Pl\u0103cile grafice NVIDIA nu au oferit din ultimele ani gameriilor obi\u0219nui\u021bi ocazia de a face overclocking.

\u00cen recenzia ini\u021bial\u0103 a Radeon RX 5700 \u0219i Radeon RX 5700 XT, am observat deja c\u0103 pe ambele pl\u0103ci, procesoarele grafice func\u021bioneaz\u0103 cu o tensiune de alimentare excesiv\u0103. Se pare c\u0103 AMD a hot\u0103r\u00e2t din nou s\u0103 overclockeze cipurile cu orice pre\u021b \u00eenainte de lansarea \u00een v\u00e2nzare \u0219i s-a asigurat cu o tensiune ridicat\u0103 datorit\u0103 inevitablei variabilit\u0103\u021bi \u00een calitatea siliciului. Iar \u00een vremurile Radeon RX 480, compania promitea s\u0103 elimine tensiunea excesiv\u0103 pentru a nu \u00eenc\u0103lzi aerul degeaba. Chiar avem slide-uri din 2016 cu aceste declara\u021bii.<\/p>\n

Din fericire, ceea ce inginerii AMD nu au realizat, cump\u0103r\u0103torul unei pl\u0103ci video poate s\u0103 fac\u0103 singur. \u00cen primele \u00eencerc\u0103ri de undervolting pentru Radeon RX 5700 \u0219i Radeon RX 5700 XT, am \u00eencercat s\u0103 nu pierdem niciun FPS \u00een jocuri \u0219i am ob\u021binut deja o reducere semnificativ\u0103 a consumului de energie. \u00cens\u0103, zgomotul sistemului de r\u0103cire de referin\u021b\u0103 ne determin\u0103 s\u0103 ac\u021bion\u0103m mai activ. Pentru a g\u0103si echilibrul optim \u00eentre performan\u021b\u0103 \u0219i putere, readuc\u00e2nd Navi \u00een pozi\u021bia optim\u0103 a curbei de eficien\u021b\u0103 energetic\u0103, trebuie s\u0103 reducem, \u00eempreun\u0103 cu tensiunea de alimentare, frecven\u021bele de v\u00e2rf ale GPU-ului. La Radeon RX 5700 XT, am redus frecven\u021ba maxim\u0103 a nucleului de la 2010 la 1860, iar tensiunea de alimentare - de la 1,193 la 0,991 V. Desigur, anumite pierderi de performan\u021b\u0103 \u00een acest caz sunt inevitabile, dar nu sunt at\u00e2t de mari pe c\u00e2t s-ar putea presupune \u00een func\u021bie de frecven\u021bele maxime, - aici vom avea timp s\u0103 ne convingem.<\/p>\n

Parametrii standard ai versiunii inferioare Radeon RX 5700 sunt deja aproape de zona confortabil\u0103 a cipului Navi, dar optimizarea ulterioar\u0103 este \u00een continuare posibil\u0103. Pentru a reduce tensiunea de alimentare a GPU-ului de la 0,979 la 0,839 V, este suficient s\u0103 ne oprim la o frecven\u021b\u0103 de v\u00e2rf de 1700 MHz \u00een loc de 1750.<\/p>\n\n\n\n

Judec\u00e2nd dup\u0103 m\u0103sur\u0103torile preliminare din Crysis 3 \u0219i parametrii de lucru \u00een jocurile moderne, tabelele software PowerPlay \u0219i-au f\u0103cut treaba. Cu o frecven\u021b\u0103 medie a GPU-ului de 1864 MHz, pe care Radeon RX 5700 XT o men\u021bine \u00een 12 jocuri de testare, seniorul Navi a s\u0103rit la 2100 MHz, iar valoarea frecven\u021bei instantanee atinge 2141 MHz. Delta frecven\u021belor variaz\u0103 \u00eentre 153 \u0219i 305 MHz, \u00een func\u021bie de aplica\u021bia specific\u0103 \u0219i reprezint\u0103 o expresie relativ\u0103 de 8\u201317%.<\/p>\n

