Nove ATI grafičke - vijesti i glasine

[drago7]

Sa jedne strane se govori i u samim specifikacijama DX10 se navodi da njegova neovisnost o snazi cpu-a, dok sa druge strane stižu vijesti o DX10.1 i posebnim optimizacijama za višejezgrene cpue, tako da se u samoj biti nezna što je istina a što dezinformacija,ili možda još koji marketinški trik.
Čini se da nas vuku za noseve, htjeli bi da se prodaje više jezgri, pošto nemogu više dizat megaherce i gigaherce. Volio bih kad bi bar 10% novijih igara znalo korristit bar dvije jezgre, ali je takvu igru dosta teško napravit, pa umjesto onih 10% imamo 0.0001%. Neznam u kojem ce to pravcu sve ic, ali prve naznake vidjet cemo za 3-4mjeseca u igri CRYSIS

Mislim da je realno za ocekivat da se pojavi neki programcic koji bi omogucivao da 2 jezgre rade kao jedna, jer sumljam da ce i ovak traljavo programirane igre bit znatno vise razvijane da bi iskoristile max od visejezgrenih proceva. Ionako tu glavnu rijec vodi GPU, jedna postena jezgra ostaje bez daha tek kod SLI kombinacija a sad se jos i ono govance za fiziku pokusava progurat tak da ne vidim smisla. Koliko god povecas snagu stroja toliko se vise moze sfusat na razvoju igre:/ Ovo s iganjem i hardwareom postaje suludo....

vrlo dobro receno : DualWiel

ako se ja dobro sjecam AMD radi na razvoju optimizacije suprotne od hyperthreadinga tj. ne dljenjenje jedne fizicke jzgre na dve ili vise nego obratno, dve fizicke petvarat u jednu logicku.
sto ce naravn o bit prva liga za sav softvafre koji nezna iskorisitit dve jezgre pa ce se emulacijom natjerat da ih iskoristi :-))

ATi has attempted to create good working versions of the R600 a number of times but, for various reasons, has needed to re-spin the GPU. The company is now up to spin A13.

With A11, as we understand it, the issue was very, very simple. Someone forgot to connect the pins that let the GPU communicate with the outside world.

We don't know the state of play with the A13 spin but do understand that ATi has got A12 running at a speed of 1GHz. ATi has looked at water-cooling and traditional air cooling. But, the speed of the processor and its resultant heat output have meant that ATi also had to consider more complex hi-tech solutions.

So, the company turned to NanoFoil cooling technology. This, as best we can understand, works by having ultra-thin nanolayers of aluminium and nickel that can be kicked into life by heat, electricity or mechanical or optical stimulation, causing a reaction that gives off heat in a controlled fashion.

Speaking at yesterday's AMD Financial Analysts Day, Executive Vice President of Visual and Media Businesses, Dave Orton, appeared to throw down the performance gauntlet in favor of AMD's upcoming R600 GPU. Having had over a month to study NVIDIA's G80, Orton did not seem the least bit intimidated. In a slide entitled "R600: Why we lead in graphics", Orton promised that even if the name of the company had changed, that the commitment to GPU performance leadership had not. He promised a "take no prisoners" approach to performance leadership for AMD's new GPU.

More interestingly, in his verbal remarks Orton reported (at roughly the 1:22:30 mark of the webcast) that one of R600's key advantages would be "new levels of memory bandwidth to the graphics subsystem, and bandwidth is critical to graphics performance." As all graphics geeks know, AMD pioneered the move to GDDR4 memory with the Radeon X1950 XTX, which gave them a temporary advantage in bandwidth. However, in the period since NVIDIA has released the 384-bit GeForce 8800 GTX, whose memory bandwidth crushes the X1950 XTX by 86.4GB/s to 64.0GB/s. It is impossible that AMD could regain a significant enough advantage in bandwidth to be cited by Orton as a major competitive advantage without following NVIDIA north of the 256-bit bus that has been a mainstay of the ATI/AMD high-end products since 2002's Radeon 9700 Pro.

R600 will therefore feature a 512-bit external memory bus, likely using 1.2GHz GDDR4 for ~153GB/sec from memory pool to chip, to back up the smack AMD's Executive Vice President laid down.

In other tidbits, Orton also vowed to be first to the 65nm technology process, but did not disclose which product he had in mind for the honor, nor even product type, GPU or chipset. Our graphics-oriented notes (and a few selected slides) on the rest of the conference are included inside, if you dare to take the red pill.

Cini se da ce sljedeci radeoni dolazit u zasebnim kucistima sa vlastitim napajanjima.
E sad nije mi jasno kako ce ostvarit podatkovnu vezu preko kabela sa cpuom bez dodatnih latencija?

nece dolazit u zasebnikm kucistima, nego samo razvijaju to... R600 je već poprilično gotova stvar ovo ce biti za dalje...

podatkovna veza? možda će biti pci-e kartica i specijalan port...

a možda su u šumi...

[nicko]

A možda je to Inqurier...

[drago7]

Evo i friške viijesti u vezi r600
Vele da imaju problema sa pregrijavanjem cipa, i da klasicna hlađenja ovdje ne pomažu, cak su angazirali spec firmu koja se bavi izradom spec nano materijala za hladnjake, tak da nece uspjet na vrijeme izbacit karticu

Ali, trebo bi napisat nešto i na hrvatskom, a ne samo copy paste

Ja nakon kaj par put pročitam nekaj kaj odlučim postati na ovom forumu, fino izvadim one dijelove koji su zanimljivi, tj. zanimljiviji od ostataka članka/ teksta. Na kraju denem link na sve skupa, da se vidi od kud, kaj i gde... Osim toga dobar dio linkova/vijesti/citata i tome sl., s ove (ali i drugih tema) je preuzet s nekih stranih članaka/recenzija/foruma, pa se niko ne buni. Uglavnom ako te moj način postanja nervira ili ne zadovoljava tvoje kriterije, imaš fino vagicu i prijavi post opciju, pa si daj oduška.
