V-ram vs Cuda Cores vs Clock Speed is some kind of topic that I guess everyone should know about if you're getting into the world of processors, Graphic cards, etc. Right now there is a lot of confusion created in the minds of people about whether they should purchase their ideal gpu based on V-ram, Cuda Cores or Clock Speed let me tell you guys one thing Cuda Cores and Clock Speed are the 2 things or two aspects that are required the most for let me give you a simple example (p.s. compare your body with graphic card and V-ram with a gym trainer ) think as if you have a decent physique but need a little shape to it to improve looks so you join a gym so in this condition what will you prefer to hire 3 to 4 trainers or just one trainer to just guide you? - It's simple that you would choose a single trainer. The same applies here if you have a good graphic card you should go with a decent amount of Vram like 8 GB, and 4 GB Vrams are right now enough to run high-quality games on high to medium settings until and unless you are not a game producer. But what is most necessary are the Cuda cores and the clock speed which I will be comparing with the strength and the capacity of your body which are really highly needed. Now to get a little deeper which will help to decide to choose what.
Vram
Vram is also called the Video RAM or the Video Random Access Memory. A Vram is used to convert the digital signals it receives to analog signals so it is also called the RAMDAC i.e. RAM Digital - Analog Converter. Digital signal is converted to analog signal and they are directly sent to the display as these processes are so fast that you won't even find a single flicker in it. Vram as soon as it gets the graphical image helps to read and write it as quick as it can. 4 types of VRAM are present in SGRAM i.e. Synchronous Graphic RAM which helps you to read, write, and update the data as fast as possible. RDRAM i.e. Rambus Dynamic RAM helps you to transfer the data from one source to the destination quickly. WRAM i.e. Window RAM helps you to make streaming with optimized video quality as this VRAM is a heavy memory monger compared to other types of RAM. The last type is the MDRAM Multi-Bank Dynamic RAM which helps to break down the large data chunks into smaller ones so that the data transportation can be easily carried down. Over all a VRAM helps you to increase the speed of the data processing.
Cuda Cores
Cuda (Compute Unified Device Architecture) Cores the miniature or the smaller part of the whole graphic processor which is embodied on the GPU. There are almost thousands and in some low-end GPUs, there are hundreds of Cores embodied. These cores are very helpful to render all the graphical structures you find on the screen. "Cuda Cores" is of Nvidia which is as same as the AMD "Stream Processors". The Cuda Core is the parallel computing programming model that can leverage the GPU in specific ways to perform tasks with greater performance. Architecture changes in a fashion that makes cross-generation comparisons often non-linear, but generally speaking (within a generation), more CUDA cores will equate to more raw compute power from the GPU. The Kepler to Maxwell architecture jump saw nearly a 40% efficiency gain in CUDA core processing ability, illustrating the difficulty of linearly drawing comparisons without proper benchmarks.
Cuda Core renders an image with the help of calculating a matrix of any image's pixel. So that you can get the highest quality of any image.
Clock Speed
This is an aspect which is the most important aspect of the whole graphic card performance as this defines the performance capacity and ability of a particular graphic card. You may have seen the Mhz or Ghz written in the graphic card specs which itself means the clock speed of any GPU. Clock speed is always measured in terms of Mhz or Ghz. 1Mhz is one million cycles per second and 1Ghz means one billion cycles per second which means 1Ghz is twice as fast as any 900 Mhz speed.
SO DECIDING ON WHICH BASIS YOU SHOULD BUY YOUR GRAPHIC CARD DEPENDS ON YOU FOR WHAT YOU ARE BUYING FOR, IF IT IS TO GAME YOU PREFER THE GRAPHIC CARD ON RHE BASIS OF CUDA CORE AND CLOCK SPEED WITH DECENT VRAM. BUT IF YOU ARE BUYING IT FOR THE GAME DEVELOPMENT YOU WILL NEED TO HAVE GOOD VRAM AND ALSO GOOD CUDA CORE WITH HIGH CLOCK SPEED.
