  • HANDOUT – CPU Explained Objective 101.04
    HANDOUT – CPU Explained Objective 101.04 What is a CPU? The CPU, Central Processing Unit, is the brain of the PC. It may also be referred to as the processor or central processor. A CPU is really a microprocessor or MPU that is made up of millions of transistors on a silicon wafer. The transistors act like tiny switches that are either turned on or off. The CPU uses these switches to execute a sequence of stored instructions called a program. There are four basic processes in the execution of instructions: 1. Fetch 2. Decode 3. Execute 4. Write-back. All the work done by a CPU is done using binary numbers – either a 1 or a 0. The 1 is the switch in the on position causing a presence of voltage, and the 0 is the switch in the off position causing an absence of voltage. The CPU has an Arithmetic Logical Unit or ALU that performs arithmetic and logical operations on the binary numbers. The CPU also has a Control Unit that extracts instructions from the memory, decodes and executes the instructions. CPU Manufacturers Intel IBM used to control the PC industry and market. IBM worked with a company called Intel, which manufactured CPUs for IBM. Over time, Intel has become the world leader in microprocessor development. Intel develops their chips, which fall into generations or families. The first generation was the 8080, 8088, and the 8086 chips. The next generation was the 80286, 80386, and 80486 chips. The next family was the Pentium 1, Pentium Pro, P2, P3 and P4 microprocessors.

  • AMD EPYC 7002 Architecture Extends Benefits for Storage-Centric
    Micron Technical Brief AMD EPYC™ 7002 Architecture Extends Benefits for Storage-Centric Solutions Overview With the release of the second generation of AMD EPYC™ family of processors, Micron believes that AMD has extended the benefits of EPYC as a foundation for storage-centric, all-flash solutions beyond the previous generation. As more enterprises are evaluating and deploying commodity server-based software-defined storage (SDS) solutions, platforms built using AMD EPYC 7002 processors continue to provide massive storage flexibility and throughput using the latest generation of PCI Express® (PCIe™) and NVM Express® (NVMe™) SSDs. With this new offering, Micron revisits our previously released analysis of the advantages that AMD EPYC architecture-based servers provide storage-centric solutions. To best assess the AMD EPYC architecture, we discuss the EPYC 7002 for solid-state storage solutions, based on AMD EPYC product features, capabilities and server manufacturer recommendations. We have not included any specific testing performed by Micron. Each OEM/ODM will have differing server implementation and additional support components, which could ultimately affect solution performance. Architecture Overview The new EPYC 7002 series of enterprise-class server processors, AMD created a second generation of its “Zen” microarchitecture and a second- generation Infinity Fabric™ to interconnect up to eight processor core complex die (CCD) per socket. Each CCD can host up to eight cores together with a centralized I/O controller that handles all PCIe and memory traffic (Figure 1). AMD has doubled the performance of each system-on-a- chip (SoC) while reducing the overall power consumption per core through advanced 7nm process technology over the first generation’s 14nm process, doubling memory DIMM size support to 256GB LRDIMMs while also providing a 2x peripheral throughput increase with the introduction of PCIe Generation 4.0 I/O controllers.
