A trecut deja mai bine de un an de la descoperirea Spectre \u0219i Meltdown, iar pia\u021ba procesoarelor este zguduit\u0103 de descoperirea unor noi vulnerabilit\u0103\u021bi legate de calculul speculativ. Cele mai afectate au fost inclusiv<\/a><\/noindex> \u00faltima<\/a><\/noindex> ZombieLoad<\/a><\/noindex>, cipurile Intel. Desigur, AMD nu a ezitat s\u0103 profite de pe urma acestui lucru, pun\u00e2nd accent pe securitatea procesoarelor sale.<\/p>\n

\"AMD,<\/p>\n

Pe ap\u0103rea un mesaj c\u0103 laserul nu este disponibil pentru moment \u0219i un indiciu: \u00een birou s-au fumat siguran\u021bele, trebuie s\u0103 suni compania de administrare \u0219i s\u0103 ceri alimentarea.<\/noindex>, dedicat\u0103 vulnerabilit\u0103\u021bilor de tip Spectre, compania a anun\u021bat cu m\u00e2ndrie: «La AMD, dezvolt\u0103m produsele \u0219i serviciile noastre av\u00e2nd \u00een vedere cerin\u021bele de securitate. Pe baza analizei interne efectuate \u0219i a discu\u021biilor cu cercet\u0103torii \u00een domeniul securit\u0103\u021bii, consider\u0103m c\u0103 produsele noastre nu sunt expuse atacurilor Fallout, RIDL<\/a><\/noindex> sau ZombieLoad<\/a><\/noindex> datorit\u0103 existen\u021bei verific\u0103rilor hardware de protec\u021bie \u00een arhitectura noastr\u0103. Nu am reu\u0219it s\u0103 reproducem aceste vulnerabilit\u0103\u021bi pe produsele AMD \u0219i nu avem informa\u021bii c\u0103 altcineva ar fi reu\u0219it s\u0103 fac\u0103 acest lucru». Se raporteaz\u0103 c\u0103 CPU-urile AMD sunt rezistente \u0219i la o alt\u0103 atac MDS<\/a><\/noindex> \u2014 Store-to-Leak Forwarding<\/a><\/noindex>.<\/p>\n

\u00cen urma descoperirii unor noi vulnerabilit\u0103\u021bi \u0219i a necesit\u0103\u021bii produc\u0103torilor de a implementa patch-uri corespunz\u0103toare, procesoarele AMD ar putea fi mai performante dec\u00e2t solu\u021biile competitorilor, conform unei recente analize independente cercet\u0103rii<\/a><\/noindex>, realizat de site-ul Phoronix, utilizarea \u00eentregului spectru de corec\u021bii pentru complexul de vulnerabilit\u0103\u021bi ale procesorului legate de calculul speculativ duce la o sc\u0103dere a performan\u021bei CPU-urilor Intel \u00een medie cu 16 % (c\u00e2nd Hyper-Threading este dezactivat — p\u00e2n\u0103 la 25 %). \u00cen cazul procesorilor AMD Zen+, performan\u021ba \u00een acelea\u0219i condi\u021bii scade doar cu 3 %.<\/p>\n

<\/center>
\n\"AMD,<\/p>\n

Mai r\u0103u, Apple \u0219i Google recomand\u0103<\/a><\/noindex> utilizatorii Intel trebuie s\u0103 dezactiveze complet Hyper-Threading, ceea ce poate reduce performan\u021ba cu p\u00e2n\u0103 la 40–50 % (\u00een func\u021bie de sarcin\u0103). \u00cen sine, Intel recomand\u0103 s\u0103 nu se fac\u0103 acest lucru<\/a><\/noindex> \u00een majoritatea cazurilor, dar problema ar putea fi deosebit de critic\u0103 pentru sta\u021bii de lucru, servere \u0219i alte domenii sensibile la performan\u021b\u0103 \u0219i securitate. \u00cen cazul cipurilor AMD, dezactivarea unei tehnologii similare, Simultaneous Multi-Threading, nu este necesar\u0103. \u00cen plus, fluxul de \u0219tiri despre vulnerabilit\u0103\u021bi, inclusiv informa\u021bii despre \u00eencerc\u0103rile Intel de a ascunde informa\u021biile<\/a><\/noindex> de la public, nu poate s\u0103 nu influen\u021beze imaginea companiei.<\/p>\n

Aceste \u0219tiri vin \u00eentr-un moment deosebit de defavorabil pentru Intel: AMD se preg\u0103te\u0219te s\u0103 lanseze o familie de procesoare moderne de 7 nanometri cu arhitectura Zen 2 pentru sarcini de birou \u0219i servere. \u00centre timp, Intel \u00eenc\u0103 folose\u0219te o tehnologie de 14 nm, foarte veche (din perspectiva dezvolt\u0103rii procesului tehnologic) \u0219i nu reu\u0219e\u0219te s\u0103 ini\u021bieze produc\u021bia de mas\u0103 a cipurilor de 10 nm. Toate acestea favorizeaz\u0103 AMD, care cu siguran\u021b\u0103 va continua s\u0103-\u0219i creasc\u0103 cota de pia\u021b\u0103.<\/p>\n
