GTX 1080: cov ntawv qhia kev siv video, kev txheeb xyuas thiab kev xeem

Lub koob taw cim graphics accelerator nrog lub siab tshaj plaws nyob rau hauv ib leeg-chip kev ua tau zoo yog lub GTX 1080. Cov yam ntxwv ntawm cov khoom no yog tiag tiag muaj nqis, thiab nws cov peev xwm kiag li tsis muaj caij nyoog rau competitors. Tau kawg, daim video no yog yav tom ntej, thiab nws yuav yog qhov tseem ceeb tshaj li ib xyoos.

Nyob rau lub khw muag khoom yog qhov video daim hom phiaj no?

Raws li nws tau hais ua ntej lawm, tus GTX 1080 yog tswj hwm ntawm qhov kev ua si ntawm qhov kev ua kom thaij duab zoo tshaj plaws. Cov theem ntawm kev ua tau zoo nyob rau hauv cov ntaub ntawv no yog siab kawg tias txawm tias cov khoom saum toj kawg nkaus ntawm lub dhau los tiam tsis tuaj yeem tsim nyog sib txig rau daim npav no. Ntawm lwm cov nta ntawm no accelerator yog kev them nyiaj yug rau virtual kev muaj tiag lub nruab thiab HDR-saib. Thiab yog tias thawj pab pawg ntawm cov cuab yeej muaj peev xwm twb pom nyob rau hauv lub txee ntawm khw muag khoom thiab, yog tias tsim nyog, yuav, ces HDR tus saib xyuas tseem tsis tau muaj. Lawv tshaj tawm yog teem rau lub quarter thib rau xyoo 2017. Lwm qhov chaw uas zoo li ib yam khoom yuav pom nws daim ntawv thov yog 4K saib.

Yog li ntawd, nws yuav tsum tau sau tseg tias qhov no accelerator yog ua ntej ntawm lub sij hawm thiab muaj kev ua tau zoo heev margin. Nws tsis tseem yuav tseem ceeb rau ib lub sijhawm ntev, thiab ntau tshaj ib tiam ntawm cov duab adapters yuav sib npaug zos rau nws.

Pob Txheem

Ib lub nra hnyav rau ib qho khoom muag los ntawm GTX 1080. Cov yam ntxwv ua rau kom rov qab xav dua. Tab sis lub logic ntawm lub tuam txhab-tsim tawm nyob rau hauv no qhov teeb meem yog tseem to taub. Daim video card tsis pheej yig, thiab yog tias tsim nyog nws tus tswv yuav tau ntxiv tus nqi tsawg tsawg tiv thaiv tus nqi ntawm tus tsuj roj rau kev yuav khoom ntawm ib qho los yog lwm yam khoom ntxiv. Txwv tsis pub, lub pob ntawm daim video no yog raws li nram no:

• Lub adapter nws tus kheej.
• Phau ntawv qhia ntau yam, ntxiv los ntawm daim ntawv them nyiaj guaranty.
• Disk nrog ib co software: hlauv taws xob, tsav tsheb thiab xeem software.

Khoom Specifications

Thawj qhov tseem ceeb ntawm qhov kev lag luam no yog qhov txheej txheem tsim los ntawm cov khoom siv hluav taws xob uas yog semiconductor. Nws sib raug rau kev kam rau siab ntawm 16 nm. Tag nrho cov thawj ntawm cov khoom no tau ua ntawm 28 nm, thiab qhov video video nti yog revolutionary.

Lub npe lub npe rau cov khoom siv rau hauv cov khoom no yog Pascal, thiab lub nti yog sau ua GP104. Tus naj npawb ntawm transistors nyob rau hauv cov ntaub ntawv no yog 7.2 billion. Cov kev khiav hauj lwm zaus ntau ntawm cov duab nti cov duab ntawm 1607 MHz mus txog 1733 MHz. Raws nraim hauv cov duab no muaj xws li shader units, muaj pes tsawg leej twg hauv qhov no yog 2560. Raws li qhov ntsuas no, qhov tam sim no flagship nws ua tsis tau zoo rau nws cov thawjcuam.

