GDDR5 - izo ziri pa khadi kanema? m'badwo wachisanu wa DDR SDRAM kukumbukira

Amene poyamba anayamba kuika pamodzi PC anu, kapena kumvetsa izo internally, kuyamba kukumana ndi zambiri mawu zosokoneza. Pamene tikutsegula chivundikiro computer, ife zambiri za mawaya, mbale, mafani limalephera kutentha, etc. Kuti asamve kamodzinso mbuye ndi kuti funsani abwenzi, losavuta kumvetsa.

Today tikambirana zoterezi mfundo zosangalatsa, monga GDDR5. Kuti, ambiri sakudziwa, ena amaganiza zina zambiri ndi kumvetsa. Pofuna kusokoneza owerenga, m'pofunika kunena mwakamodzi GDDR5 kuti - ndi kukumbukira. Chifukwa adzaupereka ndi kumene ali, ife tidzadziwa zochuluka.

Video kukumbukira

Osati kuti dambo pa munthu wosadziwa kamodzi gulu la mawu, ndi bwino kupita ndi linzake. Ife tonse tikudziwa za mavabodi, amene aikidwa mu nkhani PC. Adzakhala olumikizidwa kwa purosesa, ndi magetsi, khadi video, RAM ndi zinthu zina. Kupatula chakuti pali chikumbukiro dongosolo, komanso ali ndi lingaliro lofanana, ndi khadi kanema.

Motero, pali mawu akuti - kanema kukumbukira. Ndipotu, ndi mofanana RAM, koma udindo mwachindunji kusungiramo gawo la mfundo zimene zili zofunika kubereka chifanizirocho chophimba. Mosiyana pokumbukira dongosolo lonse, ndi ntchito ziri kwa kanema. Choncho, tchipisi kanema kukumbukira anayikidwa pa khadi zithunzi.

kuyambira

Yambani womdziwa wanu ndi RAM osiyana m'pofunika ndi kusintha choyamba. Mawonekedwe wamkulu wa "RAM" imatengedwa kuti kukumbukira DDR. Tsopano, mwinamwake, sikutheka kupeza mavabodi ndi mtundu uwu. Opaleshoni voteji anali 2.5 volts. Kumene, kuyang'ana mmbuyo pa mitundu yonse kale, tikhoza kunena kuti DDR kukumbukira kunyeketsa magetsi ambiri.

mitundu

Tikalibe kuphunzila za zimene zili GDDR5 zithunzi khadi, m'pofunika kumvetsa zinthu zosiyanasiyana. Mitundu kukumbukira nthawi zonse, zinali zosawerengeka. Fotokozani lililonse sizimatanthauza, kotero muyenera usapite ku nsonga.

Ambiri, kukumbukira kupeza mwachisawawa DRAM dzina lakuti. Choyamba zinadziwika kwa dziko pa Nkhondo Yachiwiri ya World. Koma mawonetseredwe yake yamakono zinaoneka mu 1966. Long nthawi kutukula ndi opanga anayesetsa kusintha kukumbukira. Imodzi mwa mitundu loyamba anakhala PM DRAM kumayambiriro 90 ntchentche Mu zaka zapitazo.

Koma kutukula nayo nthawi zonse kuonjezera liwiro ndi buku la "RAM". DDR SDRAM - Pambuyo zoyesayesa asanu, mtundu watsopano limapezeka pa msika. Iye anasintha m'mabaibulo yapita Kupititsa patsogolo Data Mlingo (kawiri). Mtundu koyamba anaika zithunzi makadi. M'kupita kwa nthawi, kutukula kugwiritsa ntchito RAM ndipo chipset.

maziko

Akukhulupirira kuti GDDR5 anaonekera kuyamika DDR SDRAM. Izi Baibulo chachisanu imene kwaiye chifukwa ntchito. softs izi zimafunikira mkulu bandiwifi. Kuloŵedwa m'malo mwa njirayi wakhala wachinayi m'badwo kukumbukira. Onse zochokera DDR3. Kulankhula njira wakhala kawiri, kumeneko buffers m'lifupi 8 Akamva.

N'zochititsa chidwi kuti mtundu uwu wa ntchito zambiri opanga. Choncho kafukufuku "malekezero" anali Hynix, Qimonda, Samsung ndi JEDEC. anadabwa chinali chifukwa chakuti nawo ntchito limodzi ndi kampani AMD. Panapita nthawi yaitali kwambiri, ndipo kuyambira pa chiyambi mpaka kumapeto anatenga zaka zitatu. Pa nthawi imeneyi kutukula anatha iyende kwambiri.

