Intel Core i5-661: specs and benchmarks
Intel started Intel Core i5-661 sales 7 January 2010 at a recommended price of $252. This is Clarkdale architecture desktop processor primarily aimed at office systems. It has 2 cores and 4 threads, and is based on 32 nm manufacturing technology, with a maximum frequency of 3600 MHz and a locked multiplier.
Compatibility-wise, this is FCLGA1156 processor with a TDP of 87 Watt. It supports DDR3-1066, DDR3-1333 memory.
It provides poor benchmark performance at 2.75 percent of a leader's which is AMD EPYC 7763.
Of Core i5-661 processor market type (desktop or notebook), architecture, sales start time and pricing.
Basic microprocessor parameters such as number of cores, number of threads, base frequency and turbo boost clock, lithography, cache size and multiplier lock state. These parameters can generally indicate CPU performance, but to be more precise you have to review its test results.
Information on Core i5-661 compatibility with other computer components and devices: motherboard (look for socket type), power supply unit (look for power consumption) etc. Useful when planning a future computer configuration or upgrading an existing one. Note that power consumption of some processors can well exceed their nominal TDP, even without overclocking. Some can even double their declared thermals given that the motherboard allows to tune the CPU power parameters.
