Smart Locks Explained

Bring your home security into the 21st century

One of the latest security gadgets to make its way into the home is the smart lock. Using connected technologies, smart locks allow you to open doors without the need for keys. But how do they work? Are they safe? And what are the benefits? Here, we’ll tell you.

Intel Core i7-5930K 3.5GHz

Toward the end of 2014, Intel released a trio of fourth-gen Extreme processors: the i7-5820K, the i7-5930K and the i7-5960X. These are the premium end of the processor scale, so you can expect to pay a pretty penny to get your hands on one.

The i7-5930K is a beast of a CPU. A six-core, 12-thread powerhouse, with a base clock speed of 3.5GHz and an oddly meagre turbo boost of just 200MHz to 3.7GHz.

Intel Core i7-4790 3.6GHz

This i7-4790 is a fourth-gen Intel Hyper-Threading processor, having been released around mid-2014. It features a base clock speed of 3.6GHz, a turbo clock speed of 4GHz for one of the cores and 3.8GHz across all four cores.

The TDP is a little higher than the sixth-gen i7 processors, those being around 65W as opposed to this model's 85W. The integrated GPU in this case is an Intel HD 4600, which manages a base clock speed of 350MHz and a turbo boost speed of 1.2GHz – exactly the same as the i5-4690K that came out at around the same time.

Intel Core i5-6500 3.2GHz

Pitched at a point above the i5-6400 is the i5-6500, another sixth-gen Intel processor that takes the benefits offered by the more entry-level i5-6400 and adds a couple more enticing elements to the mix.

This is a 3.2GHz 64-bit processor, with four cores, 6MB of L3 SmartCache and a turbo frequency of up to 3.6GHz. Since it’s a sixth-gen model, there’s support for DDR4 memory up to 1866/2133MHz, a TDP of 65W and an integrated Intel HD 530 GPU.

Intel Core i5-6400 2.7GHz

The i5-6400 was released toward the end of last year and sits neatly in the mid range of Intel’s desktop processor series.

It's based on the Skylake architecture, so this particular 64-bit chip uses a 14nm manufacturing process, together with other such features as 6MB of L3 SmartCache, 1MB of L2 cache, support for DDR4 1866/2133 memory and an integrated Intel HD 530 GPU, which runs at a base frequency of 350MHz and a boost frequency of 950MHz.
