In the previous post, we have seen that what are super computers and what are their uses? In this post we will see the top 10 super computers in the world…………..

• Rank 10 – Trinity – 8.1 petaFLOPS – U.S.
• Rank 9 – Mira – 8.5 petaFLOPS – U.S.
• Rank 8 – K computer – 10.5 petaFLOPS – Japan
• Rank 7 – Oakforest PACS – 13.5 petaFLOPS – Japan
• Rank 6 – Cori – 14 petaFLOPS – U.S.
• Rank 5 – Sequoia – 17.1 petaFLOPS – U.S.
• Rank 4 – Titan – 17.5 petaFLOPS – U.S.
• Rank 3 – Piz Daint – 19.5 petaFLOPS – Switzerland
• Rank 2 – Tianhe 2 – 33.8 petaFLOPS – China
• Rank 1 – Sunway Taihulight – 93 petaFLOPS – China

China has topped the list with the fastest super computer in the world and the cost of “TaihuLight” which is the fastest super computer on this planet is $ 273 million or Rs 1780 crore.

Super computers are the special type of computers who’s processing speed is extremely large than normal desktop PC. But why we need them? and who uses such a huge and powerful computers?

We need such type of huge and powerful machines for some specifics functions like simulation of universe over millions of years, safety and reliability of nuclear weapons, highly sophisticated scientific and mathematical calculations, bioinformatics, climate change observations, geo-scientific exploration and many other complex tasks which are literally impossible for normal desktop computer.

Next thing is how we will measure the speed of super computer? Will we have to see the clock speed or what? Answer is No. Super computer’s speed is measured in petaFLOPS.

1 petaFLOPS is equal to 10^15 floating operations per second.

You can understand it by imagine if you will do a one calculation every second for next 31,688,765 (Three crore sixteen lakhs eighty-eight thousand and seven hundred sixty five years) continuously without stopping, Super computer with 1 petaFLOPS speed will do it in just 1 second………….that much fast

In the next post we will see the top 10 super computer present in the world in 2017.

I hope you all know about the mother-boards.

For those who don’t know about the mother-boards, they are PCB (Printed Circuit Boards) which holds the processors, memory units and other peripheral devices in the computer and allows the communication between them.

So which company’s mother-board are you using in your laptop/ PC? If you don’t know check it, but after reading this article…..

Here is the list of world top 5 mother-boards manufacturers.

• Asus (Taipei, Taiwan)
• Gigabyte Technology (Taipei, Taiwan)
• MSI (Zhonghe, Taiwan)
• Intel (California, U.S.)
• AS Rock (Taipei, Taiwan)

As you can see Taiwan has 4 out of 5 top manufacturers of  the mother-boards in the world.

Are you getting confused which processor or GPU should you buy or how much RAM should you choose.

No worry I will solve your problem.

First we will have to decide what you are going to do with your PC. So I have divided people in 3 categories.

1) Office going and school/college students : Those people who uses MS word, excel, power-point, do emails, playing low level games etc.

• You should use Intel core i3 (choose newest generation) because core i3 is perfect for office work and projects of school/college students.
• Many PCs vendors provide integrated graphics but if your PC haven’t even the lower level one then you can take any low level GPU (graphics processing unit) like NVIDIA GeForce GT 1030 for PCs.
• 4GB of RAM will be good but if you can upgrade 8GB will be more than enough.
• In the last you can change your magnetic hard disk drive with SSD (solid state drive) because SSDs are approx. 10x times faster than 7200rpm magnetic hard disk drive. But this is optional because the price of SSDs are quite high but when you will replace you will notice fast booting, extremely fast file transfer, fast applications response etc. 120GB- 250GB SSD will be enough for you if you don’t store too much movies on your pc.

Avg. cost of laptop or pc in this category will be Rs 25000- 30000 (with SSD).

2) Medium level gamers or video editing or 3-D rendering :

• You should choose Intel core i5 (newest generation that you can get, preferred 8th gen.).
• For graphics you can take NVIDIA GeForce GTX 1060-6GB
• 8GB RAM will be good but if your pocket allows you can upgrade to16GB.
• You should use SSD of around 250GB or higher if possible for the same previous reasons because it will be give you great gaming experience. Don’t choose magnetic hard drive.

Avg. cost of laptop or PC in this category will be Rs 60000 – 80000 (with SSD).

3) High level gaming or video editing or 3D graphics rendering :

• You should choose Intel core i7 (newest generation that you can get preferred 8th gen.)
• For graphics you can take NVIDIA GeForce GTX 1080 8GB or AMD Radeon RX VEGA64  8GB.
• 16-GB RAM will be good but you can take beyond it upto 32-GB if you have good quality mother board and other components that would support it.
• You must choose SSD of around 500GB or more for your system and shouldn’t choose magnetic hard drive as it will hinders in your systems performance.

Avg. cost of laptop or PC in this category will be Rs 100000+  (with SSD).
