![]() VRMs can get very hot and sometimes even hotter than GPU and they require good cooling to keep the graphics card from shutting down. Some graphics cards have a higher number of VRMs compared to others. The number of Voltage Regulators on a graphics card varies from card to card. VRM is also called a Processor Power Module (PPM) or simply Voltage Regulator. Along with GPU and VRAM, VRM is also one of the most important components of a graphics card. Generally, it converts 12V to around 1V to 1.5V (approx) which is normally the voltage level at which GPU operates. VRM converts higher voltage from power supply to lower voltage levels for use in GPU. VRM or Voltage Regulator Module is the main circuitry that powers the GPU. You can read the complete comparison of all these graphics card video memories by going through the link given below. HBM memory is faster, requires lesser space on PCB and has lower power consumption compared to GDDR5 memory. Radeon R9 Fury X and Radeon Pro use HBM memory. HBM (High Bandwidth Memory) and HBM2 are the most advanced graphics card memories for gaming and VR (Virtual Reality) and are used in high-end graphics cards only. Nvidia Titan X, GeForce GTX 1080 and GeForce GTX 1080 Ti uses GDDR5X memory. GDDR5X is almost twice as fast as GDDR5 and is used in a few top-end graphics cards from Nvidia. GDDR5 is the most popular and commonly used VRAM that is used in the budget, mid-range, and high-end graphics cards. DDR3 is the oldest and slowest of all and is used mainly in entry-level graphics cards. Graphics card memory includes DDR3, GDDR5, GDDR5X, HBM, and HBM2 RAM. There are various types of Video RAM available for graphics card depending on the speed and bandwidth they offer. It is to be noted that memory alone cannot increase the performance in games because if your GPU is weak then you will never have greater performance no matter how fast the RAM is. Faster memory can really increase the graphics card performance to a certain level. ![]() VRAM or Video RAM or Video Memory is the place where all the graphics data and game textures are stored for processing by the GPU. This is the second most important component of a graphics card. CUDA Cores vs Stream Processors Compared.Pascal vs Polaris GPU Architecture Compared.Generally newer the GPU architecture, the better is the performance of the graphics card, and also it has lower power consumption compared to the older architectures. Nvidia calls them CUDA Cores and AMD calls them Stream Processors but technically they are different from each other because of different GPU architectures involved. The functionality of these processor cores is governed by GPU architecture. There are hundreds and thousands of cores in GPU for parallel processing and multi-tasking. Also, different GPU manufacturers have their own GPU architecture and layout.įor example, currently, the latest GPU architecture from Nvidia is Pascal and from AMD it is Polaris. Different GPU series have different GPU architecture. The working of GPU is governed by its architecture which is known as GPU architecture. Generally, most of the graphics card comes with only one GPU but there are few dual GPU graphics cards also. It is also known as Graphics Processor and does all the processing in your graphics card. GPU or Graphics Processing Unit is the main component and heart of the graphics card. Here are the major components that are present in all graphics cards. Technical Terms Associated with Graphics Cards.
