Intel Itanium 9500 through 9700 series
Itanium 9500 (Poulson): 2012
The Itanium 9500 series processor, codenamed Poulson, the follow-on processor to Tukwila was released on November 8, 2012. According to Intel, it skips the 45nm process technology and uses a 32nm process technology. It features eight cores and has a 12-wide issue architecture, multithreading enhancements, and new instructions to take advantage of parallelism, especially in virtualization. The Poulson L3 cache size is 32 MB. L2 cache size is 6 MB, 512 I KB, 256 D KB per core. Die size is 544 mm², less than its predecessor Tukwila (698.75 mm²).
At ISCC 2011, Intel presented a paper called "A 32nm 3.1 Billion Transistor 12-Wide-Issue Itanium Processor for Mission Critical Servers."Given Intel's history of disclosing details about Itanium microprocessors at ISSCC, this paper most likely referred to Poulson. Analyst David Kanter speculated that Poulson would use a new microarchitecture, with a more advanced form of multithreading that uses up to two threads, to improve performance for single threaded and multithreaded workloads. Some information was also released at the Hot Chips conference.
Information presented improvements in multithreading, resiliency improvements ( Intel Instruction Relay -RAS) and few new instructions (thread priority, integer instruction, cache prefetching, and data access hints).
Intel's Product Change Notification (PCN) 111456-01 lists four models of Itanium 9500 series CPU which was later removed in a revised document.The parts were later listed in Intel's Material Declaration Data Sheets (MDDS) database.Intel later posted Itanium 9500 reference manual.
The models are the following:
9520 4 Core/ 8 Threads 1.73 GHz 20MB cache
9540 8 Core/16 Threads 2.13 GHz 24MB cache
9550 4 Core/ 8 Threads 2.40 GHz 32MB cache
9560 8 Core/16 Threads 2.53 GHz 32MB cache
Itanium 9700 (Kittson): 2017
Rumors of a successor to Poulson (code named Kittson) began to circulate in 2012–2013. This was at first associated with a forthcoming 22 nm process shrink, and later revised in the face of declining Itanium sales to a less-ambitious 32 nm node. In April 2015, Intel, although it had not yet confirmed formal specifications, did confirm that it continued to work on the project
Intel officially launched the Itanium 9700 series processor family on May 11, 2017.Notably, Kittson has no microarchitecture improvements over Poulson, only higher clock speeds.
The models are:
9720 4 Core/ 8 Threads 1.73 GHz 20 MB cache
9740 8 Core /16 Threads 2.13 GHz 24 MB cache
9750 4 Core/ 8 Threads 2.53 GHz 32 MB cache
9760 8 Core/ 16 Threads 2.66 GHz 32 MB cache
