Xbox One Chip Slower Than PlayStation 4@ 2013/05/24
PlayStation 4 chip, which came to light this February, is truly an engineer's fantasy. It combines eight "Jaguar" 64-bit x86 cores clocked at 1.60 GHz, with a fairly well spec'd Radeon GPU, which features 1,156 stream processors, 32 ROPs; and a 256-bit wide unified GDDR5 memory interface, clocked at 5.50 GHz. At these speeds, the system gets a memory bandwidth of 176 GB/s. Memory isn't handled like UMA (unified memory architecture), there's no partition between system- and graphics-memory. The two are treated as items on the same 8 GB of memory, and either can use up a majority of it.
