Sorry for my paraphrasing...
Nvidia have been talking a lot lately, AMD finally gave a response lol.
...And though Sony spent more time talking about the PS4's DualShock controller than AMD's chippy contributions at the conference, Neal Robison, director of ISV relations at AMD, was more than happy to lay it out for TechRadar.
"It's not just about an x86 solution, but it's about that Jaguar APU where it's a combination of the graphics and CPU together and being able to create something that's greater than just putting an x86 PC-like architecture together," Robison explained.
"[Sony's] approach - and they've said this publicly over the last couple of days here at GDC - was, 'We looked at some of the ways that we approached hardware in the past, and we wanted to improve.' And they looked at us as being able as being able to provide that."
AMD could provide an integrated solution through its APU that Nvidia couldn't, he continued, by optimizing information flows, generating greater performance, better power and heat efficiency, and by providing tools and dev relationships to provide the PS4 a strong launch.
In a recent interview with TechRadar, Nvidia's Tony Tamasi sized up the PS4's specs to "a low-end CPU, and a low- to mid-range GPU" when compared to gaming PCs. The console's innards, Tamasi said, are outdated even now, months before the PS4 launches during the 2013 holiday season.
"Well, of course they're going to do that," Robison said with a laugh when told of the comparison. "They're a little bitter."
"For us, really by looking at that APU that we designed, you can't pull out individual components off it and hold it up and say, 'Yeah, this compares to X or Y.'
"It's that integration of the two, and especially with the amount of shared memory [8GB of GDDR5, 176GB/s raw memory bandwidth] that Sony has chosen to put on that machine, then you're going to be able to do so much more moving and sharing that data that you can address by both sides.
Thanks to the Gaf for braking it down
