[closed] what are the differences between i3 i5 and i7?

i3 = Slowest i5 = Middle i7 = fastest

The Core i3 was intended to be the new low end of the performance processor line from Intel, following the retirement of the Core 2 brand.[17][18]

The first Core i3 processors were launched on January 7, 2010.[19]

The first Nehalem based Core i3 was Clarkdale-based, with an integrated GPU and two cores.[20] The same processor is also available as Core i5 and Pentium, with slightly different configurations.

The Core i3-3xxM processors are based on Arrandale, the mobile version of the Clarkdale desktop processor. They are similar to the Core i5-4xx series but running at lower clock speeds and without Turbo Boost.[21]

Core i5,[22] like Core i7, is based on the Nehalem microarchitecture. The first Core i5 was introduced on September 8, 2009 and is a mainstream variant of the Core i7, initially only quad-core desktop processors based on Lynnfield, with dual-core mobile (Arrandale) and desktop processors (Clarkdale) following in 2010.

As of 2010, Core i7 is the high end of the Core brand,[23] which was introduced with the Bloomfield Quad-core processor in late 2008. In 2009, new Core i7 models based on the Lynnfield desktop quad-core processor and the Clarksfield quad-core mobile were added, and models based on the Arrandale dual-core mobile processor have been announced. The first six-core processor in the Core lineup is the Gulftown, which was launched on March 16, 2010. Both the regular Core i7 and the Extreme Edition are advertised as five stars in the Intel Processor Rating.

I have an i7 860 2.8ghz and this thing runs like a beast.

That chart that recck posted cannot be correct. I'm on an iMac with an Intel Core 2 Duo and I can edit HD video very well. I can also make home videos just fine. I can play social online games, I've been designing my own website in Dreamweaver for a long time now, and I can run applications like Photoshop just fine.

That chart isn't that good in my opinion. I'm upgrading to an Intel Core i3 iMac next month and it annoys me that Intel says that it's not a good chip for the tasks I mentioned above. If my Intel Core 2 Duo can do those tasks great, can't an Intel Core i3 do it better? Isn't the i3 a better chip?
