With twice the number of texture units, one would suspect that the 4850 performs much better than an 3870 right from the start (and conveniently you quote games with heavy texture loads....). Add 50% more pixel/vertex-shaders (96 vs 64, also the stream processor architecture in the 4850 may have seen some improvements) and your numbers (in whichever way they were generated) become reasonable.

Numerically, it MUST BE 800 SPUs, because each shader shader unit is capable of 2 FLOPS, and if there are 800 units, this means that Radeon HD 4850 with its 625MHz will hit exactly 1TFLOPS. That is AMD/ATI chose that specific frequency. Radeon HD 4870 with its 750MHz core will have 20% more processing power available and hits 1.2TFLOPS.
It is officially confirmed that both cards will have 1TFLOPs (unleashonetera.com).
