CPU-Z
CPU-Z is a software to find out some important information about the main components of a PC / laptop computer or us, a case of processor (CPU), cache, mainboard, memory (RAM), and SPD. For those whose hobby brain-tweaking a PC, happy air overclocking experiments and hobbies, must be familiar with this CPUZ. Software with a small size is quite sophisticated and accurate when the processor recognizes that we use, such as your name and number, size, speed, multiplier, clocks, etc.. On the mainboard tab, we can see information about the VGA, BIOS, chipset etc.. while on the memory tab, displayed information modules, frequency, serial number, is very useful if we want to upgrade or replace memory. =)
CPU-Z is a software that monitors and gives us information on devices that exist in our PC. This software monitors:
CPU
* Name and number.
* Core stepping and process.
* Package.
* Core voltage.
* Internal and external clocks, clock multiplier.
* Supported instructions sets.
* All cache levels (location, size, speed, technology).
Mainboard
* Vendor, model and revision.
* BIOS model and date.
* Chipset (northbridge and southbridge) and sensor.
* Graphic interface.
Memory
* Frequency and timings.
* Module (s) specification using SPD (Serial Presence Detect): vendor, serial number, timings table.
System
* Windows and DirectX version.

>>Now, this is information in the first tab, "CPU"
Name: Clarifies the name / label processor.
Code name: a processor code from the company that manufactures the processor.
Package: socket type used for the processor. eg Sokeet P, LGA 771, LGA 775, PAC418 Technology: includes information on the transistor technology used.
Specification: specification details of the physical processors.
Instruction: is the kind of instruction that can controlled by the processor.
MMX
Initially, the term MMX MultiMedia reportedly is short extension or Multiple Math or Matrix Math extension. But the Intel officially rejected the notion, saying that MMX is not short for anything. MMX is the trademarked (brand / trademark) of Intel, which contains an understanding of the increased compression and decompression processor in video, image manipulation, encryption, processing Input / Output.
MMX technology is designed and patented by Intel Corporation. Was first introduced in January 1997 that applied to the Pentium processor is then referred to as "Pentium with MMX Technology '.
MMX was actually a set of SIMD instructions. With SIMD implementation, allows the chip processor executing commands repetitive or parallel rapid, especially when the processors run the commands associated with video, audio, graphics, and animation. Technically, it is explained that into the design of this MMX technology, Intel is adding eight new registers in the processor architecture. Registers are MM0 to MM7. In fact, this new register is another name of the x87 FPU register stack that already exists.
SSE (Streaming SIMD Extension) is the result of the development and refinement of MMX technology. SSE is a set of larger development of SIMD instructions, with 32 bit floating point support and the addition of sets of registers 128-bit vectors, which facilitates operation of SIMD and FPU (Floating Point Unit) in the same time.
SSE2 (short for Streaming SIMD Extensions 2) has an additional 144 new instructions.
SSE3 (Streaming SIMD Extension 3)
has 13 additional new SIMD instructions, or in other words SSE3 has 13 more than the SSE2 instructions. Additional new instructions are used to assist processing of complex mathematics, graphics, video encoding process, and thread synchronization. SSE3 Technology was given the code name Prescott New Instructions (PNI), was first implemented and introduced in the revision of Prescott processor (Pentium class 4).
SSSE3 (Supplemental Streaming SIMD Extension 3)
codenamed Tejas New Instructions (TNI) or Merom New Instruction (MNI). SSSE3 technology has been applied to the processor using the Intel Core microarchitecture, such as the Intel Xeon processor 5100 series which is a server-class processors, and Intel Core 2 processors for desktop and mobile class. SSSE3 has an additional 16 new instructions that are discrete.
EM64T (Extended Memory 64 Technology)
allows the processor to walking with a new 64-bit code and to access larger memory, which gives a great graphic performance and higher data processing speed high. Digital media applications benefit from the Intel EM64T on the process video and audio quality and also high and 3D rendering.
VT-X translate commands from the processor.
Area core clock
is information on the total clock undertaken by each core (depending on the multiplier setting in bios).
CORE SPEED
The clock rate is the rate in bits per second (measured in hertz) or the frequency of the clock in any synchronous circuit, Such as a central processing unit (CPU). For example, a crystal oscillator reference frequency is typically synonymous with a fixed sinusoidal waveform, a clock rate frequency reference Is That translated by electronic circuitry (AD Converter) into a corresponding square wave pulse [typically] for digital electronics applications. In this context the use of the word, speed (physical movement), Should not be confused with its corresponding frequency or clock rate. Thus, the term "clock speed" is a misnomer.
Multiplier Figures in cooperation with the bus speed multiplier determines how fast a CPU is executed. Multiplier 4.5 paired with a processor at 100 MHz bus speed will produce a 450 MHz CPU speed (4.5 x 100). Almost all new processors Intel has locked the multiplier that can only be run on a specific multiplier. Bus speed is a measure of independent and can be changed so that the 4.5x100 and 4.5x103 will generate a CPU that runs at different speeds (with a note that the CPU can run at that speed.)
BUS SPEED
Bus speed. The number of grooves that can executed by a processors in the second period. This time unit is measured in units of million second direction which is also known as megahertz (MHz) or million second orbit, and most computers have a bus speed of 100 to 133MHz. A bus trying to improve computer performance but it is usually tied to the speed of processors. For example using the bus 66MHz Celeron, Pentium! 100/133MHz.
QPI (Quick Path Interconnect)
QPI is a replacement bus speed of the FSB, if the FSB is the data transmission path between the chipset, processor and memory, more simply QPI. QPI is a data transmission speed of the processor to the chipset. If previously we know the Northbridge chipset as a set of processor, memory and PCI-E lane, then the Core i7 processor, chipset, known as the IOH (Input-Output Hub), which served as a line input and output of the entire system. The area is a large cache processor cache memory.
A CPU cache is a cache Used by the central processing unit of a computer to reduce the average time to access memory. The cache is a Smaller, faster memory the which stores copies of the data from the most frequently Used main memory locations. As long as most memory accesses are cached memory locations, the average latency of memory accesses will from be Closer Than to the cache latency to the latency of main memory.
When the processor needs to read from or write to a location in main memory, it first checks whether a copy of That data is in the cache. If so, the processor reads from or writes Immediately to the cache, the which is much faster Than reading from or writing to main memory.
Most modern desktop and server CPUs have at least three independent caches: an instruction cache to speed up executable instruction fetch, a data cache to speed up data fetch and store, and a translation lookaside buffer Used to speed up virtual-to-physical address translation for both executable instructions and data. Core is the number of processor cores.
L1 cache is the cache closest to the processor so that the fastest way to execute data.Ketika we are operating the computer then the data from hard drives that often we operate will be transferred to memory / RAM, and data from the memory / RAM are transferred also to the Cache on processor. Please note, if viewed in terms of time speed access by the processor, data taken from the hard drive is the slowest, followed by a memory / RAM, then the L3 cache, L2 cache and finally to the L1 Cache.Sebagai comparison, the time needed by the processor to access data from the L2 cache has a speed of 2-3 fold when compared with the taking of \ memory / RAM. Therefore cache in processor technology plays an important role in determining the speed of data access.
