Pentium microprocessors – P-IIILaunched February 1999 - Available in speed levels of 450, 500, 550, and 600MHz .25 Micron Manufacturing Process 32KB of Level 1 Cache (operating at CPU's full core speed) 512KB of Level 2 Cache (operating at ½ of CPU's core speed) 100 MHz front-side bus speed MMX supportThe branch prediction/recovery pipeline was doubled to include 10-stages from the P-II. Pentium microprocessors – P-IIIThe next generation of microprocessors from Intel.Pentium 4 is the product of a serious redesign.The move from Pentium II to Pentium III added two million transistors.The Pentium 4 sports a whopping 42 million - 14 million more than the currently available Pentium III Coppermine processors. (Actually, 55 million for redundancy/reliability.) Pentium microprocessors – P-4The Pentium 4 is significantly larger than its predecessor. The P4 was first etched using the same .18-micron, aluminum trace process as the P-III Coppermine. The current P4 etching is the .13-micron process Now that the Pentium 4 is upon us the pipeline depth has been doubled once again to 20 stages - NetBurst microarchitecture .By doubling the depth of the branch prediction pipe, the penalty associated with mis-predictions is greatly increased. This results in a lower average number of instructions successfully executed per clock cycle. Pentium microprocessors – P-4To compensate for the lower IPC, Intel has implemented:Execution Trace Cache Dynamic Execution Engine A 32-bit microprocessor, hyper-pipelined technology, a rapid execution engine and a quad-pumped 100MHz-system bus, delivering the equivalent of 3.2GB/s of bandwidth- three times the bandwidth of the Pentium IIIIt transfers data at the equivalent of 400MHz bus speedPentium microprocessors – P-4Pentium microprocessors Level 2CacheLevel 1CachePentium IIILogic circuitsPentium microprocessors Level 2CacheLevel 1CacheIncreased logic circuitsCacheThe next generation of P4 processors will use .09 microns trace process technology.That is 90 nanometers (90 billionths of a meter)We are beginning to reach the limits of Silicon based chips.Next step may be nanotechnology Pentium microprocessorsPentium microprocessors The
