Although Intel has not shown no power connectors in his Teaser Arc Desktop "Limited Edition", Petersen confirmed that in fact this is a standard ATX video card. According to Intel ATX 3.0 specifications, the new PCIe Gen5 power connector is used only to the graphics processors with a capacity above 300 W, so it can be assumed that this card has a lower TDP / graphical power.
During the interview with Hothardware, Peterson demonstrated a full-size desktop video card with a PCIE X16 interface. Almost probably it was a prototype. In fact, it may not even be a graphical processor ARC, but you can wonder that this card did at its desk during an interview associated with "ARC". Not to mention the fact that Intel does not plan any other XE-HPC / HC cards with the PCIE interface, at least officially.
This prototype of the board clearly has three 8-pin power connector, each of which is technically capable of providing a power of 150 W. The distance between the connectors also indicates this on the engineering board for evaluation. This is not at all like the Arc Alchemist Arc prototype fees, which have been observed for several months:
Therefore, it is possible to ask if this is the successor to Alchemist? In the end, Intel confirmed that Battlemage aimed at an even higher Enthusiast performance segment. But then you can ask, why use three 8-pin power connector if the company has just announced ATX 3.0 specifications, which determine the graphics processors with a power of 300 W + with a new connector, which will actually replace all three standard 8-pin connector.
However, it is impossible to deny that it was an interview about the ARC graphic processor, and the prototype of the board was shown shortly after the segment dedicated to the teaser video for desktop PCs. It is not clear, however, why Petersen decided to show this card at this moment.