Ndiye ife kuphunzira zambiri za GDDR5, chimene chiri ndi zomwe. Koma si wina aliyense akhoza kugwiritsa ntchito kukumbukira ichi monga zomasulira ake adakali kupanga. Chiyambireni tchipisi ake njira akugwira ntchito voteji otsika 1.5 V, ndi osalimba anali 0.5-2 GB. pafupipafupi wawo akayamba 4000 MHz, ndipo patapita kanthawi anakwanitsa kulera chithunzi ichi mpaka 7000 MHz.

Iye kale anaonekera pa osalimba a 1 Gbit Chip mu 2009, patatha chaka - pa kachulukidwe wa 2 Gbps. Njira masika wakhala popangidwa ndi 50 nm ndondomeko luso. Ndi chiyambi cha 2015 chitukuko kwachititsa kwambiri. Chip kachulukidwe anafika 8 Gbps, ndi yonama ndondomeko ntchito kwa 20 nm. Izi zimaphwanya mbiri anabwera pansi pa utsogoleri wa kampani Korea Samsung.

mfundo

Kuti mudziwe zambiri zokhudza wa GDDR5, kuti n'chifukwa chake tiyenera kukumbukira ichi, n'kofunika kuganizira makhalidwe omwe tsopano ntchito ndi opanga onse. Monga chikuonekera mu mutu wa kalata «G» ndi udindo mfundo Zojambula. Ndiko kuti, mtundu wa kukumbukira zingamuthandize khadi kanema.

GDDR5 wamasulidwa pansi standardization. Motsogoleredwa zomangamanga 8n, ndi kasinthidwe wa mphamvu mawonekedwe, komanso zipangizo zamakono bwino ntchito. Chip wina ali ndi m'lifupi 32 Akamva ndi thupi anali kulankhula 170. Njira zamakono ndi 40 nm.

pafupipafupi zingadziŵike mwa magawo awiri. Ngati woyamba chosonyeza 1250 MHz, wachiwiri udzakhala wofanana 2500 MHz, mwachitsanzo kuwirikiza kawiri. Opanga zambiri amasonyeza mafurikwense osiyana, koma mtokoma yofanana.

The mwayi waukulu mumaganiza wakhala kusintha matulukidwe. Mosiyana ndi wachitatu m'badwo VRAM wachisanu anali kuthamanga pa pang'ono basi lonse 128/256. M'njira zambiri anathandiza ena zizindikiro. Choncho, 512 pang'ono GDDR3 ntchito matayala. Izi chithunzi kuchuluka Chip kukula, ma CD ake, motero mtengo wa chitsanzo lonse. Video khadi ndi mtundu uwu kudyedwa ndi kuchuluka wamkulu wa mphamvu.

kumayambiriro

Tsopano ife tikudziwa wa GDDR5, kuti ndi kanema kukumbukira, ntchito ya opanga kutsogolera. N'zosadabwitsa chitsanzo choyamba cha khadi kanema anaonekera mu 2008, ndi ku, AMD. Anakhala ATI Radeon HD 4870. inali kuperekedwa mu Mabaibulo awiri, ankasiyana buku la 512 MB ndi 1 GB.

Panali zitsanzo za NVIDIA Geforce. GDDR5 yomweyo kuonekera mu mndandanda wa makadi, mwa amene :. GTX 550, ndi GTX 560, ndi GTX 580, ndi GTX 590, ndi GTX 660, ndi GTX 680, etc. Komanso, mtundu uwu wa kukumbukira tsopano ikupezeka mu Baibulo chachinayi cha PlayStation kutonthoza. Pa nthawi yomweyo anaikidwa kumeneko monga RAM a.

anapezazo

Kufotokoza onse pamwamba, ndikofunika kuzindikira kuti nthawi zambiri zadutsa RAM kuyambira anaonekera. Video kukumbukira ali kusanduka anapanga. Tsopano m'badwo wachisanu analibe liwiro kwambiri kwa onse. Ndi posachedwapa anadzakhala mtundu wina - GDDR5X. Iye ndi kawiri mofulumira. Komabe, ndiyo anafuna GDDR5 pamtima, osati monga zikuluzikulu za khadi kanema, komanso osiyana tchipisi RAM.

Tsopano kuopseza waukulu, umene n'zotheka kuti kutha kwa mtundu uwu wa kukumbukira ndi msika ndi kukumbukira ali kwina kukhala ndi kusintha. Komanso, mpaka iwo alibe anakwanitsa kuthetsa vuto ndi mowa mkulu mphamvu. Ngakhale mfundo m'mabaibulo loyamba laling'ono kwambiri, koma palibe iko sikumaŵathetsa. Komanso anapatsidwa azimuth posachedwapa kwa overclocking, vuto ndi mowa mkulu mphamvu msanga komanso supercedes.
