I stumbled upon an interesting blog today while searching for an image of the Silicon Graphics 3D cube logo. Named "Abort Retry Fail" by Bradford Morgan White, the blog's articles document computer history. I eventually wound up reading three of them.

#1 "The Rise and Fall of Silicon Graphics"

#Turbostat Utility Bumps 1024 #CPU Core Limit To 8192 Cores After #HPE Breaches It With a 1152 Core unnamed system.
We currently aren't aware of any server CPU configurations that can exceed this limit (in terms of physical cores), so this may be a custom or next-generation solution from #Intel or #AMD. The utility currently only supports #x86 processors, which seemingly rules out an Arm system from causing the issue.

ITs History!
The #Atari 1200XL was a 8bit #homecomputer running a #MOS 6502 #CPU at 1.79 MHz. When this beautiful machine was launched in 1983 with 64Kb RAM the price was under thousand dollars, but... https://youtu.be/JyA5tA5mmYY

$omehow, in the #8bitwar the #C64 was much more popular even when specs been almost the same. The difference in #BASIC language was less significant for the success. Most likely that competition was won by #Commodore because Jack Tramiel took the advice of his grandfather so serious.

It’s not just clock speed: Here’s what makes one CPU better than another

“When you’re comparing two of the best CPUs, the first spec that comes to mind is clock speed. It quite literally represents how fast the CPU can churn through clock cycles, and naturally, you’d assume a higher clock speed means higher performance. ...continues

Looking forward to learning more about this libre-licensed RISC-V SoC with Kazan GPU and VPU.

crowdsupply.com/libre-risc-v/m

I'm really curious how these types of chips are prototyped. I know we can simulate a few hundred thousand logical operations with an FPGA, but is that even close to simulating a powerful chip of this size?

Pooter running again now; system pkgs updates done, data copied back from Lappy to Pooter, so far all seems ok... but i remain apprehensive til further notice.

Vendor has, i feel, stiffed me a bit. The unit i ordered was accompanied online by a picture unambiguously showing it was a 0.6 amp job. The one that was delivered today is a 0.2 amp job. The original one, now dodgy, is 0.28 amp, so not only did i not get what i wanted, it's not even as powerful as my original. Furthermore, the actual heatsink item has slightly fewer fins, spaced slightly further apart, than my original. Both facts together make me suspect this unit might be intended for an Intel LGA 1150 i3 cpu, whereas mine is Intel LGA 1150 i7. The vendor's site had the facility to select the appropriate motherboard cpu socket type, eg, LGA 1150, LGA 1151, LGA 1155, LGA 1200 etc, but no facility to specify i3, i5, i7, i9 etc. That is, a dodgy web design by accident or design, & i seem to have fallen into the trap.

I thought about ringing the vendor & chucking a tanty, but realised it would not help ofc, & anyway my hands are tied. Best case scenario would have been vendor apologised & offered to replace it with what i actually ordered, but... natch they'd need me to send the received one back to them. I can't do that... i can order stuff online & have it delivered here, but every time i do it [over the last 22 years i've been doing so], i accept i'm gambling, coz if items are defective or wrong, i just have to grin & bear it... coz i can't get myself to a post office to do the necessary stuff for returns. Sigh, being fucked in the head is such fun.

Given the preceding, i decided i had nothing to lose by bunging this new unit into Pooter & giving it a go. If it can't adequately control the cpu temperature & i have to again shutdown & revert to Lappy to plan my next steps, then so be it.

So far, it is holding the temp well [26 C], but i can see it is doing so by running ~1000 rpm faster than the old one would have [~2600 rpm atm, with only browser, Thunderbird, GnuCash, KeePassXC, Goodvibes, text editor open, & thus low load]. Even when i ran a full system update the temp only peaked at ~45 C, which is actually good.

So we beat on, boats against the current, borne back ceaselessly into the past.

It seems the new #Ryzen laptop CPUs come with 3 performance cores and 5 efficiency cores. For daily business tasks, this probably helps save battery. But what if a laptop is used for #Rust compiling 4 to 6 hours a day? Would the older Ryzen with 8 strong cores perform better than the new Ryzen's 3P+5E core strategy?

IMHO, AMD, Intel and ARM should step up and start provide some cheap and accessible hardware that you can use at your home, and not intended for rolling out cash (i.e. something like NUC), but only to allow kernel maintainers and operating system developers to test their server features.

Cheap means here something like less than 1000 euros.

E.g., in Intel SGX the latest and greatest are NUC7's from 2018 and for VM based confidential computing there's nothing appropriate.

Shame on you CPU companies!
