I am a bit confused. When looking at GPU charts, the Radeon HD 5850 1 Gb is very slightly ranked higher than a GTX 460 1Gb. But the former has 1440 shader units and the latter only 336.

How is it possible that they perform almost identically?

Thnaks for your efforts elucidating an ignorant (attempting to build his first computer).

nvidia runs their stream processors at higher clock rates then ATI (and the GPU core). that's how an Nvidia card with 64 processors (9600GT) can keep up/outperform an ATI with 320 (3870). regardless, you can't use specs to compare ATI and Nvidia, or even different series like ATI 3xxx series to ATI 5xxx series cards. Architecture changes with each series and ATI and Nvidia build their cards in different ways. Your best bet is to simply compare third party benchmarks.

The stream processors used by nvidia runs on CUDA technology and gives parallel processing.So it has more performance benefits over a normal stream processor.

All GPUS us parallel processing. It tends to be a difference in clock speed and volumn of parallel processing. Its like AMD and Intel, CPUs run a different speeds but a slower clocked I7 can beat a faster clocked Phenom II
