-5760x1200 isti deal = 1080MB.
Do note, da NVIDIA spravlja stvari v sistemski ram (moj zadnji članek) in GPU-ji lahko berejo sočasno čez PCI-Ex in iz video rama.



senitel kaj to pomen? Da NV spravlja v sistemski ram? ce lah nahitr razlozis in pri cem bi se to poznalo?

Sicer pa bi tudi jaz raje videl na svoje oči to zadevo, da uporablja sistemski ram.

Toliko, da veste - 7850 se presenetljivo dobro navija (sam imam SAPPHIRE 7850 navito na 1101/1501 brez spreminjanja voltaže in vse dela bp 24/7 + temperature tam do 55 stopinj, 3d mark 11 pa mi je uspelo pognat na 1113/1529 brez spreminjanja voltaže - ss pridejo jutri, seveda pod primerno temo)

S tem sem hotel povedat, da priporočam nakup ;).

PS: Po drugih forumih sem zasledil, da so jo "spravili" tudi že čez 1300, kar je več kot 50% OC 8-O

Zgleda da se celotna 7k serija super navija. Tut js sm svojo 7950 navil iz 810 na 1200mhz.

fr4nc ::

Evo... danes sem se malo igral z voltažo ter navijal grafično (Sapphire 7850) :).

Končen dosežek je 1293/1566 iz stock 860/1200 (+50,3% na jedru; +30,5% na spominu). Preseneča me predvsem frekvenca spomina, ki je dejansko 6264MHz ;).

Si pa dal odgovor.. 1fps na 20 ali 1fps na 200 je malo razlike ne.. Kolikor jaz vidim fpf-ji še zmeraj tudi če je core +50% žal ne zrastejo za več kot 15% kar vsakodnevno teško odtehta sam OC.. Drugače je bilo včasih in na grafah nižjega ranga ko je 15Mhz na jedru in ramu prineslo tudi 15% gaina fps-jev.

3d mark 11:

navita (1293/1566) : 7316 točk
razlika v točkah 35,7%, drugače pa je razlike cca. 20% pri fps-jih (npr. prej 30fps, zdaj 36fps)

Na enem forumu sem zasledil tole:
My XFX 7850 does 1ghz core @ 1.075V (stock) & 1475mhz memory, ASIC is 83.6%, is that average? Power limit is at +4%.

- Anything around or above 80% is good, over 85% very good, over 90% rare and potentially great.

Kaj pomeni ta ASIC - sem iskal pri stricu googlu pa nisem našel razlage... Ve kdo kaj je to?

... index, ki so ga uvedli v novejsim GPU-Z-jem za zadnje generacije kartice.

http://www.xtremesystems.org/forums/sho...

The next new feature is ASIC quality, designed for NVIDIA Fermi (GF10x and GF11x GPUs) and AMD Southern Islands (HD 7800 series and above), aimed at advanced users, hardware manufacturers, and the likes. We've found the ways in which AMD and NVIDIA segregate their freshly-made GPU ASICs based on the electrical leakages the chips produce (to increase yield by allotting them in different SKUs and performance bins), and we've found ways in which ASIC quality can be quantified and displayed. Find this feature in the context menu of GPU-Z. We're working on implementing this feature on older AMD Radeon GPUs.

According to Alexey Nikolaichuk (the author of RivaTuner and MSI Afterburner), the correlation between voltage and quality is like follows:
ASIC quality < 75% - 1.1750 V;
ASIC quality < 80% - 1.1125 V;
ASIC quality < 85% - 1.0500 V;
ASIC quality < 90% - 1.0250 V;
ASIC quality ≤ 100% - 1.0250 V.

Drugače pa očitno je nekdo navil, če je test/link iz 3dmark-a... In verjetno je stabilno ja, samo podatka o voltaži ni - to bi morali dodati k 3dmark-u bi bilo zelo koristno prav tako tudi od procesorja

je, ker je to 2x7970-torej dva 7970 procesorja na enim PCB-jem, kar pomeni da je enako kot 7970 crossfire, vglavnem to ni nic novega, smo ze videli 6870x2
Get educated or get ripped off!

fr4nc ::

we could be seeing cards clocked well above 1GHz as well. The HD 7970 X2 will go head on with Nvidia's GTX 690, but it should be a lot more competitively priced.

Torej na SLO trgu cca. 800€ mogoče kaj manj?
