Osmijádro Intel Core i9-9900KS s all-core turbem 5,0 GHz bude mít TDP zvednuté na 127 W

Včera jsme tu měli zprávu o Core i9-10900X, tedy desetijádrovém modelu procesorů Cascade Lake-X pro platformu X299 (socket LGA 2066). Současně zdá se utekl ještě jeden procesor Intelu – tentokrát mainstreamové osmijádro Intel Core i9-9900KS, které bude speciální tím, že bude poskytovat Turbo Boost 5,0 GHz při všech jádrech aktivních (zatímco i9-9900K jen na dvou). Od tohoto speciálního procesoru Intel sice už prozradil hlavní parametry, ale neřekl tehdy, jaké bude mít TDP. To ovšem teď prosáklo.

Core i9-9900KS se teď poprvé objevilo v seznamu podporovaných CPU u základních desek, a to po poslední aktualizaci BIOSu konkrétně u Asusu. Podle seznamu Core i9-9900KS přinese zvýšení TDP. Intel u šestijádrových i osmijádrových Coffee Lake ponechal původně TDP na stejných 95 W, které předtím měly stanovené čtyřjádra (Skylake, Kaby Lake). Core i9-9900KS ho ovšem zvýší na 127 W (nejde o překlep, seznam skutečně uvádí toto číslo a ne 125 nebo 130 W, které byste čekali).

Toto je poprvé za velmi dlouhou dobu, co mainstreamové CPU (do socketu LGA 115x) má vyšší TDP než 95 W, od roku 2011 za celou dobu od Sandy Bridge přes Haswell a deriváty Skylake bylo 95 W vždy strop. Důvod je ovšem asi nabíledni. Core i9-9900KS má základní frekvenci 4,0 GHz, zatímco Core i9-9900K jen 3,6 GHz. Zvýšení tohoto taktu o víc jak 10 % patrně nebylo dosažitelné jen vybíráním nejkvalitnějšího křemíku běžícího na nižších napětích a muselo být zvýšené TDP. Jeho posazení o nějakou třetinu výš také znamená, že tento procesor bude mít větší minimální požadavky na výkon chlazení a kapacitu napájecí kaskády na desce.

Platí nicméně pořád to, že v zátěži při aktivním turbo boostu bude CPU mít spotřebu vyšší než 127 W. TDP je totiž Intelem definováno právě pro základní takty, při turbo boostu má čip takříkajíc „volné ruce“, respektive se řídí jiným limitem příkonu, který se označuje PL2. Jak vysoká bude spotřeba Core i9-9900KS při onomu turbu 5,0 GHz, zatím nevíme, ale měla by logicky být vyšší než na Core i9-9900K, které má se všemi jádry aktivními povoleno maximálně 4,7 GHz. Spotřeba se ovšem asi bude lišit také podle charakteru aplikace. Software používající 256bitové instrukce AVX a AVX5 bude dosahovat vyšších spotřeb, enormně zatěžující programy jako Prime95 nebo jiný stress test pak ještě vyšší. S vyšší spotřebou ale asi zájemci už počítali a hráčům „trhat žíly“ nebude.

Intel už sdělil, že Core i9-9900KS začne prodávat příští měsíc, tedy v říjnu. Co se však zatím nikde neobjevilo, je informace o ceně. Intel pravděpodobně nechá Core i9-9900K na současné úrovni (488 dolarů/14 tisíc Kč), takže Core i9-9900KS by mělo stát víc. Ale o kolik víc, to těžko říct.
