Nel database del test di prestazioni SiSoftware \u00e8 stata trovata una registrazione riguardante il test di un server o di una workstation costruita con due misteriosi processori Intel a sei core. Questi processori sono interessanti principalmente per il fatto che hanno una quantit\u00e0 di cache di secondo livello piuttosto insolita \u2014 1,25 MB per ogni core.<\/p>\n

\"La<\/p>\n

Questo \u00e8 cinque volte di pi\u00f9 rispetto ai 256 KB di cache L2 dei processori desktop Coffee Lake Refresh, e due volte e mezzo in pi\u00f9 rispetto ai pi\u00f9 recenti chip Ice Lake-U, che hanno 512 KB per core. Inoltre, \u00e8 il 25% in pi\u00f9 rispetto agli attuali processori HEDT Core-X o ai server Xeon Scalable, che hanno 1 MB di cache di secondo livello per core.<\/p>\n

\"La<\/p>\n

Pertanto, si deduce naturalmente che questo processore utilizza una delle nuove architetture Intel. Potrebbero essere gli Ice Lake a 10 nm o i Tiger Lake, oppure i Rocket Lake a 14 nm. Di queste ultime due architetture al momento si sa poco, ma una delle recenti fughe di notizie<\/a><\/noindex> su Tiger Lake indicava proprio che possedeva 1,25 MB di cache di secondo livello per core.<\/p>\n

Allo stesso tempo, un'altra fuga di notizie<\/a><\/noindex> ha indicato che nella famiglia Tiger Lake saranno presentati solo processori mobili con un massimo di quattro core. D'altra parte, i chip Rocket Lake offriranno fino a otto core. Inoltre, i chip a sei core testati in SiSoftware hanno meno cache di terzo livello rispetto al precedentemente \"trapelato\" Tiger Lake.<\/p>\n

<\/center><\/p>\n

E qui si pu\u00f2 gi\u00e0 ipotizzare che una minore quantit\u00e0 di cache L3 possa essere il risultato di una disposizione dei transistor meno densa, ovvero di un processo tecnologico pi\u00f9 \"grande\". Non si pu\u00f2 escludere che qui stiamo assistendo a un trasferimento dell'architettura da un processo a 10 nm pi\u00f9 \"sottile\" al buon vecchio 14 nm. Recentemente proprio riportato<\/a><\/noindex>, Rocket Lake utilizzer\u00e0 una nuova architettura, ma su un vecchio processo tecnologico.<\/p>\n

\"La<\/p>\n

C'\u00e8 anche un'altra possibilit\u00e0: tutto quanto descritto nei due paragrafi precedenti non si verificher\u00e0, e ci troveremo davanti a un sistema su due processori server Ice Lake-SP da 10 nm. Potrebbero benissimo avere gli stessi core degli Ice Lake-U mobili, ma ogni core potrebbe avere pi\u00f9 cache di secondo livello. Per Intel, una pratica simile non \u00e8 nuova.<\/p>\n

In generale, \u00e8 difficile trarre conclusioni specifiche basate su questo risultato. Ci sono molte possibilit\u00e0, come vedete, e poche prove. L'unica cosa di cui si pu\u00f2 essere certi \u2014 \u00e8 che questi processori a sei core non derivano da Skylake.<\/p>\n
