[Anandtech] Nehalem EP Opens "Grand Canyon" Gap over AMD

We were quite amazed, even slightly suspicious, when HP and Fujitsu-Siemens Published their SAP numbers. These numbers showed that the newest Xeon X5570 (Nehalem EP) series offer an enormous performance boost over the Xeon X5470 (Harpertown). After all, an almost 100% improvement at a slightly lower speed (2.93 GHz vs 3.3 GHz) is nothing short of amazing. Turns out that the real clockspeed is 3.2 GHz (2.93 GHz + 266 MHz turbo) but that does not alter the fact that these are truly incredible performance numbers.

Difficult times ahead for AMD
Even if AMD is able to speed up beyond 3 GHz, chances are slim that AMD will be able to compete with the new Nehalem Xeons. Add Turbo mode, hyperthreading, a lower latency memory controller and a better integer core together and you get a performance gap the size of the "Grand Canyon".

So does AMD have any chance at all beyond a new architecture in 2011? Is it over and out for AMD in 2009 and 2010? Adding 2 cores at the end of 2009 is a good step in the right direction. But even if AMD executes flawlessly the 32 nm Xeon Westmere will only give a window of a few months to the AMD hexacore "Istanbul". Istanbul should appear at the end of 2009, the Westmere Xeon is scheduled for very early 2010.

Westmere has few performance optimizations, it seems to be a pretty straight forward shrink. Slightly higher clockspeeds, about 20% lower power consumption, and yet another addition to the ridiculously long list of SSE-instructions in the form of seven new instructions (six instructions are for crypto/AES acceleration). Westmere is only an evolutionary step forward, but the "Grand Canyon" gap that Nehalem EP has made is probably large enough.

*Ne donosi puno poboljshanja, chak i sa 2gb nema toliko znacajne razlike-

From a gaming perspective, though, even at the ultra intensive 2560 x 1600 resolution the extra memory does very little for extra performance and while your games might load ever so slightly faster, for people on a tight or strict budget the increase doesn't warrant the extra cost that is carried with moving to a 6GB kit.

Depending on who you are will decide on how much memory you get. If you have the money or just want the best you're going to end up with 6GB. If you multi-task a lot and use your computer for work that runs memory intensive programs, then you will no doubt end up with 6GB or even 12GB.

If you're on a budget or would rather spend the money you save by buying a 3GB kit over a 6GB one in order to upgrade your graphics card, you will end up with 3GB of memory and still be extremely happy.

Don't let someone tell you that buying 6GB is a must; if you're not the kind of user that is going to use it, the money could be better spent in other areas where a bigger impact will be made on performance.

Intel Core i7 CPU Cooler Roundup

hladjenje Core i7 josh uvijek otezhano, na 3.5Ghz najbolji kuleri ga jedva spushtaju ispod 70C pod opterecenjem...Trebace radikalna promjena u dizajnu, ili nam se mozda blizhi prelazak na vodeno hladjenje, koje se dosta usavrshilo proteklih godina, kao uobichajen vid hladjenja...

As for the coolers themselves, the Noctua NH-U12P CPU Cooler is the winner in our testing. Either in its original single fan configuration or in its new SE1366 dual fan configuration it led the pack and did it quietly. With a little Googling the NH-U12P SE1366 can be found for as little as $63 +shipping. The original NH-U12P can be found for $50+shipping, but you would have to buy or wait for the LGA1366 mount to be sent to you. If you’re upgrading your current rig then I would suggest buying the original and waiting for the bracket, but if you’re building the whole new system then get the SE1366 version.

Legit Bottom Line: The Intel Core i7 CPUs can get very toasty so the need of a quality cooler is a must. The Noctua NH-U12P is just that and will continue to be our King of Cooling.

