Radeon HD 7870: kupenda khadi kanema

Radeon HD 7870 - zithunzi khadi la anthu opeza, amene anaonekera pa maalumali mu 2012. Iye sanathe kuposa Anzawo zodula, koma kwambiri outperforms zitsanzo m'mbuyomu. Machesi kwa AMD Radeon HD 7870 anali GeForce GTX 570. The accelerator linatulutsidwa miyezi ingapo HD 7970, amene kudabwa mafani zambiri kampani. Nova amayembekezeka kupeza masanjidwe atsopano - Kumwera Islands. Apa iye anakhala mmodzi wa oimira awiri zitsanzo zilipo ndi ntchito zabwino ndi dongosolo wamakhalidwe kuzirala. Komanso, AMD Radeon HD 7870, mtengowu $ 350, anapatsidwa zomangamanga kusinthidwa.

Kenaka zida

Khadi amabwera mu bokosi laling'ono chidapangidwa kuchokera ku katoni glossy. Pa mbali yakutsogolo kwa wosuta nawo ndi mtundu woipa wa wokwera pa kavalo kwambiri kukalipa. Apa mutha kuona dzina chitsanzo ndi mfundo zazikulu zimene kudabwa Radeon HD 7870.

Zambiri kumbali kumbuyo. Apa, wosuta akhoza kuphunzira makhalidwe a accelerator lapansi. Bokosi kumapereka chithunzi chabwino, koma kusuntha kumaliza.

Kuwonjezera video, phukusi kumaphatikizapo:

• ya milozo;
• CD-ROM ndi madalaivala;
• anapereka kwa adaputala azamagetsi;
• PCI-E mphamvu chingwe;
• CrossFire mlatho.

Ambiri, zida Radeon HD 7870 si bwino kapena choipa koposa anapereka opanga ena. Ntchito yachibadwa si koyenera kuti adzathe kugula mbali zawo, kuti ndi osangalala. adaputala azamagetsi zina akhoza kukhala zofunika ena owerenga. Zina zonse zokwanira kuti amapereka ATI.

maonekedwe

Pomwepo chidwi cha polumikizira angapo kulumikiza chipangizo aliyense mosavuta. Zinthu zazikulu ndi soldered ku dera bolodi amasindikizidwa wakuda. Nkhope ya GPU ndi kuoneka bwino. Mwa njira, khadi akhoza ntchito mu tandem. Komabe, tandem akhoza zigwirizana zithunzi awiri okha mitima. Choncho, opanga masewera sadzakhala kulenga "chilombo", umene unapereka mafelemu miliyoni pa wachiwiri pa zoikamo pazipita zithunzi.

Komanso, bolodi mwaukhondo anakonza zigawo kukumbukira ndi ogwiritsa mabowo angapo dongosolo chachikulu kuzirala. Mfundo maonekedwe a khadi akhoza kudabwa koma kuti novice amene poyamba akuona chipangizo ofanana. Unakwaniritsa onse khalidwe wokongola mkulu ndi mmene awa makadi zithunzi.

makhalidwe a

Zochokera zithunzi khadi pa zithunzi pakati Radeon HD 7870. Amathandiza DirectX 11,1, ndi OpenGL 4.2, kuti kale anawonjezera chidaliro. Iwo amamuonera khamu la umisiri kampani, monga CrossFireX. Ndi iwo, wosuta adzatha kutenga kuti ntchito accelerator pa mphamvu zonse. Phata ukugwira ntchito pa wotchi pafupipafupi 1100 MHz. Kusamutsa deta ntchito mwachilungamo latsopano 256-bit basi.

zigawo Video kukumbukira amakonzedwa ndi Hynix. The accelerator ali 2 GB kukumbukira, ndiwo mtundu wa GDDR5. Kukumbukira akuthamanga pa pafupipafupi bwino 5000 MHz. Izi Kumkwanira ngakhale masewera ambiri panopa chaka. Komabe, si onse anathawa pa zoikamo pazipita zithunzi.

Khadi kanema angathe kusonyeza chithunzi ndi kusamvana pazipita 4096x2160 pixels. Today makhalidwe kusiya kwambiri wolakalakika, koma pa otsika bajeti Radeon HD 7870 adzakhala njira yabwino kugula. Molumikizana ndi purosesa wabwino, angathe ntchito zodabwitsa pouza mapulogalamu.

Kachitidwe yozizira ndi mowa mphamvu

Ntchito wapawiri-kagawo dongosolo kuzirala. Polingalira za makhalidwe avareji Mlengi sanali kukopera accelerator mipata atatu omwe amagwiritsidwa ntchito mu zitsanzo amphamvu kwambiri ndi yokwera mtengo.

Yozizira ndi dongosolo mwachilungamo lalikulu lomwe lili kupuma awiri. Pakuti khadi kanema, ichi "yeniyeni" amamangiriridwa akapichi 4 okha. Mkati pali mipope kutentha atatu kuti mwachindunji kulimbana ndi kutentha kufalitsa chivindikiro. Palinso anamanga Redieta yaing'ono zotayidwa. Monga tanenera kale, kwa kuwomba zimakupiza kudzakhalire tiwiri pa mfundo zomwe deta palibe.

Mu osagwira khadi mode amadya 32 W mphamvu. Mowa ukuwonjezeka kwambiri poyamba udzafunidwa kapena masewera. Mwachitsanzo Crysis 2 (zithunzi pazipita ndi FullHD-kusamvana kolowera) mowa mphamvu chinalembedwa m'dera la 140 W.

Video khadi ntchito wokongola chete. Mu mode osagwira yozizira pafupifupi inaudible phokoso. Komabe, pansi pa katundu mlingo phokoso ukuwonjezeka kwambiri, Radeon HD 7870 mu mode izi kuposa zitsanzo ngakhale amphamvu kwambiri.
