14 DAY TRIAL // Intel's Haswell architecture will soon extend to the embedded market, where chips like the Core i3-4100E, i3-4102E, i5-4400E and i5-4402E will make their rounds soon enough.
We've known about these CPUs since last month, but the initial leaks didn't have all the relevant technical details.
The information is available now, though, courtesy of data sheets of DFI and EKF industrial products, which CPU World looked at.
The processors, despite being divided into two pairs (Core i3 and Core i5), are quite similar in several respects.
First off, they all have two physical cores and four logical cores, thanks to the Hyper-Threading technology.
Secondly, they all have 3 MB of L3 cache memory. Not too much but not too little either. Just enough for embedded applications.
Thirdly, all four CPUs possess GT2 integrated graphics processors (iGPs) clocked at 400 MHz, or 900 MHz in Turbo Mode.
A fourth similarity is in the memory controller. The central processors all get DDR3L-1600 memory support.
Thus, only the clock speeds and the TDP (thermal design power) set the chips apart. Those, and the Turbo boost technology only found on the Core i5 models.
Core i3-4100E is a 2.4 GHz unit with a TDP of 37W, while the Core i3-4102E is a 1.6 GHz chip with 25W TDP.
Finally, the Core i5-4400E is a 2.7 GHz / 3.3 GHz model with 37W TDP, while the Core i5-4402E runs at 1.6 GHz / 2.7 GHz and has TDP of 25W.
The Core i5 units also possess Trusted Execution and VT-d virtualization technologies, plus AES instructions. The Core i3 only get PC Express 3.0 interface and support for SSE4 and AVX instructions (obviously, the Core i5 duo get them too).
The four CPUs will be officially introduced at the start of the fourth quarter, so in October 2013.
