This is a good read and not only highlights some already known and perhaps unknown details about Fermi's claimed performance, yields, and speculated pricing (albeit some rather vaguely), it tends to dispel many of the rumors about Nvidia intentionally sabotaging ATI performance in games. In fact it reveals in some cases they've also improved ATI performance literally for free.

It looks to me like Fermi is going to be well worth the wait. http://www.bjorn3d.com/read.php?cID=1778

From nVidia reps:

Fermi has 16 tessellation units 1 tessellation unit per SM. So that equals 1 tessellation unit per 32 shaders Seeing upwards to 3x-6x performance advantage in tessellation benchmarks. 4 Triangles per clock setup engine ((4x improvement over previous engines which do it at 1x)) 1.5 Gigabytes of Memory 512 Cuda Cores 384 bit Bandwith Bus GDDR5 TMUS are decoupled and run connected to the SMs rather than the shaders. Increasing efficiency. 64 TMUS 48 ROPS Polymorph Tessellation Engine: Vertex Fetch -> Tessellator -> Viewport Transform -> Atribute setup -> Stream Output The tessellator units are hardware. But the entire pipeline is programmable. Improved 8x MS performance should be on AVG about 10-15% max slower than 4x. 32x CSAA 8x MS + 24 CSAA. Transparency AA now works with Coverage Samples. In previous generious 16x CSAA would only provide 4x color samples for Transparency AA. Now its covered by coverage samples as well. Shader engine improved better cache. Better units. More units = Improved PhysX Support. Unlike previous generation Nvidia hardware GF100 is "very" focused on geometry where as in the past Nvidia has primarily been focused on pixel Fidelity.

Anandtech and [H]ard|OCP have the same stuff as well.

I retract some of what I said before. It does seem like it's going to be worth the wait, performance-wise at least. However, I'm still not going to buy it if it runs too hot, if it consumes too much power, and if it costs too much.

Looks pretty impressive. I'm just almost afraid to hear what its going to cost.

Maybe as far as the white paper stuff goes, but I chose Bjorn's article because they know the Nvidia staff pretty well and were invited to a private meeting in Vegas with them. Hence the details other than the tech stuff such as the dispelling of rumors about sabotaging ATI performance.
