Odpovede na tuto otazku su vo vacsine pripadov rovnake.
Preto som ich tu zosumarizoval.
Aky je vlastne rozdiel medzi jednojadrovym a dvojjadrovym procesorom ?
Ako uz nazov napoveda, rozdiel je v pocte jadier.Dvojjadrovy procesor (DC) ich ma dve, stvorjadrovy (quad core - QC) ich ma styri atD.
Vo vseobecnosti su to tzv. multi core procesory.Procesory s vacsim poctom jadier.Jednojadrovy (SC) ma iba jedno jadro.
Multi core procesory mozu vykonavat naraz viacej threadov ako single core procesory.Preto dosahuju aj vyssi vykon.Pri multithreadingu (vykonavanie viacerych aplikacii naraz) sa na single core procesory vykonavaju tieto zaradom.Pri multi core procesory sa tieto aplikacie mozu vykonavat naraz.Kazda na jednom jadre.
Ake dual core procesory existuju/ budu vydane ?

Okrem tychto dual core procesorov, existuju od AMD/Intel aj ine DC procesory - specialne pre servery.Tieto a ine menej rozsirene dual core procesory od IBM, Via atD som vynechal.

Aj tu existuju este ine quad core procesory (hlavne pre servery), ktore vsak vynecham.
Pri com maju multi core procesory vyhodu ?
Hlavna vyhoda multi core procesorov je v multitaskingu.Procesor je schopny rychlejsie spracovavat naraz viacej aplikacii ako single core.V buducnosti bude existovat cim Dalej tym viac aplikacii (ako WinRAR od verzie 3.6, DivX od verzie 6.0), ktore budu schopne vytazit obidve (u DC) jadra (Multithreading).Preto su multi core procesory v podobnych aplikaciach vykonnejsie ako rovnako taktovane single core procesory.
QC procesory sa zatial vyuzivane hlavne v serveroch a menej v desktopoch.
Na THG existuje moznost priamo si porovnat vykon SC a DC procesora vo zvolenej aplikacii
Starsie hry nepodporuju DC, pri takych hrach je lepsie mat vysoko nataktovany SC procesor.
Kdo chce vsak hrat nove a buduce hry, tomu odporucam multi core procesory.Vacsina novych hier uz podporuje DC.
Takisto aj ovladace grafickych kariet su optimalizovane pre DC.
Ovladace nVidia ForceWare od verzie 8x.xx a ATi Catalysty od verzie 5.12.Ziskany vykon sa pohybuje okolo ~ 7% (podla hry).
Mam DC procesor, musim znovu nainstalovat Windows ?
Vo vseobecnosti to nie je nutne, ale odporuca sa, pretoze sa musi nainstalovat novy ovladac CPU (ACPI multicore ovladac).
V niektorych pripadoch sa tento ovladac aktualizoval aj bez novej instalacie Win.Moze to vsak sposobit nestabilitu systemu.
Spolocne s instalaciou Windowsu sa odporuca aj Bios-update.
Dalej je nutne si uvedomit, ze Windows XP Home Edition podporuje len 2 jadra.Pre viac jadrove procesory alebo aj Pentium EE s Hyper-Threadingom (4 virtualne jadra) je nutne mat Windows XP Profesional Edition.
Po uspesnej instalacii, by sa mali v Taskmanageri zobrazit 2 priebehy zatazenia CPU :
Pokial sa prechadza z DC procesora na iny DC model je nova instalacia Windowsu nutna.
Musim nainstalovat este nejake PATCHe, aby moj DC procesor pracoval spravne ?
Okrem ACPI multi core ovladaca je potrebne este nainstalovat Dalsie PATCHe, aby sa cely vykon DC procesora prejavil.
Na systemy s Windows XP a SP2 je odporucane nainstalovat DC Hotfix (KB896256) od Microsoftu.Tento PATCH sa musi po instalacii este pomocou zapisu do registra zapnut.Vykonat sa to da manualne:
Alebo pomocou pribaleneho suboru - dc-pat_akt.zip na zapnutie a dc-pat_deakt.zip na vypnutie v pripade problemov s danym PATCHom.1. Kliknite na tlacidlo start, kliknite na prikaz Spustit, zadajte prikaz "regedit" (bez ") a potom kliknite na tlacidlo OK.
2. Kliknite pravym tlacidlom mysi na polozku "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager" ukazte na polozku Novy a potom kliknite na prikaz Kluc.
3. Ako nazov noveho kluca zadajte retazec "Throttle" (bez ").
4. Kliknite pravym tlacidlom mysi na polozku Throttle, ukazte na polozku Novy a potom kliknite na polozku Hodnota DWORD.
5. Ako nazov hodnoty zadajte retazec "PerfEnablePackageIdle" (bez ").
6. Kliknite pravym tlacidlom mysi na polozku PerfEnablePackageIdle a potom kliknite na prikaz Upravit.
7. Do pola udaj hodnoty zadajte hodnotu 1. Uistite sa, ze v dialógovom okne uprava hodnoty DWORD je vybrana moznost sestnastkova a potom kliknite na tlacidlo OK.
Poznamka: Ak chete zakazat spravanie novej politiky stavu vykonu, zadajte do pola udajov hodnoty hodnotu 0.
8. Zatvorte Editor databazy Registry.
Pokial chcete u DC procesorov od AMD vyuzivat funkciu Cool'n'Quiet je nutne stiahnut tento ovladac - Download
Okrem toho existuje pre DC procesory od AMD tzv.Dual-Core Optimizer, ktory moze v urcitych hrach zvysit vykon - Download
(AMD Athlon™ 64 X2 Dual Core Processor Utilities & Updates)
Mozem konkretnej aplikacii prikazat aby bezala len na jednom jadre ?
ano, tato moznost existuje.
Programy beziace v pozadi (ako firewall, antivirus) mozu bezat na inom jadre ako primarne aplikacie.
Toto nastavenia sa da vykonat v Taskmanageri.
Na to sa musi kliknut konkretna aplikacia pravou mysou a udat jej prislusnost k jadru.Problem je ,ze sa toto priradenie po novom starte systemu strati.
Preto existuju aplikacie, ktore dovoluju dlhdobo priradit aplikaciu k jadru. (napr. Task Assignment Manager - Download)
