Intel Core i5-661 Processor BX80616I5661

Benchmark Reviews
28 January 2010
  • Conclusion: Even at its arguably inflated price, the Core i5-661 represents the sweet spot in the Clarkdale Core i5 lineup. The Core i5-670 adds fractionally more speed (3.46GHz vs 3.33GHz) and Trusted Execution Technology, but drops iGPU speed from 900MHz to 733MHz..
  • Pros: Good performance, Turbo Boost technology, Hyper-Threading technology, Integrated GPU provides excellent Windows Aero and HD content performance, 32nm process gives great overclocking headroom, Low power draw (when not overclocked)
  • Cons: Overpriced for the level of performance provided, Integrated GPU inadequate for even low-end gaming, Requires new motherboard to use integrated GPU, Very high power draw when overclocked, iGPU requires 32M-128M of memory for a frame buffer, Relationship between BCLK and iGPU clock unclear

Intel Core i5 661 3.33 GHz

19 January 2010
  • Summary: Just like at the beginning of review I'll try to start off with good aspects of Clarkdale, or Core i5 661. First of all, innovative integration of the 45nm Northbridge with two 32 nm processor cores in one die is a huge step forward.
  • Pros: "Northbridge" module integration, New 32 nm process node, Low power consumption and heat output, Exceptional performance for a Dual Core processor, Overclocking potential
  • Cons: High Price, Memory and PCI-E controller not in processor core, No IGP control on P55 boards, Half of the Clarkdale chip is pure waste for gamers

  • Excerpt: The Core i5-661 can't match the similarly priced, quad-core Core i7-750 in speed, but its integrated graphics and simpler chipset make it a good base for inexpensive PCs with better performance than earlier dual-core chips.
  • Pros: Excellent speed for a dual-core CPU, Decent integrated graphics built-in, Inexpensive
  • Cons: Requires newest motherboard chipset for graphics support, Confusing model designation

  • Summary: Really low power, decent performance. Integrated GPU seems to affect overclocking initially, as expected.

Intel Core i5 661

21 December 2010
  • Conclusion: Proces integrowania w procesorze coraz większej ilości komponentów trwa od kilku lat. Zapoczątkowało go AMD w 1999 przenosząc do procesora kontroler pamięci. Zabieg okazał się trafieniem w dziesiątkę, przez pewien czas procesory AMD pod względem wydajności królowały nam układami konkurencji.
  • Pros: Dobra wydajność, Niezła wydajność zintegrowanego układu graficznego
  • Cons: Drogi
