just my thoughts.
I don't quite see a reasoning for the three card line-up in nv products (nv34, nv31, nv35), and each with two core clocks. Most surprising are nv31 and nv34 ultra with very comparable performance. yet for a low end card nv 34 ultra is very expensive (bga memory, high cost pcb, high power consumption) and with nv36 very soon it is getting very crowded.
here's what I think: having so much problems with nv30 on 0.13µ, they ran two low-end projects, pin-compatible, one on 0.15µ, one on 0.13µ, nv34 only purpose to have something to sell on nv31 pcb until yelds ramp up. considering nv31 is all but totally missing, as they get good yelds on it, and (sorry if i repeat myself) they run on the same pcb it will soon be cheaper for nvidia to sell nv31 chips then nv34.
All that makes nv34 a very temporary product with sub-par, "crappy", performace even by nv standards, soon to be replaced by nv31 on low-end as it was originally designed for. that makes understandable the performance gap to the gf4 ti.
of course all that holds if they can get good yelds on nv31. if it is the same "quality" design as nv30 they may not, and it may get cancelled like the other .13µ contemporary chip. in that case do you think they'll keep the nv34 or get replaced with a cut-down/lower-speed nv36?
