7 Ultrabook Processing Platform Candidates

Posted on 22 June 2011 By


I’m typing this article on a 1.4Ghz Core i5 2357M device. It’s fast and efficient and representative of the type of performance that you’re going to get from Ultrabooks. It’s not quite the platform that the Asus UX21 will use when it launches though. On that you can expect one of the three new Sandy Bridge ULV (Ultra Low Voltage) CPUs that CNet highlighted today. There are two additional Core i3 parts I see too which brings the total to 8 CPU/GPUs, one of which is for embedded markets.

The three parts reported by CNet today are:

  • Core i7-2677M: 2 cores, 1.8 GHz (Turbo to 2.9GHz), 4MB cache, 17 watts TDP
  • Core i7-2637M: 2 cores, 1.7GHz (Turbo to 2.8GHz), 4MB cache, 17 watts TDP
  • Core i5-2557M: 2 cores, 1.7GHz (Turbo to 2.7GHz), 3MB cache, 17 watts TDP

The two new Core i3 parts are

  • Core i3-2340UE : 2 Cores, 1.3Ghz (No Turbo), 3MB Cache, 17 Watts TDP (For embedded applications)
  • Core i3-2357M : 2 Cores, 1.3 Ghz (No Turbo), 3MB cache, 17 Watts TDP

The three existing parts are

  • Core i5-2357M: 2 Cores, 1.4Ghz (Turbo to 2.3Ghz), 3MB cache, 17 Watts TDP (As seen in the Samsung Series 9)
  • Core i7-2677M: 2 cores, 1.8Ghz (Turbo to 2.9Ghz), 4MB cache, 17 Watts TDP
  • Core i7-2657M: 2 cores, 1.6Ghz (Turbo to 2.7Ghz), 4MB cache, 17 watts TDP

The Asus UX21 will use the Core i5-2557M according to Cnet. It’s likely that the 2375M Core i3 part will be used in lower-cost products. Note that although it doesn’t have the Turbo technology, it does have speed stepping.

TDP stands for Thermal Design Point or Thermal Design Power. It’s not an indication of potential battery life, it’s an indication of the heat dissipation that might be experienced under full load.

    The i5-2557M seems to be the sweet spot there, as it should be affordable, powerful with a low TDP

      Yeah although it’s interesting because most people will use these devices in balanced mode which means it makes very little difference. In high-load scenarios, that’s where the difference will be felt. I feel that cost is going to play a big role with Ultrabooks.

    Thanks Chippy! It would have taken me a while to write up this info. That’s why I follow your posts! To me, they provide helpful information.
