Nvidia Fermi: GF100 tech roundup - Update: Mass production of Geforce GTX400 in Q2
At the CES in Las Vegas Nvidia is showing the new Fermi based GF100. Pc Games Hardware recapitulates the pieces of technical information that have been revealed up to now.
Nvidia is preparing the next green strike on the graphics card market. The engineers are working to finalize the GF100. At the moment the current version of the Fermi based device is presented at the CES in Las Vegas. Although Nvidia hasn't released much information about the new card yet, there nevertheless are several pieces of information available. PC Games Hardware summarizes what is currently known about the next green graphics hit.
GF100: The size
According to a post at Nvidia's Facebook site the GF100 will be 10.5 inches long and thus have the same size as graphics card of the Geforce GTX 200 series. Converted to the metric system this would mean that the Fermi card is 26.7 centimeters long - slightly shorter than the GTX 295 (27 centimeters) and the Radeon HD 5870 (28 centimeters).
GF100: Tech specs
What we do know up to now is that the GF100 is supposed to have three billion transistors. Furthermore another post at Nvidia's Facebook site says that the Fermi card offers hardware support for GPU overvoltaging for extreme overclocking. From the latest pictures of the demo systems shown at the CES we can also see that the GF100 supports 3-way SLI (since Nvidia is running such systems in Las Vegas), has no backplane like Fermi based Tesla cards and has one 6-pin and one 8-pin power connector - thus the card can draw up to 300 watt.
Given the facts that there is a video showing Nvidia's card running the Unigine DirectX 11 benchmark and that Nvidia is showing a tech demo, called Supersonic Sledge, that utilizes hardware tessellation (a DX11 feature) at the CES, it is quite certain that the GF100 will support the latest DirectX version.
GF100: New Anti-Aliasing mode?
Via Facebook Nvidia announced that the GF100 will support a brand-new anti-aliasing mode. But Nvidia doesn't reveal anything more than 32x Anti-Aliasing, so it is unclear how the sample rate is achieved. It's a matter of speculation if Nvidia makes the modes that are currently available in combination with additional tools like Nhancer only a officially supported part of the Geforce software or creates a new 32x mode.
Update: February 19, 2010
During the announcement of the latest quarterly figures of Nvidia CEO Huang mentioned the mass production of the GF100/Fermi. Accordingly the production will be intensified in the second quarter - and not for a single product only. Nvidia intends to spread the graphics cards based on the Fermi architecture over several price and product categories like Tesla, Quadro and Geforce. Since Tesla and Quadro products are usually more expensive than Geforce graphics cards, even a single Fermi derivate would match this announcement.
The presentation of the Geforce GTX 480/470 is in general expected for Cebit 2010 - up to now it is not clear if this will happen behind closed doors or for the public.
