ATI R520 ... dost odvazne specifikacie. Uvidime

[ot]Bitboys boli velmi blizko, ale Infineon mal v tom case financne problemy a odniesla si to (nielen) EDRAM divizia. Takze im zrazu nemal kto dodavat "kremik"...[/ot]

http://www.theinquirer.net/?article=23648

jj, všude se píše 32 nebo 24 pipelines, jenže nikde, jestli je to 32 pixel pipelines nebo 32 shader pipelines :-( Zlatý časy, kdy 8 = pxl pips = shader pips = TMUs = ROPs

ATi R520 Launch On 26th July

Citace:

---

Over at Computex, we heard faintly that the next generation ATi R520 GPU will be launched on July 26th, a month later than NVIDIA G70 slated for full scale release later this month. Many of the NVIDIA partners have already received the G70 samples and are working hard to deliver their solutions on time so it will not be a paper launch definitely. So far ATi has quietly showed their important business partners a working R520 demo behind doors at Computex but it is a single card not Crossfired. The R520 card looks pretty much like a X850XT PE which is a dual slot solution but has a mosfet sink like the NVIDIA's and the PWM area is improved. The copper heatsink on the GPU is bigger if i can still remember correctly and there is a HDTV connector on the card too. ATi seems pretty confident about their R520 to match up and even surpass the NVIDIA G70 so we shall see about it.

Jestli je tohle pravda, tak budu mit zase zajimavy prazdniny, kdy se budu nekolik tydnu trapit tim, kterou kartu si poridit a pak si jako vzdycky vyberu tu spatnou...

Tohle je asi jediny pripad, kdy to maji fanATIci a nVIDIOTI jednodussi no ;D

A to jsem jeste slysel spekulace, ze nV ma v zaloze 32 pipeline bestii, ktera by mela prijit na Vanoce s 512MB pameti jako reakce na R520, takze to rozhodovani budes mit jeste tezsi.

ATI R520 scores 10K+ in 3Dmark05

Citace:

DESPITE WHAT people were claiming, the G70 will score better than 7800. The card never got the 7800 suffix based on its 3Dmark05 score and if it was number would end up significantly bigger. It's actually going to be quite better but still not as good as the "Fudo" R520.

We got some numbers from this card and it turns out that R520 scores more than 10000 in 3Dmark05. We still don't know its clock speeds but we know the score. For what we know Nvidia can not mach this with G70.

jestli tech 10k v 3dmarku05 je pravda, tak 512mb a 32 pipe bestie je uz ne na ceste, ale rovnou na dalnici :wink:

zda se mi dle rychlosti uvedeni g70, ze jde o lehce upravene odzkousene reseni a u 520 pujde o neco zcela noveho

Jestli je těch 10000 bodů pravda, tak R520 nemá 32 pixel pipelines ;-)

Presne. A pokud ma G70 neco pres 8k, tak bude tahle generace nejspis opet vyrovnana jako ta minula.

EDIT: No tak se zda, ze tento vysledek muze byt od Macci-ho, coz muze byt klidne i o 2.000 bodu vic, nez bude davat bezne dostupna verze, holt Inquirer :roll:

Nevím, čemu věřit, přeberte si to jak chcete, ale tohle je zatím nejpesimističtější článek o R520, jakej jsem četl:

http://www.penstarsys.com/editor/com...520/index.html

no nevim jestli nejpesimistictejsi, ale spis rika hodne o problemech s vyrobou ... ale to neustale odkladani uvedeni na trh to signalizovalo :-(

takze mozna bude nekdy bombasticka 520 s 10k v 3dmarku05 s hardwarovou podporou h.264, ale temer jiste bude lehce vylepsena 7800GTX s cca 8k v 3dmarku05

k h.264 - premiere na satu uz to zkusebne spustila a jsou prvni vysledky bez hardwerove akcelerace:

