Déjà on parle de quoi ? De quelques types qui ont chopé un soit disant 0x114 qui sort de je ne sais quel forum au fin fond du dark web, qui ont appliqué un protocole de test tout aussi obscure dont personne ne connaît les détails (quel bios ? quel version de Windows? Quel paramètre PPM ?…etc). Et le 0x114 n’est pas encore sorti officiellement chez les fabricants de mobo ! La blague. Donc si je suis la logique faudrait ne pas croire Intel car c’est le mal absolu mais par contre gober de facto les dires du premier venu clamant avoir fait des tests en chopant une version underground du dernier microcode. Tout cela n’est pas très sérieux.
Moi aussi je réitère que je ne crois que ce que je vois avec des tests et des protocoles venants de sources crédibles, pas de guignols. On sera fixé dans 3 semaines avec le volet nº2 officiel de ces optimisations et la confrontation avec des tests indépendants sur la base de bios officiels, des bonnes versions de Windows 11 & co. C’est visiblement toutes une chaîne cohérente qu’il faut avoir pour obtenir un combo fix le meilleur possible. Sur cette base on pourra objectivement dire si c’est définitivement un fail ou pas.

1) Citation :
Intel confirms that the first set of issues are caused due to faulty collaborative power management between the OS and the processor. UEFI CPPC establishes a set of standards by which an OS can send information about the performance demands of its various processes and services to the hardware power management unit, letting it alter performance parameters such as core scheduling/parking, voltage, clock speeds, among others. Specifically, Intel says that the processor power management (PPM) settings at the OS-level for Windows 11 24H2 are faulty. This alone accounts for a massive 6% to 30% loss in performance. Intel reports that all these issues have been solved by version 26100.2161 (KB5044384), or the November 2024 "patch Tuesday" update of Windows 11 24H2.

Réglé via Windows Update depuis le patch du mardi du mois de novembre dernier.
2) Citation :
The second set of performance issues are caused due to Intel Application Performance Optimizer (APO) not delivering on performance uplifts along expected lines. APO is an application-specific set of processor optimizations Intel has been releasing with its processors over the last few generations. A faulty implementation of APO on the OS level meant that PPM settings on APO profiles don't apply correctly. Another issue noticed was that motherboard BIOS versions released to CPU reviewers around the time of Core Ultra 9 285K reviews (October) didn't have APO enabled by default. These together cost anywhere between 2% to 14% performance in games that have APO profiles. Intel says that these issues are solved with the November "patch Tuesday" update to Windows 11 24H2, just like the first set of problems.

Egalement réglé via ce même patch du mardi de novembre dernier.
3) Citation :
Another rather bizarre set of issues affected games using EAC (Easy Anti-Cheat), triggering a BSOD at launch, when running on Windows 11 24H2. This was due to a bug with the kernel-mode driver (KMD) of EAC when paired with Windows 11 24H2, which was allegedly exacerbated with virtualization-based security (VBS) being disabled by the user (Microsoft enables this by default for 24H2). Intel says that it's been working with Epic Games to distribute an updated EAC KMD to game developers.

3) Pas windows mais c'est juste des crash spécifiques avec des anti cheat, donc pas sur les performances, en cours de résolution.
4) Citation :
The fourth set of performance issues are caused due to combination of incorrect default settings in motherboard UEFI setup programs. Some of these are glaring omissions, such as PCI Resizable BAR being disabled by default, APO being disabled, wrong Compute Ring Frequency, a setting that affects intercore latency, and integrated memory controller Gear mode, which affects the ratio between the IMC frequency and DRAM frequency, enabling Gear 4 even in lower frequencies that can work perfectly stable with Gear 2. These could affect performance by anywhere between 2% to 14%. Intel says that it's been pursuing motherboard vendors to release BIOS updates that fix these defaults, and these should already be in circulation.

Des bios incluant ces fixes sont d'ores et déjà en circulation.
5) Citation :
Lastly, we reach the heart of the matter, the 0x114 Microcode Update. This update is said to include several "performance enhancements," and the company's motherboard partners are working to integrate it with their future BIOS updates. Intel says that the Microcode should cause a "single digit percentage performance enhancement" across games. This is a geomean obtained over 35 games, which means the 285K should end up faster than the Core i9-14900K, and inch closer to the Ryzen 7 9800X3D in gaming performance.

Reste donc le microcode et le CSME.
https://www.techpowerup.com/review/ [...] -new-bios/
TPU c'est pas le dark web, à nouveau reste le microcode / CMSE mais les patchs windows et les derniers bios en date n'ont rien changé ou marginalement.
Jusqu'à présent ils ont corrigé les sous performances de ARL entre la 23h2 et la 24h2 de windows 11 mais y a pas de gain de performance.
Citation :
In a YouTube interview with HotHardware, who also work as consultants for Intel, Robert Hallock mentioned "3-8%."—let's hope these gains materialize and can help to boost Arrow Lake to competitive levels.
|
Bref reste maintenant à vérifier si le microde et le CSME apporte au final les 3 à 8 % de gains mentionnés  .
