Pare che la risposta Nvidia ad rv740@40nm non si farà attendere: gt21x a 40nm secondo l'amministratore di beyond3d

risponde ad un utente che gli chiede perchè Nvidia non passa subito alle ddr5:

Same reason why they didn't go for 55nm immediatly: they likely think the DRAM manufacturers couldn't sustain the necessary capacity for two vendors to switch their entire line-up to it at the same time. In addition to that, they obviously didn't have GDDR5 IP on 65/55, and so releasing their very first product on 40nm with a memory technology they haven't used before is a bit more risky than necessary...

GT21x is GDDR3 all the way except for GT212, while GT3xx-or-whatever-the-hell-it's-called is likely GDDR5 all the way with no exception, IMO.

qui quelle che dovrebbero essere le specifiche del primo chip @40nm di Nvidia:

RV740 is a direct competitor to GT216: 512MiB 128-bit 1.8GHz+ GDDR5/16ROPs vs 768MiB 192-bit 1.2GHz GDDR3/12ROPs (and maybe 384MiB for OEMs?) - I don't know the TMU/ALU specs of either however, but ]RV730;RV770] and ]G94;GT200[ seems like a fair bet to me before considering clock speeds; the reason why I say GT200[ instead of G92] is that the absolute maximum I would be willing to seriously consider for GT216 is 32TMUs/160SPs.
