Dell OptiPlex 5055 Small Form Factor Owner's Manual
AMD APUs, AMD Ryzen CPUs and APUs
This topic explains about the AMD's APUs, Ryzen series of CPUs and Ryzen series of APUs.
OptiPlex 5055 is offered with either of the three variants of AMD's A-Series APUs, Ryzen CPUs or APUs.
AMD Advanced Processing Unit - APU
This topic explains AMD's Advanced processing Unit (APU)
The AMD Accelerated Processing Units (APU) are a series of 64-bit microprocessors designed aesthetically by AMD combining the capabilities of Central Processing Unit (CPU) and Graphical Processing Unit (GPU) on a single die(chip).
Features
:
- Heterogeneous System Architecture (HSA): An open-source, cross vendor set of specification allowing the integration of CPU and GPU on the same bus as CPU cores with coherent memory.
- Power Management: CPU and GPU share same power resources optimizing performance and availability.
- System Architecture Integration: Allows the GPU to be context switched, providing a multitasking environment with smart utilization of hardware resources across workloads.
- Open CL, C++: Support for Open CL and C++ language extensions.
AMD Ryzen
This topic explains about the AMD's Ryzen series of processors.
AMD's Ryzen is a series of CPUs and APUs based on Zen micro architecture. Zen System On Chip(SoC) design allows the PCIe, SATA, and USB controllers reside on same chip as CPU's cores.
Features
:
- Performance: Simultaneous multithreading (SMT) to allow execution of two threads per core, increasing the Instruction Per Cycle(IPC) thus enhancing the processing throughput.
- Power: AMD's Sense MI technology employs sensors across the chip to dynamically scaling the frequency and voltage automatically defined in processor itself allowing better use of available resources.
- Security and Virtualization: Ryzen offers Secure Memory Encryption(SME) and Secure Encrypted Vitalization(SEV) for real time memory encryption securing the system from cold boot attacks.
