Have you ever wondered how a computer can handle high-end graphics? Or what is the difference between a computer you use every day and computers used in film studios? The answer is Graphical Processing Unit (GPU). GPUs have become increasingly essential and distinctive features of modern-day PCs. Since GPUs have always been expensive, one must make the right choice before investing. GPUs are high in demand; therefore, product research is essential to make the best buy suited to your budget.
One can measure the performance of a GPU in various parameters like GPU clock speed (MHz), Amount of available memory, Memory clock rate, and Memory bandwidth (GB/s). There are many advanced GPUs in the market like Nvidia GeForce RTX 3080 10GB, AMD Radeon RX 6800 XT, AMD RX 6500 XT, Nvidia GeForce RTX 3060 Ti, and Nvidia GeForce RTX 3070. The factors mentioned above impact the GPU performance in the following ways:
GPU’s architecture plays a crucial role in determining the efficiency of a GPU. Analogically, it is similar to the foundation of a building. The stronger the foundation, the higher load it can bear. A GPU is responsible for running several parallel processes at once; therefore, using a GPU with advanced Architecture would increase the computing power. The latest breakthrough in GPU Architecture is comparable to AMD RDNA™ 2 technology used in AMD RX 6500 XT.
GPU Clock Speed
GPU Clock speed indicates the speed at which the GPU cores process the data. It is measured in Megahertz (MHz). Faster GPU enables gamers, image editors, and renderers to have a seamless experience using high-end applications. Overclocking GPU clock speed can also help meet the demands of a higher-end application that was earlier underperforming on the existing setup.
Amount of available memory
GPU memory is responsible for storing high-end graphics, details, textures, etc. In high-end graphics mode, the available memory determines how the application would run. It is recommended that for gaming and rendering processes, the suggested memory size should be 6 GB to allow a seamless experience.
Memory Clock Rate
The memory Clock rate determines the speed of VRAM. VRAM stands for Video-Random Access Memory. It is the RAM of the GPU. It stores the required information for the GPU to display rendered images and videos. Faster memory clock rates allow it to store and disseminate information faster. A reasonable memory clock rate complements the GPU clock speed, and if it is lower, then the performance of the GPU is impacted.
Memory Bandwidth helps in increasing the rate of data being stored. Complementary to GPU’s drawing speed, both are responsible for the smooth delivery of high-resolution graphics. It would not impact the quality of the graphics. Memory bandwidth would determine only the rate at which the result is achieved.
As you have seen, the process of selecting the ideal GPU for your computer is very comprehensive. There are various parameters mentioned above that will help in making the right choice.
It shall also be noticed that since the demand for GPU is sky-rocketing, there can be a situation where one has to compromise for an older version of the GPU to make up for availability and budgetary restraints.
Therefore, the best GPUs to buy in 2022 should possess an ideal combination of the above parameters and be budget-friendly, both of which can be obtained by conducting product research and pre-ordering it on official websites.
