You can plug 4K displays on the RPI4 and it is far from being the most powerful SBC out there

it can only do so from local storage afaik

Local storage of screen? 🤔

Night_H4nter 2022-09-02 13:33:19
ffs

who the fuck downloads the porn

of what fucking screen?

Night_H4nter 2022-09-02 13:33:31
of rpi
Night_H4nter 2022-09-02 13:33:59
i mean web browser video playback sucks really bad on those sbcs
qontinuum 2022-09-02 13:34:00
I am talking about connecting a 4K screen why the fuck do you talk about downloading

But yeah, GPU is often an old Mali shit

T860 handles openmw pretty well. And video is absolutely fine on RK3399

Night_H4nter 2022-09-02 13:22:39
you can’t remove ime lol

On some really older models you could

lanciagreggori 2022-09-02 15:28:25
But yeah basically impossible on modern systems

I have one but never tried the GPU

lanciagreggori 2022-09-02 15:30:04
Also please don’t use older thinkpads to get away from IME, you’re basically asking to get fucked

are there any laptops or desktops out there that have IME removed from their CPUs and have AMD GPUs?

Intel core duo

But no chance with newer iirc

lanciagreggori 2022-09-02 15:34:54
Older thinkpads most likely have stopped receiving microcode updates a long time ago, so they’re vulnerable to almost every intel CPU security bug under the sun especially meltdown or spectere

I also heard that the older CPUs on those thinkpads also lack many security features modern CPUs come with

The older ones?

lanciagreggori 2022-09-02 15:36:01
Because every modern one isn’t

Your best bet is to ditch x86 entirely and goto something like ARM or PowerPC

Are they even vulnerable to those vulnerabilities?

Modern core 2 duo?

Are we 15 years back in the past?

Team -ffast-math and mitigations=off. Going nowhere faaassttt

idk about fastmath

It sacrifices some precision to improve performances

To meltdown and spectere, most probably

Night_H4nter 2022-09-02 16:08:27
so, bring even more bugs?
lanciagreggori 2022-09-02 16:08:44

Yeah I thought those hold CPUs didn’t have Hyperthreading but they do

Night_H4nter 2022-09-02 16:09:33
they must have

Yup, it is just even worst concerning performances
