More Details on Ivy Bridge Models "S" and "T" Emerge

With the The First Intel Ivy Bridge CPU Clock Speeds and More story from earlier this week, we caught some of the early details of the first Ivy Bridge chips, which is set to release in April 2012. Now, with some more leaked information from Chinese site Corecn, via German site ComputerBase, we find out more information on S and T model numbers. 

The table provides a full listing of remaining eight upcoming models, including model number, base frequency, cache size, cores/threads, memory speed, turbo boost speeds, Intel HD graphics, frequency / dynamic frequency and TDP ratings. It appears that Ivy Bridge will have similar clock speeds to current generation Sandy Bridge CPUs, just with a lower TDP based on Intel's transition to 22 nm from 32 nm transistor design.

S - Performance-optimized (low power with 65W TDP), T – Power-optimized (ultra low power with 35-45W TDP)

Features shared by all the above mentioned Ivy Bridge CPUs are a 2-channel integrated memory controller; and all but the Core i5-3450S and i5-3330S have Intel's SIPP 2012, vPro 2012, VT-d, TXT, and AES-NI support.

    at the risk of sounding totally noob on this website, an inquiring mind wants to know: What happened to the GHz race? i thought we would be at 5GHz already :( . please no flaming, i sincerely want to know.

    The GHz race was the rage when performance scaled with frequency so the point was going up-up and of course going up meant power hungry and hot processors. But at a distinct point in time, a light bulb lit in one engineers head and he thought "what if performance can scale upwards with improvements in architecture rather than just plain speed". So back to the drawing board and there u have it, speed obtained through "cleverness" rather then "brute force".

    The GHz race died some 6-7 years ago when AMD figured out that they could kick intel's ass in optimizing design rather than raw speed. Then intel took that cue and came out with the Core solo/duo and Core 2 duo/quad and AMD has been playing catchup ever sense. Also they found that there are issues with power constraints and stability going past 5GHz, as the power requirement started turning exponential, and then running that much power causes damage to the processor so things start dying quickly.

    But ya, there was a time when the P4s were coming out that they thought they could push the micro-burst architecture to some 15GHz before they would have to change their processor design... obviously this did not work out.

    Looks like there's not much reason to upgrade from Sandy Bridge unless you really want that energy savings.
