so Add to compare
The general trademark of a manufacturer by which the consumer knows its products. A manufacturer can have multiple brand names. Some manufacturers license their brand names to other producers.
Product name:
Product name is a brand's identification of a product, often a model name, but not totally unique as it can include some product variants. Product name is a key part of the Icecat product title on a product data-sheet.
Intel® Core™2 Extreme Processor QX6700 (8M Cache, 2.66 GHz, 1066 MHz FSB)
Product code :
The brand's unique identifier for a product. Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. We map away wrong codes or sometimes logistic variants.
The Central Processing Unit (CPU) or (micro) processor is the part of a computer where most calculations take place. In terms of computing power, the processor is the most important element of a computer system, so the performance of a computer is highly dependant on the performance of the processor. For quite some time the performance of a processor has been determined by the number of MHz the clock speed was, but nowadays clock speed doesn\'t have so much to do with the speed of the processor anymore. One of the best ways to compare different kinds of processors, is to look up benchmarks on the internet. Please be careful to buy a processor that is compatible with your motherboard, i.e. fits in the right socket.
Data-sheet quality: created/standardized by Icecat

Processor family *
A family of processors is a group of processors produced by one company over a short period of time e.g. Intel Pentium processors.
Intel Core 2 Extreme
Processor frequency *
The speed that the microprocessor executes each instruction or each vibration of the clock. The CPU requires a fixed number of clock ticks, or cycles, to execute each instruction. The faster the clocks rate, the faster the CPU, or the faster it can execute instructions. Clock Speeds are usually determined in MHz, 1 MHz representing 1 million cycles per second, or in GHz, 1 GHz representing 1 thousand million cycles per second. The higher the CPU speed, the better a computer will perform.
2.66 GHz
Processor cores *
The number of central processing units ('cores') in a processor. Some processors have 1 core, others have 2 (e.g. Intel Core Duo) or more (e.g. the Intel Xeon E7-2850 has 10 cores).
Processor socket *
Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering.
LGA 775 (Socket T)
Processor lithography *
The process which is performed by the processor e.g. CPU (Central Processing Unit).
65 nm
Box *
Plastic or metal shell/container for components.
Processor model *
The model number for the processor in a computer.
Processor threads *
Processor operating modes *
Operating modes for the processors that place restrictions on the type and scope of operations for certain processes run by the CPU. This design allows the operating system to run with more privileges than application software.
Processor front side bus
A computer communications interface used to connect the processor to the rest of the computer, except the cache (and possibly other processors).

Andrew B9.5Intel are once again the current market leaders in processor designs and with the introduction of the dual-core Conroe processors, Intel have raced past AMD in terms of power and performance. However as the processor market never remains st...
The QX6700 is scheduled to replace the X6800 as Intels flagship desktop CPU. As the X6800 should disappear pretty quickly, its pretty pointless comparing the two. While the QX6700s four cores mean that its much faster than any other chip in multith...
Bottom line The QX6700 is scheduled to replace the X6800 as Intels flagship desktop CPU. As the X6800 should disappear pretty quickly, its pretty pointless comparing the two. While the QX6700s four cores mean that its much faster than any other chip in multith...

Intels Core 2 range of processors impressed us. The E6700 won our Best Component award in Shopper December 2006. Never a company to rest on its laurels, Intel has released the Core 2 Extreme QX6700 processor, which has four processor cores. From th...
The QX6700 is based on the same 65nm manufacturing process as the other Core 2 processors. It incorporates a total of 8MB of L2 cache, as 4MB per pair of cores. Therein lies a problem: the two caches arent interconnected. So each pair of cores share...
Bottom line The Intel Core 2 Extreme QX6700 offers a glimpse of what the future holds, but for now there are few apps crying out for a quad-core processor. Windows Vista may bring better support for multi-threading, ensuring each thread has the same access to CPU...
If you thought dual-core processors were cutting edge, youre already behind the times. Quad core is here, in the form of the Extreme QX6700. The processor itself isnt a "native" quad-core part. By this, we mean the four execution cores dont exist...

Performance per watt has taken a backward step, but it?s very fast with the right apps.
Are we here already? It was just on four months ago that we looked at Core 2 Duo, and we were blown away. Now suddenly we already have two more cores for the taking.Sure, it’s just two Duos whacked on the one silicon slab, thus not using a shared ca...
Needless to say, the gigahertz war between AMD and Intel is history. Comparing clock speeds does not do justice to CPU performance today - unless youre comparing processors within a product family. For the time being, performance is tied to the numb...
