<!-- Image with disputed fair-use status removed: [[Image:IBM_logo.svg|thumb|128px|IBM logo]] -->The '''POWER6''' microprocessor is [[IBM]]'s follow-on to the [[POWER5]].

POWER6 was described at the [http://www.isscc.org/isscc/ IEEE International Solid-State Circuits Conference] (ISSCC) in February 2006, and additional details were added at the Microprocessor Forum in October 2006[http://www.in-stat.com/FallMPF/06/] and at the next ISSCC in February 2007. It was formally announced on 21 May 2007 [http://www-03.ibm.com/press/us/en/pressrelease/21580.wss]. As of October 2008, POWER6 is the fastest microprocessor in the industry at per-core basics.<ref>{{cite web

The POWER6 has approximately 790 million transistors and is 341 mm² large fabricated on a [[65 nanometer|65 nm]] process. It was released on the 8th June 2007, at speeds of 3.5 [[GHz]], 4.2 GHz and 4.7 GHz<ref name="IBM">{{cite web

The processor is a [[dual core]] design and has 128 [[KiB]] of [[L1 cache]] (64 KiB data + 64 KiB instruction), an eight-way set-associative design with a two-stage pipeline supporting two independent 32-bit reads or one 64-bit write per cycle.<ref name="informationweek">{{cite web

Each core has two [[Arithmetic logic unit|integer units]], two [[binary|binary]] [[floating point unit|floating-point unit]]s, and a novel [[decimal|decimal]] floating-point unit, and is capable of two way [[Simultaneous multithreading|SMT]]. The binary floating-point unit incorporates “many microarchitectures, logic, circuit, latch and integration techniques to achieve [a] 6-cycle, 13-FO4 pipeline,” according to a company paper.<ref name="informationweek"/> Unlike the servers from IBM's competitors, the POWER6 has hardware support for [[IEEE 754]] decimal arithmetic and includes the first decimal [[floating-point]] unit integrated in silicon. More than 50 new floating point instructions handle the decimal math and conversions between [[Binary numeral system|binary]] and [[Binary-coded decimal|decimal]].<ref name="Heise"/> This is a feature also added to the processors powering IBM's [[ZSeries|System z]].<ref name="realworld1">{{cite web

There is an [[AltiVec]] unit to POWER6, and the processor is fully compliant with the new [[Power Architecture#Power ISA v.2.03|Power ISA v.2.03]] specification. POWER6 also takes advantage of [[IBM ViVA|ViVA-2]], '''Vi'''rtual '''V'''ector '''A'''rchitecture, which enables the combination of several POWER6 nodes to act as a single [[Vector processor]].<ref name="realworld1" />


What do you wanted to say to me?[[User:Max Mux|Max Mux]] ([[User talk:Max Mux|talk]]) 21:28, 5 October 2008 (UTC)
A notable difference from [[POWER5]] is that IBM moved from an [[Out-of-order_execution|out-of-order]] design to an in-order design, a change which often requires software recompilation for optimized performance. However, the processor still achieves significant performance improvements even with unmodified software, according to the lead engineer on the POWER6 project.<ref name="theregister">{{cite web

== ROC ==
IBM also makes use of a 5 GHz duty-cycle correction clock distribution network for the processor. In the network, the company implements a copper distribution wire that is 3 µm wide and 1.2 µm thick. The POWER6 design uses dual power supplies, a logic supply in the 0.8-to-1.2 Volt range and an SRAM power supply at about 150-mV higher.<ref name="informationweek"/>. The thermal characteristics of POWER6 are similar to that of the [[POWER5]].


Retired Officers List (2000):
POWER6 can connect to up to 31 other processors using two inter node links (50 GB/s), and supports up to 1024 virtual partitions.<ref name="Heise"/> POWER6 comes in [[Multi-Chip Module|MCM]]s just like POWER5 with up to four processor dies and associated external L3 cache on a single substrate. There is an interface to a service processor that monitors and adjusts performance and power according to set parameters.<ref name="eetimes">{{cite web

IBM Power Systems run on the Power 6 CPU. The systems are the 520 Express, 550 Express, Power 570, Power 575, and Power 595. Power systems running AIX vs i have different model designations but the hardware is essentially identical. [[Power Systems]].[http://www-03.ibm.com/systems/power/hardware/]. The various system models are designed to serve any sized business. For example, the 520 Express is marketed to small businesses while the Power 595 is basically a mainframe. All Power systems are noted for their huge expansion and storage capabilities.

IBM also offers two Power 6 based single wide blade servers, the JS12 and the JS22. [[Blade server|blade module]].[http://www-03.ibm.com/systems/power/hardware/blades/index.html] The JS12 is equipped with (2) 3.8GHz Power 6 cores while the JS22 has (4) 4.0GHz Power 6 cores. Both blades support AIX, i, and Linux. The BladCenter S and H chassis is supported for blades running AIX, i, and Linux. The BladeCenter E, HT, and T chassis support blades running AIX and Linux but not i.


Hello. Based on your recent comment at [[Wikipedia:Articles for deletion/Alaska Seaplane Service]], I thought you might be interested in looking at [[Wikipedia:Articles for deletion/Alsek Air Service]]. -- [[User:Zyxw|Zyxw]] ([[User talk:Zyxw|talk]]) 15:17, 7 October 2008 (UTC)
At the SuperComputing 2007 (SC07) conference in Reno a new water-cooled p575 was also revealed with 32 POWER6 cores at 4.7 GHz with up to 256 GB of RAM.
