Each chipset hosts up to 8 cores, equipped with a 256 KB primary cache, as well as a secondary cache
of up to 24 MB, an I/O processor, a memory controller, and a system controller.
2 GHz Dual Core Cortex A9 Processor with 1MB Secondary Cache
For $11,500, SGI's Fuel comes with a 700-MHz MIPS R16000 processor (or the 600-MHz MIPS R14000A processor), with 4MB secondary cache
plus up to 4 GB system memory.
The penalty of a primary cache miss that hits in the secondary cache
is at least 12 cycles, and the total penalty of a miss that goes all the way to memory is at least 75 cycles (plus any delays due to contention, which is modeled in detail).
Each server will have two Itanium processors at 733 MHz, 2MB secondary cache
per CPU, 4GB of SDRAM memory and 36GB of disk space.
Evaluating stream buffers as a secondary cache
Configured with Intel's 440BX chipset and the Intel Pentium III processor, the system has high clock speeds plus a 256KB on-chip secondary cache
, further improving performance of Microsoft Office applications.
The amount of memory you have on your PC will have a noticeable effect on your computer's performance, regardless of the processor speed, There are three types of memory that you should be concerned with: RAM (at least 32MB); secondary cache
memory (256K) and video RAM (2MB).
The new systems will ship standard with 1MB secondary cache
, 128MB RAM, 9GB hard disk, 32X CD-ROM drive, 17-inch monitor, keyboard and mouse.
The R12000 boosts the clock speed of the MIPS processor up to 300MHz from the R10000's 250MHz, and doubles the size of the secondary cache
The EPC-10 is a dual slot PC/AT-compatible board with VMEbus and a complete set of features that include: two 144-pin SODIMM sockets, 512K secondary cache
, auto-sensing 10/100 Base T Ethernet controller on-board with front panel RJ45 connector, fast SCSI II controller on-board with front panel connector, two USB ports via front panel, two serial ports and one parallel port, mouse and keyboard controllers and an EXMbus expansion.
5 operating system, 1MB of secondary cache
, 128MB of memory (2GB maximum), 4GB ultra-fast SCSI hard disk and a 20-inch monitor.
