De\u0219i aceste CPU sunt \u00een multe privin\u021be asem\u0103n\u0103toare cu predecesorii lor din familia Coffee Lake, compania Intel le clasific\u0103 \u00een a noua genera\u021bie Core \u0219i le numeroteaz\u0103 cu indec\u0219i care \u00eencep cu cifra 9. \u0218i dac\u0103 \u00een cazul Core i7 \u0219i Core i9 aceast\u0103 clasificare poate fi \u00eentr-o oarecare m\u0103sur\u0103 justificat\u0103, av\u00e2nd \u00een vedere c\u0103 au ob\u021binut pentru prima dat\u0103 opt nuclee de calcul, noile procesoare din seriile Core i5 \u0219i Core i3 au primit o cre\u0219tere a numerelor de model \u00een mare parte doar pentru a \u021bine companie. Practic, ele ofer\u0103 doar frecven\u021be de ceas mai mari.<\/p>\n<p>Totu\u0219i, nu se poate vorbi despre \u00eembun\u0103t\u0103\u021biri la nivel de microarhitectur\u0103. \u0218i, sincer, acest lucru nu mai mir\u0103 pe nimeni. Conceptul de dezvoltare practicat de Intel presupune c\u0103 schimb\u0103rile profunde \u00een procesoare sunt legate de \u00eembun\u0103t\u0103\u021birea tehnologiilor de produc\u021bie. Prin urmare, \u00eent\u00e2rzierile cu implementarea procesului de tehnologie de 10 nm duc la faptul c\u0103 ne confrunt\u0103m din nou cu microarhitectura Skylake, care a fost lansat\u0103 \u00een 2015. Cu toate acestea, ceea ce este cu adev\u0103rat surprinz\u0103tor este c\u0103 Intel nu pare interesat\u0103 s\u0103 schimbe nici m\u0103car specifica\u021biile care nu necesit\u0103 transform\u0103ri semnificative. De exemplu, \u00een mod oficial, Coffee Lake Refresh continu\u0103 s\u0103 fie orientat c\u0103tre memoriile DDR4-2666 cu dou\u0103 canale, \u00een timp ce compania AMD adaug\u0103 constant suport pentru moduri mai rapide, ajung\u00e2nd \u00een ultimele versiuni de Raven Ridge mobile de p\u00e2n\u0103 la DDR4-3200. Singurul lucru pe care Intel l-a f\u0103cut \u00een r\u0103spuns a fost s\u0103 creasc\u0103 la 128 GB capacitatea de memorie suportat\u0103 \u00een sistemele bazate pe Coffee Lake Refresh.<\/p>\n<p>Cu toate acestea, \u00een ciuda lipsei schimb\u0103rilor \u00een microarhitectur\u0103, Intel reu\u0219e\u0219te \u00een continuare s\u0103 lanseze modele destul de interesante prin metode extensibile \u2013 cresc\u00e2nd num\u0103rul de nuclee de calcul \u0219i frecven\u021bele de ceas. Prima val\u0103 de anun\u021buri Coffee Lake Refresh, care a avut loc \u00een octombrie anul trecut, a adus trei procesoare de v\u00e2rf pentru overclocking, care au cucerit noi limite de performan\u021b\u0103: Core i9-9900K \u0219i Core i7-9700K cu opt nuclee, precum \u0219i Core i5-9600K cu \u0219ase nuclee. Cu a doua val\u0103, cea de Cr\u0103ciun, lista celor mai noi procesoare s-a completat cu \u00eenc\u0103 \u0219ase modele CPU mai accesibile.
