manufacturer amd k6-2
The ___MASK63___ System / 360 introduced byte - addressable memory with 8 - bit bytes , as opposed to bit - addressable or decimal digit - addressable or word - addressable memory , although its general purpose registers were 32 bits wide , and addresses were contained in the lower 24 bits of those addresses . Different models of System / 360 had different internal data path widths ; the ___MASK63___ System / 360 Model 30 ( 1965 ) implemented the 32 - bit System / 360 architecture , but had an 8 bit native path width , and performed 32 - bit arithmetic 8 bits at a time . 3DNow ! is an extension to the x86 instruction set developed by ___MASK25___ ( AMD ). It adds single instruction multiple data ( SIMD ) instructions to the base x86 instruction set , enabling it to perform vector processing , which improves the performance of many graphic - intensive applications . The first microprocessor to implement 3DNow was the AMD K6 - 2 , which was introduced in 1998 . When the application was appropriate this raised the speed by about 2 - 4 times . The 8086 ("" eighty eighty - six "", also called iAPX 86 ) is a 16 - bit microprocessor chip designed by ___MASK84___ between early 1976 and mid - 1978 , when it was released . The ___MASK84___ 8088 , released in 1979 , was a slightly modified chip with an external 8 - bit data bus ( allowing the use of cheaper and fewer supporting ICs ), and is notable as the processor used in the original ___MASK63___ PC design , including the widespread version called ___MASK63___ PC XT . The K6 - 2 was an x86 microprocessor introduced by AMD on May 28 , 1998 , and available in speeds ranging from 266 to 550 MHz . An enhancement of the original K6 , the K6 - 2 introduced AMD ' s 3DNow ! SIMD instruction set , featured a larger 64 KiB Level 1 cache ( 32 KiB instruction and 32 KiB data ) , and an upgraded system - bus interface called Super Socket 7 , which was backward compatible with older Socket 7 motherboards . It was manufactured using a 0 . 25 micrometre process , ran at 2 . 2 volts , and had 9 . 3 million transistors . A front - side bus ( FSB ) was a computer communication interface ( bus ) often used in ___MASK84___ - chip - based computers during the 1990s and 2000s . The competing EV6 bus served the same function for AMD CPUs . Both typically carry data between the central processing unit ( CPU ) and a memory controller hub , known as the northbridge . The Super Socket 7 , also referred to as Super 7 , is an extension of the Socket 7 ZIF socket specification . It features a 100 MHz front - side bus , support for AGP , and a SPGA package . Super Socket was used by AMD K6 - 2 and K6 - III processors , some of the final Cyrix M - II processors , some of the final IDT WinChip 2 processors , and Rise mP6 processors . It is backward compatible with Socket 7 , meaning a Socket 7 CPU can be used with a Super Socket 7 motherboard , but a Super Socket 7 CPU cannot operate at full speed in a Socket 7 motherboard . Socket 5 CPUs are pin - compatible with Super Socket 7 , but not all motherboards designed for Super Socket 7 supported the voltages needed for Socket 5 CPUs . ___MASK25___ , Inc . ( AMD ) is an American multinational semiconductor company based in Sunnyvale , California , United States , that develops computer processors and related technologies for business and consumer markets . While initially it manufactured its own processors , the company became fabless after GlobalFoundries was spun off in 2009 . AMD ' s main products include microprocessors , motherboard chipsets , embedded processors and graphics processors for servers , workstations and personal computers , and embedded systems applications . ___MASK84___ Corporation ( also known as ___MASK84___ , stylized as ___MASK84___ ) is an American multinational corporation and technology company headquartered in Santa Clara , California ( colloquially referred to as " Silicon Valley ") that was founded by Gordon Moore ( of Moore ' s law fame ) and Robert Noyce . It is the world ' s largest and highest valued semiconductor chip makers based on revenue , and is the inventor of the x86 series of microprocessors : the processors found in most personal computers ( PCs ). ___MASK84___ supplies processors for computer system manufacturers such as Apple , Lenovo ( formerly ___MASK63___ ), HP , and Dell . ___MASK84___ also manufactures motherboard chipsets , network interface controllers and integrated circuits , flash memory , graphics chips , embedded processors and other devices related to communications and computing . Socket 5 was created for the second generation of ___MASK84___ P5 Pentium processors operating at speeds from 75 to 120 MHz as well as certain Pentium OverDrive and Pentium MMX processors with core voltage 3 . 3 V . It was released in March 1994 . Consisting of 320 pins , this was the first socket to use a staggered pin grid array , or SPGA , which allowed the chip ' s pins to be spaced closer together than earlier sockets . Socket 5 was replaced by Socket 7 . The Rise mP6 was a superpipelined and superscalar microprocessor designed by Rise Technology to compete with the ___MASK84___ Pentium line . Socket 7 is a physical and electrical specification for an x86 - style CPU socket on a personal computer motherboard . It was released June 1995 . The socket supersedes the earlier Socket 5 , and accepts P5 Pentium microprocessors manufactured by ___MASK84___ , as well as compatibles made by Cyrix / ___MASK63___ , AMD , IDT and others . x86 is a family of backward compatible instruction set architectures based on the ___MASK84___ 8086 CPU and its ___MASK84___ 8088 variant . The 8086 was introduced in 1978 as a fully 16 - bit extension of ___MASK84___ ' s 8 - bit based 8080 microprocessor , with memory segmentation as a solution for addressing more memory than can be covered by a plain 16 - bit address . The term " x86 " came into being because the names of several successors to ___MASK84___ ' s 8086 processor end in " 86 ", including the 80186 , 80286 , 80386 and 80486 processors . The ___MASK84___ 8088 ("" eighty - eighty - eight "", also called iAPX 88 ) microprocessor is a variant of the ___MASK84___ 8086 . Introduced on July 1 , 1979 , the 8088 had an 8 - bit external data bus instead of the 16 - bit bus of the 8086 . The 16 - bit registers and the one megabyte address range were unchanged , however . In fact , according to the ___MASK84___ documentation , the 8086 and 8088 have the same execution unit ( EU ) only the bus interface unit ( BIU ) is different . The original ___MASK63___ PC was based on the 8088 .
