Intel is updating its notebook chip family with a number of slightly faster Haswell and Bay Trail processors including 7 new chips aimed at relatively low-power portable notebooks or 2-in-1 systems.
There are 4 new Bay Trail chips which use 7.5W or less, and 3 new 28W Haswell ULV (ultra low voltage) chips for higher-performance devices.
These new processors give modest speed bumps to existing chips but otherwise they look a lot like their predecessors, so don’t expect any major new features.
Here’s a quick run-down of the new processors:
|Celeron N2808||2||1.58 GHz / 2.25 GHz||1MB||311 MHz / 792 MHz||4.3W|
|Celeron N2840||2||2.16 GHz / 2.58 GHz||1MB||311 MHz / 792 MHz||7.5W|
|Celeron N2940||4||1.83 GHz / 2.25 GHz||2MB||313 MHz / 854 MHz||7.5W|
|Pentium N3540||4||2.16 GHz / 2.66 GHz||2MB||313 MHz / 896 MHz||7.5W|
|Core i5-4278U||2 / 4||2.6 GHz||3MB||28W|
|Core i5-4308U||2 / 4||2.8 GHz||3MB||28W|
|Core i7-4578U||2 / 4||3 GHz||3MB||28W|
These are all 64-bit chips, and the Haswell models support up to 16GB of RAM while most of the Celeron chips can work in systems with up to 8GB. The Celern N2808 tops out at 4GB. That chip will most likely be used only in low-cost notebooks, Chromebooks, tablets, or 2-in-1 systems.
