Content creation professionals will appreciate how the Radeon™ VII 16GB of VRAM capacity frees them to manipulate exceptionally high-quality assets, like 4K and 8K video, while using their traditional tool chains.
Of course, tools that measure VRAM allocation don't always tell the whole story. Applications sometimes fail to let go of bits they're no longer actively using, so exceeding your video card's indicated VRAM usage doesn't always lead to obvious complications. When a system does run up against a VRAM limit in practice, though, the result can be severe slowdowns or even instability.
Here's one example of what happens when a game overruns the video card's VRAM capacity. Below is a plot of the frame times over time while walking through the Montana forest in Far Cry 5.
capacity. The HBCC then manages the migration of data between local VRAM and system memory, making sure the right bits are in VRAM as needed.
Here's a look at how the Radeon RX Vega 64 performs with and without the HBCC enabled.