Thaum lub GTX 980 tus xov tooj yog sib npaug zos rau 2816, thaum lub Titan - 3072. Tab sis lub zaus mis tau ntau coj, thiab raws li ib tug tshwm sim, txo tus naj npawb ntawm shader units yog ntau tshaj li compensated rau lawv ntau dua kev khiav hauj lwm ntau zaus. Tus TMUs rau txhua qhov kav dej yog 160, thiab ROP-64 thaiv. Cov duab adapter nws tus kheej yog taw rau qhov kev teeb tsa hauv PCI-Express qhov 3.0 thiab txhawb Direct X 12.

Graphics accelerator nco

Ib tug tshiab hom RAM graphics nco graphics card siv cov GeForce lub GTX 1080. Cov yam ntxwv ntawm nws tiag tiag impressive. Lub npe ntawm no RAM yog GDDR5X. Yog hais tias yav dhau los hom RAM GDDR5 feem ntau zaus yog 7 GHz, ces qhov no tus nqi no twb tau sib npaug zos rau 10 GHz. Tus nqi ntawm lub cim ntawm qhov kev ntsuam xyuas no yog 8 GB, thiab qhov no yog qhov txaus rau qhov kev muaj tiag, HDR-saib lossis 4K-saib.

Qhov loj ntawm lub tsheb npav nco yog 256 khoom, thiab raws li qhov ntsuas no GTX 1080 poob rau nws cov neeg ua ntej nyob rau hauv lub ntsej muag ntawm GTX 980 thiab TITAN (cov accelerators tau muaj peev npav npav RAM ntawm 384 khoom). Tab sis qhov kev txhim kho optimization ntawm RAM controllers, ntau zaus ntawm RAM thiab cov siab heev tshuab ntawm compression ntawm cov ntaub ntawv ua nws ua tau yooj yim bypass lawv cov predecessors rau cov hero ntawm qhov kev ntsuam xyuas thiab kom compensate rau txo ntsis qhov tob ntawm nco lub chips.

Kev tshaj tawm thiab kev nce qib

Tsis zoo los ntawm overclocking NVidia GTX 1080. Cov yam ntxwv ntawm cov khoom no qhia tau tias lub hauv paus zaus ntawm tus nti yog sib npaug rau 1607-1733 MHz, thiab RAM - 10 GHz. Cov kev tshwm sim muaj nyob hauv cov kev sib tw overclocker qhia tias xyaum, nws tsis yooj yim los ua kom pom qhov tseem ceeb dua qub rau tus qauv processor thiab RAM, feem ntau, mus rau 1770-2000 MHz thiab 11.5 GHz. Qhov nruab nrab, qhov no tso cai rau koj tau txais ib qho ntxiv 30% rau kev ceev. Tam sim no lub overclocking ntawm xws li ib yam khoom yog sob rau yog vim li cas thiab thiaj li nws ntau theem ntawm kev ua tau zoo. Tab sis tom qab plaub xyoos, cov tswv ntawm lub tub ceev xwm tej zaum yuav tau mus rau qhov chaw ua haujlwm.

Analogues

Cov yam ntxwv ntawm GTX 1080, raws li tau sau tseg yav dhau los, yog qhov zoo dua li cov cim dhau los. Qhov nruab nrab, nws yog 20% sai dua lub GTX 980 thiab TITAN. Txawm tias sib cais los ntawm AMD flagship hauv lub ntsej muag Fury X, uas yog nyob rau ntawm 30 mus rau 40%. Rau hnub tim, qhov khoom tshwm sim ntawm NVidia tsis muaj cov neeg sib tw, thiab thaum lawv tshwm sim - nws tsis paub.

Tus kheej ntaus tswv yim ntawm cov lej xaib tsuas yog nthuav tawm, thiab nws cov kev hloov tshiab hauv lub neej yav tom ntej yuav tsis tuaj. Qhov tshij, lub cim tshiab ntawm cov yeeb yaj duab AMD zoo tshaj plaws yuav raug tso tawm hauv thawj ib nrab ntawm xyoo 2017. Yog li ntawd, rau ib lub sij hawm ntev, tus hero ntawm no tsab xov xwm yuav tsis muaj kev sib txeeb tseem ceeb.

