Necroman:Vyrobit "jen tak" jadro, ze ktereho orezeme casti pro GPGPU a vydame to jako novou herni kartu, to je hodne zbesily napad! Ono jen to odebrani tranzistoru je prace na nekolik mesicu pro mnoho inzenyru. Mimo to, proc by se s tim delali? Vyteznost by si moc nezlepsili, ony GPGPU only obvody delaji beztak ani ne 10% plochy, tudiz TDP by u potencialni 512 jadrove karty stejne vesele sahalo nad 300W a vyteznost by byla seredna. I ted se ukazuje, ze ani GF106 nelze vydat s plne aktivovanym cipen 256 jader, jen se 192 - ta vyteznost je i u polovicniho die nizka. Vtipne jinak, ze v prubehu rijna uz zacnou prichazet karty HD6xxx, tedy v dobe, kdy nVidia konecne uzavre sve Fermi portfolium

The top GF106 card, the GTS450 is expected to sport specs of 1GB GDDR5 running at 3,760MHz on a 128-bit bus, supported by a quietly confident 789MHz core. Should this top GF106 card have the speculated full complement of 256 Cuda Cores then it could initially be faster than the un-optimised GTX460, depending on shader design. However in theory it would fall short of the GTX460 by about 12%, if both cards were optimised (going by cuda count and reference speeds), not that reference will mean much for GF106 and GF108. As for Compute Capability, and its effect on crunching, who knows, but that’s the point – wait and see.

no-X píše:Mně GF106 přijde jako půlka GF104 po stránce SM bloků (192 SPs, 32 TMUs) a půlka GF100 po stránce řadiče, ROPs a sběrnice (192 bit, 24 ROPs).

GF100 má 530mm², GF104 má 367mm², GF106 má mít 238mm². Polovina GF100 to být nemůže, na to je příliš malá.

Poměr velikosti GF104 a GF106 je 1,54

G94 byla také po stránce počtu SM bloků polovinou G92, přičemž ROPs a sběrnice zůstaly širší. Poměr jejich rozměrů je 1,48.

To je hodně podobné, ne?

At a rendezvous in San Francisco, Avner Ronen told us the decision to abandon Tegra 2 was about performance and nothing more: "The major problem we had with the Tegra 2 was support for high-profile HD playback," he said. "You can do high-profile VC-1 with Tegra 2, but not H.264." It was a problem of bitrate, he told us, and while NVIDIA's dual-core Tegra T20 was apparently not up to the task, the team had internally tested Intel's CE4100 decoding streams at up to 90 megabits per second.

NVIDIA Tries To Poison Media With Lead Painted Coffee Mugs

Legit Reviews just made it out to San Jose for the 2010 NVIDIA GPU Technology Conference and the swag bag this year was rather interesting. Inside a plastic tote that is a made from four 20oz recycled plastic bottles and listing a url for their 'Green Initiative' at GTC was a Coffee Mug for the conference. The said coffee cup had a warning sticker stating that the decorations on the exterior of the product contains lead, lead compounds and/or cadmium. Doesn't sound too environmentally friendly to us and the companies 'Green Initiative' states that "Gifts for participants are durable, useful, minimally packaged (incorporating recycled content packaging), made from non-toxic materials, and incorporate the highest practical post-consumer recycled content." I guess the person that ordered the mug didn't know about this initiative. Don't worry we won't be licking the outside of the cup, but we certainly won't be drinking any kool-aid from it either this week. Stay tuned for show coverage!
