Major GPU Designers and their Flagship GPU Families Powering Modern Compute Workloads

What is a GPU?

A GPU (Graphics Processing Unit) is a specialized processor designed to handle tasks that require numerous small calculations simultaneously, particularly in graphics, image processing, video, and AI workloads.

Unlike a CPU (which has a few powerful cores optimized for sequential tasks),

A GPU has hundreds to thousands of smaller cores designed for parallel processing.

That makes GPUs ideal for:

• gaming graphics & rendering
• video editing & 3D modeling
• scientific computing & simulations
• machine learning & AI training

Key Components of a GPU

Here are the most important parts and what they do:

GPU Cores (CUDA / Stream / XMX units)

• NVIDIA – CUDA / Tensor cores
• AMD – Stream processors / Matrix cores
• Intel – Xe / XMX units

VRAM (Graphics Memory)

• VRAM (Graphics Memory) is the dedicated memory on a GPU that stores textures, graphics assets, AI model weights, frame buffers, and compute data so the GPU can access them quickly during rendering or processing tasks.
• Different types of VRAM are used depending on the workload: GDDR6 and GDDR6X are commonly found in gaming and workstation GPUs, while high-bandwidth memory types such as HBM2 and HBM3 are typically used in data-center and AI GPUs to support extremely large and demanding compute operations.
• Having more VRAM generally improves performance in scenarios like 4K gaming, professional video editing, AI model training, and working with large datasets, because it allows more data to be stored and processed directly on the GPU without frequent data transfers.

Memory Bandwidth

Determines how fast data moves between GPU & VRAM. Higher bandwidth = better for:

• high-resolution graphics
• AI & deep learning
• scientific computing
• HBM GPUs have extremely high bandwidth.
