Types of Processors Intel Xeon Intel Itanium2 AMD Opteron G5 MIPS High Performance Processors SPARC

 RISC microprocessor originally designed by Sun Microsystems  SPARC processor contains as many as 128 general purpose registers  The UltraSPARC IV has a clock frequency of 1.05 – 1.2 GHz and a 16 MB L2 cache

Intel Xeon MP  Intel NetBurst® Microarchitecture with 400 MHz system bus  Hyper-Threading Technology: Hardware support for multi-threaded server applications  Rapid Execution Engine  Streaming SIMD Extensions 2 (SSE2)  Integrated Level 3 Cache (4MB, 2MB, or 1MB)

Intel Itanium 2  Explicitly Parallel Instruction Computing (EPIC)  6MB L3 integrated cache, 256KB L2 cache, 32KB L1 cache  Enhanced Machine Check Architecture (MCA) with extensive Error Correcting Code (ECC)  Floating point architecture: Speeds up complex calculations  Target software segments: Databases, High Performance Computing, Security Transactions, Software Engineering and Network Edge

MIPS  MIPS designs are used in SGI's computer product line, embedded systems, Windows CE devices, and Cisco routers.  The Nintendo 64 console, Sony PlayStation2 console use MIPS processors.  The latest MIPS processor has a core frequency of 600 MHz a computer bus speed of 200 MHz an a L2 cache of 8 MB

AMD Opteron  AMD64 Core  Simultaneous 32- and 64-bit computing capabilities  Direct Connect Architecture  Integrated DDR DRAM Memory Controller  Hyper Transport Technology  Cray, Inc. announced that they will create a supercomputer using 10,000 AMD Opteron processors which will have a theoretical peak performance of 40 TFlops

G5  The PowerPC G5 microprocessor has over 58 million transistors on it and it incorporates IBM's 90 nanometer fabrication process.  The processor is manufactured with SOI technology, and IBM's additive-copper to be used in chip wiring.  The G5 64-bit processor has a RAM capacity of eight gigabytes.  G5 has a "superscalar, superpipelined" execution core that can handle up to 216 in-flight instructions, and uses a 128-bit, 162-instruction SIMD unit.  Virginia Tech built a super computer using 1100 G5 dual processors!!!
