Con il comunicato stampa di seguito allegato, Intel ha annunciato ufficialmente i nuovi processori per desktop ad alte prestazioni della nuova linea Core i5 e due nuovi Core i7 e la gamma di cpu per server Xeon. Più in dettaglio vanno ad ampliare il catalogo di Intel i seguenti chip: Core i5-750, Core i7-870, Core i7-860, Xeon X3470, Xeon X3460, Xeon X3450, Xeon X3440, Xeon X3430 e Xeon L3426. Le specifiche ufficiali sono incluse nella tabella che segue.

Si tratta di processori basati sull'architettura Nehalem, dotati di supporto delle tecnologie proprietarie Intel Turbo Boost Technology e Intel Hyper-Threading Technology (quest'ultima è disponibile in tutti i Core i7 e negli Xeon, ad eccezione della variante Xeon X3430). I nuovi processori hanno un TDP dichiarato pari a 95W, che scende fino a 45W nel caso della implementazione low-power siglata Xeon L3426.

I nuovi Core i5 e i7, spesso indicati con il nome in codice di "Lynnfield" e compatibili con il socket LGA-1156, sono i primi processori di Intel a integrare un memory controller dual-channel e una porta per la gestione dei flussi video mediante PCI Express a 16 linee.

Il chip maker statunitense ha anche annunciato il chipset Intel P55 Express, destinato a gestire le nuove cpu per desktop e in grado di supportare 8 porte PCI-Express 2.0 x1 e le sezioni video dual-gpu con una configurazione 2x8 in termini di PCI-E. Inoltre, Intel P55 Express supporta sei porte SATA II a 3Gb/s, con l'ausilio della tecnologia proprietaria Intel Matrix Storage technology, che permette la gestione delle device di storage in RAID 0/1/5/10, e fino a 14 porte USB.

SANTA CLARA, Calif., Sept. 8, 2009 – Intel Corporation introduced several high-performance desktop and server processors today, bringing the next level of integration and intelligence to computers. The new Intel Core i5 processor family, two new Intel Core i7 processors and the Intel Xeon processor 3400 series bring Intel's latest Nehalem microarchitecture to mainstream desktop and entry server markets.

New Intel Core Processors for Consumers
Formerly codenamed "Lynnfield," these new chips are based on Intel's award-winning Nehalem microarchitecture and are designed for consumers who need top-notch performance for digital media, productivity, gaming and other demanding applications. These processors, along with the new Intel P55 express chipset, are available today.

All processors are lead- and halogen-free¹ and feature Intel exclusive Turbo Boost Technology. The top-of-the-line Core i7 processors also support Intel Hyper-Threading Technology. Combined, these features give computer users absolute "intelligent" performance when necessary and optimum power-efficiency when the computer is lightly loaded.

Computers Just Got Smaller
The new chipset brings the most revolutionary design changes since the invention of the PCI bus in the early 1990s and sets the stage for Intel's forthcoming 2010 compute platform. The Intel P55 Express Chipset will be the baseline building block component for motherboards worldwide, delivering great new levels of performance and scalability for everyone from the retail buyer to the technically savvy do-it-yourselfer.

The new Core i7 and i5 processors are the first Intel processors to integrate both a 16-lane PCI Express 2 graphics port and two-channel memory controller, enabling all input/output and manageability functions to be handled by the single-chip Intel P55 Express Chipset. Previous Intel chipsets required two separate chips. A new Direct Media Interface (DMI) connects between the processor and chipset. The chipset supports 8 PCI Express 2.0 x1 Ports (2.5GT/s) for flexible device support. Dual graphics cards are supported in a "2x8" configuration. The chipset also supports 6 SATA 3 Gb/s Ports with Intel Matrix Storage Technology providing RAID levels 0/1/5/10. Up to 14 USB 2.0 Ports can be supported with the chipset's integrated USB 2.0 Rate Matching Hub, along with Intel High Definition Audio for premium digital sound. The new processors are the first to be supported by the new Land Grid Array (LGA) 1156 package and socket technology.

Better Entry Servers
Small businesses requiring 24/7 operation and educators now have more reasons than ever to buy a purpose-built server with Intel's new Xeon processors and Intel 3400 and 3420 chipsets. These new products improve small business productivity by running email, file, print and dynamic Web serving tasks more efficiently. They also improve education by enabling dependable classroom collaboration and making school administrative services more productive. Servers based on Xeon 3400 processors provide more dependability over desktop systems through differentiated features such as Error Correcting Code memory and RAID 0/1/5/10 for server operating systems. They are designed to help small businesses grow by enabling up to 64 percent² more sale transactions and up to 56 percent faster business response time. This improvement is enabled with Intel's Nehalem microarchitecture and a 4x improvement in memory capacity (32 GB). Intel Turbo Boost Technology and Intel Hyper-Threading Technology enable these servers to automatically adapt their performance to unique business needs. The processors launched today also include the Intel Xeon L3426, a low-power variant that delivers up to 188 percent improvement in energy efficiency per dollar than the previous-generation Intel Xeon X3380, and enables innovative server form factors for space and thermally constrained environments.
