What is L1 cache?
Page 19
L1 cache is memory in a computer. If the computer processor can find the data it needs for its next operation in cache memory, it will save time compared to having to get it from random access memory. L1 is “level-1” cache memory, usually built onto the microprocessor chip itself. L1 cache- 64KB
What is L2 cache?
Page 19
L2 (that is, level-2) cache memory is on a separate chip (possibly on an expansion card) that can be accessed more quickly than the larger “main” memory. A popular L2 cache memory size is 1,024 kilobytes (one megabyte).
What is L3 cache?
Page 19
L3 cache has typically been built into the motherboard, but some CPU models are already incorporating L3 cache. The advantage of having on-board cache is that it’s faster, more efficient and less expensive than placing separate cache on the motherboard. L3 cache – 4MB-12MB
What is CPU?
Page 19
CPU (pronounced as separate letters) is the abbreviation for central processing unit. Sometimes referred to simply as the central processor, but more commonly called processor, the CPU is the brains of the computer where most calculations take place. In terms of computing power, the CPU is the most important element of a computer system.
What is processor socket?
Page 19
The processor socket (also called a CPU socket) is the connector on the motherboard that houses a CPU and forms the electrical interface and contact with the CPU. Processor sockets use a pin grid array (PGA) where pins on the underside of the processor connect to holes in the processor socket.
What is LGA 775?
Page 22
LGA 775 is an Intel desktop CPU socket. LGA stands for land grid array. Unlike earlier common CPU sockets, such as its predecessor Socket 478, the LGA 775 has no socket holes; instead, it has 775 protruding pins which touch contact points on the underside of the processor (CPU)
What is LGA 1156?
Page 22
LGA 1156, also known as Socket H or H1, is an Intel desktop CPU socket. LGA stands for land grid array. Celeron G1xxx series, Core i3, i5, i7 (8xx series, Pentium G6xxx series, Xeon 34xx series.
What is LGA 1155?
Page 22
LGA 1155, also called Socket H2, is a socket used for Intel microprocessors based on Sandy Bridge and Ivy Bridge microarchitectures. It was designed as a replacement for LGA 1156
What is LGA 1150?
Page 22
LGA 1150 is designed as a replacement for the LGA 1155 socket, which is also known as Socket H2. The LGA 1150 socket has 1150 protruding pins that make contact with the pads on the bottom side of the processor
What is LGA 1366?
Page 22
Socket 1366 (Socket B) uses QPI to connect the CPU to a reduced-function northbridge that serves mainly as a PCI-Express controller. A slower DMI is used to connect Intel’s most recent northbridge and southbridge components
What is LGA 2011?
Page 22
LGA 2011 socket uses QPI to connect the CPU to additional CPUs. DMI 2.0 is used to connect the processor to the PCH. The memory controller and 40 PCI Express (PCIe) lanes are integrated on the CPU
What is Socket AM3?
Page 22
Socket AM3 is a CPU socket for AMD processors. AM3 was launched on February 9, 2009 as the successor to Socket AM2+, alongside the initial grouping of Phenom II processors designed for it. The principal change from AM2+ to AM3 is support for DDR3 SDRAM.
What is Socket AM3+?
Page 22
Socket AM3+ is a modification of the AM3 Socket designed for CPUs which use the AMD Bulldozer microarchitecture and retains compatibility with AM3 processors.The Vishera line of AMD CPUs also all use Socket AM3+.
What is Socket FM1?
Page 22
Socket FM1 is a CPU socket for desktop computers used by AMD early A-series APUs (“Llano”) processors and Llano-derived Athlon II processors
What is Socket FM2?
Page 22
Socket FM2 is a CPU socket used by AMD’s desktop Trinity and Richland APUs to connect to the motherboard as well as Athlon X2 and Athlon X4 processors based on them
