ZDNET’s key takeaways

  • CuerdOS is a unique, Debian-based Linux distribution.
  • This distro offers blazing-fast performance.
  • You’ll find an interesting collection of preinstalled software.

Every once in a great while, I run into a Linux distribution that I’ve never heard of. Such is the case with CuerdOS.

This Linux distribution of Spanish origin is focused on stability, efficiency, and performance. Based on Debian, CuerdOS is, I’m assuming, a play on the Spanish word cuerdo, which means sane or rational. After using this distribution for a few days, I’d have to say that’s spot on. I downloaded the GNOME flavor of the OS and found the default settings quite sane. 

Instead of the straight-up GNOME desktop, you get a few customizations by way of some GNOME extensions and just the right combination of software. 

Also: The once beloved PCLinuxOS is back – and it’s still a great Windows escape

Now, when you look at the software collection, you could conclude that CuerdOS has something for everyone. There are tools for seasoned users, those with just enough Linux knowledge, and even beginners. 

Would I call CuerdOS the right Linux distribution for new Linux users? Maybe. Would I stake the claim that it’s geared toward power users? Maybe. You see, CuerdOS includes performance tweaks that optimize CPU, GPU, and RAM consumption via a patched kernel. So, yeah, it’s pretty fast.

With all of those maybes tossed around, who is CuerdOS for? That’s an interesting question, one that I’ll get to in a bit.

What I find interesting about CuerdOS

I decided to try the GNOME version of CuerdOS because I’ve ignored GNOME for some time now and thought it was time to go back. You can also select Xfce, Sway, LabWC, and KDE Plasma.

After installing CuerdOS, I logged in and started poking around.

The first thing I noticed was that, thanks to Dash to Dock, the desktop not only looked good, but it was also very user-friendly. 

Next came the collection of preinstalled software, which included the likes of Vivaldi, Timeshift, Yelena Store (GUI app store for both DEB and Flatpak apps), RunCat (an outstanding system monitor), Geany (programming IDE), BleachBit (cleaner), OnlyOffice (office suite), Wasabi Media player, and the Nvidia driver installer.

After pondering this collection, I came to the conclusion that CuerdOS defaults to alternative apps for almost every purpose — and I love that. After a long while of reviewing/using Linux distributions that all ship with the same lineup of software, it’s a breath of fresh air to run into one that goes a less-trodden path.

Seriously, I really appreciate this feature of CuerdOS, and given that all the preinstalled software works very well, you won’t miss anything. But on the off chance you do find CuerdOS lacking, just fire up the Yelena Store, search for what you need, and install it.

When you do open Yelena and install a few pieces of software, you’ll immediately notice the speed of CuerdOS. This thing is fast. One reason is that CuerdOS uses a new Zram configuration that employs the ZSTD algorithm, designed to dramatically improve performance by optimizing memory usage and handling system resources. Trust me when I tell you that it does just that.

I installed CuerdOS as a virtual machine on my System76 Thelio with an AMD Ryzen 9 CPU and 64 GB of RAM. I gave the VM only 4 GB of RAM and 2 CPUs, and CuerdOS performed as well (if not better) than the host OS. 

This distribution performs like one of the many lightweight distros on the market, only it’s not lightweight. That, my friends, is impressive. I opened each of the larger applications on the desktop, and the system resources barely budged.

All was not perfect

I did run into a problem, which took me by surprise. OnlyOffice is installed as the default office suite. When I went to open the app, it refused. I then attempted to open it from the terminal window, only to receive a warning that it couldn’t load the shared libcef.so library.

Also: XeroLinux could be the most beautiful Linux desktop on the market

Here’s what’s odd: libxssl1, the package that includes libcef.so, was already installed. I decided to install OnlyOffice via Flatpak to see if that would resolve the problem with the command:

flatpak install onlyoffice

For some strange reason, that installation failed as well, so I opened the Yelena Store, searched for OnlyOffice, and installed it from there. After that, OnlyOffice ran like a charm.

CuerdOS

All fixed and ready to go.

I then needed to remove the original installation using the Yelena Store (just to keep things clean). 

Other than that one little hiccup, CuerdOS proved to be one heck of a Linux distribution. It’s well-designed, lightning-fast, includes a unique collection of software, and it’s based on Debian. 

Also: How much RAM does Linux really need? My sweet spot after decades of use

What more would you want?

Who is CuerdOS for?

Simply put, if you want an operating system that places a focus on performance, but also has the solidity of the Debian base, and don’t mind using apps that aren’t the traditional fare, CuerdOS is a great option. As the name implies, every choice for this distribution is sane, so you install it and hit the ground running (so long as you resolve the issue with OnlyOffice).

If I’ve piqued your interest, head over to the CuerdOS site, scroll to the download section, select the desktop environment you want, grab an ISO, burn it to a bootable USB drive, install it, and enjoy.

As I’m writing this, NVIDIA is the largest company in the world, with a market cap exceeding $4 trillion. Team Green is now the leader among the Magnificent Seven of the tech world, having surpassed them all in just a few short years.

The company has managed to reach these incredible heights with smart planning and by making the right moves for decades, the latest being the decision to sell shovels during the AI gold rush. Considering the current hardware landscape, there’s simply no reason for NVIDIA to rush a new gaming GPU generation for at least a few years. Here’s why.

Scarcity has become the new normal

Not even Nvidia is powerful enough to overcome market constraints

Global memory shortages have been a reality since late 2025, and they aren’t just affecting RAM and storage manufacturers. Rather, this impacts every company making any product that contains memory or storage—including graphics cards.

