Očekuješ jako puno toga :D
A ovo nije flejmanje!?

Zanimljivo kako na svome siteu Nvidia spominje samo taj assisted computing, od performansi ni traga :)

Samo komentiram tvoje pretpostavke i očekivanja koja temeljiš na rekla-kazala.
Izvalio si da je ATI samo za jeftino igranje i tu sam te ispravio.

Ta mu je bila dobra.
Izgleda da če ipak 470 konkurirat 5870 a 480 dvoglavoj.

Pa vec dugo nvidia pokusava se prosiriti na vise grana ne samo da ih se iskljucivo gleda kao neka gaming oprema (iskljucujuci one bolestine tipa tesla itd), iako je ovo burek na njihovoj stranici di govore o 512 Cuda cores a zna se da nema jos takve kartice :D (samo sa 448), steta sto nitko od developera nece ulagati niti vrijeme niti lovu za razvijanje engina koji bi koristio tu arhitekturu u potpunosti mislim da bi evidentna bila razlika, prebrzo izlaze nove generacije kartica nije kao u slucaju konzola da se nis nemjenja po 5-6 godina, iako bi moglo u buducnosti izaci nesto korisno od toga posto vec 2-3 generacije nvidia konstantno pumpa tu Cudu...
A ako je itko i gledao koji interview sa Carmackom koji kaze da njihov novi engine (rage) ce podrzavati Cuda-a arhitekturu ujedno i Cell i Intel Larrabee, tako da bi se ako bude uspjesan engine kao dosadasnji moglo ocekivati da se vise developera okrene tome, bar kako ja to vidim...

A o neiskoristenome potencijalu necu niti pricati, samo za primjer bi naveo PlayStation 3 koji se sastoji od cella u kombinaciji sa gpu-om od 7800GTX te 256 radne memorije i kada pogledam kako neke igre izgledaju (iako je u engine ulozeno oko 3-4godine i dosta para) a radi se o zastarjelom hardveru mogu si mislit sto bi se moglo sa trenutacnim hardverom napravit....

Pa da ali to je ujedno i greska Ati-a, sam da napravis anketu Cuda ili Ati Stream mislim da bi ih velika vecina odgovorila Cuda jer su negdje nesto culi o tome :)
Slicna je stvar sa plazmama i lcd-ima, kada uce seljo u pevec i ide nadobudno kupiti telku, on je negdje davno cuo nesto od lcd-u i uzet ce prije nego plazmu iako je po kvaliteti redosljed obrnut :) marketing samo marketing...

Na ovo je mislio valjda:

Also, we received news about targeted prices for the parts, and they look quite competitive against six-month old ATI 5800 Series: according to the benchmarks leaked some time ago, GeForce GTX 470 will beat out HD 5850 and in some cases, even HD 5870 - for the price of HD 5850 - we were told that the ballpark figure is $299-349, while GTX 480 will run between $449-499.

http://www.brightsideofnews.com/news...s-confirm.aspx
...However, it was only last night when we were finally confirmed the reason for renaming the parts from GeForce GTX 370 and GTX 380 into GTX 470 and GTX 480 series. When nVidia introduced their GF100 chip, the company claimed the part comes with 512 cores, 64 Texture units and 384-bit memory controller. However, due to problematic yields for 40nm process for both AMD and nVidia, the number of 512-core parts is quite limited. In fact, it is limited to the point where only Tesla C2070 [coming in 3Q 2010] and top-end Quadro board, the "FX 5900" should feature 512 cores [Tesla is announced, Quadro is not]. If our multiple sources are to believe, GeForce GTX 480 is set to debut with 480 shader cores, a number that will certainly curb a lot of enthusiasm for the part...
Znaci punokrvni Gt300 chipovi ce se skupljat za Tesla kartice a srot u proizvodnji ce ici u Fermi gtx480 i gtx 470 buahahaha

Bacite oko na dvoznamenkaste brojke u gornjem ljevom kutu, da nije broj funkcionalnih chipova?:D

Ajde bar nije sve tako crno - preporucena cijena nece bit tako parena kao sto se pretpostavljalo - mozda padnu cijene

Report: Nvidia GTX 480, 470 Availability Delayed

Citiraj:
It's no secret that making Fermi has been a harder-than-expected task for Nvidia, but the company will officially unveil its finalized product in the GeForce GTX 480 at the end of next week on March 26.

While you can expect to see an announcement at an event at PAX East coupled with plenty of benchmarks, a story posted on Shane Baxtor's site says that retail availability will come after the announcement date.

According to Baxtor, the original retail date was supposed to be March 29 but now that's been moved to April 6.

We reached out to Nvidia for clarification, but we were told to stay tuned to the company's stage show from 6 p.m. to 7 p.m. next Friday. At any rate, hopefully those boxes for Inno3D GeForce GTX 480 were filled with product and ready to greet gamers as soon as possible.
Nvidia GeForce GTX 480 Die Shots Appear Online

Citiraj:
Nvidia may still be hanging on tightly to its GeForce GTX 470 and GTX 480 GPUs, it seems that some overseas have managed to get their hands on some Fermi silicon.
Earlier this month, German publication Heise (translated) featured two photographs of a GeForce GTX 480 that clearly showed an A2 stepping stamp. The publication measured the package to be 42mm × 42mm.

More recently Expreview captured images found on Chinese forum NGA showing more detailed die shots of GeForce GTX 480 silicon with A3 stepping. The die measured 23mm x 23mm, or 529 square millimeters.