Dar, a\u0219a cum era de a\u0219teptat, toat\u0103 eficien\u021ba energetic\u0103 a lui Navi s-a evaporat complet la acest overclocking. Chip-ul func\u021bioneaz\u0103 practic continuu sub o tensiune destul de \u00eengrijor\u0103toare de 1,245 V (aceast\u0103 tensiune era necesar\u0103 acum \u0219apte ani pentru overclocking-ul procesorilor grafic Tahiti, construite pe o norm\u0103 de 28 nm), iar puterea consumat\u0103 \u00een Crysis 3 a atins 325 \u00een loc de 222 W \u00een modul standard. Nu degeaba am pornit turbina de referin\u021b\u0103 la tura\u021bii maxime: temperatura GPU-ului la senzorul de margine a sc\u0103zut chiar de la 80 la 77 \u00b0C, iar chip-urile GDDR6 - de la 82 la 78 \u00b0C. Dar, indicatorul de temperatur\u0103 critic\u0103 (Junction Temperature) a crescut totu\u0219i de la 92 la 101 \u00b0C - e foarte aproape de 110 \u00b0C, dup\u0103 care \u00eencepe throttlingul automat.<\/p>\n

Zgomotul sistemului de r\u0103cire care func\u021bioneaz\u0103 la o vitez\u0103 de aproximativ 4500 rotiri pe minut, de\u0219i \u00eenc\u00e2nt\u0103 urechile adev\u0103ratului overclock-er, este complet inacceptabil pentru utilizare constant\u0103. Placa Radeon RX 5700 XT, overclockat\u0103 la limita sa, are nevoie evident de un cooler mai puternic \u2014 ideal ceva de tip triple-slot cu mai multe ventilatoare, sau chiar mai bine, un sistem de r\u0103cire cu ap\u0103. Din fericire, blocurile de ap\u0103 pentru pl\u0103cile de referin\u021b\u0103 au \u00eenceput deja s\u0103 apar\u0103 la v\u00e2nzare.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n

Modelul de baz\u0103 Radeon RX 5700 s-a overclockat \u0219i mai bine datorit\u0103 tabelelor software PowerPlay, \u0219i \u00een ansamblu, pare mai viabil. \u00cen loc de frecven\u021ba medie stabil\u0103 de 1683 MHz \u00een jocurile de testare, am ob\u021binut 2053 MHz, iar diferen\u021ba dintre frecven\u021bele de overclockare \u0219i cele de baz\u0103 variaz\u0103 \u00eentre 325 \u0219i 353 MHz (19\u201321%). RX 5700 overclockat func\u021bioneaz\u0103 la o frecven\u021b\u0103 superioar\u0103 nivelului standard XT, dar tensiunea de alimentare este practic aceea\u0219i \u2014 1,093 V. Cre\u0219terea puterii de la 187 la 250 W \u2014 aceasta nu este, desigur, o veste prea \u00eembucur\u0103toare, dar dac\u0103 compar\u0103m ambele pl\u0103ci video \u00een overclockare, modelul superior c\u00e2\u0219tig\u0103 doar 72 MHz \u00een medie \u00een frecven\u021bele de joc, consum\u00e2nd cu 75 W mai mult.

Observ\u0103m c\u0103 \u0219i la pl\u0103cile video NVIDIA, overclockingul se blocheaz\u0103 pu\u021bin peste 2 GHz, cu o tensiune de alimentare comparabil\u0103 cu cea a Radeon RX 5700, de\u0219i cipurile Turing nu dispun de o fotolitografie la fel de fin\u0103 ca Navi de 7 nanometri. Cu toate acestea, cre\u0219terea densit\u0103\u021bii tranzistorilor, asigurat\u0103 de noul proces tehnologic TSMC, nu \u00eenseamn\u0103 \u00eentotdeauna c\u0103 tensiunea de alimentare (mai ales dincolo de condi\u021biile tipice de func\u021bionare) trebuie s\u0103 fie mai mic\u0103.<\/p>\n

R\u0103cirea avansat\u0103 la maximul turbinelor nu este la fel de esen\u021bial\u0103 pentru overclocking-ul Radeon RX 5700 ca \u00een cazul modelului XT, fiind necesar\u0103 doar ca o m\u0103sur\u0103 de precau\u021bie pentru a evita throttling-ul. \u00cen testul Crysis 3, temperatura maxim\u0103 a GPU-ului, m\u0103surat\u0103 de senzorul de margine, a sc\u0103zut de la 81 la 66 \u00b0C, temperatura de jonc\u021biune a r\u0103mas \u00eentre 79 \u0219i 80, iar cipurile GDDR6 nu s-au \u00eencins peste 72 \u00b0C.