"So it is possible to decode this H264 on live , on my Athlon at 2000MHz it was ~10fps"

http://forum.doom9.org/showthread.ph...660#post663660

Ve skutečnosti zatím žádný odkládání nebylo. To co psali na Inquireru byly výmysly a domněnky tamějších redaktorů; už v březnu jsem měl potvrzený z nejmenovanýho zdroje, že R520 bude uvedená na konci června. Takže jestli to u ATi od začátku plánovali takhle, tak by přeložení na červenec (pokud to tak bude) bylo vůbec první. (když už je jasný, že karta v červnu nevyjde, tak se na mě nejmenovaný zdroj doufám nebude zlobit ;D )

Zdá se, že informace o problémech s výrobou R520 nepocházejí od ATi, ale od nVidie :roll:

Some sites on the net are claiming that R520 is the next NV30, has leakage problems and is pretty much falling apart. You can check such claims here. We know that information comes from Nvidia as it wants this kind of FUD about its competitor component out.

We can confirm that the first R520 silicon did had some problems and that chip is re-taped out again and most of the problems are gone. We confirm that 90 nanometres is a risky process, but it seems that ATI knows what it is doing. Even if ATI decides to go for 24 pipelines, the yields will be acceptable at least according to our usually very highly reliable sources.

Dokonce? Ze by nakonec jen 16-pipeline a 24 v zaloze?

Jde o to JAKÝCH pipeline, resp. co se tím myslí. Pixel pipeline? Pixel shaderů? Pxl + Vrtx pips. dohromady? Podle mě je naprosto zbytečný, aby R520 nabízela 32 "plných" pipeline (tím myslím něco jako X800*2), protože k čemu jí je vykreslení 32 pixelů za takt, když by ji tak stejně brzdil výkon shaderů, zixel-rate, bandwidth atp.

ATI Fights for Next-Gen R520 GPU Yields

http://www.xbitlabs.com/news/video/d...609093014.html

tahle pasaz mne zaujala:

"ATI is reportedly playing a waiting game with NVIDIA Corp., who is expected to release its NVIDIA GeForce 7800-series graphics processors shortly. Once the benchmarks of NVIDIA’s part code-named G70 are out by independent review web-sites, ATI is expected to finalize specifications, such as clock-speeds, of its next-generation RADEON product."

ATI Denies Rumoured Pixel Shader 3.0a Specification.

Citace:

---

ATI Technologies earlier this week denied rumours claiming that the company’s forthcoming graphics processor code-named R520 would support Pixel Shader 3.0a specification, as suggested by game-developer Zuxxes.


“To the best of my knowledge there is no Shader Model 3.0a or Pixel Shader 3.0a specifications,” Richard Huddy, European Developer Relations Manager, ATI told X-bit labs. “I suppose it’s also conceivable that MS might want to designate the Xbox 360 pixel shaders as ‘PS3.0a’.”

No R520 release until September

Citace:

Whilst sounding nervous, he is excited about Crossfire and R520, but we will not see R520 released until late summer (September). ATi plan to deliver a full family of cards in "Early Fall." He also stated that NVIDIA had a compelling prodcut in the form of 'dual graphics solution' but ATI were late to the market - and could not compete in this in Q2 and Q3.

We will be more than surprised if ATi manage to deliver R520 to the channel, in volume before the end of September - and with the stealth kill which NVIDIA appear to have executed in the past 24 hours with the 7800 being able to be available on launch date. ATi can not appear to execute another paper launch.

Ano, 26. červenec se zmiňuje často, ale dobře informovaní lidé tvrdí, že karta bude až koncem srpna nebo v září (resp. ATi by ji mohla uvést dřív, klidně i toho 26., ale dostupná bude až koncem léta). Je to až s podivem, když si uvědomíme, že funkční vzorky karet byly už v půlce února ;-)

http://www.driverheaven.net/zardon/01.jpg

Taky se diskutuje o tom, že celé zpoždění není (jen?) vinou výrobního procesu, ale především tkví v nedostupnosti rychlých pamětí, se kterými se pro R520 počítalo, takže ATi udělala ještě nějaké změny ohledně sběrnice/řadiče pro vyšší efektivitu. Jsem docela zvědavej, jestli na těhle zprávách bude něco pravdy :-)
