In computer science, a memory leak is a type of resource leak that occurs when a computer program incorrectly manages memory allocations [1] in a way that memory which is no longer needed is not released. A memory leak may also happen when an object is stored in memory but cannot be accessed by the running code (i.e. unreachable memory). [2]
In effect, physical main memory becomes a cache for virtual memory, which is in general stored on disk in memory pages. Programs are allocated a certain number of pages as needed by the operating system. Active memory pages exist in both RAM and on disk. Inactive pages are removed from the cache and written to disk when the main memory becomes ...
Out of memory screen display on system running Debian 12 (Linux kernel 6.1.0-28) Out of memory (OOM) is an often undesired state of computer operation where no additional memory can be allocated for use by programs or the operating system. Such a system will be unable to load any additional programs, and since many programs may load additional ...

R520's memory bus differs with its central controller (arbiter) that connects to the "memory clients". Around the chip are two 256-bit ring buses running at the same speed as the DRAM chips, but in opposite directions to reduce latency. Along these ring buses are four "stop" points where data exits the ring and goes into or out of the memory chips.
Software distributors use executable compression for a variety of reasons, primarily to reduce the secondary storage requirements of their software; as executable compressors are specifically designed to compress executable code, they often achieve better compression ratio than standard data compression facilities such as gzip, zip or bzip2 [citation needed].
the client calls directly cause rendering of graphics objects to the display, or in which; the data to describe rendering primitives is inserted frame by frame directly from the client into a command list (in the case of immediate mode primitive rendering), without the use of extensive indirection – thus immediate – to retained resources.

The Navi GPUs are the first AMD GPUs to use the new RDNA architecture, [6] whose compute units have been redesigned to improve efficiency and instructions per clock (IPC). It features a multi-level cache hierarchy, which offers higher performance, lower latency, and less power consumption compared to the previous series.