To assess gaming performance, we limited tests to a resolution of 1440p: in this mode, the Radeon RX 5700 and RX 5700 XT do not reach the limits of CPU performance, and at 4K with maximum graphics quality settings, graphics cards of this level sometimes provide such a low frame rate that it is impossible to compare the results with the necessary accuracy. As you may have guessed from the hints scattered throughout the theoretical part of the review, overclocking the Navi chips did not yield the kind of results one might expect when looking at raw clock speeds.<\/p>\n

Radeon RX 5700 XT, \u00een ciuda cre\u0219terii medii a frecven\u021bei GPU de 13% (\u0219i a puterii cu 106 W), a ob\u021binut doar 5% FPS-uri suplimentare. \u0218i, dac\u0103 analiz\u0103m parametrii \u00een jocuri individuale, \u00een medie doar 44% din performan\u021ba teoretic\u0103 oferit\u0103 de overclocking s-a reflectat \u00een rezultatele testelor.

Principala cauz\u0103 care poate explica rezultatele dezam\u0103gitoare este deficitul de l\u0103\u021bime de band\u0103 a memoriei RAM (MBW), deoarece modelul inferior are o performan\u021b\u0103 care coreleaz\u0103 mai str\u00e2ns cu frecven\u021bele de lucru.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

Radeon RX 5700 a atins \u00een overclocking o cre\u0219tere de 13% a framerate-ului cu o cre\u0219tere medie a frecven\u021belor de 21% - astfel, 63% din puterea de calcul suplimentar\u0103 a ajuns la benchmarck-uri. Este de remarcat c\u0103 memoria RAM Micron de pe placa RX 5700 s-a overclockat mai bine dec\u00e2t cipurile Samsung de la Radeon RX 5700 XT (14,8 fa\u021b\u0103 de 14,4 Gbps), dar scalarea slab\u0103 a FPS-ului \u00een overclocking-ul modelului de top Navi este pu\u021bin probabil s\u0103 poat\u0103 fi atribuit\u0103 diferen\u021bei de 3% \u00een MBW.

Totu\u0219i, nu ar trebui s\u0103 ne ia \u00een der\u00e2dere Radeon RX 5700 XT \u0219i dezvoltatorii AMD pentru c\u0103 acestui GPU \u00eei lipse\u0219te DSP. Dac\u0103 compar\u0103m datele acceleratoarelor NVIDIA din familia GeForce RTX 20, putem observa c\u0103, pe m\u0103sur\u0103 ce GPU devine mai mare, mai multe gigaflopuri se risipesc. Viteza limitat\u0103 a memoriei RAM ar putea juca un rol semnificativ \u00een acest sens, deoarece toate modelele bazate pe TU106 \u0219i TU104, cu excep\u021bia GeForce RTX 2060, au aceea\u0219i configura\u021bie RAM, iar cea mai mare salt \u00een raportul dintre performan\u021ba teoretic\u0103 \u0219i rezultatele \u00een jocuri are loc \u00eentre RTX 2060 \u0219i RTX 2060 SUPER: modelul de baz\u0103 are un bus de memorie de 192 de bi\u021bi, iar SUPER - de 256 de bi\u021bi. Nu este de mirare c\u0103 NVIDIA a \u00eenceput s\u0103 foloseasc\u0103 chip-uri GDDR6 cu l\u0103\u021bimi de band\u0103 de 16 Gb\/s pe pl\u0103cile GeForce RTX 2080 SUPER.<\/p>\n

Radeon RX 5700 XT a scos la iveal\u0103 o problem\u0103 cu care s-au confruntat ambii produc\u0103tori de procesoare grafice, deoarece niciun chip NVIDIA nu poate fi overclockat at\u00e2t de mult f\u0103r\u0103 modific\u0103ri hardware (cu excep\u021bia pl\u0103cilor 'elit', pentru care exist\u0103 firmware \u0219i software oferite doar la cerere special\u0103). Cu toate acestea, vina pentru lacrimile overclock-erilor se afl\u0103, cel mai probabil, \u0219i la echipa software a Radeon Technologies Group. Problemele cu ritmul constant de redare a cadrelor pe Navi exist\u0103 chiar \u0219i la frecven\u021bele de baz\u0103. \u00cen plus, RDNA este o arhitectur\u0103 grafic\u0103 complet nou\u0103, iar perfec\u021bionarea driverului \u00eenainte de lansarea seriei 5000 de la AMD, ca de obicei la aceast\u0103 companie, nu a fost finalizat\u0103.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
