Some other slide not posted here shows that the dual-gpu core into it are Vega 56. So, if setup properly for efficiency this pair can consume 250-270W on full load.
Well it has official TDP of 300W and requires two 8-pin power. It has it own site on amd too. Interestingly that memory bandwidth translates to 2Gbps hbm2s so it's the same speed but higher density as what radeon pro WX8200 uses.
