Xeon

The Xeon /ˈziːɒn/ is a brand of x86 microprocessors designed and manufactured by Intel Corporation, targeted at the non-consumer workstation, server, and embedded system markets. Primary advantages of the Xeon CPUs, when compared to the majority of Intel's desktop-grade consumer CPUs, are their multi-socket capabilities, higher core counts, and support for ECC memory.

Overview

The Xeon brand has been maintained over several generations of x86 and x86-64 processors. Older models added the Xeon moniker to the end of the name of their corresponding desktop processor, but more recent models used the name Xeon on its own. The Xeon CPUs generally have more cache than their desktop counterparts in addition to multiprocessing capabilities.

P6-based Xeon

Pentium II Xeon

The first Xeon-branded processor was the Pentium II Xeon (code-named "Drake"). It was released in 1998, replacing the Pentium Pro in Intel's server lineup. The Pentium II Xeon was a "Deschutes" Pentium II (and shared the same product code: 80523) with a full-speed 512 kB, 1 MB, or 2 MB L2 cache. The L2 cache was implemented with custom 512 kB SRAMs developed by Intel. The number of SRAMs depended on the amount of cache. A 512 kB configuration required one SRAM, a 1 MB configuration: two SRAMs, and a 2 MB configuration: four SRAMs on both sides of the PCB. Each SRAM was a 12.90 mm by 17.23 mm (222.21 mm²) die fabricated in a 0.35 µm four-layer metal CMOS process and packaged in a cavity-down wire-bonded land grid array (LGA). The additional cache required a larger module and thus the Pentium II Xeon used a larger slot, Slot 2. It was supported by the 440GX dual-processor workstation chipset and the 450NX quad- or octo-processor chipset.

Gulftown

Gulftown or Westmere-EP is the codename of an up to six-core hyperthreaded Intel processor able to run up to 12 threads in parallel. It is based on Westmere microarchitecture, the 32 nm shrink of Nehalem. Originally rumored to be called the Intel Core i9, it is sold as an Intel Core i7. The first release was the Core i7 980X in the first quarter of 2010, along with its server counterpart, the Xeon 3600 and the dual-socket Xeon 5600 (Westmere-EP) series using identical chips.

First figures indicate that at equivalent clock rates, depending on the software, it has up to 50% higher performance than the identically clocked quad-core Bloomfield Core i7-975. However, consumer software that utilizes six real cores is still quite rare as of 2011, and not every multithreaded program is able to take advantage of this many cores. Despite having 50% more transistors, the CPU strongly benefits from the 32-nm process, drawing the same or even less power (depending on the operating system) than its Bloomfield predecessors with merely four cores. The thermal design power (TDP) of all planned models is stated to be 130 watts.

Dual

Dual may refer to:

Dual! Parallel Trouble Adventure

Dual! Parallel Trouble Adventure (デュアル!ぱられルンルン物語, Dyuaru! Parare Runrun Monogatari) is a fourteen episode series created in 1999 by Masaki Kajishima and produced by AIC, both well known for the Tenchi Muyo! franchise. It is licensed in the US by Pioneer LDC, later known as Geneon. In addition to the original run, an OVA special was added to conclude the series as a de facto "14th episode".

Title explanation

The title refers to the fact that the story takes place in two parallel universes, a concept loosely based on multiverse theory.

Plot

22 years ago, a huge alien artifact is found on a construction site by a worker named Yotsuga. The foreman orders that the artifact be broken apart to avoid delays. As Yotsuga walks towards the dumpsters to dispose of a small piece of the artifact, the world splits into two. In one world, Yotsuga tosses away the piece and the artifact is destroyed. In the other world, Yotsuga keeps the artifact, leading to the discovery of extraterrestrial technology that changes history.

Dual (film)

Dual is a 2008 independent Western drama film. It was directed by Steven R. Monroe and written by and starring Michael Worth.

Plot

Luke Twain is a drifter who finds a small settlement where everyone has been killed. Trying to do the right thing and solve the gruesome mystery, he finds himself taking a journey into fear and death.
