Intel 32nm Core i3, Core i5 processors now listed

Update: Clarkdale shows up in German etail store


Intel has yet
to release the world’s first 32nm commercial microprocessors within the IT consumer market in two months, and we are already beginning to see the first product listings emerge on the European etail market.

A few hours ago, Germany-based website HPM-Computer recently posted several listings of upcoming 32nm dual-core desktop LGA 1156 processors codenamed Clarkdale, also known as the Core i3 5xx-series and Core i5 6xx-series respectively. These are also the first chips to integrate a 45nm IGP core and memory controller alongside the 32nm Westmere-based CPU, all within a single die package. Unfortunately, Intel asked the site to remove its postings, but we were able to capture the specifications and sort them into a launch chart.

In January 2010, Intel plans to launch the Core i3-530 2.93GHz (733MHz Intel graphics), Core i3-540 3.06GHz (733MHz Intel graphics ), Core i5-650 3.20GHz (733MHz Intel graphics ), Core i5-660 3.33GHz (733MHz Intel graphics ), the faster Core i5-661 3.33GHz (900MHz Intel graphics), and the Core i5-670 3.46GHz (733MHz Intel graphics).

A larger graph can be found here.

When January arrives, all of the 32nm Clarkdale-based Core i3 and Core i5 models will be available for pre-order and on sale shortly thereafter. The Core i3 models do not feature Simultaneous multithreading (SMT, formerly HyperThreading) and thus will only display two logical cores in Task Manager. On the other hand, all Core i5-5xx series and Core i5-6xx series models feature SMT support and will display four logical cores in Task Manager, meaning two cores with four threads.

It is also important to note that thermal design power (TDP) increases linearly as the integrated graphics core is rated at higher frequencies. Intel has decided to single out its Core i5 661 3.33GHz as the model with a 900MHz Intel graphics core frequency that will provide the most sufficient 3D performance. Perhaps the engineers did not push the IGP to this speed on the Core i5 670 simply because 3.46GHz is fairly high for dual CPU cores and going any further on the 45nm GPU core might have affected overall chip stability.

We will be keeping our eyes peeled for any future Clarkdale-based Core i3 and Core i5 desktop chip sightings as well as their Arrandale-based mobile Core i3-M, Core i5-M and Core i7-M counterparts.

Update: Intel asked us to change GPU from original article to Intel graphics as it finds it irritating? We did changed it as Clardales graphics performance is an insult for any GPU and doesn't deserves a name.
