Check the perlin noise test in Vantage - it's pretty much a pure math test and the architectures are in a dead heat.

Also, take a look at the geometry shader heavy particle simulation test. This is supposedly a strong suit of the R6xx architecture yet it falls way behind. Just pointing out that you shouldn't get too caught up in marketing or theoretical numbers.....

Having said that, I fully expect HD4870 to be a more compelling option that HD3870 was. The pricing alone belies that possibility.
If I remember the RV670 loved vertex, was neutral on pixels and hated geometry (shaders).

More like tasks the compiler can split up properly but still, GS isn't widely used in current DX10 titles. The cloth simulation test is an eyedropper though.

I wonder if the cache for synchronization in every (cluster of MPs?) ALU of the G80+ helped here, considering RV670 has to reach the registers instead of the sideway cache.
