Hey Friends!.All Of you people use computer,laptops etc. You All know components of computer i.e. Motherboard,Processor or CPU,RAM,Hard Disk, Graphic Card or GPU etc.Most of you know about configuration of Processor,RAM, etc, so you can easily compare them But Graphic Card is one of the confusing device.Many people doesn't know how to compare Graphic Cards. There is a myth that 2GB of a Graphic Card is better 1GB Graphic Card but it is not.There are many questions related to that.Lets see some common questions..
Q. How Does A Graphic Card Works ?
A. A Graphic Card consist of a processor that processes the graphics and a video memory or video ram
in which it store them temporarily. There are two type of GPUs IGP(Integrated Graphic Processor)
DGP(Dedicated Graphic Processor) .The first one also known as chipset is integrated in motherboard
so called integrated processor.The other one is connected from outside through a port called PCIE
port and needs an external power supply.The graphics is processed by core clock and written into
video ram.There is another term Shaders. Shaders are actually that part which control the pixels of
graphics.
Q. How To Check Specification Of Your Graphic Card ?
A. You can use a simple tool as gpu-z. It will show the properties of your Graphic Card like this.
You can download it here: gpu-z 0.6.3
Q.How To Compare Two Graphic Card ?
A.To compare the two Graphic Cards we should first look at the memory type.There are basically three types of memory types are popular DDR3,GDDR3,GDDR5. The GDDR3 type memory is two times faster than DDR3 and GDDR5 is two times faster than GDDR3.Now you should look at the clocks Core clock and Memory clock both are important.The GPU having Core Clock more in same memory type will be good i.e If there are two GDDR5 cards one with 700MHz Core Clock size 2GB and other with 900Mhz Core Clock and size 1GB ,The card with 900Mhz will perform better.The next feature you should see is Bandwidth the GPU having more bandwidth will perform good.The video RAM size only matters when Display Resolution is large.But if there are same GPUs having same core clock same memory type same Memory Clock than 2GB version will definitely will perform better.
Things You Should Keep In Mind:
- If You are going to buy a laptop than you should prefer the laptop having better gpu because we usually coudn't use whole of Intel Core i5 or i7 but your gpu will be eaten up.
- The most expensive component of computer is Graphic Card.
- Prefer system with Core i5 and GDDR5 GPU than core i7 and DDR3 GPU.
