Intel Discloses New Itanium Poulson Features
Intel is providing new information about Poulson, its next Itanium processor by the slice.
Tukwila, the current 65nm Itanium 9300 series, is overdue for a replacement in big iron computer systems. We already know that Poulson is still scheduled for a 2012 launch, and that it will be built in 32nm, integrate 3.1 billion transistors, a 12-wide issue architecture, up to 54 MB on-die memory as well as eight CPU cores with support for eight more virtual cores via Hyper Threading.
Adding to the information disclosed early this year at the ISSCC 2011, Intel revealed at the Hot Chips conference that the processor will ship with Instruction Replay Technology (IRT) as an enhancement for RAS - and become Intel's first processor that supports Instruction Replay RAS. The technology uses a new pipeline infrastructure to detect "transient errors in execution." IRT enables Poulson to re-execute instruction and recover or avoid instruction errors.
Poulson also adds dual-domain multi-threading that finds its way into the CPU's Hyper Threading. According to Intel, the new feature will enable independent front and backend pipeline execution, improve the efficiency of multi-threading and squeeze more performance out of the chip. Additionally, Itanium is getting new instructions to enhance integer operations, as well as higher parallelism and multi-threading capabilities with expanded data access hints, expanded software prefetch and thread control.

I'm impressed.
When I build a server I would definitely use one of these.
Hey Intel, if you read these forums I'll test one for you!

lol who wouldn't be willing to test upcoming products?

Some how doubt you will as Itanium uses a different architecture than your average desk top!
Test, yes. Buy, no. Itaniums are very expensive to use in a configuration that offers any benefit over a regular cluster of zeon multi-core servers (especially when work out the benefit to cost ratio and factor in their TCO).
With all the major manufacturers of software designed to benefit from the Itanium pulling the plug on future development of their products for the platform it won't be long before the Itanium becomes nothing much more than a footnote in Intel's 'for server' CPU line and is seen as nothing more than a development toy for the chip manufacturer (not that it isn't much more than that now!).
