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.
