Handling Threads in quad core processor

This depends on the exact processor line and model.

Intel's Core i7, i5, and i3 series can handle 2 threads per core, so any quad-core model could handle 8 threads.

AMD's Athon, Phenom, Sempron, and Opteron chips, on the other hand, are designed around a 1-thread-per-core model.

At the other extreme end, are the SPARC Niagara series of server chips, which can handled anywhere from 8 to 16 threads per core.


All this isn't free. Thread count per core comes at a cost - the more threads per core, the lower performance each individual thread has. That is, using the same hardware, if I run one thread on a core, that thread will run faster than 2 similar threads, even if the threads are independent.

Intel QuickPath Interconnect is designed for increased bandwidth and low latency. It can achieve data transfer speeds as high as 25.6 GB/sec with the Extreme Edition processor.

Integrated memory controller enables three channels of DDR3 1066 MHz memory, resulting in up to 25.6 GB/sec memory bandwidth. This memory controller's lower latency and higher memory bandwidth delivers amazing performance for data-intensive applications.

Intel HD Boost significantly improves 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.

AES-NI Encryption/Decryption Acceleration provides 6 new processor instructions that help to improve performance for AES encryption and decryption algorithms.

Core i5 Processor

Native quad-core structure. Single processor die contains four cores with 256 KB L2 cache each and shared L3 cache; Elimination of the processor bus in its traditional form due to relocation of the PCI Express 2.0 controller directly into the CPU. This controller integrated into the processor provides support for 16 PCI Express 2.0 lanes, which can be used for one (in PCI Express x16 mode) or two (in PCI Express x8 mode) graphics cards.
Memory controller integrated into the CPU that supports dual-channel DDR3 SDRAM. Each memory channel can work with three unbuffered memory DIMMs. 8MB shared L3 cache. Integrated PCU microcontroller that independently controls the voltage and frequency of each core and can automatically overclock individual cores in case the remaining ones are not fully utilized. New SSE4.2 instructions support. Core i7-800 and Core i5-700 are manufactured with 45 nm process and consist of 774 million transistors on a 296 mm2 die.
