Its not important they are fully functionnal or work at low speed or different speed, they just need them to be working for start the tests. This said, it is fully possible they have got the first raw of full tested chips when Nvidia is starting the production ramp up. They need a lot of thoses cores for start testing and building the system, because you cant simulate each parts as a valid results for the interconnect and the software ofc.

    Yes they are some sillicon ready, as i was mention, they release the K20 in less of 2 months, i hope they have start product them lol .
    I am pretty sure those 1000 cards were not engineering samples. Titan is complete with 18,688 cards. And the specs are more a bit more impressive than the recent information on the cards suggest.

    According to HPCWire, the Teslas run at 732 MHz. Taking the claimed 27 PFlop/s theoretical peak and factoring in the CPU flops (2,63PFLOP/s for base clock, would be 2,99 PFlop/s for all core turbo clock), it is a 14 SMx GK110 version.

    14 SMx
    732 MHz
    6 GB GDDR5 @ 384Bit memory interface (clock still unknown)
    1.31 TFlop/s theoretical peak

    It's probably the top version of the K20 line"

    If your wondering, you can get these specs by dividing the amount of cards, by the amount of memory(112tb/ 18,688 cards) and also the given teraflop number gives the SMX.

    I can definitely see a gaming version running at 850-900mhz with all 15 smx clusters enabled.
