a bottleneck, they woulndn't have went with it. Guerilla Games wouldnd't have gone on record saying PS4 has no performance bottlenecks. I think some early proof that what he is saying is true is by looking at the Killzone ShadowFall demo. Some website(maybe Digital Foundry) did an analysis of the trailer and it seemed to be running at a constant 30FPS. No performance dips.
If you saw early PS3/360 games or even Wii U games, there were performance issues. Why? Bottlenecks. Developers still hadn't found ways around them.
|
What exactly was the bottleneck from your understanding in 360's design?
|
Computers in general aren't very efficient and are full of bottlenecks. The Xbox 360 is built just like a typical computer as in they pick a CPU, pick a GPU...etc and put it into the system. These components weren't designed to work with each other. In fact they're made by different companies. IBM CPU w/ AMD GPU. That's why we're seeing next-gen consoles going with an APU design. The CPU and GPU in there are designed to make full use of each other. This is why it doesn't matter that we're not getting the GTX 680 or whatever in these consoles. It would be a lot more inefficeint, hot and bulky.
If you asked me this question back in 2005, I wouldn't have been able to tell you. It is 2013 though and the most obvious bottleneck is the RAM.
|
No, it wasn't. This applies to the first Xbox but not 360. The IBM PPC is a custom design, exclusively built for MS with some aspects of the Cell. The GPU from AMD is also very custom as the whole design was because of the rather new approach of unified memory which now PS4 and NextBox will use. And yes, retrospective it is easy to recognize bottlenecks although I don't know why it is RAM by 360. It could have more RAM, yes, but it wasn't a bottleneck by your definition.
|
Can you really call it unified memory when the system relies on 10mb of eDRAM though? The eDRAM is used to get around the bottleneck that is the main RAM. This is why the PS4 config is so good, it doesn't need eDRAM or eSRAM. It is truly UNIFIED. Also since this is a console I think Sony made the right choice in using GRAPHICS DOUBLE DATA RATE version 5.
GDDR5 is defined as high performance RAM designed for computer applications that require high bandwidth.(LIke Games)
