Failure of equipment suppliers and software developers to reach an understanding with deciding the fate of Intel Itanium processors questioned the bright future of these solutions. However, Intel is actively working on a new, tenth Itanium generation , which is also known under the code name of Poulson. Some details about these processors have already been discussed .
Associate was able to examine the document entitled Itanium Processor 9500 Series: Reference Manual, which contains a bunch of previously unknown information about Poulson.
Thus, processor chip Poulson, will be known as the Itanium 9500, has 3.1 billion transistors, which in turn form eight cores. Also Poulson includes two arrays of shared cache memory, two memory controllers Scalable Memory Interconnect (SMI), supporting up to 512GB DDR3 memory per slot, 5-channel bus QPIc. Chip area is 588 square millimeters.
Poulson has a total of 54 MB cache memory: 32 MB L3 cache , split between the core of 8 blocks 4 MB, 2 MB L2 cache, 4MB L2 Cache, 2.2 MB directory cache, 3.6 MB last level, and tags 169 KB second-level tagging instructions. Each Poulson core has 16KB data cache and 16KB instruction cache. The entire cache supports error correction code.
In the central part of the crystal there is a 10-channel router, which manages memory and I / O system, as well as four channels of QPI links at the top with the two halves channel at the bottom. Last assist in creating computers with up to eight sockets for processor Itanium.
In comparison with Tukwila, previous-generation Itanium, Intel engineers in Poulson transistor budget efficiently dispose for each core to have 89 million transistors (109 million in Tukwila). The width of conveyor was doubled to 12 teams and retained compatibility.
Intel will present up to four processors Poulson: Itanium 9520, Itanium 9540, Itanium 9550, 9560 and Itanium. Their debut will take place in this year . Related Products :
