NVIDIA Previews GF100 Features and Architecture
MojoKid writes "NVIDIA has decided to disclose more information regarding their next generation GF100 GPU architecture today. Also known as Fermi, the GF100 GPU features 512 CUDA cores, 16 geometry units, 4 raster units, 64 texture units, 48 ROPs, and a 384-bit GDDR5 memory interface. If you're keeping count, the older GT200 features 240 CUDA cores, 42 ROPs, and 60 texture units, but the geometry and raster units, as they are implemented in GF100, are not present in the GT200 GPU. The GT200 also features a wider 512-bit memory interface, but the need for such a wide interface is somewhat negated in GF100 due to the fact that it uses GDDR5 memory which effectively offers double the bandwidth of GDDR3, clock for clock. Reportedly, the GF100 will also offer 8x the peak double-precision compute performance as its predecessor, 10x faster context switching, and new anti-aliasing modes."
Because I needed convincing not to buy a 5890 today.
Anandtech also has an article up about the GF100. They generally have very well written, in-depth articles: http://www.anandtech.com/video/showdoc.aspx?i=3721
280W power drain, 550mm^2 chip size => no thanks, i'll pass.

So we've had this long history with nvidia part numbers gradually increasing. 5000 series, 6000 series, etc. up until the 9000 series. At that point they needed to go to 10000, and the numbers were getting a bit unwieldy. So understandably, the decided to restart with the GT100 series and GT200 series. So now instead of continuing with a 300 series, we're going back to a 100. So we had the GT100 series and now we get the GF100 series? And GF? Serieously? People already abbreviates GeForce as GF, so now when someone says GF we can't be sure what they are talking about. Terrible marketing decision IMHO.
Compared to the watts you would need to run a Xeon or Opteron to get the same double precision performance it's a huge bargain.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
But most of us will compare it with the watts needed to run two high end AMD cards
I think he's talking about dissipation of such a large amount of power in such a small package size.
The die size is barely larger than a square inch, and 280W is a tremendous amount of energy to dissipate through it.
Cooling these things is going to be an issue for sure.
Now that graphics are largely stagnant in between console generations, the PC's graphics advantages tend to be limited to higher resolution, higher framerate, anti-aliasing, and somewhat higher texture resolution. If the huge new emphasis on tesselation in GF100 strikes a chord with developers, and especially if something like it gets into the next console generation, games may ship with much more detailed geometry which will then automatically scale to the performance of the hardware on which they're run. This would allow PC graphics to gain the additional advantage of having an order of magnitude increase in geometry detail, which would make more of a visible difference than any of the advantages it currently has, and it would occur with virtually no extra work by developers. It would also allow performance to scale much more effectively across a wide range of PC hardware, allowing developers to simultaneously hit the casual and enthusiast markets much more effectively.
