What is a GPU?
The Basics of GPU Architecture
A GPU, or Graphics Processing Unit, is a specialized type of processor designed to handle the complex mathematical calculations required for rendering images and graphics. Unlike a CPU, or Central Processing Unit, which is designed to handle a wide range of tasks, a GPU is optimized specifically for graphics processing.
One of the key differences between a CPU and a GPU is the way they handle calculations. A CPU uses a serial processing architecture, meaning that it processes one instruction at a time, in order. In contrast, a GPU uses a parallel processing architecture, meaning that it can process multiple instructions simultaneously. This allows a GPU to perform many calculations at once, making it much faster than a CPU for tasks that can take advantage of this parallel processing.
Another key difference between CPUs and GPUs is the way they handle data. A CPU uses a single instruction, multiple data (SIMD) architecture, which means that it processes one instruction on multiple data elements at the same time. In contrast, a GPU uses a single instruction, multiple threads (SIMT) architecture, which means that it processes multiple threads of data simultaneously using the same instruction. This allows a GPU to handle much larger amounts of data than a CPU, making it ideal for tasks that require processing large amounts of data.
Overall, the basics of GPU architecture involve a specialized design that allows for fast and efficient processing of complex mathematical calculations, making it an ideal choice for tasks that require high-performance graphics processing.

Floating-point arithmetic is used to perform mathematical operations on decimal numbers, which are commonly used in scientific and engineering applications. GPUs are designed to perform floating-point calculations much faster than traditional CPUs, making them ideal for tasks such as simulating complex physical systems or training machine learning models.
In addition to their floating-point performance, GPUs also support a number of programming frameworks that make it easier to develop parallel applications. CUDA (Compute Unified Device Architecture) is a popular framework developed by NVIDIA that allows developers to write programs that can be executed on GPUs. Similarly, OpenCL (Open Computing Language) is an open standard for programming GPUs and other accelerators.
Another important feature of modern GPUs is their support for specialized hardware such as Tensor Core and FPGA (Field-Programmable Gate Array). Tensor Core is a dedicated hardware accelerator for deep learning workloads, designed to speed up tasks such as image recognition and natural language processing. FPGA, on the other hand, is a programmable chip that can be used to implement custom hardware accelerators for a wide range of applications.
Overall, the power of GPUs lies in their ability to perform complex calculations at high speeds, making them an essential tool for many modern computing tasks. Whether you’re working in scientific research, machine learning, or simply need to render high-quality graphics, a GPU can help you get the job done faster and more efficiently.

Memory and VRAM
The amount of memory and VRAM (Video Random Access Memory) a GPU has is also an important factor to consider. VRAM is a type of memory that is specifically designed for handling graphical data, such as textures, shaders, and framebuffers. It is used to store the data that is being processed by the GPU at any given time.
The amount of VRAM on a GPU is important because it determines how much graphical data the GPU can handle at once. If a GPU has too little VRAM, it may be unable to handle large or complex scenes, resulting in slow performance or crashes. On the other hand, if a GPU has too much VRAM, it may be more expensive and unnecessary for your needs.
Power Consumption and Thermal Throttling
Power consumption and thermal throttling are also important factors to consider when choosing a GPU. A GPU that consumes too much power may be more expensive to run and generate more heat, which can reduce its lifespan and lead to performance issues.
Thermal throttling is the process of reducing a GPU’s clock speed and performance when it becomes too hot. This is done to prevent the GPU from overheating and failing, which can result in irreparable damage. If a GPU’s thermal throttling is too aggressive, it may limit its performance and cause it to run at lower speeds than it is capable of.
