What is a GPU
GPU’s are quite remarkable technology. GPU stands for the graphic processing unit. Generally, the graphic processing unit (GPU) )and central processing unit(CPU) are not very different.
For CPU’s, they are made of a few cores. They process data serially; that is it does one computation at a time whilst GPU which is made up of hundreds of cores they do the computation in parallel; that is they do all the computation all at once(these computations are usually very intense computations).
Uses of GPU
For good gaming experience;
GPU’s were created to do calculations that the CPU can’t normally do. GPU’s got their names from the gaming community. In some circles, it was referred to as the “gaming processing unit. It has evolved so much that gaming is no longer the focus of it. Currently, financial services, life sciences, healthcare are starting to get into it.
GPU’s have also found use in the field of artificial intelligence. Artificial intelligence has two part to it. Machine learning and Deep learning. There are GPU’s that are specially created for those applications.
GPU’s on cloud
mainly for the high performance, it offers. most Large companies that used a lot of on-premise infrastructure for any of their computation-intensive application.
What you need to know before buying GPU
|GPUs||price Class||Recommended Use|
|Nvidia GeForce GT 1030; AMD Radeon RX 550||Super cheap||Only buy these if you don’t game (or you don’t game much) and your CPU doesn’t have integrated graphics.|
|Nvidia GeForce GTX 1650 Super, Nvidia GTX 1650; AMD Radeon RX 5500 XT 4GB/8GB. |
Nvidia GTX 1060, GTX 1050 Ti and GTX 1050; AMD RX 590, RX 580, RX 570, RX 560
|Budget cards||It good for playing games at 1080p or lower res at medium-to-low settings|
|Nvidia GeForce GTX 1660 Ti, GTX 1660 Super, GTX 1660; AMD Radeon RX 5600 XT. |
Nvidia GTX 1070 Ti, GTX 1070; AMD RX Vega 56
|Mid-range cards||its perfect for 1080p gaming, compatible with VR headsets|
|Nvidia RTX 2070 Super, RTX 2070, RTX 2060 Super, RTX 2060; AMD Radeon RX 5700 XT, RX 5700. Nvidia GTX 1080 Ti, GTX 1080; AMD Radeon VII, RX Vega 64||High-end||Good for VR headsets and gaming at resolutions at 1440p or high-refresh 1080p monitors.|
|Nvidia RTX 2080 Ti, RTX 2080 Super, Titan RTX. Nvidia Titan 5, Titan Xp||Premium / Extreme||These are best for 4K, and the RTX cards support new ray-tracing and A.I. tech.|
AMD or Nvidia?
There are hundreds of graphics cards from dozens of manufacturers, but only two companies actually make the GPUs that power these components: Nvidia and AMD—although Intel’s Xe Graphics is also a thing.
AMD has competitive GPUs ranging from upper, mid-range, and budget GPUs, and the latest Navi-based RX 5000-series cards have mostly caught up with Nvidia on the power consumption front.
But on the very high-end of the market, Nvidia is uncontested as nothing from AMD can outperform the company’s faster RTX cards today. That may change once so-called “Big Navi” cards arrive, but the Nvidia Ampere GPUs are also coming.
Unless you need the level of performance you’ll get from something like an RTX 2080 Ti, the best reason to choose one company over the other is whether your monitor supports AMD FreeSync or NVIDIA G-Sync.
If your monitor supports both technologies, then you can go with any GPU brand. Truth be told, even this decision is more complicated lately, with NVIDIA now certifying an increasing number of FreeSync monitors to variable refresh using NVIDIA cards.
