Ako se ne varam Microsoft je izjavio da trebaju patchati scheduler.

mislim da je i wendall spominjao da su odmah u startu iz amd trebali ici na foru odvajanja u dva virtualna bloka pa nebi bilo toliko naglašena problematika.

opet s druge strane vjerujem da inzinjeri iz amd nisu vesla cicali i ziher imaju razlog zasto su odabrali ovaj nacin konfiguracije.

ugl da se launch odradio kak spada i da se nije toliko zurilo nebi sad prakticki imali o cemu piskarati

dakle zakljucak je da uz to sto su intelovi procevi losiji jos su i dosadni :D

Dobro kazes...

A ja eto silno iscekujem dostavu tog ryzena da mu ugasim 4 jezgre i prve dvije probam dic dosta vise od drugih pa da vidimo gaming... Jer vidim da to nitko po testovima ne radi...

Zanimljiv plan :fiju:

Da dobar plan, pogasiti sve kaj ne treba :D

Mislim da se nece bas oduseviti oc mogucnostima, cak i uz 4 ugasene jezgre...

A bumo vidli... Obzirom da nemam nit sam imal 7700K, ne bum osjetil nikakav pad performansi :) Samo me hebe ovo hladjenje i bracket za AM4, gotovo sam siguran da ce tek iduci tjedan stici, a ploca i cpu ovaj tjedan...
A i mislio sam ja ja sve, uzeo sam novi monitor u kompletu sa ryzenom tak da ako nebum zadovoljan sa konfom, svejedno cu vidjet razliku haha

Krasno. Dakle istina je ono sto su ljudi govorili da pod prst metodom proc i nije toliko zagrijan :)

Malo su to glupo napravili,ako su već offsetali temperaturu za +20C onda su to trebali negdje i napisati a ne ovako izgleda kao da možeš jaje ispeći

Ima to sve (i uz druge stvari) u onome linku sa amd stranice što je nidjo89 stavio. Iako ne kužim baš razlog to sa temperaturom, na kraju su ispali u pravu ovi što su mjerili sa mbo, 3rd party programi nisu mjerilo (nit su ikad bili za amd) i trebaju update

Prst metoda nikad ne laže (techspot review)

Možda iz razloga što BIOS-i nisu popeglani u vidu XFR-a. Da se ne naskodi procesorima?

Kažu

Citiraj:

The primary temperature reporting sensor of the AMD Ryzen™ processor is a sensor called “T Control,” or tCTL for short. The tCTL sensor is derived from the junction (Tj) temperature—the interface point between the die and heatspreader—but it may be offset on certain CPU models so that all models on the AM4 Platform have the same maximum tCTL value. This approach ensures that all AMD Ryzen™ processors have a consistent fan policy.

Specifically, the AMD Ryzen™ 7 1700X and 1800X carry a +20°C offset between the tCTL° (reported) temperature and the actual Tj° temperature. In the short term, users of the AMD Ryzen™ 1700X and 1800X can simply subtract 20°C to determine the true junction temperature of their processor. No arithmetic is required for the Ryzen 7 1700. Long term, we expect temperature monitoring software to better understand our tCTL offsets to report the junction temperature automatically.

Glupo

14.03.2017. 12:59

Glupo, al opet puno bolje nego da cpu prijavljuje -20° :D
Zbog tog offseta su mnogi revieweri primjecivali visoke idle temperature...

sti	14.03.2017. 13:16

The plot thickens, više ne treba Noctua D15 ili voda za držati 1700X na 4 GHz.

Hoće li ikad svanut dan da AMD neće radit kerefeke oko prijave i očitanja temperature. Sjećam se kad sam prodavao jedan 3000+ Venice, lik ga stavi na ploču (neka s939 Soltekica bila) upalimo komp a ono sve pišti, odeš u BIOS ovaj javlja CPU core temp 99°C. :D
Lik me gleda kao kaj si mi donio pokvaren CPU. Reko gle kod mene na DFI LP radi normalno :D

S FX-evima isto jebo lud zbunjenog, javi da je na 40°C a ono bazu proca ne možeš dirat koliko je vruća.

shar	14.03.2017. 13:48

Malo kasnim sa ovim postom ali zašto bi ljudi gasili jezgre u biosu kad u task manageru mogu odabrati koje jezgre igra može koristit. Pukneš igru na 4 jezgre i radit će bez problema, a imaš još 4 za sve ostalo što želiš da se vrti u pozadini i neće smetati jedno drugom.

Such topics as Windows 7 vs. Windows 10 performance, SMT impact, and thread scheduling will no doubt still be debated, and AMD has correctly pointed out that optimization for this brand new architecture will only improve Ryzen performance going forward. Our own findings as to Ryzen and the Windows 10 thread scheduler appear to be validated as AMD officially dismisses performance impact in that area, though there is still room for improvement in other areas from our initial gaming performance findings. As mentioned in the post, AMD will have an update for Windows power plan optimization by the first week of April, and the company has "already identified some simple changes that can improve a game’s understanding of the 'Zen' core/cache topology, and we intend to provide a status update to the community when they are ready", as well.
It is refreshing to see a company publicly acknowledging the topics that have resulted in so much discussion in the past couple of weeks, and their transparency is commendable, with every issue (that this author is aware of) being touched on in the post.

Znači, AMD će napraviti patch za to, a ne Microsoft?

robimarko-bug

14.03.2017. 14:16

Microsoft vjerovatno nije previše briga.

Manuel Calavera

Tako zvuči. Ovo je orginal sa AMD stranice pod SMT

Citiraj:

For the remaining outliers, AMD again sees multiple opportunities within the codebases of specific applications to improve how this software addresses the “Zen” architecture. We have already identified some simple changes that can improve a game’s understanding of the "Zen" core/cache topology, and we intend to provide a status update to the community when they are ready.

Kažem, jasna stvar da se ono tipa u rally 100 fps sa SMT, 120 fps bez ne smije događati

Ovo je od "Power plans"

Citiraj:

In the near term, we recommend that games and other high-performance applications are complemented by the High Performance plan. By the first week of April, AMD intends to provide an update for AMD Ryzen™ processors that optimizes the power policy parameters of the Balanced plan to favor performance more consistent with the typical usage models of a desktop PC.

Microcode update koji ide preko win?

A što je ovo pod "thread scheduling"?

Citiraj:

As an extension of this investigation, we have also reviewed topology logs generated by the Sysinternals Coreinfo utility. We have determined that an outdated version of the application was responsible for originating the incorrect topology data that has been widely reported in the media. Coreinfo v3.31 (or later) will produce the correct results.

Ja bi ugasio jezgre samo za testove i da vidim jel ise na npr 4.4 ako ugasim pola itd... ili svih 8 ali samo dvije dic na 4.2 4.3, a ostale manje i vidit jel ce se poboljsat performanse u gamingu...
Ne mislim pri tome da bi to ostavio kao stalan setup...

Pa evo ja uzimao u alzi i pisalo je da ploca nema na stanju ali da 5 kom stize jucer i vidim odma su poslali i vise ih nema na stanju... Znaci moze se kupit ali treba pricekat koji dan...
