Carmack happy with PS4 system specs

Industry veteran and id Software designer John Carmack has only kind things to say about the just-announced PlayStation 4. Writing on Twitter, Carmack said he is pleased with the specifications for Sony's next-generation platform.

"I can’t speak freely about PS4, but now that some specs have been made public, I can say that Sony made wise engineering choices," he said.

Carmack's commented last year on next-generation platforms, saying he was "not all that excited" about these consoles. He noted Microsoft and Sony are too focused on boosting technical power, when they should instead be working on building new experiences for future consoles.

"Sony and Microsoft are going to fight over gigaflops and teraflops and GPUs and all this," he said at the time. "In the end, it won't make that much difference."

Sony officially announced the PS4 this week at a New York City event. The system will be available during holiday 2013 and features a custom chip that contains eight x86-64 cores and an enhanced PC GPU graphics processor.

id Software last year closed its mobile operations to focus on Doom 4 development.
