Intel Core i5 Processor i5-661 3.33GHz 4MB LGA1156 CPU BX80616I5661
The Intel Core i5-661 Processor brings great performance, Intel HD Graphics built-in, , and the latest Intel technologies to your desktop computer. With two cores running at 3.33 GHz, the Core i5-661 won't have any problems handling your everyday applications. And when you need an extra burst of speed, the processor can utilize Intel Turbo Boost Technology to run at up to 3.6 GHz.Intel Core i5-661features:Two 3.33 GHz cores for better multitasking and multithreaded performance.Turbo Boost Technology boosts core to 3.6 GHz when needed.Integrated Intel HD Graphics with a 900 MHz graphics core.4 MB of Intel Smart Cache.The Intel Core i5-661 processor delivers outstanding performance at a great price.View larger.Multiple Cores for Speedy, Multi-Threaded PerformanceThe Intel Core i5-661 contains two processors, or execution cores, on one integrated circuit. Combined with four threads, the Core i5-661 can simultaneously work on multiple tasks. This design produces faster and more efficient results, so your computer won't slow down--no matter how many applications you have open.Turbo Boost Technology Gives Extra Speed When You Need ItIntel Turbo Boost Technology automatically oversees your workload, redirecting power and moderating performance for better efficiency. In the past, unused portions of a chip would be turned off, leaving some cores idle. But with Turbo Boost Technology, unused performance is now routed to active cores, boosting performance without wasting power. With Turbo Boost enabled, the Intel Core i5-661 Processor accelerates from its usual 3.33 GHz up to a maximum single-core frequency of 3.6 GHz.Hyper-Threading for Better EfficiencyThe Intel Core i5-661 Processor features Intel Hyper-Threading Technology to deliver more efficient use of resources and better performance on multithreaded software. You'll be able to run demanding desktop applications, such as music and movie creation applications, while running background applications, such as virus protection software, and still maintain system responsiveness.Large Smart Cache for Better Media PerformanceIntel Smart Cache provides performance-maximized storage for frequently accessed data. The Intel Core i5-661 has a generous 4 MB of Intel Smart Cache kept close to the processor, so there's always data feeding in. The result is better overall functionality for everyday applications and markedly improved performance for rich media titles and games.Intel HD Graphics Built-inWith the Core i5-661, Intel HD Graphics is built right into the CPU, so you won't have to spend money on a discrete graphics card in order to get stunning results. Intel HD Graphics provides sharp images, rich color, and lifelike audio and video. Intel HD Graphics support multiple monitors, premium video such as Blu-ray Disc playback and mainstream gaming as well as a full Windows 7 experience. The Core i5-661 has a graphics core that runs at 900 MHz to maximize viewing power.The Intel Core i5-661 is made on a 32nm manufacturing process for better energy efficiency. It uses the LGA1156 socket.Intel Core i5-600 Processor SeriesCore i5-680 ProcessorCore i5-670 ProcessorCore i5-661 ProcessorCore i5-660 ProcessorCore i5-650 ProcessorCores / Threads2 Cores / 4 Threads2 Cores / 4 Threads2 Cores / 4 Threads2 Cores / 4 Threads2 Cores / 4 ThreadsProcessor Frequency3.60 GHz / 3.86 GHz with turbo boost3.46 GHz / 3.73 GHz with turbo boost3.33 GHz / 3.60 GHz with turbo boost3.33 GHz / 3.60 GHz with turbo boost3.20 GHz / 3.46 GHz with turbo boostIntel Smart Cache4 MB4 MB4 MB4 MB4 MBSilicon32 nm32 nm32 nm32 nm32 nmIntegrated HD GraphicsYesYesYesYesYesGraphics Base Frequency733 MHz733 MHz900 MHz733 MHz733 MHzNumber of Memory Channels2 (DDR3 1333 MHz)2 (DDR3 1333 MHz)2 (DDR3 1333 MHz)2 (DDR3 1333 MHz)2 (DDR3 1333 MHz)Intel Trusted Execution TechnologyYesYesNoYesYesSocketLGA1156LGA1156LGA1156LGA1156LGA1156
