How are the Linux Radeon drivers these days. Last time I tried (8 years ago) they were awful compared to the NVidia equivalent. But now that I might be able to get a 3 pound ultrabook with decent graphics, I'm willing to put up with a lot more inconvenience .

They're the most reliable and the most performant of the free drivers.

Also, they have pretty good API support: https://mesamatrix.net/

Only Intel is slightly better on that, but their performance is abysmal.

You need a new kernel to support a GPU? What ass-backwards garbage is this? With Windows, it's install a new driver; not update the core of the OS and possibly introduce horrible bugs.

hint: it has something to do with the fact that Windows machines have a reputation for BSoDing regularly, whereas Linux systems have no such reputation.

I've been using Ubuntu desktop for over ten years. My experience is that every now and then it just stops and needs a hard reset. Not as polite as a BSOD.

> Nvidia users are shitty consumers and I don’t even want them in my userbase. Good Lord. I get that the EGLStream vs GBM thing is controversial, but this is childish. How are you supposed to discuss anything with someone who thinks like this.

Not an isolated incident.

Drivers tend to get fixed far faster than Kernels do. I'm speaking from personal experience in my reporting multiple issues with the Linux Kernel. In fact, as I look, the eight I reported years ago are still there, which means the inherent memory vulnerability is still there and Linus (improperly) chose to use ASLR to try to mitigate it instead of fixing it properly in the first place. And you want to make Microsoft…

> Drivers tend to get fixed far faster than Kernels do.

In windows world; but in my experience that's 6-12 months for driver, to 12-24 for kernel.

In linux world, kernels (and drivers) get fixed much much faster, in the order of a couple of months.

"whereas Linux systems have no such reputation." Hah. I've been through kernel panic hell more times than years in my age, and I'm OLD. You must be real new to the Linux world if you think it has a spotless record. In fact, it's still possible to hardlock the kernel all these years after I reported how. Lemme show you how poorly the Kernel handles an encrypted RAMDisk with a couple configured parameters.

> Hah. I've been through kernel panic hell more times than years in my age, and I'm OLD.

So why do you pretend NOT to know at all that the kernel handles/provides drivers? If you're so experienced you should be well aware of that.

If anything Linux Desktops are way less stable than Windows Desktop. Try crashing a graphics driver on Linux and see what happens and compare that to Windows (it restarts without interrupting operation). Most of the Linux schedulers are awful for interactive use as well. I'm forced to use Debian and Scientific Linux installations at work, they are so much worse at basically anything I've experienced both on Windows and macOS it is not even funny.

Well, Windows notably switched to a new graphics driver model in Vista that puts parts of graphics drivers in userland, in order to allow them to crash without taking down the system. But I think that's comparable to what Linux has always been doing with Mesa vs. DRM; not sure what the details look like though.

Ryzen 3 1200, 4 core 3.1/3.4Ghz vs. i5-7400 3.0/3.5Ghz the Ryzen uses .12 watts more at idle and 2.19 watts more at all cores full load. That is a pretty small (<5%) gap.

5% is a lot these days, and that Intel CPU will beat Ryzen clock-for-clock as well. Laptop manufacturers are fighting over every percentage point of gains these days, not trying to move backwards. People want to see all day battery life with reasonably good performance. I like AMD and want more competition for Intel. If you have a use that scales across many cores, AMD is a great value for workstations. Their new ser…

The point is, this comparison is between a 4 core CPU (Ryzen) vs 2/4 cores CPUs (i3 and i5). Vs i5 the difference is less than 1%, vs i3 the difference is 5%.

Every AMD chip contains a likely backdoored system called AMD Secure Processor This is fear mongering to the extreme.

The Intel one has a known technique to disable the ME, the AMD one does not (for the moment).

However, disabling it is not trivial, needing to open your laptop and solding skills, also special equipment to read/write modified firmware.

I experience somewhat frequent GPU crashes when playing Diablo3 under Wine with the integrated i3-4150 GPU, but the graphics stack recovers by itself in about a minute. I can then continue from where I left off, sans the application that crashed with it.
