Ati Radeon HD 4800 Series: te whakaahuatanga o te āhuatanga hoahoanga o te raupapa kāri ataata tawhito

Ati Radeon HD 4800 Series именуется классически. Kei te tuku Series Ati Radeon HD 4800 Raupapa ki rite te classic. Ko te mati tuatahi tohu te whakatupuranga o te whāurutau. Hoki te whānau tuarua i roto i te piringa. Ko te rua whakamutunga tohu te tauira motuhake. I te tīmatanga, tīmata te utu o ngā kāri ataata o tenei whakatupuranga ki te tohu o 5,000 moni. Na kua mutu e te tuku o enei whakaaro, ka taea e te mākete tuarua whakahere taua whakaaro mo te utu o 1000 moni.

matua

te ingoa i te ataata i RV770. Kei roto te reira i neke atu i te 900 miriona transistors. O te akoranga, ko te tino he rota, engari e kore te whakaatu hoki tenei. Heoi, ka whakaiti i te matatau hangarau tukanga 55-nm te utu o to ratou take, me te ki whiua te whakataetae mo te roa.

ATI Radeon HD 4800 Series довольно сильно снижены по сравнению с ядром предыдущего поколения. Me mea e ahau e te auautanga Ati o te GPU te Radeon HD 4800 te heke rawa Rangatū whakaritea ki te whakatupuranga pūkaha o mua. Heoi, me taurite te nui haere te kaha o pūtukatuka kakano iarere GPU drawback.

tika te reira i tokanga makehe o mahara GDDR5. Ko tōna whakamahi i hanga reira taea ki te whakaara i te pae o te hōkaiipurangi pahi, kahore te whakanui ake tona hohonu moka. O te akoranga, te utu o GDDR5 nui, engari whai reira he tūranga iti, rite te whakaritenga māmā o nga whakaaro katoa i runga i te poari.

Ko te kāri wahi ataata tino raruraru ki tau rangatū 3 - pūtukatuka kakano. Te whakanui ake ratou tokomaha ki 40 i tukuna mo tatou ki te whakaoti i te raruraru matua.

whakapaitanga ALU

видеокарта ATI Radeon HD 4800 Series очень зависима от уровня оптимизации кода шейдеров в 3D-программе. Ati Radeon HD 4800 kāri whakairoiro Series, tetahi tino ti'aturi i runga i te taumata o te waehere shader arotautanga i roto i 3D-hōtaka. Heoi, kei te rite rawa te raupapa o whāurutau ki e waru rau ALU, a ki runga ki ia matua o te pūtukatuka he reira i roto i te Kaiwhakahaere Tūmahi ki arotau aunoa. I roto i te kino rawa take, ka tukatuka te wā kotahi te waehere i roto i te ALU 160. Ki te utaina ia wae rorohiko te ki te mana rorohiko mōrahi ka kia rite ki te kotahi teraflop. He rite ki NVIDIA tino nui whakatupuranga iwa o tenei ahua.

Whakamutunga architecture mowhiti

ATI Radeon HD 4800 Series под микроскопом, можно увидеть, что в общем сохранены все технические особенности предыдущего поколения ядра. Whakaaro i te kāri whakairoiro pūtukatuka Ati Radeon HD 4800 Raupapa i raro i te karu, ka taea e kite koe i e, i roto i puritia whānui nga āhuatanga hangarau katoa o te whakatupuranga matua o mua. Na, Heoi, hoahoanga kore-annular.

