Ukwethulwa kwe-AMD ku-CES 2020 bekuqukethe imininingwane ethokozisayo ngemikhiqizo emisha yenkampani kanye nabalingani bayo abaseduze kakhulu kunokukhishwa kwabezindaba okushicilelwe ngemuva komcimbi. Abamele inkampani bakhulume ngomphumela we-synergistic otholakala ngokusebenzisa ihluzo ze-AMD kanye neprosesa emaphakathi ohlelweni olulodwa. Ubuchwepheshe be-SmartShift bungathuthukisa ukusebenza kufika ku-12% ngokulawula ngamandla amafrikhwensi e-CPU ne-GPU ukuze kusatshalaliswe ngokufanele kakhulu umthwalo wekhompuyutha.
Umqondo wokuthuthukisa ukusetshenziswa kwezinsiza zehadiwe usunesikhathi eside uhlupha abathuthukisi bezingxenye zeselula. I-NVIDIA, ngokwesibonelo, ngaphakathi kohlaka lobuchwepheshe ikuvumela ukuthi ushintshe "ophapheme" usuke ezithombeni ezingacacile uye kuzithombe ezihlanganisiwe ukuze uthuthukise ukusetshenziswa kwamandla, kuye ngohlobo lomthwalo wekhompyutha. I-AMD iqhubekele phambili: njengengxenye yobuchwepheshe be-SmartShift owethulwe e-CES 2020, ihlongoza ukushintsha ngokuguquguqukayo amaza ephrosesa emaphakathi kanye nephrosesa yehluzo ecwebileyo ukuze kuqinisekiswe ibhalansi efanele yokusebenza kanye nokusetshenziswa kwamandla.
I-laptop yokuqala ezosekela i-SmartShift kuzoba i-Dell G5 SE, ezohlanganisa iphrosesa yochungechunge lwe-hybrid engu-7nm Ryzen 4000 kanye nemifanekiso ehlukene ye-Radeon RX 5600M, okungesinye sezimo eziyinhloko zobuchwepheshe be-SmartShift. I-laptop izongena emakethe ngekota yesibili iqala ku-$799.
Emidlalweni, ukusetshenziswa kobuchwepheshe be-SmartShift kuzokhuphula ukusebenza kuze kufike ku-10%; ezinhlelweni ezifana ne-Cinebench R20, ukunyuka kungafinyelela ku-12%. Ubuchwepheshe buzosetshenziswa kumasistimu weselula nawedeskithophu. Into esemqoka ukuthi iphrosesa emaphakathi ye-AMD kuzo iseduze nekhadi levidiyo elihlukile elisuselwa kuphrosesa yehluzo ye-Radeon. Phakathi kwezinye izinto, kumasistimu eselula iSmartShift izokwandisa impilo yebhethri ngaphandle kokushajwa kabusha.
I-chip encane ye-7nm processors U-Renoir wahlala e-monolithic
Ku-CES 2020, isikhulu esiphezulu se-AMD uLisa Su isampula ye-7nm Renoir hybrid processor. Ngokusho kwedatha yokuqala, ikristalu ye-monolithic inendawo engekho ngaphezu kwe-150 mm2, futhi leli lungiselelo liyihlukanisa nozakwabo bekhompiyutha kanye neseva. Ngendlela, ama-processor we-Renoir nawo awanikezi ukwesekwa kwe-PCI Express 4.0, akhawule ku-PCI Express 3.0. I-subsystem ye-Radeon graphics (ngaphandle kokucacisa isizukulwane) ekucushweni okuphezulu inikeza amayunithi okubulala ayisishiyagalombili, futhi inqolobane yezinga lesithathu ilinganiselwe kuma-megabytes angu-8. Kuyacaca ukuthi kungani i-AMD kufanele "isindise i-silicon." Kodwa-ke, lokhu akuzange kuthinte amakhompiyutha ekhompiyutha - angaba yisishiyagalombili kuwo ku-compact chip enjalo.
U-Lisa Su wachaza ukuthi ngenxa yokwanda okuphindwe kabili kokusebenza kahle kwamandla ka-Renoir processors uma kuqhathaniswa nabanduleli be-12-nm, umuntu kufanele abonge kakhulu ubuchwepheshe be-7-nm - yilesi sici esanquma ukuphakama okunjalo ngama-70%, futhi kuphela ama-30% ahlobene nezakhiwo kanye nezakhiwo. izinguquko zesakhiwo. Amakhompyutha aphathekayo okuqala asekelwe ku-Renoir azovela kwikota yamanje; ekupheleni kwalo nyaka, amamodeli aphathwayo angaphezu kwekhulu asekelwe kulawa maphrosesa azokhululwa.
Njengoba uLisa Su engeze, i-AMD ihlose ukuthuthukisa futhi ikhulule imikhiqizo engaphezu kwamashumi amabili ye-7nm kulo nyaka kanye nonyaka odlule. Lokhu kufaka phakathi imikhiqizo yesizukulwane sesibili ye-7nm, kodwa abameleli be-AMD bachazele umhleli we-AnandTech u-Ian Cutress ukuthi ama-Renoir APUs ambulwe kuleli sonto akhiqizwa kusetshenziswa ubuchwepheshe obufanayo besizukulwane sokuqala se-7nm njengoMatisse noma iRoma. Imikhiqizo ye-AMD esebenzisa lokho okubizwa nge-EUV lithography izoqala ukukhiqizwa yi-TSMC ngokuhamba kwesikhathi - ngokusho kwedatha engekho emthethweni, eduze nekota yesithathu yalo nyaka.
