Vorbeşti prostii.
La modul super-simplificat, dacă îi spui procesorului să adune 486+100 şi rezultatul e... 585.99999999998898989, software-ul îţi va da eroare, dar cauza e hardware.

Daca s-au gasit workarounds cu setari din BIOS, poate sunt sanse ca un BIOS destept sa rezolve problema.

Si tu vorbesti prostii, e vorba de gcc, acolo pot aparea oricand erori.

In afara de instabilitate(cauzata de diversi factori) ce probleme hardware poate avea un procesor?!

Uite aici un exemplu.
https://en.wikipedia.org/wiki/Pentium_FDIV_bug
Quote:
The Pentium FDIV bug was a computer bug that affected the floating point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor could return incorrect binary floating point results when dividing a number. Discovered in 1994 by Professor Thomas R. Nicely at Lynchburg College,[1] Intel attributed the error to missing entries in the lookup table used by the floating-point division circuitry.[2]
In December 1994, Intel recalled the defective processors.

Se poate intampla. Ne-am obisnuit ca procesoarele sa fie in general bulletproof, dar la o arhitectura complet noua ca Ryzen se pot strecura anumite probleme initial. E ceva sa asezi in perfecta ordine 4.8 miliarde de tranzistori.

De-aia am zis "la modul super simplificat". Nu m-am referit la cazuri specifice.
@ Dreamcatcher - o grămadă de hardware bugs au existat de-a lungul vremurilor. Click me. Sau dacă vrei ceva mai specific, click this instead.

Sunt si acum baze de date care returneaza rezultate nu tocmai exacte pentru calcule in virgula mobila. Ma refer la calcule pe date in format "double".

ala nu e bug e vorba de precizia tipului folosit. Daca ai nevoie de calcule foarte exacte nu folosesti float/double ci numeric, decimal (care au si ele precizie limitata, insa mult mai mare)

Deci probabil 1998X o sa fie $999.
Oricum, pret foarte bun. Numai sa ajunga si pe piata la banii astia

cu 16core/32T o sa fie visul umed al graficienilor si creatorilor de continut digital Pretul e corect . Intel a cam dat-o in balarii rau cu lansarea "pe foaie" (am vazut reactiile tuturor review-urilor din www). Cele cu 16 - 18 - 20Core au fost puse pe foaie doar sa nu zica lumea ca nu au si ei .... iar cele 24lane sunt 'meh ) cam la fel
