Core i7-920 Specifications

As you probably know by now the Intel Core series of processors is not just a rehash of its previous Core 2 Duo technology. Instead it uses a completely unique design that embraces much of the new Nehalem technology fully described in "First the Tick, Now the Tock: Next Generation IntelMicroarchitecture (Nehalem)". Intel has gone to great lengths to avoid having their newest product entitled "just another revision" by their consumer market. They have shown their confidence in the Intel Core series by making this product launch the biggest and arguably the best in their history, even in a time where the economy is less than prosperous.

Processor Architecture New Intel Core Microarchitecture (Nehalem) 45nm

With the Core i7 series Intel has produced their first true, native quad-core processor which incorporates multiple cores on a single processor die. This is unlike the existing Core 2 Quads which feature two dual core processor dies mounted on a single piece of silicon. The Core i7 processors also eliminate the need for the Northbridge chipset to manage system memory and link it to the processor with integrated, on die memory controller which links the processor directly to the system memory. You might be asking yourself: Isn't this design is eerily similar to the AMD Phenom? From this limited point of reference you would be right.

Intel Core i7 Features

Another very interesting feature is Intel's QuickPath Interface. QuickPath Architecture is a platform architecture that provides high-speed connections between microprocessors and external memory, and between microprocessors and the I/O hub. One of its biggest changes is the implementation of scalable shared memory. Instead of using a single shared pool of memory connected to all the processors in a server or high-end workstation through FSBs and memory controller hubs, each processor has its own dedicated memory that it accesses directly through an Integrated Memory Controller on the processor die. In cases where a processor needs to access the dedicated memory of another processor, it can do so through a high-speed Intel QuickPath Interconnect that links all the processors. An advantage of Intel QuickPath Interconnect is that it is point-to-point. There is no single bus that all the processors must use and contend with each other to reach memory and I/O. This improves scalability and eliminates the competition between processors for bus bandwidth.

Features & Benefits
Feature Benefit
Quad Core Processing Provides four independent execution cores in one processor package. Four dedicated processing cores help operating systems and applications deliver additional performance, so end users can experience better multitasking and multithreaded performance across many types of applications and workloads.
IntelHyper-Threading Technology Delivers two processing threads per physical core for a total of eight threads for massive computational throughput. With IntelHyper-Threading Technology, highly threaded applications can get more work done in parallel, completing tasks sooner. With more threads available to the operating system, multitasking becomes even easier. This amazing processor can handle multiple applications working simultaneously, allowing you to do more with less wait time.
IntelTurbo Boost Technology Dynamically increases the processor's frequency as needed by taking advantage of thermal and power head-room when operating below specified limits. Get more performance automatically, when you need it the most.
8 MB IntelSmart Cache Dynamically increases the processor's frequency as needed by taking advantage of thermal and power head-room when operating below specified limits. Get more performance automatically, when you need it the most.
IntelQuickPath Interconnect Intel's latest system interconnect design increases bandwidth and lowers latency, while achieving data transfer speeds as high as 25.6 GB/s.
Integrated Memory Controller An integrated memory controller with three channels of DDR3 1066 MHz offers memory performance up to 25.6 GB/s. Combined with the processor's efficient prefetching algorithms, this memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.
IntelHD Boost Includes the full SSE4 instruction set, significantly improving a broad range of multimedia and compute-intensive applications. The 128-bit SSE instructions are issued at a throughput rate of one per clock cycle allowing a new level of processing efficiency with SSE4-optimized applications.
Digital Thermal Sensor (DTS) Provides for more efficient processor and platform thermal control improving system acoustics. The DTS continuously measures the temperature at each processing core. The ability to continuously measure and detect variations in processor temperature enables system fans to spin only as fast as needed to cool the system. The combination of these technologies can result in significantly lower noise emissions from the PC.
IntelWide Dynamic Execution Improves execution speed and efficiency, delivering more instructions per clock cycle. Each core can complete up to four full instructions simultaneously.
IntelSmart Memory Access Improves system performance by optimizing the use of the available data bandwidth from the memory subsystem and reducing the effective latency of memory accesses.

I checked on prices the i7-920 is almost the same price as the i7-950. Why? It is hard to find the 920. I assume that the 950 is better then the 920.

The free market sometimes behave s with random stupidity, and this situation is quite common, especially for CPUs. They are no longer producing the "920", so there is limited supply, but the "950" is a direct replacement, so what does it matter?
