1. Presentation on Intel product (processors) Presented to: Sir Imran Hanif Presented by: Muhammad Arshad Bs(cs)4 th Roll#06-36

2. Developmental History of Main-Line Intel CPUs

3. Intel 4004 specs Introduced in November of 1971 Was the first microprocessor 108 KHz clock speed Four bit adder A sixty-four bit index register An address incriminator And an eight bit instruction register and decoder

4. Intel 8086/8088 Introduced on June 8, 1978 First commercially successful 16 bit processor Too expensive for early computers, so the 8088 was developed with an 8 bit bus 8088 and 8086 ensured success of Intel corporation, because they were they start of the *86 family that was the basis for every IBM compatible PC

5. 8086 specifications clock speeds of 5 MHz, 8MHz, and 10 MHz The 8086 could address 1 Meg of memory, while the 4004 could only address 640 bytes the 8086 had fourteen registers –general registers, segment registers, index registers, status and control register 16 bit processing power

6. Intel 80186 High Integration 16-bit Microprocessor fifteen to twenty of the most common microprocessor system components, providing twice the performance of the 8086 while operating at the same clock speed strategic flaw in the 80186 –released in early 1981 Intel believed that all computer manufactures would follow IBM’s lead and incorporate a built in DMA and timer chip

7. 80186 Specifications ten more instructions to the op code set of the 8086 two different modes for the 80186 to run in –Enhanced –Standard

8. Intel 80286 Released of February of 1982 80286 shipped at slightly faster clock speeds than the 80186 80286 introduced protected mode memory addressing –Allows programmers to access memory above 1 meg –Virtual memory becomes a possiblility up to 1 Gig

9. Intel 80386SX/DX First truly mass market processor with 32-bit addressing. Able to address 4 gigabytes of RAM, and 64 terabytes of virtual memory. Delivered performance ranging from 5 MIPS in the first 16 MHz model to 11.4 MIPS in the fastest 33Mhz model Offered real mode, protected mode, and a ability to run many “virtual” real mode sessions simultaneously 275,000 Transistors with a 1-micron process.

10. Intel 80486SX/DX 1.2 Million Transistors with a 1 micron process Performance ranges from 20 MIPS in the 25 MHz DX model to 70.7 MIPS in the 100 MHz DX4 model DX model contained math co-processor and 8K L1 Cache Could address 4 gigabytes of RAM and 64 terabytes of virtual memory. DX2 version allowed the core of the processor to run at twice the bus speed. DX4 version allowed the core of the processor to run at three times the bus speed.

11. Intel Pentium Processor Name was chosen to thwart companies like AMD, Cyrix, etc. 3.1 Million Transistors using.8 micron process 4 GB RAM/64 TB Virtual Memory 64-Bit Data Bus Superscalar Design – had hardware for simultaneous instruction execution 66 MHz bus speed Double the amount of L1 cache: an 8 KB instruction cache and an 8 KB data cache More advanced math co-processor

12. Pentium error – look-up tables MMX – multimedia extensions Pentium MMX ran at a core voltage of 2.8v instead of the normal Pentium’s core voltage of 3.5v Pentium MMX done with.35 micron process Intel Pentium Processor

13. Intel Pentium Pro Originally called “P6” L2 cache was available in 256 KB, 512 KB, 1 MB, and 2 MB versions, and ran at full clock speed Clock speeds ranged from 166 to 200 MHz, with bus speeds of 60 and 66 MHz Ran on Socket 8 connector, which was the only socket the Pentium Pro supported Support for up to 4 processors in parallel Ran much better in NT Laid groundwork for future Intel processors.

14. The Pentium II processor Released May 1997, the second P6 architecture chip from Intel Used new socket called “Slot 1” Originally ran at 233 and 266 MHz The creation of a new motherboard made just for the PII, the i440LX, allowed for greater processing speeds In October 1997 the 300 MHz processor was produced and the 333 MHz, called the “Deschutes,” a few months later Deschutes was the first chip to implement.25 micron technology, previously.35 micron

15. Pentium II (Can't) Next Came the 350 and 400 MHz processors The first processors to introduce a 100 MHz front side bus April 1998 another motherboard was released, which led to the last Pentium II chip Running at 450 MHz with 512 KB of cache memory running at one half clock speed

17. The Celeron processor In an attempt to regain the loses in the sub $1000 computer market, the Celeron processor was produced in early 1998 Based heavily on the Pentium II, except was without the level 2 cache and plastic casing The removal of the casing allowed for easier cooling, but having no level 2 cache SEVERLY reduced speed. Originally ran at 266 and 300 MHz Finally in August 1998 the Celeron A was introduced It had only a quarter the level 2 cache (128 MHz) of the Pentium II, but was implemented entirely different

18. The Pentium II Xeon processor June 29, 1998 the Pentium II Xeon processor was released to the public The processor was geared solely toward the high- end workstation and server market. It was not for home or personal use since servers often require a chip more powerful than 512 MB The Xeon was also built on the Deschutes core The level 2 cache was made with different chips called “CSRAM” (Custom Standard RAM), which was made specially by Intel Required extreme cooling so it had a very large casing

19. Xeon (Can't) The Xeon had some other special features -Can support up to 8 CPUs in one system -The cache was limited at 64 GB, done through 36-bit address bus -Runs a 100 MHz front side bus with a maximum band width of 800 MB/sec -Contains a built in thermal sensor -Used a new kind of ROM called PIROM which stantds for processor information ROM -This made the processor much more flexible to specifications

20. The Pentium III processor The Pentium III was to the Pentium II what the Pentium MMX was to the original Pentium Released in February 1999 Equipped with 70 new instructions to improve 3D and multi- media applications Main difference between the PIII and the other Pentiums was that it implemented the SSE instructions, which accelerates floating-point instructions over the display adapter

21. The Pentium IV processor The latest processor produced by Intel and also the fastest, from 1.6 to 2.4 GB Implements the Intel® NetBurst™ architecture –A 400 MHz system bus brought achieved through a physical signaling scheme of quad pumping the data transfers over a 100-MHz clocked system bus and a buffering scheme –Uses SSE2 which extends the old SSE with 144 new instructions, including 128 bit integer and floating point calculations, and an added data movement register was also added which improves both floating point and multimedia applications
