New Linux CRAM Technology Could Boost Memory Performance, But Steam Deck Users Shouldn’t Expect an Upgrade Yet
A new Linux memory technology is generating excitement among PC gaming and handheld gaming fans, especially those hoping for future Steam Deck performance improvements. Known as CRAM, short for Compressed RAM, the technology is designed to make system memory more efficient by storing compressed data directly in RAM while still allowing extremely fast access.
For devices with limited memory, that sounds like a major breakthrough. The Steam Deck, for example, includes 16 GB of shared memory used by both the CPU and GPU. In theory, a smarter way to use RAM could help memory-heavy games run more smoothly, reduce pressure on system resources, or even improve loading behavior. However, while CRAM looks promising on paper, current Steam Deck owners should not expect a simple software update to unlock these benefits.
CRAM is being developed by engineers at Meta and was recently presented at the Linux Plumbers Conference in Prague. The core concept is easy to understand: instead of storing everything in RAM in its normal uncompressed form, CRAM compresses data so that more information can fit into the same amount of physical memory.
Linux already has memory compression technologies such as ZRAM and Zswap, but CRAM takes a different approach. With older methods, compressed data often has to be decompressed and copied back into standard system memory before it can be used. CRAM is designed to avoid that extra step. In the version presented, compressed data can be read directly thanks to specialized memory hardware that handles decompression automatically.
That hardware support is the key detail. It is also the reason why the current Steam Deck cannot simply take advantage of CRAM through a SteamOS update.
Early benchmarks show why people are paying attention. In read-only memory tests, CRAM reportedly performs close to regular uncompressed RAM. Compared with ZRAM, it was up to 452 times faster in certain test conditions. That is a huge difference, but the picture changes when write operations are added.
When the workload includes 20% write operations, CRAM still remains ahead, but the advantage drops to around 5.4 times faster. As write activity increases, the performance gap becomes smaller. This matters because real-world games and applications do not only read data from memory; they constantly read and write in different patterns.
That means the impressive benchmark numbers should be viewed carefully. These are specialized memory tests, not direct gaming benchmarks. Faster memory access in a controlled test does not automatically mean higher frame rates, smoother gameplay, or shorter loading screens in actual PC games.
For Steam Deck fans, CRAM is interesting because Valve’s handheld gaming PC runs on Linux-based SteamOS. Any major Linux memory improvement naturally raises the question of whether it could help the Steam Deck. Since the handheld uses shared memory for graphics and processing, more efficient RAM usage could theoretically benefit demanding games that push the device close to its limits.
Some users are already speculating that CRAM could eventually help reduce memory bottlenecks, improve loading times, or allow games to run more efficiently on hardware with limited RAM. However, there is currently no clear evidence that CRAM would deliver major gaming improvements on the existing Steam Deck.
The biggest obstacle is hardware compatibility. The CRAM implementation shown so far depends on specialized memory hardware capable of decompressing data as it is read. The current Steam Deck does not include that hardware. Because of this, CRAM cannot be enabled in its full form through a normal operating system update.
That does not mean the technology has no future in handheld gaming. If CRAM or a similar compressed memory system becomes widely adopted, it could become a feature in future gaming devices. A next-generation Steam Deck could potentially include hardware designed to support this type of memory compression, assuming the technology matures and proves useful outside of synthetic benchmarks.
Still, it is worth keeping expectations realistic. In many modern games, RAM capacity is not always the main performance limit. The CPU, GPU, storage speed, power limits, and thermal restrictions often play a bigger role, especially in compact handheld gaming PCs. Even if CRAM allowed more efficient memory usage, it might not produce dramatic frame rate improvements unless a game is specifically limited by memory performance or capacity.
For now, CRAM is best seen as an exciting Linux technology with long-term potential rather than an immediate Steam Deck upgrade. It could become important for servers, workstations, laptops, and future handheld gaming systems, especially as software continues to demand more memory. But current Steam Deck owners should not expect CRAM to suddenly transform performance through SteamOS.
The bottom line is simple: CRAM shows that compressed memory technology is evolving quickly, and its early benchmark results are impressive. However, because it relies on specialized hardware, the current Steam Deck cannot benefit from it in the way some users might hope. The real opportunity may come later, possibly with future Linux gaming hardware designed from the start to support advanced compressed RAM features.
