Isikhathi esingaphezu konyaka ngemva kokutholwa kwe-Specter ne-Meltdown, imakethe yokucubungula ibilokhu imatasatasa ngokutholwa kobungozi obuningi obuhlobene nekhompuyutha eqagelayo. Okungenwa kakhulu kuzo , kuvele ukuthi ama-Intel chips. Vele, i-AMD ayizange yehluleke ukusebenzisa leli thuba ngokugxila ekuvikelekeni kwama-CPU ayo.
In , ezinikele ebuthakathakeni obufana ne-Specter, inkampani ngokuziqhenya yathi: βKwa-AMD, siklama imikhiqizo yethu namasevisi sicabangela ukuphepha. Ngokusekelwe ekuhlaziyweni kwethu kwangaphakathi nezingxoxo nabacwaningi bezokuphepha, sikholelwa ukuthi imikhiqizo yethu ayinakho ukuhlaselwa. noma ngenxa yokuba khona kokuhlolwa kokuphepha kwehadiwe ekwakhiweni kwethu. Asikwazanga ukuphindaphinda lobu buthakathaka emikhiqizweni ye-AMD futhi asinabo ubufakazi bokuthi kukhona omunye umuntu okwazile ukufeza lokhu.β Ama-CPU e-AMD Kubikwa ukuthi Akanangozi Kokunye Ukuhlasela - .
Njengomphumela wokutholakala kobungozi obuningi obusha kanye nesidingo sokuthi abakhiqizi bafake ama-patches afanelekile kubo, amaphrosesa e-AMD angase akhiqize kakhudlwana kunezixazululo zezimbangi, ngokusho kombiko ozimele wakamuva. , olwenziwa iwebhusayithi ye-Phoronix, ukusebenzisa uhla olugcwele lokulungiswa kwesethi ekhonjiwe yobungozi beprosesa obuhlobene nekhompyutha eqagelayo kuholela ekwehleni kokusebenza kwe-Intel CPU ngesilinganiso esingu-16% (nge-Hyper-Threading ikhutshaziwe - ngo-25%). Endabeni yamaphrosesa e-AMD Zen+, ukusebenza ngaphansi kwezimo ezifanayo kwehla ngo-3% kuphela.
Okubi kakhulu: I-Apple ne-Google Abasebenzisi be-Intel kufanele bakhubaze i-Hyper-Threading ngokuphelele, okungase ngezinye izikhathi kunciphise ukusebenza kuze kufike ku-40-50% (kuya ngomsebenzi). I-Intel ngokwayo ezimweni eziningi, kodwa inkinga ingaba bucayi ikakhulukazi ezindaweni zokusebenza, amaseva nezinye izindawo zokusebenza nezokuphepha ezibucayi. Endabeni yama-chips e-AMD, ukukhubaza ubuchwepheshe obufanayo be-Multi-Threading obufanayo akudingekile. Ngaphezu kwalokho, inqwaba yezindaba mayelana nokuba sengozini, okuhlanganisa ulwazi mayelana emphakathini awukwazi kodwa ukuthonya isithombe sakamuva.
Lezi zindaba zifika ngesikhathi esibi kakhulu ku-Intel: I-AMD isizokhulula umndeni wama-CPU athuthukisiwe angu-7nm anezakhiwo ze-Zen 2 zedeskithophu kanye nomsebenzi weseva. Ngaleso sikhathi, i-Intel isasebenzisa indala kakhulu (kusukela lapho kubhekwa khona ukuthuthukiswa kwenqubo yezobuchwepheshe) ubuchwepheshe be-14-nm futhi ayikwazi ukwethula ukuphrinta okukhulu kwama-chips angu-10-nm. Konke lokhu kudlala ezandleni ze-AMD, okungenzeka ukuthi izoqhubeka nokwandisa isabelo sayo semakethe ngenxa yalokho.
