Starts at 2.9GHz and stops at 3.6GHz
All you need to have a properly fast notebook these days is a Core i5 /Core i7 17W CPU and from our experience, the 1.8GHz Core i7 2677M works just fine.
If you need more power it can overclock with turbo all the way to 2.9GHz, which is staggering for low voltage parts. However, these numbers are not enough in the low power desktop market, and Intel plans to launch a 35W T-series dual-core that should provide unparalleled performance at 35W.
The official name is Core i5 3470T and it has two cores and four threads. The base clock is 2.9GHz but with turbo it can get all the way to 3.6GHz. It has 3MB cache and it replaces the Core i5 2390T, 2.7GHz clocked dual Sandy Bridge with turbo speed of 3.5GHz.
Once it is ready, the Core i5 3470T will sell for $184. In case two cores are not enough for your needs, you can get a quad core with eight threads Core i7 3770T clocked at 2.5GHz, with an impressive 3.7GHz on turbo. The TDP is only 45W.
So, Ivy Bridge power consumption looks really nice and the figures seem to prove that Intel will be able to roll out power efficient desktop chips with TDPs that could even work in the mobile market. In fact, 35W and 45W are still commonplace in notebooks, yet with the 22nm process Intel is capable of churning out a quad-core that can clock all the way up to 3.7GHz. Not that long ago, such frequencies were reserved for overclockers with bulky cooling systems and chips with three-digit TDPs. Pretty soon, all you will need is a cool and quiet 45W part.
