Core i5 based on Core i7 Nehalem architecture,code-named Lynnfield.It has most Core i7 technological characteristics,such as integrated memory controller,support for dual-channel DDR3 memory, L3 cache systems, supporting smart acceleration technology Turbo Mode. as well as to accelerate the Hyper-Threading Technology. Core i5, using native quad-core design,upto 8 thread after opening the Hyper-Threading technology. Core i5 also has 8MB of L3 cache.
Mainstream Core i5 and high-end Core i7 have the biggest difference in interface. The latter adopts LGA 1366 interface, while Core i5 will be LGA 1156 interface, which means they can only be used on corresponding motherboards without compatibility. In addition, Core i5 does not use QPI bus, replaced by mature DMI (DirectMediaInterface) bus. Corresponding chipset is a P55/P57 for Core i5. Core i5 will be released in the third or fourth quarter, 2.13G Core i5 multi-thread performance is close to 3G Core 2 Quad.
More information about entry-level Core i3 :
Core i3 adopts 32nm technology (codenamed Clarkdale, based on Westmere architecture). Its biggest characteristics is integrated GPU, that is to say, Core i3 will be in CPU + GPU package from. Due to the limited performance of integrated GPU, users can add graphics outside for better 3D performance. Despite of Clarkdale, graphics kernel process is still 45nm.
Core i3 CPU adopts dual-core design in specs.It can support 4 threads, L3 cache is reduced from 8MB to 4MB. memory controller, dual-channel, intelligent acceleration technology, hyper-thread technology will be retained. Corresponding motherboard will be P55/P57. Core i3 processors will be published next year.

If im not mistake, what u posted about the i5 is correct
the i3 ive never even heard of till just now but ill look at more sources
In the OP's message, it stated a 2.13GHz i5 == Q9650 in multithreaded apps. I believe the informations that was stated is mistaken as my i7 920 at stock speeds is only marginally faster than the Q9650 in some apps. In some apps, of course, the i7 920 dominates it, but not the point where 2.13GHz i5==Q9650.
I'm going to assume that i3 corresponds to the 32nm Clarkdale with onboard GPU and reduced cache levels.
This news has been around forever, and Intel has stated that i5 will not be the marketing name for Lynnfield, so I doubt i3 will be the name for Clarkdale.
Even i5 is not a confirmed name by Intel hence I still use LGA1156 when referring to i5.

i3 is the scaled down Nehalem. It has the 32nm CPU and 45nm GPU on the same die using Socket H(715). Supposedly, the lower pin count is because it has no IMC (It will use DDR2 IIRC).
It will probably be marketed as a Nehalem version of a Celeron, so it will probably only be good for ultra-lowend desktops. Might be good in bargain laptops, though.
I've seen no credible source which would indicate there will ever be any Nehalem or Westmere-generation CPUs released without an IMC, and lots of evidence to the contrary.

Ultra-lowend? Its still based off of the Nehalem architecture, how lowend can it be?