Since NVIDIA sells GPU and memory bundles to its partners, which they then solder onto PCBs and add cooling to create full-blown graphics cards, this means that NVIDIA doesn’t just have to battle other tech giants to secure a chunk of TSMC’s limited production capacity to produce its GPU chips. It also has to procure massive amounts of GPU memory, which has never been harder or more expensive to obtain.

While a company as large as NVIDIA certainly has long-term contracts that guarantee stable memory prices, those contracts aren’t going to last forever. The company has likely had to sign new ones, considering the GPU price surge that began at the beginning of 2026, with gaming graphics cards still being overpriced.

With GPU memory costing more than ever, NVIDIA has little reason to rush a new gaming GPU generation, because its gaming earnings are just a drop in the bucket compared to its total earnings.

NVIDIA’s gaming division had been its golden goose for decades, but come 2022, the company’s data center and AI division’s revenue started to balloon dramatically. By the beginning of fiscal year 2023, data center and AI revenue had surpassed that of the gaming division.

In fiscal year 2026 (which began on July 1, 2025, and ends on June 30, 2026), NVIDIA’s gaming revenue has contributed less than 8% of the company’s total earnings so far. On the other hand, the data center division has made almost 90% of NVIDIA’s total revenue in fiscal year 2026. What I’m trying to say is that NVIDIA is no longer a gaming company—it’s all about AI now.

Considering that we’re in the middle of the biggest memory shortage in history, and that its AI GPUs rake in almost ten times the revenue of gaming GPUs, there’s little reason for NVIDIA to funnel exorbitantly priced memory toward gaming GPUs. It’s much more profitable to put every memory chip they can get their hands on into AI GPU racks and continue receiving mountains of cash by selling them to AI behemoths.

The RTX 50 Super GPUs might never get released

A sign of times to come

NVIDIA’s RTX 50 Super series was supposed to increase memory capacity of its most popular gaming GPUs. The 16GB RTX 5080 was to be superseded by a 24GB RTX 5080 Super; the same fate would await the 16GB RTX 5070 Ti, while the 18GB RTX 5070 Super was to replace its 12GB non-Super sibling. But according to recent reports, NVIDIA has put it on ice.

The RTX 50 Super launch had been slated for this year’s CES in January, but after missing the show, it now looks like NVIDIA has delayed the lineup indefinitely. According to a recent report, NVIDIA doesn’t plan to launch a single new gaming GPU in 2026. Worse still, the RTX 60 series, which had been expected to debut sometime in 2027, has also been delayed.

A report by The Information (via Tom’s Hardware) states that NVIDIA had finalized the design and specs of its RTX 50 Super refresh, but the RAM-pocalypse threw a wrench into the works, forcing the company to “deprioritize RTX 50 Super production.” In other words, it’s exactly what I said a few paragraphs ago: selling enterprise GPU racks to AI companies is far more lucrative than selling comparatively cheaper GPUs to gamers, especially now that memory prices have been skyrocketing.

Before putting the RTX 50 series on ice, NVIDIA had already slashed its gaming GPU supply by about a fifth and started prioritizing models with less VRAM, like the 8GB versions of the RTX 5060 and RTX 5060 Ti, so this news isn’t that surprising.

So when can we expect RTX 60 GPUs?

The good news is that the RTX 60 series is definitely in the pipeline, and we will see it sooner or later. The bad news is that its release date is up in the air, and it’s best not to even think about pricing. The word on the street around CES 2026 was that NVIDIA would release the RTX 60 series in mid-2027, give or take a few months. But as of this writing, it’s increasingly likely we won’t see RTX 60 GPUs until 2028.

If you’ve been following the discussion around memory shortages, this won’t be surprising. In late 2025, the prognosis was that we wouldn’t see the end of the RAM-pocalypse until 2027, maybe 2028. But a recent statement by SK Hynix chairman (the company is one of the world’s three largest memory manufacturers) warns that the global memory shortage may last well into 2030.

If that turns out to be true, and if the global AI data center boom doesn’t slow down in the next few years, I wouldn’t be surprised if NVIDIA delays the RTX 60 GPUs as long as possible. There’s a good chance we won’t see them until the second half of 2028, and I wouldn’t be surprised if they miss that window as well if memory supply doesn’t recover by then. Data center GPUs are simply too profitable for NVIDIA to reserve a meaningful portion of memory for gaming graphics cards as long as shortages persist.


At least current-gen gaming GPUs are still a great option for any PC gamer

If there is a silver lining here, it is that current-gen gaming GPUs (NVIDIA RTX 50 and AMD Radeon RX 90) are still more than powerful enough for any current AAA title. Considering that Sony is reportedly delaying the PlayStation 6 and that global PC shipments are projected to see a sharp, double-digit decline in 2026, game developers have little incentive to push requirements beyond what current hardware can handle.

DLSS 5, on the other hand, may be the future of gaming, but no one likes it, and it will take a few years (and likely the arrival of the RTX 60 lineup) for it to mature and become usable on anything that’s not a heckin’ RTX 5090.

If you’re open to buying used GPUs, even last-gen gaming graphics cards offer tons of performance and are able to rein in any AAA game you throw at them. While we likely won’t get a new gaming GPU from NVIDIA for at least a few years, at least the ones we’ve got are great today and will continue to chew through any game for the foreseeable future.
