What Factors Affect the Performance of GPU?

Abby Hill | Updated On December 21, 2023

How GPU performance is affected by TDP, clock frequency, GPU supply voltage or memory bus width. Whether the number of RT cores directly affects the speed of graphics created using ray tracing, or whether other elements have a key impact. How much do specific GPU blocks affect card performance? How to proceed when you are out of hashrate and you need it badly? Size, cooling, noise. 

Even the most trivial considerations should be taken into account when deciding to buy a new graphics card. Before buying, therefore, let’s check the size and length of the components in terms of their placement in the case. The largest GTX models can occupy almost three slots and can be as long as 30 cm. To this must be added the space between other components to allow for free air circulation. If you are replacing a graphics card or building a new PC from scratch, check whether the components will fit in the case.

Graphics card manufacturers design their own cooling systems, which comprise proprietary technologies based on heat pipes, heat sinks and fans to dissipate heat and cool the graphics system. Graphics rendering components can generate temperatures in excess of 80 degrees Celsius and even oscillate around 100 degrees during intensive and prolonged gaming. This is why cooling is so important – and not just for the graphics card, but also for the entire computer. When your GPU is low-quality, it is a good solution to learn about lease gpu.

Overclocking?

Within the same chip, different graphics card models have different core clock speeds in megahertz (MHz). Clock speeds translate into processing power and therefore performance, so comparing two or more products is an easy way to check their capabilities.

Most GeForce graphics cards have overclocking capability. With this procedure, it is possible to increase the core clocking and thus increase the performance of the GPU. If you are interested in OC, it is worth looking for a model that allows you to carry out this process to a greater extent.

What are the Advantages of Combining Graphics Cards?

It is most common to combine two graphics cards, although it is possible to combine three or even four at the same time. What kind of performance increase can be expected from combining GPUs? A layman might expect it to be 100 percent, as we are theoretically using two GPUs simultaneously. However, the matter is somewhat more complicated.

The computer does not use the full power of both GPUs working in tandem. This is because the second card plays an auxiliary role, supporting its twin in carrying out computational operations. The achieved power gain in such a configuration depends on a number of factors and can range from several to tens of percent.

In games, the situation is even more different. If we play with well-optimised productions, we get great results. If a title does not support dual graphics cards, we will even see a loss in the fluidity with which the graphics are displayed, compared to a single GPU. Other way round is the possibility of GPU server rental. In such a way it is possible to get connected with a supercomputer network and use its hashrate for its own goals.
