My goal is just to have a community where people can go and see what new game news is out for the day and comment on it.
Other communities:
From the description it kind of reminds me of the performance gains seen in the 1990s when the industry moved from direct geometry calls to using display lists to cut down on the number of times the GPU is waiting for instructions.
One of the big reasons the ps5 usually beats out the Xbox hardware, despite worse hardware by the numbers, is because of this kind of thinking.
They built a custom ssd controller that the gpu has direct access to. This means when something needs to happen involving the ssd and gpu, the gpu can just directly access the memory it needs to without needing to wait on the cpu.
Just let the gpu do what it does best without having to wait on the cpu, and everything is going to go so much smoother.
Isn't this how DMA works?
Eh in a way, dma is like the cpu offloading to another chip. What sony did is make the gpu not need the cpu to use dma
At some point... do you need the CPU? There's stuff it will be better at, yes, and more power is always better. But the GPU can run any code.
The whole computer outside the video card could be reduced to a jumped-up southbridge.
GPUs are ridiculously, ludicrously good at doing an absolute shit-ton of very simple, non-dependent calculations simultaneously. CPUs are good at... Well, everything else. So yes, you do still need the CPU.
GPUs are really terrible at the kind of multitasking required to run an OS
Fuck me for playing what-if, apparently.
Not like this news is explicitly about upending the typical CPU-GPU relationship.
