Tensor uye RT cores haitore nzvimbo yakawanda paNVIDIA Turing GPUs

Kunyangwe panguva yekuziviswa kweiyo yekutanga GeForce RTX 20 akateedzana makadhi evhidhiyo, vazhinji vaitenda kuti Turing GPUs inokwereta kwete zvachose zvidiki kuvapo kwemamwe mayuniti: RT cores uye tensor cores. Zvino, mumwe mushandisi weReddit akaongorora infrared mifananidzo yeTuring TU106 uye TU116 GPUs uye akagumisa kuti mayuniti matsva emakomputa haatore nzvimbo yakawanda sezvaifungwa pakutanga.

Kutanga, ngatirangarirei kuti Turing TU106 GPU ndiyo diki uye yakanyanya compact NVIDIA chip ine yakakosha RT cores yekuronda ray uye tensor cores yekumhanyisa mabasa ehungwaru hwekugadzira. Nekudaro, iyo Turing TU116 graphics processor, ine hukama nayo, inonyimwa aya akakosha mayuniti emakomputa uye ndosaka zvakasarudzwa kuaenzanisa.

NVIDIA Turing GPUs yakakamurwa kuita TPC mayuniti, ayo anosanganisira maviri ekutepfenyura akawanda (Streaming Multiprocessors), ayo anotosanganisira ese ekombuta cores. Uye sezvazvinozoitika, iyo Turing TU106 GPU ine chete 1,95 mmΒ² yakawanda TPC nzvimbo pane iyo Turing TU116, kana 22%. Yenzvimbo iyi, 1,25 mmΒ² ndeye tensor cores, uye chete 0,7 mmΒ² ndeye RT cores.

Zvinoitika kuti pasina iyo nyowani tensor uye RT cores, iyo mureza weTuring TU102 mifananidzo processor, iri pasi peGeForce RTX 2080 Ti, yaizogara kwete 754 mmΒ², asi 684 mmΒ² (36 TPC). Nekudaro, iyo Turing TU104, inova hwaro hweGeForce RTX 2080, inogona kutora 498 mmΒ² panzvimbo ye545 mmΒ² (24 TPC). Sezvauri kuona, kunyangwe pasina tensor uye RT cores, ekare Turing GPU angave akakura machipisi. Zvinonyanya kukosha Pascal GPUs.

Saka chii chikonzero chehukuru hwakakura kudaro? Kutanga, Turing GPUs dzave nehukuru hwecache saizi. Saizi yemashadhi yakawedzera zvakare, uye Turing machipisi ane akakura ekuraira seti uye akakura marejista. Zvese izvi zvakaita kuti zvikwanise kuwedzera zvakanyanya kwete chete nzvimbo, asiwo kuita kweTuring GPUs. Semuenzaniso, iyo yakafanana GeForce RTX 2060 yakavakirwa paTU106 inopa inenge yakaenzana nhanho yekuita seGeForce GTX 1080 yakavakirwa paGP104. Iyo yekupedzisira, nenzira, ine 25% yakakura nhamba yeCUDA cores, kunyangwe ichitora nzvimbo ye314 mm2 maringe ne410 mm2 yeTU106 nyowani.
