May 7 news, future versions of Intel code-named "Tukwila" Itanium processor has conducted a number of changes. In the concept version of the chip during the chip has changed names twice, but did not determine the number of cores, possibly even 4 to 32 cores. However, it seems that Intel made a final decision, which will use the Itanium chip, 4 cores.
According to theregister.co.uk website reported that the sources pointed out that the Itanium chip, Intel's decision to design smaller and faster with the number of cores rather than a greater number of low-power core, people in more than a year time has been looking forward to confirm four core Intel Itanium processors. Using four core Intel chip design will provide users with better single thread, so Intel's Itanium processor performance between IBM Power6 processors and faster Sun Microsystems Rock 16 core processing between devices.
Tukwila chip with Intel that it has accepted an increase in the chip memory controller and code-named "CSI" (Common System Interconnect bus) serial interconnect technology ideas. Real World Technologies in Asia Conference on High Performance Computing at Intel's presentations received after the disclosure of such information.
According to reports, Tukwila processor market in 2008. This processor uses a chip on the FB-DIMM memory controller. This memory controller can reduce the delay. FB-DIMM memory controller can support four channels of memory, it may support more channels of memory. Owing to the reduced memory latency, Tukwila processor cache capacity needs than the previous Itanium chip is less.
Code-named "Montecito" dual-core Itanium processor, a 27MB cache configuration, while the Tukwila processor is said to only 6MB 3 cache per core, or the processor chip has 24MB cache. The first chart shows that the four core chip and and each cache has a control communication between the switch.
Tukwila processor, the first code name "Tanglewood", originally released in 2007. Tukwila processor end chip design should allow Intel to catch up with rivals in many aspects, such as on-chip memory controller and the use of more cores simultaneously handle multiple software threads and so on.
