Back in March of this year, Intel launched a slew of third generation Core Ivy Bridge processors. At the high end sat the Core i7-3770K with 4 cores, hyperthreading, 3.5 GHz clockspeed (3.9 GHz Turbo Boost), 8 MB L3 cache, and a 77W TDP for $332. 
The lineup went down in features – and price – from there all the way to the Core i5-3330S. The 3330S had four cores, 6 MB of L3 cache, a 65W TDP, and a clockspeed of 2.7 GHz (3.2 GHz Turbo Boost). Further, just about every CPU that was not a K, S, or T edition came equipped with the older HD 2500 integrated processor graphics. While the list comprised 18 new processors, the lower-end Core i3 Ivy Bridge CPUs were noticeably absent.
Fortunately, FanlessTech has managed to get ahold of pricing and specifications for five of those lower cost Intel chips. The new additions to Intel's lineup include three Ivy Bridge processors and two Sandy Bridge CPUs. Specifically, we have the i3-3240T, i3-3220T, Pentium G2100T, Pentium G645T, and Pentium G550T. All of those parts have a TDP of 35W and are priced very affordably.
| Model | Cores / Threads | Clockspeed | L3 Cache | TDP | Launch Price ($USD) | |
| i3-3240T | Ivy Bridge | 2/4 | 2.90 GHz | 3MB | 35W | $138 |
| i3-3220T | Ivy Bridge | 2/4 | 2.80 GHz | 3MB | 35W | $117 |
| Pentium G2100T | Ivy Bridge | 2/2 | 2.60 GHz | 3MB | 35W | $75 |
| Pentium G645T | Sandy Bridge | 2/2 | 2.50 GHz | 3MB | 35W | $64 |
| Pentium G550T | Sandy Bridge | 2/2 | 2.20 GHz | 2MB | 35W | $42 |
The Core i3-3240T and i3-3220T are dual core Ivy Bridge processors build on a 22nm process, and are priced at just over $100. The cheapest Ivy Bridge CPU is actually the Pentium G2100T at $75 so the barrier to entry for Intel’s latest chips is much lower than it was a few months ago. Intel’s second generation Core architecture is still alive and kicking as well with the Pentium G645T and G550T at $64 and $42 respectively.
Two specifications are still unkown: Turbo Boost clockspeeds (if any) and which version of processor graphics these chips will feature. On the graphics front, I think HD 2500 is a safe bet but Intel may throw everyone a curve ball and pack the higher-end processor graphics into the low end units – which are arguably the (computers) that need the better GPU the most.
Granted, these lower cost processors are not going to give you near the performance of the i7-3770K that we recently reviewed, but they are still important for low power and budget desktops. Bringing the power efficiency improvements of Ivy Bridge down to under $100 is definitely a good thing.
As far as availability, you can find some of the new low TDP processors at online retailers now (such as the Core i3-3220T), but others are not for sale yet. While I do not have any exact dates, they should be available shortly.
How would you put these low TDP dual cores to work?

Im planning to use a 35W Core i3 (Ivy Bridge) for a low power compact file server.
They are good for things where you need very low heat output.
Definitely, I bet you could
Definitely, I bet you could even get by with totally passive cooling on all the components :).
Those 35w CPUS would be
Those 35w CPUS would be perfect for building a 0dB passively cooled HTPC. There are quite a few great passively cooled HTPC cases about, like Akasa’s Euler.
They are not now cost parts,
They are not now cost parts, they are low-clocked versions which are / will be priced more. Just look at g620t vs. g620, i3 2100 vs. 2100t