Evo... Niko nije otvorio TOPIC pa odlucih da ga napravim.
Intel Core i7 je najnoviji tip procesora, ima 4 jezgra i HYPER THREADING tako da ga kompjuter vidi u Task i Device Manageru kao osmojezgarni.
Novi procesor ne moze da se ugradjuje u postojece ploce, za njega ide novi SOCKET LGA 1366
Zasad, jedini chipset koji podrzava ovaj procesor je Intelov X58, koji konacno objedinjuje nVidia SLI i Ati Crossfire.
Takodje, nov chipset&procesor podrzavaju Triple-channel memoriju. Svi koji prate kompjutere znaju sta je dual chanel. Triple radi na isti nacin, samo sto koristi 3 memorijska kontrolera i tako TEORIJSKI mnozi memorijski BANDWITH sa 3
Da se vratimo na procesor. Navodno podrzava iskljucivo DDR3 memoriju, ali cu morati detaljnije da provjerim da bih bio 100% siguran.
Procesor se radi u 45 nm i zasad imamo samo 5 modela iz 2 prodice... "obicne" i "extreme edition" - Extreme edition su procesori sa otkljucanim mnoziocem, namjenjeni overkloku.
Svi procesori rade na Base Clocku od 133Mhz, na dosta visocijim mnoziocima u odnosu na Core 2 Duo i Core 2 Quad.
Iz "obicne" serije imamo:
__________________________
Core i7 920 koji radi na 2.66GHz |133MHz X 20
Core i7 940 koji radi na 2.93GHz |133MHz X 22
Core i7 950 koji radi na 3.06GHz |133MHz X 23
__________________________
Extreme edition modeli su:
__________________________
Core i7 965 Extreme Edition 3.20GHz | 133MHz X 24
Core i7 975 Extreme Edition 3.33GHz | 133MHz X 25

Da nebi bilo zabune, drugi broj je mnozilac. Koliko sam cuo, procesor se dosta dobro overklokuje.
Ukoliko vam se ne ulazu neke velike pare, najbolje je kupiri Core i7 920 i overklokovati ga na nekih 3Ghz.
Da ironija bude veca, svi procesori imaju istu CACHE memoriju. Ona iznosi 256 KB L2/po jezgru i 8 MB shared L3.
TDP svih gore navedenih i7 procesora na fabrickim clockovima iznosi 130W

[Stivi]

i treba dodati da podrzavaju Triple-Channel Memory

i da je pozeljno (nisam siguran jeli obavezno) da budu tri slota popunjena memorijom - DDR III

naravno da su najbolja kombinacija Triple Channel Kitovi

[cvxcomputers]

Bravo... Znam da sam zaboravio nesto sad cu dodati

Ajde da podpomognemo temu....zadnji proc je 975 a ne 965 extreme... 950 i 975 su sa novim stepinzima DO i trebalo bi da se bolje klokuju...
i7 rade iskljucivo sa ddr3 memorijom i to ne bilo kojom, nego memorijom deklarisanom za to ( u prevodu memorija koja ima xmp profil odnosno deklarisana na rad do 1.65v ) memorijski kontroler je integrisan u proc pa zbog toga memorija na vishem taktu od 1.65v moze da sprzi procesor ( pod uslovom da se isti ne overklokuje odnosno napon vezan za mem kontroler u proc. se ne podigne na vishu vrednost ( do 1.4v je zdravo preko toga proc moze da oboli-degradira )...mnozioci se povecavaju za jedan kada se aktivira turbo opcija u biosu....extreme varijante imaju otkljucan mnozilac...BCLK takozvani interni klok 133 default se dize u zavisnosti od ploce do cak 232 (ovo pod jako dobrim hladjenjem-LN2)naravno sve sa max mnoziocima ......huh...... pisacu jos kada bude vremena a i izbacim mozda koju slicicu i screen sa rezultatima testova sintetickih...

hahahahah najjace da cemo 3 strane topika na kojem ima sve zhivo za nehalem arhitekturu da kopiramo...
ti nisi koristio search, core i7 je pomenut mnogo puta na ovom topiku, i eto ti ga u 5 prvih rezultata pretrage kad ukucas Core i7....

inace topik se redovno osvjezhava, bio je na 10to mjesto na prvoj strani...
