Tesla is supposed to be the most expensive SKU with the best GPU cherry picked cores, so considering that it may have only 448 SP, will mean that the consumer card will have the same SP count, I doubt that nVidia will use the best cores for consumer cards when the Tesla cards can be more profitable and mission critical. After all, nVidia can scale down and disable SP for cheaper SKU's and get some profits selling it for the regular consumer, pretty much the same bussiness tactics done before.
Unless for Tesla units they need to be within a 225 watt power envelope. Dont those boxes come in 4 and 8 GPU setups?? A single 225+ part part in a consumer machine is doable. 8 of them missing their power envelope can increase thermals greatly.
