otazkou zostava, ako moc bude R580 uvedena papierovo .... a ako moc realne :\
Podle ATi bude dostupna hned v den vydani(a nizsi takty jadra i pameti tomu nasvedcuji, ze dostupnost bude podstatne lepsi nez u X1k), takze bych u nas cekal neco jako X1300, kterous mohl koupit cca 2-5 dni po oficialnim vypusteni ...
Re: G70 - G80 - Dualcore?
Tak růžově bych to neviděl, ale myslím, že za týden až deset dnů (od vydání) bude snadno dostupná.

Next generation NVIDIA GPU product details revealed
Citace:
It would seem that a few key NVIDIA partners have already been sampled with GeForce 7900, and they're currently working towards a hard launch planned for CeBIT 2006 in Hannover, Germany (9th through to 15th March), and if so, our money's would be on watching for announcements from NVIDIA, ASUSTeK, eVGA, XFX and possibly MSI, between the 9th and 11th March.
Unlike the launch of its GeForce 7800 GTX, the current plan seems that NVIDIA will launch both the faster GTX and GT variants at the same time.
The flagship single-card product GeForce 7900 GTX is claimed to be a 32 pixel processor part with a core GPU frequency of 700/750 MHz, and should ship with 1.1ns graphics RAM clocked at 800/900MHz.
Citace:
the money-shot is that a 700MHz NVIDIA GeForce 7900 is currently coming in at circa 13,000 3DM2K5's on an AMD Athlon 64 FX 60 system.

Re: G70 - G80 - Dualcore?
No bylo by to pekne, kdyby se jim to podarilo, ale:
1.. 750MHz dohromady s 32pixel pipelines zas tak moc neverim
2.. 1.1ns pameti budou asi slusne drahe
Kazdopadne, nejaka 650-700MHz karta s 32 pipelines, tomu bych uz veril a rekl bych, ze nebudu tak daleko od pravdy. Jestli k ni pridaji 1.1ns pameti, tak si zbytecne dost snizi vyteznost + zvysi cenu, ale zas na druhou stranu NV z duvodu pouheho pridavani pipelines (a tim neunosneho zatezovani pametoveho subsytemu) nema na vyber nez po 1.1ns sahnout.
Re: G70 - G80 - Dualcore?
Tu su nejake dalsie vysledky 3dmarkov, je tam x1800, x1900, 7900, samozrejma aj crossfire a aj SLI ->

Re: G70 - G80 - Dualcore?
Tak to je snuzka dohadu a co je horsi, tak i nesmyslu.
Uz jenom:
ATi RADEON X1900 XT 512MB (625MHz VPU / 1450MHz GDDR-3) (AMD A64 FX-57 2.8GHz) ~10,000 3DMarks for $549 (£311.04)
Kdyz dle vr-zone:
"More interestingly, we heard faintly that a early sample of X1900 XTX clocked at 500MHz scored 10.2K in 3DMark05 ", tedy teoreticky by XTcko (625MHz) melo dat az kolem 12k...
Nehlede na fakt, ze 7900 (ani samply) jeste nema nikdo v ruce...

NVIDIA G80
Citace:
We heard that G80 will be in time for launch in June during Computex and the process technology is likely to be 80nm at TSMC. In the recent statement, NVIDIA has said that they will be backing the 80nm "half-node" process by TSMC where it allows reduction of die size by 19%. We have previously mentioned that G80 is likely to take on the Unified Shader approach and supports Shader Model 4.0. G80 is likely to be paired up with the Samsung GDDR4 memories reaching a speed of 2.5Gbps.
According to Xpentor, NVIDIA G80 will make ATI stumble on April. Quad SLI itself can be implemented on a single card with two chips solution because it will carry the first dual core GPU ever with the support of DirectX10 and Shader Model 4.0. The development of G80 is also mentioned as being running very intensive since NVIDIA's acquisition over ULi. As for the upcoming G71, there will be 32pipes, increase in ROPs and a little speed bump over the core clock.
