d) 8c si 12c pe 7 nm exista ca ES, 16c pe 7nm nu au aparut inca la vedere nici macar ca ES-uri;

+ boost nu e pe toate core-urile, ci pe 1/2/4 max.
Iar daca ii maresti voltajul la ala 8c poate reusesti sa il duci si mai sus de 5.1Ghz, doar ca nu e garantat din fabrica acest lucru.

depinde binning, asta unu la mana.
Si doi la mana, depinde 8c-ul daca va avea 1 chiplet sau 2. Tind sa cred ca versiunile full bune de chiplets ajung in Rome -> thread ripper -> 16 core -> 8 core.
Also e f posibil sa nu scoata mai mult de 12c/24t pentru inceput AMD, si sa tina 16c-ul pentru q4 2019/q1 2020.

Am intele bine? Noile Procesoare vor suporta viteze mai mari la memorii, inclusiv un OC mai generos dar asta inseamna o pierdere la Infinity Fabric bandwidth? Practic "unde dai si unde crapa..."

Nu stiu exact cum o sa fie dar asta e buba cu infinity fabric... la fel e si la intel la procesoarele HEDT care folosesc "mesh" ... momentan frecveta mare si latente bune merg pe configuratia RING cum foloseste intel la procesoarele "normale".
Dar e mult loc de imbunatatiere la infinity, daca o aduc macar la nivelul de mesh, la cum scaleaza ryzen cu frecventa ram-ului o sa aiba un sport consistent de performanta.

Infinity Fabric face transferul intre chipleturi, nu are sens sa fie legata de frecventa memoriei.

Si da, scade performanta putin in jocuri si creste in productivitate.

Edit: Asta daca ai placa video de top 1080ti,2080ti,Radeon 7

Buba este ca windowsul are un scheduler antic de ***** si arhitectura ring-bus merge rapid ca ai latente mici de la core la core. Problema e ca e foarte scump procesul de fabricare ring-bus si urmatorul Intel Core i9 cu 10 core o sa coste dublu fata de 9900k

Oricum la intel pentru moment totul e scump... ca nici 10 cores pe mesh nu l-au vandut ieftin

Salutare.
Voi fi nevoit să construiesc alt PC pentru junior și cred că voi alege o platformă AMD, mai exact un Ryzen 7 2700X, aș vrea eu, doar că nu știu ce placă de bază să aleg, cu X470 și ce module de RAM, trebuie ceva mai special?
Mulțumesc anticipat pentru răspunsuri/sugestii.

Nu trebuie cl14, merg multe memorii. De exemplu, cele mai ieftine pe care le-am testat eu si merg bine sunt astea. Testat si astea de 16 gb si de 8 GB. Crucial de 2400 Mhz nu merg bine.

ca si placi de baza Asus pe AMD sunt medioacre din perspectiva VRM-ului.(mai putin hero si crosshair)
msi-ul sta mai bine, in special asta care e si mai ieftin. Daca ai timp 30 minute, verifica din nou videoul lui buildzoid de pe youtube, trece prin majoritatea placilor de baza pentr AM4.
asus are un plus la BIOS-uri(si support mai bun pentru memorii), msi e ceva mai ciudatel.

Wow, mulțumesc de info.
Plăcile de bază AM4 de la Gigy nu au scānteia?
Asus am īnțeles că au redus mult VRM-ul și la z390.

Un VRM puternic īți este necesar doar dacă vrei să faci O/C puternic. Prietenul meu a luat Gigabyte și nu are niciun fel de problemă.
