Intel Core i7 (Nehalem) - recenzie, informácie...

[faugusztin]

Vyzera ze sa zachovava, pokym ho nevypnes. Mne teraz CPU-Z zobrazuje na mojej doske nasobic x21, co je pre i5 750 mozne iba s turbom ak dobre viem. Takze aktualne mam maximalny takt 160x21=3360MHz s i5 750.

tak ako to je s tym pretaktovanim a turbom? aj ked pretaktujem cpu tak turbo sa zachova alebo nie?

zachová, avšak je zcela logické, že výsledný OC bude nižší (jelikož turbo navyšuje citelně násobič, od určitého kroku by toto navýšenbí způsobilo pád systému...4ili s turbem bych taktoval (biosově) tak do 3.5 GHz

[miso2911]

preto sa pytam ci sa oplati kupovat nejake 1600Mhz ramky alebo ci stacia 1333Mhz

Je libo Gulftown a jeho OC možnosti s LN2?

Core i5 750 vs. Core i7 860 vs. Core2Quad Q6600 vs. Core i7 920 vs. Phenom II X4 965 - porovnanie na rovnakých frekvenciách

For the most part comparing the Core 2 Quad Q6600 and the Core i5 750 is like comparing chalk and cheese, the Lynnfield architecture is just so much more refined when compared to Kentsfield. Clocking both processors at 3.60GHz showed huge performance gains in favor of the Core i5 750 when testing with software such as WinRAR, Excel and Photoshop. Furthermore, when it came time for gaming performance, the Core i5 750 was just as impressive, leaving the Q6600 well behind.

That said, there would be no mad rush for Core 2 Quad Q6600 owners to upgrade to the Core i5 750, as they still have a very capable processor, particularly if they are overclocking it to 3.0GHz or beyond. However, for those building a new system, it is safe to say that you can forget that the LGA775 platform and all its processors even exist.

Perhaps a more important comparison is between the Core i5 750 and the Phenom II X4 processors. Again when clocked at either 2.80GHz or 3.60GHz the Core i5 750 smashed the Phenom II X4 965. While the Phenom II X4 965 was able to dispatch of the Q6600, the new Core i5 750 proved to be far too much. Regardless of whether you plan to overclock a Phenom II X4 processor or not, it has little chance against the Core i5 750 on a clock for clock basis.

The most surprising match up was between the Core i5 750 and Core i7 860, which I mentioned was our original intention for this article. When clocked at the same frequency there is little difference between these two processors, and when pushing them as high as 3.60GHz there really is no difference. Of course the only difference between the two is the Hyper-Threading support of the Core i7 860, which really failed to help it in the majority of our tests.

The Core i7 920 was slightly faster than the Core i7 860 and Core i5 750 processors when comparing clock for clock performance, and honestly if I really wanted Hyper-Threading support this is the path I would choose to get it. The Core i7 920 consistently delivered the best performance, even in our gaming tests.

bohužel, znovu neznalost redaktorů...nezvýšili uncore Phenomů II...dá se říci, že cca PHenom II s krokem 400 MHz uncore nahoru se rovná výkonu stejně jako +100 MHz na CPU.

[Shatterhand]

Ale no tak Priznaj, ze clock-for-clock je jednoducho i5 a i7 lepsi

[flanker]

to ano ,ale když už taktovali, měly využít potenciálu PII a ne pouze "klasický" OC. Pokud by byl zájem, můžu zkusit porovnání třeba 4000 MHz+default uncore vs 3800MHZ+2800MHz uncore

Gulftown a WR 3D06

zaujimave. ale core i7 neni 32nm procesor alebo uz vyrabaju aj taky ?

[miso2911]

niak si zaspal dobu... ano Gulftown bude vyrabany v roku 2010 32nm procesom

[adun]

core i5 i3
kedy budu tieto procesory resp. ich mobilne upravy v notebookoch vie niekto ?

[faugusztin]

Clarksfield (i7, quad core) uz su - 720QM, 820QM a 920XM.

Na zvysok (Arrandale) si musis pockat :

tak to bude masaker, i7 v laptope
