Linus Torvalds Continues Using A Radeon RX 580 Graphics Card, Back On An Intel Laptop

([Radeon] 6 Hours Ago Radeon RX 580)


The AMD Radeon RX 480 / RX 580 "Polaris" graphics cards remain very popular on the Steam Survey and among enthusiasts/desktop users at large even though they are nearly a decade old. The nine year old Polaris graphics cards have aged well in the marketplace and are an affordable choice. For Linux users they continue enjoying strong open-source driver support. It turns out Linux creator Linus Torvalds himself is still relying on an AMD Radeon RX 580 with one of his main systems.

Due to bisecting and working through a regression that popped up during the Linux 6.17 merge window this week, Linus Torvalds' main display went black when booting into the new kernel code. It offered a glimpse at his current system configuration used by Torvalds in the development of the Linux kernel.

A few years ago [1]Linus Torvalds switched to using AMD Ryzen Threadripper after 15 years of using Intel CPUs for his main system. Threadripper continues serving him well for quick Linux kernel builds - no surprise there, even the newly-released [2]Threadripper 9970X and 9980X deliver some crazy fast Linux kernel build times . With not being a gamer himself, Linus Torvalds continues getting by in 2025 with the AMD Radeon RX 580 "Polaris" graphics card.

While [3]working through a DRM regression for Linux 6.17, he noted he is currently using a Radeon RX 580 with ASUS ProArt 5K display on his speedy system for kernel builds. Or as [4]he called it the " same old boring Radeon RX 580. "

Running a 5K display with a Polaris GPU would be too much for gaming, but paired with Display Stream Compression (DSC) is suitable for his desktop and kernel development workflows. It actually was due to an AMDGPU Display Stream Compression commit that led to his regression in Linux 6.17 that is now being sorted through. For now he reverted the problematic patch to continue on with managing the Linux 6.17 merge window.

While not related to the regression noted, it turns out Linus Torvalds is back to using an unspecified Intel-powered laptop. Shortly after the arrival of Apple Silicon ARM-based laptops, [5]Torvalds was using an Apple MacBook M1 . But it turns out he's back to using an Intel laptop. He didn't note a particular laptop model or CPU besides simply noting it's using "Intel i915" graphics.

Besides Threadripper + Polaris for quick kernel builds and an Intel laptop, Linus Torvalds is also known to recently use [6]an Ampere Altra workstation for ARM64 Linux kernel testing.

Linux Ported to Homer Simpson's Brain

SPRINGFIELD -- Slashdot recently reported on Homer Simpson's brain "upgrade"
to an Intel CPU. Intel hails the CPU transplant as the "World's Greatest
Technological Achievement". Intel originally planned to install Microsoft
Windows CE (Cerebrum Enhanced) on Homer's new PentiumBrain II processor.
However, due to delays in releasing Windows CE, Intel decided to install
DebianBrain Linux, the new Linux port for brains.

Computer industry pundits applaud the last minute switch from Windows to
Linux. One said, "I was a bit concerned for Homer. With Windows CE, I could
easily imagine Homer slipping into an infinite loop: "General Protection
Fault. D'oh! D'oh! D'oh! D'oh..." Or, at the worst, the Blue Screen of
Death could have become much more than a joke."

Some pundits are more concerned about the quality of the Intel CPU. "Linux
is certainly an improvement over Windows. But since it's running on a
PentiumBrain chip, all bets are off. What if the chip miscalculates the core
temperature of the power plant where Homer works? I can just imagine the
story on the evening news: 'Springfield was obliterated into countless
subatomic particles yesterday because Homer J. Simpson, power plant
button-pusher, accidentally set the core temperature to 149.992322340948290
instead of 150...' If anything, an Alpha chip running Linux should have been
used for Homer's new brain."
