Working at IBM, opinions here are my own

[clamchowder @lamchester]

@Sosowski You can have a x86-64 machine that isn't PC-compatible and won't run mainstream Linux out of the box (look at consoles like the PS4). You can run a modified kernel tho

And you can run Linux on many Arm devices, you just need devicetree and/or a modified kernel

[clamchowder @lamchester]

@TDevilfish They could certainly do that, I just think it's a harder and less straightforward route. Don't get me wrong, Skymont is amazing for what it does. But it's not a P-Core

[clamchowder @lamchester]

Sharing some thoughts on Intel's possible unified core project. Basically, I think the easiest route is a Zen 4c/5c style shrink of their P-Core. But of course, Intel has more options than that

@purkkaviritys @lauriewired Also, speculative execution vulnerabilities only matter when you're executing untrustred code. If you control all the code that runs on your machines, which some corporations do depending on the use case, you don't need mitigations.

[clamchowder @lamchester]

@lauriewired It's still a lot. Newer CPUs have much more reordering capacity and core width than Haswell, and it's not just about IPC. They clock much higher than Haswell did too

Sharing another piece I wrote last year, comparing hardware AV1 encoding on Intel's Arc B580 and AMD's Hawk Point, at https://t.co/iG2o6nvORf
Should be a good test of image handling on the site, with sliders for quality comparisons

[clamchowder @lamchester]

@zytkownik @lemire That's an option, but most Linux distros distribute binaries, not source. Shipping binaries reduces install time (compile times can be very long for large projects)

[clamchowder @lamchester]

@BorisTheBlade42 I might look into that eventually, though optimizing mobile is going to be pretty far down my priority list. A lot of what I intend to do probably won't work well on mobile anyway

[clamchowder @lamchester]

Sharing a piece I wrote a while ago on Zen 1, mostly to test site design with plenty of pagination, tables, and captioned images. It's a pretty complete article by itself though, and I hope yall find it a fun read: https://t.co/QjGJ4b35Mz

[clamchowder @lamchester]

@lauriewired GHz-normalized scores are a red flag. I'd hold off until they get to large scale production and we see what kind of clock speeds they can reach.

IPC may also not scale with clock speed because DRAM accesses take more clock cycles if your cycle time is shorter

Posting another fun article on Chips and Cheese, this time on chipset latency: https://t.co/wBXHBScyib

[clamchowder @lamchester]

Testing write bandwidth on GPUs: https://t.co/6nHW1YUhFi
Intel's B580 does a lot of really interesting things, including apparently, doing write-back L1 caching in Vulkan. Nearly everyone else has L2 as the first write-back level

[clamchowder @lamchester]

@88_vnd @joni_askola That's pretty much Putin no? Bleeding Russia dry and squandering national resources in a pointless war, all while sitting in palaces, detached from reality

[clamchowder @lamchester]

Using pointer dereferences to test GPU cache latency with less overhead, without assembly: https://t.co/Zyiutcolp4

[clamchowder @lamchester]

@nepnep1111_ @CapFrameX @bs_blackscout Which anticheat does this and what's their justification, other than perhaps outdated winring0 driver?

Anticheats is part of why I stay away from the big-name multiplayer games now. Client-side sniffing is the wrong way to approach the issue anyway.

@OlenaRohoza This happened last year in 2024: https://t.co/Zr6exikDhS

It's not a recent event, but still serves to show the cost of Russia's war. Congrats to Ukraine, and good to see them continuing to fight off Russia's invasion.

@Conserv_a_Tude @RJR1225 @doggintrump We haven't arrived at where Germany and Italy were in 1939. But Trump is starting on the path of demanding absolute conformity, and is setting up to abuse the police/military to achieve that goal. That's the concerning part.

[clamchowder @lamchester]

@BroThriving @mazzenilsson @sentdefender Imagine calling someone uneducated without presenting a well-supported rebuttal. Or just, no rebuttal at all.

[clamchowder @lamchester]

@OOregenes @molly0xFFF I would be surprised if they had any policies or quality standards worth paying attention to
