Intel introducerer Pentium 4 E

Intel har i dag introduceret deres første processorer baseret på 90nm teknologi, under navnet Pentium 4 E, med clockfrekvenser på 2.8, 3.0, 3.2 og 3.4 GHz. Samtidig har de introduceret 3.4 GHz versioner af Pentium 4 C og Pentium 4 XE/EE (Extreme Edition), som begge benytter den gamle 130 nm teknologi.

Den nye Pentium 4 E benytter som sagt Intels nye 90nm teknologi, og har 1 MB L2 cache. Arkitekturen er ændret i forhold til forgængeren, den såkaldte pipeline er ændret, så den nu har 31 trin, hvor Pentium 4 C har 20 trin. Samtidig har Intel indført et nyt instruktionssæt, som supplement til de eksisterende udvidelser af x86 teknologien, SSE3 skal være med til at øge hastigheden i visse applikationer. Den længere pipeline, skal gøre det muligt at hæve clockfrekvensen til op imod 5 GHz.

De mange tests på nettet, viser alle det samme billede: Den nye Pentium 4 E kan ikke hamle op med den gamle ! Der er dog ingen tvivl om at det billede vil ændre sig, i takt med at højere clockfrekvenser vil blive indført. Du kan læse pressemeddelelsen nedenunder de følgende links.

Her følger en oversigt over mange af de tests du kan finde på nettet:

Intel Introduces Intel® Pentium® 4 Processors On High-Volume 90-Nanometer Manufacturing Technology
SANTA CLARA, Calif., Feb. 2, 2004 - Intel Corporation is delivering four new processors (formerly codenamed Prescott) that are built on the company's industry-leading, high-volume 90-nanometer (nm) manufacturing technology. These processors are among six new offerings in Intel's line of desktop chips, bringing new features and high performance to a wide range of PC users, from mainstream consumers and businesspeople to gaming enthusiasts and computer power users.

"This new manufacturing technology, along with numerous architectural enhancements, enable us to continue delivering products that allow end users to interact with a wide variety of digital devices," said Bill Siu, vice president and general manager, Intel Desktop Platforms Group. "These processors provide improved responsiveness for today's corporate and home applications, and offer headroom for the next wave of technologies."

Intel's 90 nm (a nanometer is one-billionth of a meter) process technology is the most advanced semiconductor manufacturing process in the industry, built exclusively on 300 mm wafers. This new process combines high performance, low-power transistors, strained silicon, high-speed copper interconnects and a new low-k dielectric material. This is the first time all of these technologies have been integrated into a single manufacturing process.

Intel® Pentium® 4 processors built on the 90-nm process retain the multitasking capabilities of Hyper-Threading (HT) Technology, and include new features such as enhanced Intel® NetBurst? microarchitecture, a larger, 1 MB Level 2 (L2) cache and 13 new instructions.

Desktop Processor Family Fuels Office and Digital Home Usage Models
Intel's family of Intel Pentium 4 processors supporting HT Technology provide home and business users a great computing experience by keeping the PC responsive while processing other tasks in the background. For example, a home user can play an immersive game while encoding audio or video, compressing images or compositing special effects. An IT department can run background applications such as continuous virus scanning, encryption or compression simultaneously, while minimizing disruption for other business users in the same computing environment.

In addition to the four processors manufactured on the 90-nm process, Intel added a 3.40 GHz version of the Intel Pentium 4 processor supporting HT Technology based on Intel's 0.13-micron process technology to its desktop processor family.

Updated, Extreme Performance for Gaming
Intel has also revved up the speed of its Pentium® 4 processor Extreme Edition supporting HT Technology to 3.40 GHz. This processor is built on Intel's 0.13-micron process technology, and is targeted specifically for high-end gamers and computer power users with its 2MB of on-die Level 3 (L3) cache. These users can now expect an even better experience when pushing their PCs to the edge of performance.

The Intel Pentium 4 processor with HT Technology Extreme Edition at 3.40 GHz delivers the highest Microsoft Windows XP* desktop processor performance as measured by SPEC CPU 2000 (compared to other Microsoft Windows desktop processor results published at http://www.specbench.org/cpu2000/results/ as of Feb. 1) with a SPECint*_base2000 score of 1666 and a SPECfp*_base2000 score of 1546.

Specifications, Pricing and Availability
Intel is shipping boxed versions of these processors to Intel authorized distributors for system integrators worldwide. Availability of OEM systems based on Intel Pentium 4 processors with HT Technology at 3.40 GHz and built on 90-nm process technology is expected later in the first quarter of 2004.
