I mer \u00e4n ett \u00e5r, efter uppt\u00e4ckten av Spectre och Meltdown, har marknaden f\u00f6r processorer skakats av nya och nya s\u00e5rbarheter relaterade till spekulativa ber\u00e4kningar. De mest s\u00e5rbara \u00e4r inklusive<\/a><\/noindex> den senaste<\/a><\/noindex> ZombieLoad<\/a><\/noindex>, som drabbade Intel-chip. Sj\u00e4lvklart har AMD utnyttjat detta genom att betona s\u00e4kerheten hos sina CPU:er.<\/p>\n

\"AMD<\/p>\n

P\u00e5 sidan<\/noindex>, relaterat till Spectre-liknande s\u00e5rbarheter, meddelade f\u00f6retaget stolt: «Vi p\u00e5 AMD utvecklar v\u00e5ra produkter och tj\u00e4nster med s\u00e4kerhetskrav i \u00e5tanke. Baserat p\u00e5 genomf\u00f6rda interna analyser och diskussioner med s\u00e4kerhetsforskare, anser vi att v\u00e5ra produkter inte \u00e4r s\u00e5rbara f\u00f6r attacker Fallout, RIDL<\/a><\/noindex> eller ZombieLoad<\/a><\/noindex> p\u00e5 grund av att vi har h\u00e5rdvaru skyddskontroller i v\u00e5r arkitektur. Vi har inte kunnat \u00e5terskapa dessa s\u00e5rbarheter p\u00e5 AMD-produkter och har inga uppgifter om att n\u00e5gon annan har lyckats med detta». Det rapporteras att AMD:s processorer inte \u00e4r s\u00e5rbara f\u00f6r en annan attack MDS<\/a><\/noindex> — Store-to-Leak Forwarding<\/a><\/noindex>.<\/p>\n

Som ett resultat av uppt\u00e4ckten av fler och fler s\u00e5rbarheter och behovet av tillverkare att inf\u00f6ra l\u00e4mpliga patchar, kan AMD:s processorer visa sig vara mer presterande \u00e4n konkurrentl\u00f6sningar enligt en nyligen genomf\u00f6rd oberoende forskningen<\/a><\/noindex>, utf\u00f6rd av Phoronix, visar att till\u00e4mpningen av hela spektrumet av patchar f\u00f6r den identifierade upps\u00e4ttningen av processors\u00e5rbarheter relaterade till spekulativa ber\u00e4kningar resulterar i en genomsnittlig prestandaf\u00f6rlust p\u00e5 16 % f\u00f6r Intel-processorer (med Hyper-Threading avst\u00e4ngt \u2014 upp till 25 %). F\u00f6r AMD:s Zen+-processorer \u00e4r prestandaf\u00f6rlusten under samma f\u00f6rh\u00e5llanden endast 3 %.<\/p>\n

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

V\u00e4rre \u00e4r att: Apple och Google r\u00e5der<\/a><\/noindex> anv\u00e4ndare av Intel m\u00e5ste helt st\u00e4nga av Hyper-Threading, vilket kan s\u00e4nka prestandan med upp till 40-50 % (beroende p\u00e5 uppgiften). Sj\u00e4lva Intel rekommenderar att man inte g\u00f6r detta<\/a><\/noindex> i de flesta fall, men problemet kan vara s\u00e4rskilt kritiskt f\u00f6r arbetsstationer, servrar och andra omr\u00e5den som \u00e4r k\u00e4nsliga f\u00f6r prestanda och s\u00e4kerhet. I fallet med AMD-chip kr\u00e4vs det inte att st\u00e4nga av en liknande teknik, Simultaneous Multi-Threading. Dessutom kan den str\u00f6m av nyheter om s\u00e5rbarheter, inklusive uppgifter om f\u00f6rs\u00f6k fr\u00e5n Intel att d\u00f6lja information<\/a><\/noindex> fr\u00e5n allm\u00e4nheten, inte undg\u00e5 att p\u00e5verka image hos det senare.<\/p>\n

Dessa nyheter kommer vid en s\u00e4rskilt d\u00e5lig tid f\u00f6r Intel: AMD \u00e4r p\u00e5 v\u00e4g att sl\u00e4ppa en serie moderna 7-nanometer CPU:er med Zen 2-arkitektur f\u00f6r b\u00e5de station\u00e4ra och servrar. Under tiden anv\u00e4nder Intel fortfarande en mycket gammal (i termer av processteknikens utveckling) 14-nanometerteknik och kan inte fortfarande starta massproduktion av 10-nanometerchip. Allt detta gynnar AMD, som med st\u00f6rsta sannolikhet kommer att forts\u00e4tta \u00f6ka sin marknadsandel.<\/p>\n
