    Max OC pe 1070 ca performanta e sub max OC pe 980 Ti, asta era la baza ideii.

    "GTX 980 Ti @ 1505 MHZ core = 8.464 TFLOPs, 265 Gigatexel/sec, 144.48 Gigapixel/sec, 384 GB/sec memory bandwidth - at 8 GHZ."

    "Even if you take a GTX 1070 and OC it to the MAX ~2125 MHZ core, and ~9 GHZ VRAM, you are looking at:

    GTX 1070 @ 2125 MHZ Core = 8.16 TFLOPs, 255 Gigatexel/sec, 136 Gigapixel/sec and ~290 GB/sec memory bandwidth

    And most GTX 1070s cannot hold 2.1 GHZ core, they may bump it, but unless supremely lucky, the upper limit for any Pascal GPU is ~2 GHZ and not much more."

    "When tweaked to max frequencies, the GTX 980 Ti is significantly Faster/More Powerful than any GTX 1070."

    Trebuie si desen?

    Olds asta incerc sa le explic si eu, High end inseamna high end si GFLOPS chiar conteaza.

    Normal ca conteaza, doar ca depinde de cum e exploatat cipul in diferite aplicatii.

    Perfect de acord ca conteaza cum este exploatat cipul, oricum tind sa cred ca doar testele privind puterea de procesare ( GFLOPS) sunt singurele teste obiective, restul tine de optimizari si cum sunt gandite sa functioneze arhitecturile.

    Doar ca degeaba puterea de procesare e mare daca nu e exploatata corespunzator acolo unde te intereseaza pe tine, sa zicem in jocuri. Ramane speranta unor optimizari ulterioare, care daca intarzie mult, se pierde avantajul.

    Iertati-l pe dnu Older,isi apara investitia (Gtx 980 TI).
    Mai gaseste pe youtube o duma d-asta si bam! placa lui iz za biest in 1080p.
    Intrebarea estem: 980Ti lui face fata in 8K? (cica asta este ultimul raget pt high-end),

    Normal ca 1070 este peste 980 TI,OC sau nu.

    Inca e bine, la procesoare a scazut la sub 5% per generatie de vreo 7 generatii.

    Cand Intel ne arunca un "nou" cpu pe piata,ei fac teste in Sysmark/Passmark.De aceea ne arunca in fata sliduri cu +20-30% perf.
    In jocuri este alta poveste,doar +5-10% perf

    10% ala vine de fapt de la DDR4.

    @takada Lasa ca e foarte performanta vega 64 in 8k.

    Nu-i mai scump si mai lent?

    Pretul recomandat de producator e acelasi, 999 USD. Depinde in ce testezi, lumea procesoarelor nu incepe si se termina cu Passmark. Dar exista thread special pentru procesoare, nu e cazul sa continuam aici.

    Mai degrabă preţ de highend la midrange şi low-mid la preţ de midrange. Comparând doar chipurile full, saltul e păstrat în mare - de exemplu de compari 980ti cu 1080ti, ultima e de aproape 2 ori mai rapidă în 4k https://www.techpowerup.com/reviews/...ning_Z/29.html

    Saltul e chiar spectaculos de la Maxwell la Pascal. Dar de la Pascal la Volta va fi o trecere mai graduala (diferenta maxima se va atinge in mai multe etape), respectiv se sugereaza ca 2080 (daca asa se va numi) nu va fi cu mult peste 1080 Ti. Cele cu adevarat tari le lasa pe mai tarziu. Diferenta majora va fi in eficienta/consum.

    Din seara asta am trecut si eu in tabara nvidia, cu un GTX 1080 de la Gigabyte, multumita lui AStateOfMind.
    N-am apucat sa fac prea multe teste inca, doar Witcher 3, unde se misca de 2x si ceva mai bine. Sa vedem daca peste 2 ani AMD va reusi sa ma convinga sa revin inapoi

    Si ce zici, nu te simti pacalit ca ai dat 1800 lei pe un GTX1080 cu 3 ventilatoare, cand puteai lua un mult mai convenabil si plin de tehnologii de ultima oara Vega 64 stoc cu 4000 lei?
