What is graphics memory, and what does it do? GDDR5 allows very high data transfer rates – the theoretical maximum being 32,000Mb/s per pin, although in reality it will likely be slower due to interference from other components on the card. Unlike DDR-SDRAM, GDDR5 is designed specifically for use in graphics cards. This is the fastest memory on a graphics card and can be found on both integrated and discrete models. It tends to have a longer refresh rate than DRAM, so it can be used as an intermediate “permanent” storage by the graphics processing unit (GPU). It is primarily used as the frame buffer – the area where pixel data for an entire frame is stored before it’s rendered. This type of memory is larger and slower than DRAM, but has far greater storage capacity. The amount of DRAM on a graphics card can range from a few megabytes on older cards to up to 12GB on some high-end gaming cards. DRAM is what’s called “dynamic” because its contents are dynamically refreshed every few milliseconds (the refresh rate varies depending on the monitor). It has low latency and is tightly integrated into the graphics rendering pipeline. It is used to store information that changes frequently, such as pixel data. This type of memory is the smallest on the card. These three different types of memory have different purposes, despite being used to store pixels that create your display image. double data rate synchronous DRAM (DDR-SDRAM) and.There are three main types of memory on a graphics card: different types of graphics memory on a graphics card
DOES OWC MEMORY WORK WITH MAC MEMORY UPGRADE
Like any other type of computer hardware, there are different speeds and types of RAM available, however it’s important to pay attention to memory type when shopping for a graphics card upgrade because you’ll probably want a couple different sticks in your system for optimal performance.įor example, an Nvidia GeForce 660 with 2GB of dedicated video RAM (DVR) will display its available memory as 2048MB.Ĭheck out the helping guide at 3 Pin Vs 4 Pin Fan Cables. Total available graphics memory is the maximum amount of RAM that your graphics card can access to do its job.