Ko te pūmana mahara integrated atanga e mahi bidirectionally. Poraka e kore e e hiahia te uru tere ki nga tohutohu e kua kei huri noa te matua. I tua atu, kei te pūtukatuka te tata te pana, hono reira whakaaro e kore e taua hōkaiipurangi tino. Ki te taea e te tōtika o te āhuatanga matua o te whakatupuranga o mua tae te tohu o 85%, kua tukua nga whakapainga ki te kawe i te reira ki te mōrahi mahi. mea tohunga a Ati e 40% pai atu te wae rorohiko riro.

pūtukatuka pānui

Ka taea te huaina Kaiwhakahaere Tūmahi he pūrere matua o tetahi pūtukatuka whakairoiro. Tona mahi ko te tohanga pai o ngā rauemi. I roto i tenei take, kia utaina katoa o te pata ōrite. Ki te tutaki tenei huru te, ka kia whakanui ake te mahi.

количество блоков для хранения и обработки кода увеличилось. I roto i te putanga Ati Radeon HD 4800 maha Series o poraka mo rokiroki waehere me te tukatuka nui haere. Kua riro hoki te reira i nui me te maha o SIMD-ngohi. No te mea o tenei, e kore e inaianei mahi ia ngohi i roto i wehe, e taea te whakawhiti raraunga ki te tika. I tua atu, i te arotautanga o hātepe me waiho i raro ki te Kaiwhakahaere Tūmahi.

wae kakano

I roto i te kāri ataata toru o whakatupuranga i 16 anake wae kakano, he tino kore e nui hoki te nuinga o 3D-tono e. Ai kiia ia TMU mo anake wae filtration kotahi. Ko tenei rawa kite ina te ka tātari anisotropic, a faaohipa i te reira mau vahi atoa.

Kua tangohia e te ngā ki pūkete te wheako o ngā hapa o mua. Na TMU i roto i ia kōwae ko 16 wae, e mahi ana kakano tauira, me te tātari i roto i te 4 me te whakatutuki poraka. Honoa ki te nui haere hōkaiipurangi o TMU mahi o tenei tūemi kua nui haere e 2.5 wā.

Kōwae, me te rite i roto i pakeke whāurutau whakaatu e ngā ki 4. Heoi, e tika ana ki te arotautanga o te maha o transistors heke konei.

keteroki

характеристики которой заметно выросли по сравнению с младшими адаптерами, получила новую систему кэшей. Ati Radeon HD 4800 kāri whakairoiro Rangatū, te āhuatanga o e mārika i fakatupulaki a whakaritea ki whāurutau teina, ka he pūnaha keteroki hou. Na, ko te utu o te raraunga ki te keteroki taumata tuatahi puta i pā ana ki 480 GB / s, te tuarua - te 380 GB / s. I tua atu, kei te tāuta katoa te matua SIMD inaianei ona ake mahara, e taea ai e koe te mahi i te wa ano he tokomaha nui o ngā mōhiohio.

āhuatanga hou

Haunga te auaha taketake, ka kore te kino e tuhia me te iti. Kua whakatakotoria e kāri katoa i roto i te raupapa HD 4800 ratou pūmana Realtek, e taea ai e koe te mahi tukutahi ki waru takere. I roto i tenei take, te Auaumoka putanga mōrahi he tika i runga i 6 Mb / s. Ko te auau here tīpako runga i 192 kHz.

He tino nui mo te hunga e e haere ana ki te hono ki te pūnaha rongorau rorohiko āhuatanga arā atu anō. о которой и без того лестны производителю, из-за описанных выше особенностей получила в свою армию фанатов еще и пользователей, не интересующихся компьютерными играми. Ati Radeon HD 4800 raupapa, whakaahuatia ana i runga i nga arotake o e patipati kua kaihanga, no te mea o te āhuatanga i roto i tona ope o te pā, me te ara kaiwhakamahi kore e hiahia i roto i ngā kēmu rorohiko nei.

Hanga-i roto i te pūwetewaehere ataata te ao, ko te kore anake ngāwari ki te akakoromaki i te tākaro-teitei ataata, engari ka taea e hoki te wā kotahi whakaatu reira i runga i te aroturuki e rua rerekē. Ko te kupu hoki ia pūrere huaputa taea huaputa tohu rerekē.
