According to chatter on the grapevine, Intel's first-ever DG1 GPU will be just 23% more powerful than Tiger Lake graphics and is currently struggling to meet its TDP envelope of 25W. Oh and notice the rumor tag and its implications, or forever hold thy silence. Intel's Xe GPUs have captured the imaginations of tech enthusiasts everywhere and practically all of us cant wait for the duopoly to become a triopoly. But if this rumor is true, (and this is the second time we are hearing something along these lines) there might be more than a few hiccups before that dream can become a reality.

The interesting thing about this rumor is that DG1 was obviously only going to be a training vehicle for Intel to cut its teeth into the world of dGPUs but we have previously heard rumors that Intel wasn't able to get any AIB on board to trial run DG1. While this is understandable considering no AIB would want to be the guinea pig for Intel to learn the ropes, another potential reason for this refusal has emerged: Intel unable to control the TDP envelope of the platform.
