Samsung has launched the Exynos 5 series 7872 SoC recently. This SoC is not as good as Series 9 9810, which is designed for high end smartphones. It has been designed for the medium level smartphones which would be in budget of most of the people.

Fabrication: It’s based on 14 nm FinFET fabrication process which gives it high density and low power consumption as compared to previously launched SoC in its series.

CPU: Exynos 7872 has Hexacore CPU consisting two Cortex A73 cores clocked at 2 GHz and four Cortex A53 clocked at 1.6 GHz to provide it a balance between performance and power saving mode.

GPU: It has the ARM’s Mali G-72 which is not the latest but would provide a descent performance in mid range smartphones.

Modem: Exynos 7872 comes with LTE Cat 7 modem which is capable of 300 Mbps download speed and 150 Mbps upload speed.

Camera: Exynos 7872 can support 21.7 MP front as well as rear side cameras which is good for the mobiles in the mid range budget.

Video: It can record upto 1920x 1200 pixels at 120 fps (Frames Per Second) full HD video.

Bluetooth: It comes with Bluetooth 5.0 which is the latest Bluetooth version in smartphones.

Security: It is capable of handling high end security features like iris scanner.

Overall, It is a good quality SoC from Samsung for the mid range smartphones which you would see in the series of phones by the companies like Meizu, Lenovo etc.

A Graphics Processing Unit (GPU) is a specialized circuit designed to rapidly manipulate and later memory to accelerate the building of images to display.

In recent years, due to advancement in technology, there has been huge increase in the GPU transistor number count which is making the Moore’s law possible even in that much small area.

Here is the list of some GPUs with their transistor count, release date, manufacturing company and fabrication size.

• NV3 – 3,500,000 – 1997 – NVIDIA – 350 nm
• R100 – 30,000,000 – 2000 – AMD – 180 nm
• NV38 – 135,000,000 – 2003 – NVIDIA – 130 nm
• G86 Tesla – 210,000,000 – 2007 – NVIDIA – 80 nm
• RV710 – 242,000,000 – 2008 – AMD – 55 nm

• Cedar RV810 – 292,000,000 – 2010 – AMD – 40 nm
• Caicos RV910 – 370,000,000 – 2011 – AMD – 40 nm
• GK107 Kepler – 1,270,000,000 – 2012 – NVIDIA – 28 nm
• Bonaire – 2,080,000,000 – 2013 – AMD – 28 nm
• GP106 Pascal – 4,400,000,000 – 2016 – NVIDIA – 16 nm
• GV102 Pascal – 12,500,000,000 – 2016 – NVIDIA – 16 nm
• GV100 Volta – 21,100,000,000 – 2017 – NVIDIA – 12 nm

So, Now you can imagine technology has reached upto which end and how fast it is still growing………

A Field Programmable Gate Array (FPGA) is an integrated circuit designed to be configured by a customer or a designer after manufacturing.

Here is the list of some FPGA’s with their transistor count, release date, manufacturing company and fabrication size.

• Virtex – 70,000,000 – 1997 – Xilinx
• Virtex II – 350,000,000 – 2000 – Xilinx – 130 nm
• Virtex 4 – 1,000,000,000 – 2004 – Xilinx – 90 nm
• Stratix IV – 2,500,000,000 – 2008 – Altera – 40 nm

• Stratix V – 3,800,000,000 – 2011 – Altera – 28 nm
• Arria 10 – 5,300,000,000 – 2014 – Altera – 20 nm
• Stratix Family device – 17,000,000,000 – 2017 – Intel (Formerly Altera) – 14 nm

Special property of FPGA is that we can designed them after purchasing them according to our need which makes them highly customizable.

Tile is a San Mateo, California based electronics company which manufacturers consumer electronics products.

Tile has it’s IoT based key finder device series which uses Bluetooth 4.0 for the connectivity. Basically tile key finder device work with your Android or iOS device to find or locate your lost keys with ease. After it’s launch in 2015, tile has sold over 4.5 million units by 2016.

Hardware Features:

• Size of tile key finder is very small, 1.5 square inches.
• Inbuilt battery that can run for over 1 year duration
• Water proof hardware design
• It has inbuilt Bluetooth Low Energy 4.0 chip (to communicate with other devices like your smartphone) which comes with 150 ft. Connectivity range

Functioning: As mentioned earlier, it uses Bluetooth connectivity for pairing. Let’s suppose you lost your key or camera or purse or anything else. By using mobile app you can ring this smart device which produces sound of 90 decibels of volume intensity which is enough to find where the device is?

But what will happen if you crossed this limit. Still can you locate it? Absolutely, because if the tile will come in contact within the range of other tile app activated device, it will send the messages regarding its location to the owner so that he/ she could find it.

Application: You can use it for daily life thing. One tile app account can connect up to 8 tile devices.

Specially useful if you are working where there is a lot of stuff in which your important things can get misplaced.

Conclusion: Overall good product. But I wouldn’t suggest for those who want to use it for daily use because this device will make your things forget easily since you will become dependent on it.

But you can use at places as I already mentioned where there are a lots of things like construction places, boutiques etc.

Bixi was introduced by the Bluemint labs (France). Bixi is an IoT (Internet of Things) based product that can be used to do things with just simple gesture or board movements.

Bixi is a gesture device that uses Bluetooth 4.1 Low Energy to communicate with other devices with a range of approx. 20 meters and has approx 1 month battery life.

Functioning: Bixi has different types of gestures such as Double tap, Wave up, Wave down, Raise/ Lower, Wave right, Wave left which can be used by the user to perform different task with just doing simple gestures.

Here is the list of few tasks that can be done by Bixi:

• Play/ Pause music
• Change music
• Activate google or Alexa (on echo smart speakers)
• Getting/ navigation directions
• Open smart door
• Take/ Rejecting calls
• Turn off alarms
• Send messages
• Controlling connected cameras
• Controlling lights and lot more others

Bixi gadget which uses gesture control technology is compatible with 100+ devices. Bixi also has an inbuilt microphone which means you give commands to your other devices like google home, smartphones etc. With it.

Application: Bixi is useful at the places where you can’t touch your phone like while doing cooking and other similar tasks etc. Because doing so can make your phone dirty. When driving because use of mobile phones are also not legal white driving and can cause severe accident.