Kev sim

Yuav luag txhua daim ntawv sau npe muaj 20-30% kom zoo tshaj qhov nws ze tshaj plaws Geitorce GTX 1080. Cov yam ntxwv ntawm tus nti nws tus kheej txawm taw tes rau qhov no. Qhov khoom ua si nkaus xwb uas tus tshiab flagship yuav tsis pom ib qho kev tshwm sim hauv cov cim suab ntau thiab qhov tso tawm ntawm 2K duab nrog ULTRA nqis yog Quantum So. FPS nyob rau hauv nws yog nyob rau hauv qhov ntau los ntawm 22.4 mus rau 25.3. Tib lub sij hawm, AMD tus flagship hauv lub ntsej muag Fury X muaj ntau yam ntawm FPS los ntawm 22.5 txog 26.1.

Overclocking tus tshiab flagship tso cai rau txawm bypass AMD qhov kev txiav txim siab nyob rau hauv hom tsis tu ncua nrog FPS 23.4 - 26.4. Tab sis qhov no, feem ntau, qhov kev zov me nyuam txoj kev kawm zoo rau AMD cov kev daws, thiab qhov kom zoo dua yog tau los ntawm lawv. Rau kev sib piv, zoo ib yam ntawm cov zis duab thiab thaum Direct X 12 yog tshuab ua si, qhov Hitman GTX 1080 muaj peev xwm ua tau 42.1 - 49.4 fps, thiab Fury X - 39.8 - 47.4. Thiab qhov kev ua si yog optimized rau cov khoom AMD, tab sis qhov kom zoo dua, albeit insignificant, yog nyob rau sab ntawm tus tshiab flagship ntawm Nvidia. Nyob rau hauv lwm yam, flagship graphics card ntawm lub dhau los tiam no hopelessly poob rau lub hero ntawm no rov los saib dua. Piv txwv, GTX 1080 nyob rau hauv GTA V kev ua si hauv 2K hom thiab nrog Direct X 11 yuav muab FPS ntawm 38 - 67.3, thiab nws cov neeg ua ntej GTX 980 thiab Fury X, feem ntau yog 31.4 - 54.4 thiab 26.4 - 44.6. Thiab nyob rau hauv feem ntau niaj hnub gaming daim ntaub ntawv, qhov no yog qhov teeb meem uas tau pom.

Nqe thiab kev txheeb xyuas

Qhov kev txiav txim ntawm 50.000 rubles yog tam sim no NVidia GeForce GTX 1080. Cov yam ntxwv ntawm nws yog tib yam nkaus li cov nqi no. Nws muaj peev xwm daws tau txhua qhov teeb meem, thiab nws cov tsis muaj peev xwm muab cov khoom pov thawj txaus tsim nyog rau ntau xyoo tom ntej. Qhov kev pom zoo ntxiv yog ib qho kev tawm tswv yim ntau los ntawm cov tswv cuab ntawm cov khoom no. Tseem mus rau qhov zoo ntawm tus tsuj roj yog qhov zoo tshaj plaws overclocking tej zaum.

Ntsiab lus

Tiag tiag tiag revolutionary graphics daws tau lub GTX 1080. Nta, xws li cov theem ceev, tso cai rau daim npav no yam tsis muaj teeb meem los daws cov hauj lwm. Thiab daim duab no yuav muab khaws cia rau peb xyoos tom ntej. Tsis tas li, cov ntsiab lus tseem ceeb ntawm cov khoom no muaj xws li kev them nyiaj yug rau 4K-saib thiab cov TV, tseem tsis tau tso tawm HDR-saib thiab kev siv cuab yeej virtual. Tag nrho cov no nyob rau hauv tag nrho tso cai rau nco ntsoov tias NVidia tau tso tawm qhov zoo tshaj plaws video card nyob rau hauv ib leeg-nti kev kawm rau hnub tim.
