As the scaling of DRAM density slows physically, a promising solution is to scale it up logically via hardware memory compression, which enhances CPU’s memory controller (MC) to squeeze more data into DRAM. Hardware-compressed memory decouples OS-manage
The demand for memory is ever increasing. Many prior works have explored hardware memory compression to increase effective memory capacity. However, prior works compress and pack/migrate data at a small – memory block-level – granularity; this introduces an additional block-level translation after ...
"Comparing our memory to other system's memory actually isn't equivalent," Apple vice president of worldwide product marketing Bob Borchers said in anew interview, "because of the fact that we have such an efficient use of memory, and we use memory compression, and we have a unified memory...
The Compression Attached Memory Module (CAMM) standard has been adopted by the laptop memory segment, and manufacturers are believed to be transferring technological innovations to desktop form factors. Upcoming 64 GB DDR5 modules offer twice the capacity over the best previous-gen solutions. The ...

I suspect it is effective memory compression (and plenty of spare CPU power to do it), high speed SSDs, high bandwidth (and no need to use memory bandwidth to copy to/from GPU memory) among other things. I'm not going to go so far as to say 8 GB on M s...
Windows also uses file compression in NTFS, as does Linux' Btrfs, but in general these incur a performance penalty, making the primary benefit increased disk space at the cost of performance.Compressing the contents of volatile system memory, rather than disk storage, has remained e...
I saw some misinformation on reddit floating around that you can increase performance by grossly increasing the GC frame value. Iirc, they basically had garbage collection wait 30 minutes or something before performing any clean up. Bad idea. Not saying you followed that particular advice, just ...
CPU-Z benchmark has a typical mix of memory accesses. Branches are less common in CPU-Z than in games, compression, and Cinebench 2024. Performance Overview CPU-Z is a moderate IPC benchmark. All of the CPUs here achieve a bit under half their core width. Bulldozer is an exception and...
Virtual Memory is an idea originated in the operating systems world,50 years ago. It is probably one of the few non trivial OS ideas that many non tech people are aware of, in some way: theswap fileis a famous object, and most Windows power users more or less understand how it works...
