Chirurgia cranio-cerebrală minim invazivă
Tehnicile minim invazive impun utilizarea unei tehnologii ultramoderne. Endoscoapele operatorii de diverse tipuri, microscopul operator dedicat, neuronavigația, neuroelectrofiziologia, tehnicile avansate de anestezie, chirurgia cu pacientul treaz reprezintă armamentarium fără de care neurochirurgia prin "gaura cheii" nu ar fi posibilă. Folosind tehnicile de mai sus, tratăm un spectru larg de patologii cranio-cerebrale. www.neurohope.ro |

Se poate evidentia acum impactual Meltdown/Spectre cu noile benchmark-uri :

Quote Intel classifies four of the Specter NG vulnerabilities as "high-risk"; which in Intel language is translated as: super dangerous. The danger of the other four is rated as medium. According to c't/Heise, Specter-NG risks and attack scenarios are similar to those of Specter - with one exception. C't calls the Intel vulnerabilities and their procs a Swiss Cheese due to the many security holes Aww snap...inca vreo cateva bucati. Cam exagerata comparatia de la final, dar parca prea multe intr-un timp prea scurt. Ca s-o dam in dodii "á la mirel", cpu-ul intel e o bucatarie care tocmai a fost invadata de cativa gandaci, unii mai mici, altii mai mari. Iar dezinfectantul s-ar putea sa-l faca pe bucatar mai lent. |

deci toate procesoarele intel se vor transforma in pentium 4 pana la urma? pentium inside e noul logo?

Confirmarea ca ce ?!
procesoarele Intel se vor transforma in Pentium 4 (din 2000); sau performanta va fi afectata doar cu un procent mic ? |

HPET este tehnologie veche si atunci cand procesoarele Intel au capatat turbo, a fost inlocuita de TSC pentru a putea sincroniza nuclele la frecvente de lucru diferite. HPET lipseste ca optiune din BIOS-ul multor placi de baza si in mod normal trebuie dezactivat. Since Windows 7, the operating system runs tests on the underlying hardware to see which hardware is best used for timekeeping. When the processors Time Stamp Counter (TSC) is suitable, the operating system uses the TSC for timekeeping. If the TSC cannot be used for timekeeping the operating system reverts to the High Precision Event Timer (HPET). If that does not exist it reverts to the ACPI PM timer. For performance reasons it shall be noted that HPET and ACPI PM timer cause IPC overhead, while the use of the TSC does not. The evolution of TSC shows a variety of capabilities... Sursa: http://www.windowsti...com/description Ce a facut anandtec activand HPET este o magarie asa cum tot o magarie este si faptul ca la Intel au folosit Balanced ca power plan si la AMD au folosit High Performance si tot o magarie este faptul ca au folosit un driver video vechi, optimizat pentru Ryzen dar nu si pentru intel Coffee Lake. Deci, ce relevanta au graficele alea? Si ca fapt divers, pentru ca Spectre si Meltdown au devenit tragedii globale, vreau sa ridice mana sus ala ca a fost afectat de cele doua gauri negre din procesoarele Intel.

https://en.wikipedia...e_Stamp_Counter
https://en.wikipedia...ion_Event_Timer The Time Stamp Counter (TSC) is a 64-bit register present on all x86 processors since the Pentium. The High Precision Event Timer (HPET) is a hardware timer used in personal computers. It was developed jointly by Intel and Microsoft and has been incorporated in PC chipsets since circa 2005. Ca fapt divers TSC - single core HPET - multi core Oare ce alte inovatii Intel nu functioneaza cum trebuie pe propriile produse. Intradevar e o magarie sa testezi procesoare AMD cu minuni create de Intel. Edited by Arthos, 04 May 2018 - 21:40. |

Folosind sursele tale:
"This article needs additional citations for verification." "The High Precision Event Timer (HPET) is a hardware timer used in personal computers. It was developed jointly by Intel and Microsoft and has been incorporated in PC chipsets since circa 2005. Formerly referred to by Intel as a Multimedia Timer,[1] the term HPET was selected to avoid confusion with the multimedia timers as a software feature introduced in the MultiMedia Extensions to Windows 3.0." "...TSC is the preferred clock source due to its much lower overhead, but it uses HPET as a fallback. A benchmark in that environment for 10 million event counts found that TSC took about 0.6 seconds, HPET took slightly over 12 seconds, and ACPI Power Management Timer took around 24 seconds." HPET a functionat chiar foarte bine pe generatia Intel core 2 duo si quad, dar s-a renuntat la tehnologia asta si s-a trecut la TSC. Edited by sys, 04 May 2018 - 22:16. |

Zic sa nu va mai bateti capul. Doar zilele trecute 3 fosti angajati ai AMD au semnat cu Intel inclusiv cel ce a proiectat Ryzen.
Deci probabil urmatorul CPU Intel o sa semene foarte mult cu un AMD. Asa poate va impaca pe toti. |

BTW, stirile despre Meltdown si Spectre au cam disparut de la mijlocul lui Februarie. Masi apare cate una, dar numai legate de update-uri, nicidecum una pe care o astepti cu sufletul la gura. Nu tu atacuri confirmate, nu tu dezastre...[...] Edited by Dany_Darke, 06 May 2018 - 06:24. |
