AMD targets mobile graphics with Mullins and Beema SoCs
Dead set on getting a piece of the high end graphics-intensive embedded consumer and mobile market, Advanced Micro Devices released the first two devices in a new family of graphics SoCs.
Released are the Mullins and Beema SoCs, which feature a switchable graphics mode to optimize performance and power, with almost double the graphics performance as the previous generation.
Built around the company's Graphics Core Next Architecture (GCN), Beema runs at 800MHz iand Mullins at 500 MHz in Mullins. To decrease latency, they incorprate a video encode block next to the display interface.
They feature up to four x86 “Puma+” CPU cores and AMD Radeon R Series graphics processors based on Graphics Core Next (GCN) architecture and have been optimized for low power consumption without sacrificing image quality or performance.
Uniqjue in the semiconductor industry as one chip vendor who builds processors based on both the x86 and ARM architectures, AMD has taken advantage of that in this new set of devices to incorprate what it is calling a platform secuity processor (PSP0 that uses ARM's TrustZone silicon IP to provide additional security for the X86-based processors.
It has done this by partitioning the new processors into two "virtual CPUs," a secure one or a normal mode depending on the type of data processed. To achieve additional power savings, the chips incorporate a silicon temperature tracking algorithm which makes possible up to 63% performance increases on key workloads, without necesarrily increasing power cuncumption.
The new chips come with more efficient peripheral logic and support for DDR3-1866 DRAM, allowing their use in high performance fanless tablets. The new processors also include support for gesture control, facial recognition, and a virtual Android OS using technology from BlueStacks.
