Video card is a processor whose sole purpose is to handle video feeds for a display output device. With time these processors gained its importance and hence its power to take care of more load, that is, more the GPU or Graphics Processing Units’ memory, it is able to feed more pixel information to the display device.
Of this huge market, filled with various GPUs, it is indeed tough to choose one for yourself, which, will keep a balance of both budget and performance. It is advised to have a budget of one-third of the whole computer for the graphics unit since it’s the beauty of the displayed output, which would matter in due time. A little knowledge about the technicalities and thereafter a little hint will make your buying experience easy. Before jumping into specifics of a model, it would be sage to make you aware of the terms like ram memory type, bandwidth, refresh rates, and clock speed. If you like to be able to do some gaming while travelling you should look for a gaming laptop. For some good advice on what to look for and also some specific laptop recommendations, have a look at this list of the best gaming laptops under $1500.
Clock speed is the time required to process one information. It’s expressed in terms of frequency to make it presentable (seconds will be in order of E -6, and faster the CPU, lesser will be time, inconvenient to express), and to make calculations easier. Factory overclocked unit, sounds awesome, but they are not as good performers as their later higher models, plus it heats up quicker, and is more power craving than the immediate naturally clocked model.
RAM memory type and amount
An amount of physical memory is embedded in the GPU which is required to store the pixel – wise information and flush it into the screen, hence larger the pixel density, more is the RAM required, that is small displays are quite okay with lesser physical memory, whereas you might even need multiple graphics units for 4K displays, hence getting excited for the amount of physical memory a GPU makes no sense. Also, memory types DDR, DDR2, DD3, DD4, DDR5 etc. are available, where DDR means Double Data Rate, which means it will transfer two memory value in one clock cycle, and the trailing digits refers to the number of SDRAMs or Synchronous Dynamic Random Access Memory, present. Hence it’s no brainer to understand that more the number of RAM groups, more is the bandwidth (next heading to make you understand better) or data transfers per second.
One clock sweep will gather a set of information (that is bits) to transfer, therefore, the amount of data bit transfers taking place in a second is called the Bandwidth. This is the most determining factor for anything. For instance, a 5GB DDR2 GPU looks nice, but a 1GB DDR5 is infinitesimally better because it can handle more data in the same amount of time. For example, if a video card with 200 MHz of type DDR video RAM, which is 128 bits wide then it has a bandwidth of 6.4 GB/s, since it’s DDR, it’ll transfer twice of 128 bits, therefore (128*2) bits * (200 *1000000) Hz = 51200000000 bits per second = 6.4 GB/s.
It’s the speed at which the screen refreshes itself to display the next new image. Higher refresh rates and higher FPS or Frames per Second is required to avoid lags, screen tearing, and stutter. Basically when the program initiates a draw, that is drawing a frame to be presented on screen, but the screen is not yet presented since the screen refresh did not take place, which is therefore called lag, sometimes, portions of the screen gets updated to the new frame, which causes screen tearing.
Also, with advancements of technologies, graphics processors are made to work at par with CPUs to increase performance. Image processing, video rendering being the primary objective, the GPU cores perform tasks in parallel fashion and are faster. CPU performs in serial way to work out the calculation, but technologies like CUDA, and APUs, have hit the market to make computers at least 50 – 60 times faster.
Things to keep in mind:
- Space inside cabinet: The GPU card sizes matters, sometimes it doesn’t fit in the cabinet, take a measure before you spend your hard-earned money. Cooling Systems and higher power supply units might need an extra space.
- Power consumption: Compare your power sources power dispensing capabilities, if it didn’t sign up for powering GPU level load, you might have to upgrade, also high-end GPUs require power conditioning to save itself from voltage fluctuations, thereby buying a trusted power supply will dispense sustained power into the GPU.
- Compatibility with other components: Other components should be as good as your GPU to help you get the best out of your rig, you can’t expect a Pentium Dual Core to keep up with latest GPUs, same goes for RAMs and motherboards, every component has its role and all should be at par to give you the right output, more and less of each other can cause compatibility issues.
- Cooling systems: High performing GPUs often use up a lot of power and get heated up soon, if they are not cooled evenly, they will not perform up to the mark, hence will cause lag and stuttering, also might get too worked up and fail the electro
- Multi – Graphics Units, are not better: If you don’t have a huge display like 4K displays, you are better off with a single higher performing unit. Because different cards would have even the slightest differences, which will cause the other to lag, power dispensing fails, etc. and twice the cards won’t result in twice the performance, it’ll increase the performance to a max of 50%. The Higher addition of which decreases the amount of extra advantage.
