I watched this the other day, and I&#x27;ve been mulling over the observation that onboard graphics are getting more and more die-space.<p>On mobile, where discrete graphics are a rarity and power is a scarce resource, it makes sense to offload as much work onto the GPU as possible. 
Light it up, do the work as quickly as possible, then go back to sleep.<p>However I started wondering about what can be done for high-end desktops. I just bought an i7-6700K, and of course it&#x27;s paired with a very powerful discrete GPU.<p>So as I understand it, effectively this means about 1&#x2F;3 of that 6700K is just dark all the time. If there&#x27;s any GPU work to be done it will all be offloaded to the PCIe bus, not the onboard graphics.<p>How can we make use of that silicon in scenarios like that? Is there any advantages an onboard GPU has that can be leveraged over a discrete GPU? (Apart from power efficiency; which in my opinion is a non-issue when thinking about PCs with 800W+ power supplies.)<p>---<p>P.S: Of course all this would be moot if I had just bought the 5820K. Live and learn.
