Le nakong ea phatlalatso ea likarete tsa video tsa pele tsa GeForce RTX 20, ba bangata ba ne ba lumela hore li-GPU tsa Turing ha li na molato ho hang ka lebaka la boteng ba li-unit tse ling: RT cores le tensor cores. Joale, mosebelisi a le mong oa Reddit o hlahlobile litšoantšo tsa infrared tsa Turing TU106 le TU116 GPUs mme a etsa qeto ea hore likarolo tse ncha tsa komporo ha li nke sebaka se ngata joalo ka ha ho ne ho nahanoa qalong.
Taba ea pele, a re hopoleng hore Turing TU106 GPU ke chip ea NVIDIA e nyane ka ho fetisisa ebile e kopane ka ho fetesisa e nang le li-cores tse khethehileng tsa RT bakeng sa ray tracing le tensor cores bakeng sa ho potlakisa mesebetsi ea bohlale ba maiketsetso. Ka lehlakoreng le leng, processor ea litšoantšo ea Turing TU116, e amanang le eona, e amohuoa likarolo tsena tse khethehileng tsa komporo ke ka lebaka leo ho ileng ha etsoa qeto ea ho li bapisa.
Li-GPU tsa NVIDIA Turing li arotsoe ka lihlopha tsa TPC, tse kenyelletsang li-multiprocessors tse phallelang (Streaming Multiprocessors), tse seng li kenyelletsa li-cores tsohle tsa k'homphieutha. 'Me ha e le hantle, Turing TU106 GPU e na le sebaka sa TPC sa 1,95 mm² ho feta Turing TU116, kapa 22%. Sebakeng sena, 1,25 mm² ke ea li-tensor cores, 'me ke 0,7 mm² feela ke ea RT cores.
Ho ile ha fumaneha hore ntle le li-cores tse ncha tsa tensor le RT, processor ea litšoantšo tsa Turing TU102, e ka tlase ho GeForce RTX 2080 Ti, e ne e ke ke ea nka 754 mm², empa 684 mm² (36 TPC). Ka lehlakoreng le leng, Turing TU104, e leng motheo oa GeForce RTX 2080, e ka nka 498 mm² sebakeng sa 545 mm² (24 TPC). Joalokaha u bona, le ntle le li-cores tsa tensor le RT, li-GPU tsa khale tsa Turing e ka ba lichifi tse kholo haholo. Haholo-holo Pascal GPUs.
Joale lebaka la boholo bo bokaalo ke lefe? Ha e qala, li-GPU tsa Turing li bile le boholo bo boholo ba cache. Boholo ba li-shaders le bona bo ekelitsoe, 'me li-chips tsa Turing li na le li-sete tse kholo tsa litaelo le lirekoto tse kholoanyane. Sena sohle se entse hore ho khonehe ho eketsa haholo eseng feela sebaka, empa le ts'ebetso ea Turing GPUs. Ka mohlala, GeForce RTX 2060 e tšoanang e thehiloeng ho TU106 e fana ka hoo e batlang e le boemo bo lekanang le ba GeForce GTX 1080 e thehiloeng ho GP104. Ea morao-rao, ka tsela, e na le palo e kholo ea 25% ea li-cores tsa CUDA, leha e nka sebaka sa 314 mm2 khahlano le 410 mm2 bakeng sa TU106 e ncha.
