hvor mange gange hurtigere er et 5870, 5850 eller 5870X2 end et 8800GTX sku jeg høre ad fra min fætter, som skal spille det ny online starwars spil næste år engang 🙂

jeg har sagt at det bliver hans livs upgrade, men i virkeligheden ku det være at det var 8800GTX der var det (havde bærbar fra 2003 før, lol)

jeg har sagt ca. x4 speed men det er jo svært at sige, når der ingen sikre tests er findes endnu eller?? - han har en E6600 kun, så måske sku han finde en brugt Q9650 og smide i og nøjes med 5850

ps. money is no object 😉 men han gider nok ikke bruge tid på at skifte bundkort osv... så i7 - i5 er lidt out of bounds. og amd og mac skal ikke nævnes i denne tråd hehe, sku jeg hilse og sige 😛

5870 skulle efter sigende placere sig tæt op ad ydelsen på et GTX295, så..

#1 hej tom, super, takker - ja det er jo lidt skuffende egentligt eller? 😀

med de sindssyge ramspecs og endelig 512mbit bus så burde AMD ha lavet et 8800-agtigt kort (som er udråbt til dette årtis kort)

Regn med der er blevet snydt lidt med de resultater, så er du ihvertfald på den sikre side.... så sig at et hd5870 ligger et lille stykke under gtx295 og over gtx285.... Så ved du cirka hvordan feltet ligger.... tror selv at hd5850 bliver rigtigt interresant i CF :yes:

#2 mhhnarh, mere skuffende er, at Nvidia (igen igen) benytter GDDR3 - denne gang til GT300.. de må da snart forstå, at et skift til GDDR5 er på tide :'-(

De har nok købt en helt masse billigt på udsalg da ATI skiftede over til GDDR5 😀

#2 rygterne siger altså 256bit rambus og 165-170gb/sec brandwith, thx to 4000+ mhz GDDR5 clocked speeds mener det er omkring 4200 på HD5850 og endnu mer på 5870.

men hvis et HD5870 1gb kort yder som et GTX295 så er det da ikke dårligt, GTX295 er jo trods alt et rimeligt godt dobbelt Gpu card.

men alt sammen er stadig rygter. jeg tror dog at Det nye ATI HD5870 SIX kommer til at rykke rimeligt godt , specielt hvis man tænker i 2-3 ways crossfire baner.

og ellers var der jo os på et tidspungt snak om et HD5870 X4 kort. 😛

Ja hd5870six bliver et hidsigt kort, men det er trods alt også en helt anden gpu der sidder i 😉

Og prisen bliver ikk hver mands eje :no:

Der er ikke den store forskel på et 8800GTX og et 260GTX, og hvis tom siger at et 5870 skulle yde som et 295GTX, så er det vel en fordobling.

#7 enig.

Det kan næsten ikke være andet end 256 bit givet båndbredden (4870 har 116 GB/s). Og det er iøvrigt 5.25 GHz: Se:

#11 der er NDA/udgivelse den 22-23 september , men forvent 1-2 måneder efter før de er på stock i danske IT butikker/online shops, så går du nok ikke helt galt i byen.

tror selv på at man ka købe dem ved oc.uk + div andre steder 2-4 uger efter NDAbrud/lunch. men igen det er så forskelligt fra gang til gang.

DDR-5 er ikke bedre end DDR-1. snarere tværtimod. Jo højere tal, jo "billigere" er de at producere per hz og jo højere frekvens kan de nå.

DDR-5 har meget højere latency(forsinkelse), hvilket kan vejes op af den højere frekvens. Men der skal oftest meget til, og det ses oftest at sidste generation af DDR-ram er hurtigere end den nyeste, trods højere frekvenser.

at nVidia vælger DDR3 er kun til vores fordel. Det gør at de vælger nogle ram der arbejder med en meget lavere frekvens, bliver mindre varme, osv. Så vælger man istedet 512bit ram-bus istedet for 256. Hvilket i sidste ende vil lamme tæve DDR5 ved den dobbelte frekvens. 🙂

At vade rundt i DDR-navnene og undre sig over hvorfor at nogle er hurtigere end andre er flueknepperi. i sidste ende koster det garanteret det samme for producenter, og de handler oftest om hvem der enten falder over billige ram-kurser. At nvidia f.eks. var de første til at benytte DDR2 sammen med højere rampriser og et overlegent grafikkort fra ATi med DDR-ram gjorde jo ikke at nvidia's kort var bedst. (FX5800 og Radeon9700) nVidia lærte lynhurtigt af fejlen og kom med et revideret grafikkort med DDR-ram og højere bus, der nu var konkurrencedygtig og på prisen.

Jeg er enig med dig i, at ydelsen mellem DDR3 og DDR5 ikke er særlig stor, når Nvidia kompenserer med en større bus/båndbredde - men når begge producenter er ved at nærme sig en identisk bus, kræver det heller ikke ligefrem en regnemaskine for at se hvem der får snuden foran.

Flueknepper? Tak da ❤

DDR / GDDR, der er væsenlig forskel 🤡

#12 jeg forstår absolut ikke hvad som står... NDA, None disclosure agreement brud lunch, hvad????

Angående ATI's kommende kort er der såvidt mig bekendt kun ét sted externt fra ATI som rent faktisk har kortet... (dog 1 mdr gammel info)
Altså er det meget svært at sige noget håndfast om den kommende generation.

Nedenstående er eksempel på en NDA; (justeret selvfølgelig)

#19 du forstår jo nada.

det jeg mente var at NDA´en ophørte den 22-23´ende.
altså at dem der havde skrevet under på det du så fint viser, kunne fremlægge nogle test og billeder lovligt fra den 22-23 ´edne + websides ku vise dem i webshops fra den dato.

ja det skrev jeg ikke, men regnede ikke med at nogle var (Dumme) nok til ikke at fatte det.

og til en anden gang så drop dog alt det spam og blær.
