All Clarkdale based processors so far, carry TDP rating of 73W. Clocked at 2.80 GHz, its feature-set is nearly identical to that of the Core i3, except for that it has 3 MB of available 元 cache, and HyperThreading is excluded from the feature-set. Each core has a dedicated L2 cache of 256 KB, while a 4 MB 元 cache is shared between two cores.įinally, Intel's first sub-$100 Pentium dual-core offering based on this architecture will be called Pentium G6950. All these processors feature two cores, and HyperThreading technology enabling four logical CPUs (threads). Price-wise, Core i3 dual-core processors tentatively range between US $123~$143, while Core i5 dual-core ones between $176~$284.
Core i5 670 -3.43 GHz, with Turbo Boost speed of 3.73 GHzĬore i5 models have their model number series beginning in the 600 series, and take off where the 500 series Core i3 processors leave (next to Core i3 5 30, is Core i5 6 40).
Core i5 660 -3.33 GHz, with Turbo Boost speed of 3.60 GHz.
Core i5 650 -3.20 GHz, with Turbo Boost speed of 3.43 GHz.
For example, a core i5 chip rated at a hefty 2.5 GHz can kick up to 3 GHz on demand without stressing the processor or running the risk of overheating. It automatically speeds up the processor for a burst of heavy-duty activity when your PC needs extra performance. This is one of the many exciting new features the Intel chip has built into core i5 and core i7 processors. You may come across Intel’s Turbo Boost Technology while shopping for a new PC. Remember: Don’t compare computers based on clock speed unless they use the same line of processors – such as Intel core i3, i5 or i7. Hence your new i5 or i7 running at 3.0 GHz plus cannot be compared to any older generation Pentium 4 hardware. The i series 1.6 GHz CPU runs faster and outperforms the old style Pentium 4 CPU. Once, a higher number meant a faster processor, but advances in technology have made the processor chip more efficient so now they do more with less.įor example: An Intel Core i5 running at 3.46 GHz is not faster than an Intel Core i7 running at 3.06 GHz.Ĭomparing the speed of your old Pentium 4 CPU (an old scale which peaked at 3.4 GHz) with the speed of the current i series CPU’s (the new scale which started at 1.6 GHz) is a bit like comparing the Fahrenheit with Celsius temperature scales. Clock speed is the rate at which a processor executes a task and is measured in Gigahertz (GHz).
