不清楚,不過這裡寫的是28nm http://www.engadget.com/2013/05/21/xbox-one-hardware-and-specs/
Processor and graphics: as rumored, a heavily customized AMD chip that combines an eight-core CPU, a GPU tailored for DirectX 11.1 graphics and 32MB of high bandwidth embedded ESRAM memory. The 28nm chip will consume around 100 watts, which is slightly higher than current Xbox Slim and PS3, but Microsoft promises noise from the cooling fans will be "four times quieter." 作者: 高达八成 时间: 2013-5-22 12:03
