    • CPU

      The CPU in the Xbox One is similar to the one found in the PS4. Both are made by AMD and include an integrated GPU, making up AMD's definition of an APU. The console's CPU has 8 cores (4 modules), with two cores and shared cache in each module. One module contains two x64 cores, each operating a single thread at 1.6 GHz. The cores each have a 32KB instruction cache and a 32 KB data cache, and the 4 cores in each build share a 2MB level 2 caches. As a sum the builds have 8 hardware threads and 4 MB of L2. The CPU cores are clocked at running 1.6 GHz; this is half the clock rate of the Xbox 360, which might allude that the Xbox 360’s cores could outperform the new console. But this is not true do to the fact that the new console will have out of order execution between cores. This means that the CPU can re-order the micro-operations this improves performance by allowing the console to Start loads and stores as easy as possible to avoid stalls. It allows for execution of instructions in data-dependency order. Furthermore, fetching instructions from branch destination as soon as the branch address is resolved [5] .
