Intel Core i5-750: Lynnfield with retail box and cooler pictured
According to media reports the Lynnfield CPU series will officially be introduced this week. PC Games Hardware already got pictures of a retail Core i5-750 and the according boxed cooler.
PC Games Hardware has already published tests of the Lynnfield CPUs, but now it seems like the official introduction of Intel's new processor series will take place this week.

Intel Lynnfield: Overview
Intel's Nehalem architecture is fast, but up to now only available in the high priced Bloomfield models also known as Core i7 for the socket LGA1366. With the Lynnfield core in combination with the socket LGA1566 the technology enters the mass market. For the time being the Core i5-750 will be the smallest available Lynnfield CPU. It matches the Core i7-860 but runs at only 2.67 GHz - like the Core i7-920 - and doesn't offer SMT, but the Turbo Mode increases the frequency up to 3.2 GHz.
The i7-860 has, like the i7-920, four physical cores and due to SMT four additional virtual cores. But it doesn't support Triple Channel memory and doesn't have a QPI connection to the rest of the system. Nevertheless the Lynnfield processors have an integrated PCI Express controller.
Another difference is related to the Uncore (L3 cache and Memory controller) sector: While the uncore frequency (UCLK) of the Bloomfield is at least four times as big as the real clock speed of the DDR3 memory (at DDR3-1333 at least 2666 MHz) and can be increased by adjusting the multiplier, the Lynnfield's UCLK is set to 2400 MHz - unless you overclock the reference clock speed (BCLK). The i7-860 is running at 2.8 GHz (133 x 21) and reaches up to 3.46 GHz in Turbo Mode - so the Lynnfield automatically overclocks itself by up to five multiplier points.