Nvidia Shows GeForce GTX 480 ''Hair'' Rendering

Citiraj:
Nvidia shows off how Fermi will make flowing hair look in fancy tech demo.


When new GPUs are in development, it's not uncommon for there to be a myriad of tech demos that show all the new realism features afforded by the new technology.
One such steady improvement seen by increasingly powerful graphics hardware is more realistic hair. No longer is hair just a few triangles stuck together, giving 3D characters a look that can only be achieved in real life with an entire can of hairspray.
Netbooknews captured this Nvidia tech demo at GDC, which shows off Fermi's fancy hair rendering prowess.

Web source reveals supposed TDP, SP count and pricing for the upcoming Nvidia "Fermi" graphics cards.

Website VR-Zone claims to have received what are supposedly the final specifications for the upcoming Nvidia GeForce GTX 480 and GTX 470 GPUs.

The site lists the following information:
GeForce GTX 480 : 512 SP, 384-bit, 295W TDP, US$499
GeForce GTX 470 : 448 SP, 320-bit, 225W TDP, US$349
Internal benchmarks reveal that GeForce GTX 470 is some 5-10% faster than Radeon HD 5850 and similiar [sic] for GeForce GTX 480 over the Radeon HD 5870.

Also found onVR-Zone's forums is a picture from Turkish website DonanimHaber of what is purported to be the first Nvidia-made picture of the GeForce GTX 480 card:

Exactly a week ahead of releasing its GeForce GTX 400 series accelerators, NVIDIAhttp://images.intellitxt.com/ast/adT...lass_10x10.gif held meetings with the press discussing the company's newest technologies, including GeForce GTX 400 series. Some lesser known details about the GeForce GTX 480 and GeForce GTX 470 surfaced, among more known and established ones. To begin with, the GeForce GTX 480 is confirmed to have a CUDA core (shader core) count of 480. The GF100 core operates at 700 MHz, its shader domain at 1401 MHz, and the memory operates at 924 MHz (actual, 1848 MHz DDR, 3700 MHz effective). With a GDDR5 memory bus width of 384-bit, the effective memory bandwidth would be 173.4 GB/s.

The GeForce GTX 470, on the other hand, has 448 CUDA cores, clock speeds of 607 MHz core, 1215 MHz shader domain, and 837 MHz memory (actual, 1674 MHz DDR, 3348 MHz effective). With a GDDR5 memory bus width of 320-bit, the effective memory bandwidth would be 130.7 GB/s. While the GTX 480 has a board power of 295W, the GTX 470 has a board power of 225W. Another piece of information the source reveals is that internal testing by NVIDIA showed that the performance level to expect from the GeForce GTX 470 should be 5-10% higher than that of the ATI Radeonhttp://images.intellitxt.com/ast/adT...lass_10x10.gif HD 5850. The GeForce GTX 480 should be expected to be just that much faster than the ATI Radeon HD 5870. It is also expected that the target price of the GeForce GTX 480 should be typically US $499, while the GTX 470 should go typically for US $349. Detailed reviews of the two should be up by this time, next week.

Interestingly, the TDP of GeForce GTX 480 is almost similar to Radeon HD 5970 which is a dual GPU card. Interestingly, our sources revealed that there are indeed plans for dual Fermi cards and the TDP of the card is probably gonna be mind blowing.

As we inch closer to Nvidia's official launch of Fermi next week, it's only natural that we start seeing more details leak out from OEM product partners.
We know that most of you are clamoring for more scrumptious box shots, but as a bonus today we've also come across on Chinese site Expreview (translated) some full-frontal pictures of XFX's GeForce GTX 480 and GTX 470 cards.

Nvidia initial batch of GeForce GTX 400 series to have fewer cores than expected
 
Malo glasina:)

Citiraj:
Nvidia's initial batch of GeForce GTX 480/470-based graphics cards will have fewer cores than the originally expected 512 due to low 40nm yield at Taiwan Semiconductor Manufacturing Company (TSMC), according to sources from graphics card makers.

Since TSMC's 40nm yield currently is still lower than 50%, Nvidia will block some of the graphics cores with problems on the card. As a result, the GeForce GTX 480 will only have 480 cores and GTX 470 only 448, the sources noted.

The sources pointed out that Nvidia will start selling its GeForce GTX 400 series on March 26, but volume shipments will not start until April 6. The sources also noted that GeForce GTX 480 will be priced at US$499 and GeForce GTX 470 at US$349.

Nvidia has declined to comment on unannounced products.

Asus and MSI to Support GeForce GTX 480 Voltage Tweaks
 
Citiraj:
Yeah, yeah, it's another one of these Nvidia GeForce GTX 480 and GTX 470 box shot stories. Unfortunately, we're not allowed to show you much else until the curtain officially lifts this Friday evening, so all we have to stare at are pretty boxes that the new video cards will be coming in.

Asus fans will be pleased to know that their favorite Taiwanese computer maker will be offering both the GeForce GTX 480 and GTX 470; and if the box art is of any indication, Asus' product will pack a special (supported?) feature that will allow the user to tweak the voltage to "shift into overdrive" to make things "50% faster."

zkljaja 25.03.2010. 09:41
I onako se po glasinama prica o blizu 300w, nema te sta bit strah za napajanje, vec dali ce to el. mreza izdrzat :D

Leadtek-ica mi daleko najljepse izgleda, pitanje je dali ce i efikasnost hladnjaka biti na razini...
