Looking at the slides, there is a dual BIOS switch on the card that allows to overclock the card on the fly. The default shipping clocks for the card is 830MHz core and 1250MHz memory and by switching to OC mode, the core clock becomes 880MHz but memory clock remains unchanged. However, the VGPU is increased from 1.17V to 1.175V and the TDP is increased from 375W to 450W. Do your own maths if that few percent improvement in gaming performance is worth the additional heat generated if you are a gamer but definitely, everything else is secondary it if you are going for the scores. Pricing is unknown for now.
