Meanwhile, the Radeon VII with 16GB virtually eliminates stutter as measured by this metric. The HBCC greatly reduces slowdowns, especially in the later test runs, once the HBCC’s caching algorithm understands how the application is using its data. The higher that number, the rougher the animation. This metric adds up all the time across our test run where the delays between frames are more than 50 milliseconds. We’re looking at “time spent beyond 50 ms,” an indicator of the amount of stutter. In fact, the results below from multiple test runs tell an even more interesting story. iiiĪs you can see, turning on the HBCC reduces the number and severity of the stutters in this scenario. Here’s a look at how the Radeon RX Vega 64 performs with and without the HBCC enabled. The HBCC then manages the migration of data between local VRAM and system memory, making sure the right bits are in VRAM as needed. The HBCC reserves a portion of system memory for use by the GPU, effectively extending the VRAM capacity.

The “Vega” architecture has a feature meant to deal with situations like this one: the High Bandwidth Cache Controller (HBCC). Radeon RX Vega owners may be wondering how their cards fit into this picture. That’s the case for higher VRAM capacity in a nutshell: when you need it, you’ll really wish you had it. This difference may not be obvious when looking at an FPS average, but you’ll definitely notice it while playing a game. With its larger memory capacity, the Radeon VII maintains fluid animation, while the competition cannot. While playing, you’ll perceive these spikes as slowdowns and stuttering. The 8GB card suffers from intermittent spikes to very high frame times. Below is a plot of the frame times over time while walking through the Montana forest in Far Cry 5. Here’s one example of what happens when a game overruns the video card’s VRAM capacity. When a system does run up against a VRAM limit in practice, though, the result can be severe slowdowns or even instability.

Applications sometimes fail to let go of bits they’re no longer actively using, so indicated usage exceeding your video card’s VRAM capacity doesn’t always lead to obvious complications. Of course, tools that measure VRAM allocation don’t always tell the whole story. We expect this list to grow as new titles are released. As you probably know, this is an especially busy season for the game industry. Here’s a look at the VRAM allocation we measured while running some popular games.

Each of these things can improve the gaming experience-and together, they can look absolutely glorious in motion-but they all require larger video memory capacity.Īs a result, today’s games can exceed 8GB of VRAM usage at their highest quality settings. They also use some nifty tricks to maintain steady frame rates, like adaptive quality and dynamic resolution scaling. The latest games include ultra-high-quality art assets that stand up to scrutiny on high-PPI monitors, and they support deeper color formats for high-dynamic range displays. Meanwhile, game developers are always pushing the boundaries with breathtaking visuals and huge, open worlds to explore. Creative professionals will know their data sets and understand where Radeon™ VII 16GB of VRAM can improve their workflows. Other content formats are growing their fidelity in response. Video formats continue to evolve with support for higher pixel counts, HDR, wide color gamuts, and high frame rates. This new GPU is meant to handle some of the most demanding new workloads that gamers and content creators can throw at it.Ĭontent creation professionals will appreciate how the Radeon™ VII's 16GB of VRAM capacity frees them to manipulate exceptionally high-quality assets, like 4K and 8K video, while using their traditional tool chains.įor a very common example, here’s a look at measured VRAM usage in Adobe Premiere while encoding 4K and 8K video on the Radeon VII.

That’s why we built the Radeon™ VII graphics card with a remarkable HBM2 memory configuration with 16 GB of VRAM capacity and one terabyte per second of bandwidth. Although hardware consistently grows more capable over time, applications are always asking for more.
