DirectX 12 Work Diagrams Make ready For Fate of Designs Delivering, AMD Demo Shows Tremendous Improvement In Delivering Times Utilizing Radeon RX 7900 XTX GPU
In a past post, we made sense of how DirectX 12 Programming interface’s most recent component known as Work Charts will empower full GPU independence, lessening how much work that is ordinarily finished on the computer processor and moving it directly to the GPU for quicker delivering and generally speaking quicker execution in games and applications.
At GDC 2024, AMD displayed an early demo of Work Diagrams running simultaneously with Lattice Hubs which extends the DirectX 12 component.
What Cross section Hubs will do is that they interaction draw calls while the remainder of the chart is executing.
The demo features the entire scene (short the UI and Skybox) being delivered on a solitary work diagram dispatch.
The demo was run on an AMD Radeon RX 7900 XTX “RDNA 3” GPU which completely upholds DirectX 12 Work Diagrams and Cross section Shaders, permitting it to run a lot quicker ExectureIndirect, the customary method of chart execution and delivering a scene.
The method was 1.64x more slow than Work Diagrams which shows the benefit of the new element. AMD likewise shared a few fascinating measurements about its new demo which highlights:

6600 draw calls per frame (after coalescing):
- After optimizing the rendering process, the system can handle up to 6600 draw calls per frame. Draw calls are commands sent to the GPU to render an object or part of a scene. Coalescing refers to the process of combining multiple draw calls into a single, more efficient call, thereby reducing overhead and improving performance.
13 million triangles per frame:
- Each frame can accommodate rendering of up to 13 million triangles. Triangles are basic geometric shapes used to construct 3D models in computer graphics. Rendering a large number of triangles per frame allows for more detailed and complex scenes to be displayed.
200,000 work items passing through the graph:
- Within the system’s processing pipeline, there are 200,000 individual tasks or operations, referred to as work items, that traverse through a graph structure. This graph likely represents the flow of data or operations within a computational or rendering process.
37 nodes and 9 draw nodes:
- The processing graph consists of 37 nodes, which are individual components or stages in the computational pipeline. Additionally, there are 9 draw nodes specifically responsible for initiating draw calls to render objects onto the screen. Nodes in a processing graph typically represent different stages of computation or data manipulation.
Less than 200 MiB of work graph backing store memory:
- The memory allocated for storing the work graph data, known as the backing store memory, is limited to less than 200 megabytes (MiB). This memory is used to store the structure and data associated with the processing graph, including nodes, connections, and work items. Keeping memory usage within this threshold helps optimize performance and resource utilization.
- Work Diagrams will be the following significant expansion to the DirectX 12 Programming interface and is supposed to be accessible with Cross section Hubs in the not so distant future. NVIDIA and Intel are additionally locally available the Work Charts trend so expect improvements from them too on the innovation as it builds up some decent momentum
