rezultat timpuriu... cred ca o sa fie fun 5.6 ghz ... dupa ani de zile de frecventa in urma Intel. x670e Carerra deja e listat ddr5 6660 iar in jocuri gen Spiderman peformanta vs ddr4 e +30%.sa vedem care e marja de overclock pe am5 fara binning.

Nou chipset amd. Redditarzii raporteaza ca impreuna cu noul build windows 11 release preview (dev channel) au performanta mai buna.

Practic tot softul de testare (win,hwinfo, y-crunch, aida64 si de ce nu, project hydra) e deja pregatit pt lansarea din septembrie.

angstronomics: Ryzen 7000 Desktop Preview


fara cont - pastebin

SPOILER:
Each 8-core 5nm Zen 4 CCD is made up of 6.57 Billion transistors. This packs 58% more transistors than the previous 7nm Zen 3 CCD (4.15B) despite the die being over 10% smaller. Thus the average transistor density across the whole die goes from below 50 MTr/mm? to over 90 MTr/mm?.
Consequences
The doubling of transistor density at the heat generating sections of the die has a major impact on the cooling of the chip. Cache has a comparatively low heat output per area, while logic is where the hotspots are located. Due to thermal limits at the logic hotspots, there is increasing use of “dark silicon”, meaning a lower percentage of transistors can be switching and producing heat at any one time.

Cooling Challenge
Ryzen 7000 Desktop will therefore represent the ultimate cooling challenge seen thus far. The die can approach 2 Watts/mm? if your cooler is up to the task. The smaller heatspreader area on Ryzen 7000 package design only makes things worse.
Due to the cooling difficulty and higher power limits on Ryzen 7000 Dekstop, the philosophy has changed to follow a more laptop-like approach. Instead of fixing a clockspeed or power limit, the processor is now temperature limited. This means maximizing performance for a given cooling capability. The processor will adjust to stay within the temperature limits. This also means a more significant performance difference that changes with cooling ability.


tl;dr: Ryzen 7000 Desktop will therefore represent the ultimate cooling challenge seen thus far

asa ca e justificat sa intindeti mana dupa potul cu nitrogen /s

O sa fie interesant la temperaturi,cred ca o sa fie mai dificil de stapanit zen4 fata de 5xxx.

Am observat azi "noutatea" legata de voltaj si facut restore la o imagine din 8 august.

Acelasi BIOS, cu imaginea din 8august si penultimele chipset drivers am 1.5V, cu updates de win11 la zi am ce e in poza 2. Am dezinstalat KB5016691 si nimic.

La mine e noutate.
LE: am găsit problema, cateva ore pierdute useless. Cu memory integrity OFF nu mai e limita de 1.45V in SC.

Ii bagă voltaj la greu... să vezi cate se vor prăji... m'uie MS...
Mai aștept, nu bag win11, nu-mi place. Am la serviciu c?teva și e mai greu de lucrat cu ele...

Sa fim seriosi, cine are bani de dat 400-700 coco pe procesor, 200-300-400 coco pe mobo, 200-300 pe DDR5 nu cred ca se va impiedica de inca 200-300 coco pentru un cooler bun. (poate chiar custom loop)

Oricum Intel ne-a obisnuit, AMD doar continua.
Si din ce se anunta Nvidia si Radeon le vor urma.

Asta cu update-ul de bios a inceput de la Windows 10, vine prin windows update iar cand ii dai restart, te trezesti cu mesaj de update bios / firmware.

Daca face update de bios, o face pentru ca primeste de la intel/amd ca security update, in loc de drivers&shit.
Aici, sincer, mai e si vina intel/amd ca vin gresit. Degeaba devifezi drivere&shit la advaced update din win, daca producatorii (intel/amd/plm) le baga la MS ca security.

N-am primit niciodata update de BIOS prin windows update pe W10, nici n-as vrea asa ceva.
Cel putin pe seria Ryzen 5000, unele BIOS-uri mai mult stricau decat reparau ( vedeti problemele cu USB de ex.) asa ca prefer sa ma documentez inainte sa instalez bios nou.

Pai fix din motivul asta le-au bagat: pentru ca sunt unii care ignora update-urile de securitate din release-ul de bios. Am inteles ca doar update-urile de urgenta sunt pushed prin windows update - de exemplu Lenovo a facut push la un update de bios care repara o problema care cauza defect fizic la unele Thinkpaduri. (Rescria un chip continuu pana murea chipul).

Era absolut normal ca seria 7000 sa fie hot ca dracu, cauza principala fiind suprafetele mult mai mici de disipare a caldurii spre cooler. Poti sa ai mama waterblock-ului, ca problema nu e acolo. Problema e ca ai deja pastila cu aprox 50% mai mica, IHS cu suprafata mai mica pentru ca are toate taieturile alea, si peste toate astea vii si cu extra consum in pastila aia mica, cu vreo 50% in plus.

Am waterblock pentru Threadripper(mult mai mare) cu lapping facut pus pe 5950x, pompa D5, 2x radiatoare de 480mm cu 8 venturi de 120mm si am incercat vreo 3 paste pana acum(toate top-end). Cu PBO on la 220W limita mi s-a dus ieri in 88C intr-un anumit workload semi-threaded.

Depinde si unde faci load-ul ala, cand lucreaza la voltaj/frecvente mari pe putine core-uri explodeaza temperatura, in multi-thread full load sta la ~65C pentru ca se disipa mai bine caldura aia pe pastila si voltajul overall e mai mic.

Deci o sa faceti fix pix cu loop-uri de 50000000 euro pe seria 7000, bottleneck-ul termal e in interior.

Avem nevoie de alte IHS-uri, poate diamant sintetic (cel mai bun conductor termal), ori ceva cu carbon (nanotuburi sau graphene), cuprul e la limita lui fizica de conductivitate termala pentru chestiile astea.
Sau altceva decat siliciu dedesubt, ceva sa reziste lejer la 150C.

Stau si ma joc cu un 7600x iar un aio de 240 face fata cu brio in conditiile un care am 27-28 ambient. Cand zic face fata inseamna impins la maxim are 87-88 grade in cinebench r23. Eu unul sunt curios cum vor raci placile de baza corespunzator in conditiile in care cu radiator pe el chipsetul in mod pci-e 4.0 are 70 grade in idle. In rest e faina noua generatie, ipc bun frecvente bune dar nu e ca si cum seria 5xxx e limitata in ceva in momentul asta.
