AMD vs Nvidia GPUs: Ndeipi Yakanakira Iwe?

key takeaway

Kuziva mutsauko uripo pakati pe AMD neNvidia GPU kiyi pakuita sarudzo yakanaka.

Chiratidzo chega chega chinokunda munzvimbo dzakaita sekutamba kwemitambo uye ray tracing tech.

AMD neNvidia's AI machipi anoita mutsauko mukuru mumabatiro atinoita zvinhu.

Mashandisiro anoita GPU simba uye kugara achitonhorera kwakakosha.

Maonerwo anoitwa brand pamusika uye mitengo yaro inogona kukanganisa zvinotengwa nevanhu.

Kutsigirwa kwesoftware uye vatyairi kunogona kukanganisa mashandiro anoita GPU uye kugara yakagadzikana.

Tichitarisa kumberi, makambani ese ari maviri acharamba achikanda miganhu yezvinogoneka.

Company Backgrounds

Kana tikatarisa AMD neNVIDIA, kuziva nhoroondo dzavo kunotibatsira kunzwisisa mabasa avo azvino. Tichaongorora budiriro yavo yakakosha, hutsva, uye mipiro kumusika. Izvi zvinosanganisira mitsara yavo yeGPU, iyo Radeon uye GeForce nhevedzano.

A. AMD

Advanced Micro Devices (AMD) yakatanga muna 1969 semiconductor mugadziri. Nekufamba kwenguva, yakaita zvakawanda zvakakosha, kunyanya muGPUs neRadeon yayo yakatevedzana. AMD's maGPU akura zvakanyanya, nekuda kwekuenderera mberi kwekuvandudza tekinoroji.

AMD's Radeon GPUs ndeyevatambi uye nyanzvi. Iwo akanakira kutamba, kugadzira zvemukati, uye kushanda munzvimbo dzedata. Ivo vanotarisa pakuita-simba-simba uye simba, kukwikwidza neNVIDIA's GeForce.

B. NVIDIA

NVIDIA Corporation yakatanga muna 1993 uye yakakurumidza kuve zita repamusoro muGPUs. Mutsetse wavo weGeForce wakachinja mutambo uye uchiri kutungamirira mukuita uye magirafu. NVIDIA zvakare inokanganisa nzvimbo dzedata uye yepamusoro komputa.

Kubudirira kweNVIDIA kunobva kune yavo CUDA software. Ndiyo kiyi yekufanana komputa uye inosimudzira GeForce GPUs. Izvi zvinoita kuti vakoshese mabasa anoda simba rakawanda rekombuta.

GPU Architecture uye Tekinoroji

Hondo pakati pe AMD neNVIDIA mumusika weGPU inokurudzirwa neadzo ekucheka-kumucheto zvivakwa. Isu tichatarisa AMD's RDNA uye RDNA 2 uye NVIDIA's Turing uye Ampere. Izvi zvicharatidza maitiro avo akasiyana uye hunyanzvi hwetekinoroji.

A. AMD's RDNA uye RDNA 2 Architectures

AMD's RDNA architecture yakatanga kuonekwa muRadeon RX 5000 series. Mutsivi wayo, RDNA 2, inopa simba iyo Radeon RX 6000 yakatevedzana. Aya mavakirwo anounza kuvandudzwa kukuru mukuita uye kugona.

RDNA 2 ine yakakwira transistor kuverenga uye iri nani yekugadzira maitiro. Yakagadzirwa neTSMC vachishandisa 7nm maitiro, ivo vanopa zvirinani zvemitambo realism uye kushandisa simba.

RDNA 2 inounzawo chaiyo-nguva ray tracing. Izvi zvinoita kuti maGPU e AMD ave akanaka kune vatambi nevagadziri. Kutarisisa kwekuita kwemitambo, nekuda kweakawanda transistors uye kugadzira kwakanaka, kunovandudza ruzivo rwemushandisi.

B. NVIDIA's Turing uye Ampere Architectures

NVIDIA's Turing architecture yakaunza chaiyo-nguva ray tracing uye AI-yakavakirwa kupa. Iyo nyowani ampere architecture, inowanikwa muGeForce RTX 30 akatevedzana, inoenda zvakatopfuura. Iyo inoshandisa yakakwira transistor kuverenga uye yepamusoro kugadzira maitiro neSamsung pane 8nm maitiro.

Iyo ampere architecture inopa zvirinani kuita pane watt uye yakawanda komputa simba. Inobatanidza advanced AI uye mamwe transistors. Izvi zvinoita kuti NVIDIA ive mukwikwidzi akasimba mumunda weGPU.

Kuenzanisa Kwekuita

Kutarisa AMD uye NVIDIA GPUs inoratidza masimba avo mumitambo uye mabasa ebasa. Kadhi rega rega rakanakira zvido zvakasiyana, zvichiita kuti sarudzo yakanaka yakakosha.

Kutamba Kwemitambo

Benchmark bvunzo dzinoratidza AMD uye NVIDIA GPUs vanoita zvakanaka mumitambo. Iyo Radeon RX 6800 XT kubva ku AMD uye iyo GeForce RTX 3080 kubva kuNVIDIA inomira pachena. Ivo vanopa nekukurumidza furemu mareti uye yakawanda yeVRAM, kiyi yemitambo yanhasi.

AMD inotarisa pakuwana kukosha kwakanyanya kwemari, kunyanya pa1440p. NVIDIA, zvisinei, inotungamira mu4K ine yavo DLSS tech.
