Processor Sony VPCZ21M9E (VPCZ21M9E)
Processor speed: 
The clock rate typically refers to the frequency at which a chip like a central processing unit (CPU), one core of a multi-core processor, is running and is used as an indicator of the processors speed. It is measured in clock cycles per second or its equivalent, the SI unit hertz (Hz). The clock rate of the first generation of computers was measured in hertz or kilohertz (kHz), but in the 21st century the speed of modern CPUs is commonly advertised in gigahertz (GHz). This metric is most useful when comparing processors within the same family, holding constant other features that may impact performance.

Processor: A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer. The four primary functions of a processor are fetch, decode, execute and writeback.

Processor boost frequency: Turbo Boost is automatic. It will scale up the frequency by itself as and when required while keeping it from overheating. You can not control it yourself, but you do not need to, it works very reliably by reducing the frequency when you do not need it to save power and increasing it when you need it to give you more performance.

Processor core: A multi-core processor is a single computing component with two or more independent actual processing units (called "cores"), which are the units that read and execute program instructions. The instructions are ordinary CPU instructions such as add, move data, and branch, but the multiple cores can run multiple instructions at the same time, increasing overall speed for programs amenable to parallel computing. Manufacturers typically integrate the cores onto a single integrated circuit die (known as a chip multiprocessor or CMP), or onto multiple dies in a single chip package.

Processor threads: Hyper-threading was Intels first attempt to bring parallel computation to consumer PCs. It debuted on desktop CPUs with the Pentium 4 HT back in 2002. The original Pentium 4 had just a single CPU core, so it could only do one thing at a time - but hyper-threading attempted to make up for that.

System bus data transfer rate:

Processor cache: A CPU cache is a cache used by the central processing unit (CPU) of a computer to reduce the average time to access data from the main memory. The cache is a smaller, faster memory which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches, including instruction and data caches, where the data cache is usually organized as a hierarchy of more cache levels (L1, L2, etc.).

Processor socket: In computer hardware, a CPU socket or CPU slot comprises one or more mechanical components providing mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows for placing and replacing the CPU without soldering.

Processor cache type: CPU caches are small pools of memory that store information the CPU is most likely to need next. Which information is loaded into cache depends on sophisticated algorithms and certain assumptions about programming code. The goal of the cache system is to ensure that the CPU has the next bit of data it will need already loaded into cache by the time it goes looking for it (also called a cache hit). A cache miss, on the other hand, means the CPU has to go scampering off to find the data elsewhere. This is where the L2 cache comes into play � while it�s slower, it�s also much larger. Some processors use an inclusive cache design (meaning data stored in the L1 cache is also duplicated in the L2 cache) while others are exclusive (meaning the two caches never share data). If data can�t be found in the L2 cache, the CPU continues down the chain to L3 (typically still on-die), then L4 (if it exists) and main memory (DRAM).

PCI Express configurations: PCI Express, technically Peripheral Component Interconnect Express but often seen abbreviated as PCIe or PCI-E, is a standard type of connection for internal devices in a computer. Generally, PCI Express refers to the actual expansion slots on the motherboard that accept PCIe based expansion cards and to the types of expansion cards themselves. PCI Express has all but replaced AGP and PCI, both of which replaced the oldest widely-used connection type called ISA.

Processor operating modes: The x86 has been extended in many ways throughout its history, remaining mostly backwards compatible while adding execution modes and large extensions to the instruction set. A modern x86 processor can operate in one of four major modes: 16-bit real mode, 16-bit protected mode, 32-bit protected mode, and 64-bit long mode. The primary difference between real and protected mode is in the handling of segments: in real mode the segments directly address memory as 16-byte pages, whereas in protected mode the segments are instead indexes into a descriptor table that contains the physical base and size of the segment. 32-bit protected mode allows paging and virtual memory as well as a 32-bit rather than a 16-bit offset.

Stepping: Stepping level refers to the introduction or revision of the lithographic photomask or masks within the set of plates that generate the pattern that produces an integrated circuit. The term originated from the name of the equipment ("steppers") that exposes the photoresist to light. Integrated circuits have two primary classes of mask sets, base layers that are used to build the structures that make up the logic such as transistors, and metal layers that connect the logic together.
