Radeon™ Memory Visualizer 1.4 introduces Smart Access Memory support

Radeon Memory Visualizer

Starting with version 1.4, Radeon Memory Visualizer (RMV) provides support for Smart Access Memory (SAM). SAM is an AMD feature that can boost the performance of graphically intensive applications by giving the CPU direct access to all available video memory.

When a memory trace is loaded, RMV will detect if SAM was enabled at the time the trace was taken with Radeon Developer Panel (RDP).

Once the trace has been loaded into RMV, you can create a snapshot for any point on the timeline and then select the snapshot by double-clicking it in the table.  The Local heap section of the Heap overview pane displays a message indicating whether SAM was enabled or not. The Invisible heap is not shown for traces taken with SAM enabled since all memory is visible to the CPU.

Radeon™ Memory Visualizer (RMV) is a tool to allow you to gain a deep understanding of how your application uses memory for graphics resources.

The image below is a screenshot of RMV’s Heap overview pane with a memory trace taken with SAM enabled.

Prior releases of RMV are unable to detect when SAM is enabled and display some allocations as associated with the Invisible heap.  Below is a screenshot from the previous RMV release.

In addition to supporting SAM, RMV 1.4 adds support for LPDDR4/5 and DDR5 memory, as well as bug fixes to improve stability and overall user experience.
