Coming back to the Xbox One architecture, the SOC is directly linked
to 8 GB DRAM and offers HDMI and Gigabit Ethernet through onboard
controllers. The SOC is also linked to the PCH Southbridge that offers
external ports such as two WiFi, HDMI IN, USB (Kinect), two SATA 2 ports
(Blu Ray / 500 GB HDD) and 8 GB NAND Flash eMMC 4.5. For audio, the
chip is backed by Microsoft’s own design that has two 128bit SIMD FP
vector cores, floating point performance 15.4 GFLOPS and special
hardware engine performance equivalent to 18G OPS.
The graphics part is the most interesting, we mentioned above the
architecture but going into details we found out that Xbox One GPU
architecture offers full DirectX 11.1 support and featuring graphics and
general purpose GPU performance of 1.31 TFlops which is an update over
the previously rumored 1.23 TFlops. This comes as an update with the 50
MHz clock boost we heard a few weeks back. The GPU churns out 1.71 G
Primitives/ second, 41 GTexels/s and the GPU is paired with three sets
of ram – DRAM access (CPU Cache Coherent) and 68 GB/s with non-CPU cache
coherent DRAM access. The GPU would also have access to high
performance eSRAM with a peak bandwidth of 204 GB/s. This confirms the
existence of a coherent or should we say uniform memory architecture on
the Xbox One which would be similar to the unified memory approach by
Sony on their PlayStation 4 console as reported previously.

Well this is it for now but we will sure to keep you updated regarding any new details for the PlayStation 4 and Xbox One.
